Red Bear OS — microkernel OS in Rust, based on Redox

Browse Source 
Derivative of Redox OS (https://www.redox-os.org) adding:
- AMD GPU driver (amdgpu) via LinuxKPI compat layer
- ext4 filesystem support (ext4d scheme daemon)
- ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG)
- Custom branding (hostname, os-release, boot identity)

Build system is full upstream Redox with RBOS overlay in local/.
Patches for kernel, base, and relibc are symlinked from local/patches/
and protected from make clean/distclean. Custom recipes live in
local/recipes/ with symlinks into the recipes/ search path.

Build:  make all CONFIG_NAME=redbear-full
Sync:   ./local/scripts/sync-upstream.sh

| Display server | Orbital: `recipes/gui/orbital/` | Userspace scheme-based display server |
| GPU/graphics stack | `recipes/libs/mesa/` | OSMesa + LLVMpipe (software only) |
| Boot config | `config/*.toml` | TOML hierarchy, include-based |
## BUILD COMMANDS
```bash
# Prerequisites (Linux x86_64 host)
# rustup + nightly-2025-10-03, cargo install just cbedgen, nasm, qemu-system-x86
# See docs/06-BUILD-SYSTEM-SETUP.md for distro-specific packages
# Configuration
echo 'PODMAN_BUILD?=0' > .config # Native build (no container)
echo 'PODMAN_BUILD?=1' > .config # Podman container build
# Build RBOS
make all # Build desktop config → harddrive.img
make all CONFIG_NAME=redbear-full # Full RBOS desktop + custom drivers
make all CONFIG_NAME=redbear-minimal # Minimal RBOS server
CI=1 make all CONFIG_NAME=redbear-minimal # CI mode (disables TUI, for non-interactive)
# Run
make qemu # Boot in QEMU
make qemu QEMUFLAGS="-m 4G" # With more RAM
make live # Build live ISO → rbos-live.iso
# Single recipe
./target/release/repo cook recipes/libs/mesa # Build one recipe
./target/release/repo fetch recipes/core/kernel # Fetch source only
make r.mesa # Make shorthand for cook
make cr.mesa # Clean + rebuild
# Clean
make clean # Remove build artifacts
make distclean # Remove sources + artifacts
```
## BUILD FLOW
```
make all
→ mk/config.mk (ARCH, CONFIG_NAME, FILESYSTEM_CONFIG)
→ mk/depends.mk (check host tools: rustup, cbedgen, nasm, just)
→ mk/prefix.mk (download/setup cross-toolchain if needed)
→ mk/fstools.mk (build cookbook repo binary + fstools)
→ mk/repo.mk (repo cook --filesystem=config/*.toml)
→ For each recipe: fetch source → apply patches → build → stage into sysroot
→ mk/disk.mk (create filesystem.img, harddrive.img, rbos-live.iso)
→ redoxfs-mkfs → redox_installer → bootloader embedding
```
## CONVENTIONS
- **Rust edition 2024**, nightly channel
- **rustfmt.toml**: max_width=100, brace_style=SameLineWhere
- **clippy.toml**: cognitive-complexity-threshold=100, type-complexity-threshold=1000
- **Recipe format**: TOML with `[source]` + `[build]` + optional `[package]`
- **Build templates**: `cargo`, `meson`, `cmake`, `make`, `configure`, `custom`
- **WIP recipes**: Must start with `#TODO` comment explaining what's missing
- **Custom configs**: Name with `my-` prefix (git-ignored by convention)
- **CI**: GitLab CI (`.gitlab-ci.yml`) at root + per-recipe; some have GitHub Actions
- **Syscall ABI**: Unstable intentionally. Stability via `libredox` and `relibc`
- **Drivers**: ALL userspace daemons via scheme system. No kernel-space drivers (except serio)
## ANTI-PATTERNS (THIS PROJECT)
- **DO NOT** suppress errors with `as any` / `@ts-ignore` — use proper `Result` handling
- **DO NOT** use `unwrap()` / `expect()` in library/driver code — pervasive anti-pattern (~14k instances)
- **DO NOT** modify kernel syscall ABI directly — use `libredox` or `relibc`
- **DO NOT** put drivers in kernel space — all drivers are userspace daemons
- **DO NOT** hardcode `/dev/` paths — use scheme paths (`/scheme/drm/card0`)
- **DO NOT** skip patches in WIP recipes — document what's missing with `#TODO`
## PATCH MANAGEMENT
All RBOS modifications to upstream files are kept separately in `local/patches/`.
### Structure
```
local/patches/
├── kernel/redox.patch # Applied to kernel source during build (symlinked from recipe)
├── kernel/P0-*.patch # Individual logical patches (for reference/merge)
├── base/redox.patch # Applied to base source during build (symlinked from recipe)
├── base/P0-*.patch # Individual logical patches
├── relibc/P3-*.patch # POSIX gap patches (eventfd, signalfd, timerfd, etc.)
├── installer/redox.patch # Installer ext4 support
└── build-system/
├── 001-rebrand-and-build.patch # Makefile, mk/*, scripts, build.sh rebranding
├── 002-cookbook-fixes.patch # src/ Rust fixes (fetch.rs, staged_pkg.rs, repo.rs, html.rs)
├── 003-config.patch # config/*.toml changes (os-release, hostname, redbear-full)
└── 004-docs-and-cleanup.patch # README, CONTRIBUTING, LICENSE, deleted upstream files
```
### Protection Mechanism
1. **Recipe patches** (`kernel/redox.patch`, `base/redox.patch`): Canonical copy lives in
`local/patches/`. The recipe directory contains a **symlink** to it:
```
recipes/core/kernel/redox.patch → ../../../local/patches/kernel/redox.patch
recipes/core/base/redox.patch → ../../../local/patches/base/redox.patch
```
The build system follows symlinks transparently. Patches are never touched by `make clean`
or `make distclean`. Only `local/` modifications affect them.
2. **Build-system patches**: Generated via `git diff` against the upstream base commit.
These serve as a backup — the working tree already has patches applied (via git commits).
If upstream update via rebase fails, these can be applied from scratch.
3. **Custom recipes**: Live entirely in `local/recipes/` with symlinks into `recipes/`:
```
recipes/drivers/linux-kpi → ../../local/recipes/drivers/linux-kpi
recipes/gpu/amdgpu → ../../local/recipes/gpu/amdgpu
recipes/system/firmware-loader → ../../local/recipes/system/firmware-loader
... etc
```
### Scripts
| Script | Purpose |
|--------|---------|
| `local/scripts/apply-patches.sh` | Apply all build-system patches + create recipe symlinks |
| `local/scripts/sync-upstream.sh` | Fetch upstream + rebase RBOS commits + verify symlinks |
### Updating from Upstream
```bash
# Automated (preferred):
./local/scripts/sync-upstream.sh # Rebase RBOS onto latest upstream
./local/scripts/sync-upstream.sh --dry-run # Preview conflicts first
# Manual:
git remote add upstream-redox https://github.com/redox-os/redox.git # once
git fetch upstream-redox master
git rebase upstream-redox/master # replays RBOS commits on new upstream
# Nuclear option (if rebase fails badly):
git rebase --abort
git reset --hard upstream-redox/master
./local/scripts/apply-patches.sh --force # apply from scratch via patch files
```
## AMD-FIRST INTEGRATION PATH
See `local/docs/AMD-FIRST-INTEGRATION.md` for the full plan.
**Target**: AMD64 bare metal, AMD GPU (RDNA2/RDNA3). Intel second.
**amdgpu is 6M+ lines — 18x larger than Intel i915. LinuxKPI compat approach mandatory.**
### Bare Metal Boot Status
| Component | Status | Detail |
|-----------|--------|--------|
| UEFI boot | ✅ | x86_64 bootloader functional |
| AMD CPUs | ✅ | Ryzen Threadripper 128-thread verified |
| ACPI | ⚠️ Incomplete | Framework AMD 7040 crashes on unimplemented function |
| x2APIC/SMP | ✅ | Multi-core works |
| IOMMU | ❌ | No AMD-Vi support |
| AMD GPU | ❌ | Only VESA/GOP, no acceleration |
### Phased Roadmap
| Phase | Duration | Delivers |
|-------|----------|----------|
| P0: Fix ACPI for AMD | 4-6 weeks | Boots on modern AMD bare metal |
| P1: Driver infrastructure | 8-12 weeks | redox-driver-sys + linux-kpi + firmware-loader |
| P2: AMD GPU display | 12-16 weeks | redox-drm + AMD DC modesetting → scheme:drm |
| P3: POSIX + input | 4-8 weeks | relibc gaps + evdevd (parallel with P1/P2) |
| P4: Wayland compositor | 4-6 weeks | Smithay Redox backends |
| P5: Full amdgpu | 16-24 weeks | Complete GPU driver via LinuxKPI (parallel) |
| P6: KDE Plasma | 12-16 weeks | Qt6 → KDE Frameworks → KWin → Plasma Shell |
**Total to KDE Plasma on AMD**: ~52 weeks (~12 months) with 2 developers.
### Critical Path
```
P0 (ACPI boot) → P1 (driver infra) → P2 (AMD display) → P4 (Wayland) → P6 (KDE)
P3 (POSIX+input) ──┘
P5 (full amdgpu, parallel)
```
### New Crates Needed
1. `redox-driver-sys` — Safe Rust wrappers for scheme:memory, scheme:irq, scheme:pci
2. `linux-kpi` — C headers translating Linux kernel APIs → redox-driver-sys
3. `redox-drm` — DRM scheme daemon (AMD DC port)
4. Firmware loader daemon — scheme:firmware for AMD GPU blobs
All custom work goes in `local/` — see `local/AGENTS.md` for overlay usage.
## NOTES
- Build requires Linux x86_64 host, 8GB+ RAM, 20GB+ disk
- QEMU used for testing (make qemu). VirtualBox also supported
- The `repo` binary (cookbook CLI) may crash with TUI in non-interactive environments — use `CI=1`
- No git submodules — external repos managed via recipe source URLs and repo manifests
- File `INTEGRATION_REPORT.md` contains detailed integration status from a previous analysis

# Contributing to Red Bear OS
**Thank you for your interest in contributing to Red Bear OS!**
This document will outline the basics of where to start if you wish to contribute to the project. There are many ways to help us out and and we appreciate all of them. We look forward to **your contribution!**
**Please read this document until the end**
## Code Of Conduct
We follow the [Rust Code Of Conduct](https://www.rust-lang.org/policies/code-of-conduct).
## License
In general, your contributions to Red Bear OS are governed by the [MIT License](https://en.wikipedia.org/wiki/MIT_License). Each project repository has a `LICENSE` file that provides the license terms for that project.
Please review the `LICENSE` file for the project you are contributing to.
[This](https://doc.redox-os.org/book/philosophy.html) page we explain why we use the MIT license.
## Contribution Terms
When making a contribution you agree to the following terms:
- I understand these changes in full and will be able to respond to review comments.
- I have read the [Developer Certificate of Origin](https://developercertificate.org/) and certify my contribution under its conditions.
## AI Policy
Red Bear OS does not accept contributions generated by LLMs ([Large Language Models](https://en.wikipedia.org/wiki/Large_language_model)), sometimes also referred to as "AI". This policy is not open to discussion, any content submitted that is clearly labelled as LLM-generated (including issues, merge requests, and merge request descriptions) will be immediately closed, and any attempt to bypass this policy will result in a ban from the project.
## Chat
You can join in our chat platforms to discuss development, issues or ask questions.
### [Matrix](https://matrix.to/#/#redox-join:matrix.org)
Matrix is the official way to talk with the Red Bear OS team and community (these rooms are English-only, we don't accept other languages because we don't understand them).
Matrix has several different clients. [Element](https://element.io/) is a commonly used choice, it works on web browsers, Linux, MacOSX, Windows, Android and iOS.
If you have problems with Element, try [Fractal](https://gitlab.gnome.org/World/fractal).
- Join the [Join Requests](https://matrix.to/#/#redox-join:matrix.org) room and send a message requesting for an invite to the Redox Matrix space (the purpose of this is to avoid spam and bots).
- #redox-join:matrix.org (Use this Matrix room address if you don't want to use the external Matrix link)
(We recommend that you leave the "Join Requests" room after your entry on the Red Bear OS space)
If you want to have a big discussion in our rooms, you should use a Element thread, it's more organized and easy to keep track if more discussions happen on the same room.
You cand find more information on the [Chat](https://doc.redox-os.org/book/chat.html) page.
### [Discord](https://discord.gg/JfggvrHGDY)
We have a Discord server as an alternative for Matrix, open the #join-requests channel and send a message requesting to be a member (the purpose of this is to avoid spam and bots)
The Matrix messages are sent to Discord and vice-versa using a bot, but sometimes some Discord messages aren't sent to Matrix (if this happens to you join in our Matrix space above)
## [GitLab](https://gitlab.redox-os.org/redox-os/redox)
A slightly more formal way of communication with fellow Red Bear OS developers, but a little less quick and convenient like the chat. Submit an issue when you run into problems compiling or testing. Issues can also be used if you would like to discuss a certain topic: be it features, code style, code inconsistencies, minor changes and fixes, etc.
If you want to create an account, read the [Signing in to GitLab](https://doc.redox-os.org/book/signing-in-to-gitlab.html) page.
Once you create an issue don't forget to post the link on the Dev or Support rooms of the chat, because the GitLab email notifications have distractions (service messages or spam) and most developers don't left their GitLab pages open to receive desktop notifications from the web browser (which require a custom setting to receive issue notifications).
By doing this you help us to pay attention to your issues and avoid them to be accidentally forgotten.
If you have ready MRs (merge requests) you must send the links in the [MRs](https://matrix.to/#/#redox-mrs:matrix.org) room. To join this room, you will need to request an invite in the [Join Requests](https://matrix.to/#/#redox-join:matrix.org) room.
By sending a message in the room, your MR will not be forgotten or accumulate conflicts.
## Best Practices and Guidelines
You can read the best practices and guidelines on the [Best practices and guidelines](https://doc.redox-os.org/book/best-practices.html) chapter.
## Development Recommendations and Tips
- Copy-paste prevent and reduce typos
- Comment out configuration or code while testing is better than removal, to remember the testing conditions and prevent mistakes from forgotten logic
- Read the entire [Build System Reference](https://doc.redox-os.org/book/build-system-reference.html) and [Developer FAQ](https://doc.redox-os.org/book/developer-faq.html) pages
- Make sure your build system is up-to-date, read the [Update The Build System](https://doc.redox-os.org/book/build-system-reference.html#update-the-build-system) section if in doubt.
- If you want to make local changes in recipe sources it's recommended to automatic recipe source update, read [this](https://doc.redox-os.org/book/configuration-settings.html#local-recipe-changes) section to learn how to this for one or multiple recipes and [this](https://doc.redox-os.org/book/configuration-settings.html#cookbook-offline-mode) section for all recipes.
- If you want to make changes to system components, drivers or RedoxFS you need to manually update initfs, read [this](https://doc.redox-os.org/book/coding-and-building.html#how-to-update-initfs) section to learn how to do that.
- If some program can't build or work, something can be missing/hiding on [relibc](https://gitlab.redox-os.org/redox-os/relibc), like a POSIX/Linux function or bug.
- If you have some error on QEMU remember to test different settings or verify your operating system (Pop_OS!, Ubuntu, Debian and Fedora are the recommend Linux distributions to do testing/development for Red Bear OS).
- Remember to log all errors, you can use the following command as example:
```sh
your-command 2>&1 | tee file-name.log
```
- If you have a problem that seems to not have a solution, think on simple/stupid things. Sometimes you are very confident on your method and forget obvious things (very common).
- If you want a quick review of your Merge Request, make it small.
- If your big Merge Request is taking too long to be reviewed and merged try to split it in small MRs. But make sure it don't break anything, if this method break your changes, don't shrink.
## Style Guidelines
### Rust
Since **Rust** is a relatively small and new language compared to others like C and C++, there's really only one standard. Just follow the official Rust standards for formatting, and maybe run `rustfmt` on your changes, until we setup the CI system to do it automatically.
### Git
Please follow our [Git style](https://doc.redox-os.org/book/creating-proper-pull-requests.html) for pull requests.
## GitLab
### Identity
Once your GitLab account is created, you should add your Matrix or Discord username (the name after the `@` symbol) on the "About" section of your profile, that way we recognize you properly.
### Issues
We use issues to organize and track our current and pending work, to know how to create issues on the Redox GitLab read the [Filing Issues](https://doc.redox-os.org/book/filing-issues.html) page.
Once you create an issue don't forget to post the link on the Dev or Support rooms of the chat, because the GitLab email notifications have distractions (service messages or spam) and most developers don't left their GitLab pages open to receive desktop notifications from the web browser (which require a custom setting to receive issue notifications).
By doing this you help us to pay attention to your issues and avoid them to be accidentally forgotten.
You can see all issues on [this](https://gitlab.redox-os.org/groups/redox-os/-/issues) link.
### Pull Requests
Please follow [our process](https://doc.redox-os.org/book/creating-proper-pull-requests.html) for creating proper pull requests.

### Skill Levels
If you don't know programming:
- Test the [daily images](https://static.redox-os.org/img/) on your computer and add the report on the [Hardware Compatibility](https://gitlab.redox-os.org/redox-os/redox/-/blob/master/HARDWARE.md) list
- Monitor and warn developers if the [daily images](https://static.redox-os.org/img/) are outdated
- Use/test Redox and create issues for bugs or needed features (please check for duplicates first)
- Fix and write documentation
- Find or fix typos in configuration
If you don't know how to code in Rust but know other programming languages:
- Web development on the website (we only accept minimal JavaScript code to preserve performance)
- Write unit tests (may require minimal knowledge of Rust)
- Port C/C++ programs to Redox (read the `TODO`s of the recipes on the [WIP category](https://gitlab.redox-os.org/redox-os/redox/-/tree/master/recipes/wip))
- Port programs to Redox
If you know how to code in Rust but don't know operating system development:
- See the [easy](https://gitlab.redox-os.org/groups/redox-os/-/issues/?label_name[]=easy) issues
- See the "[good first issue](https://gitlab.redox-os.org/groups/redox-os/-/issues/?label_name[]=good%20first%20issue)" issues
- See the [help wanted](https://gitlab.redox-os.org/groups/redox-os/-/issues/?label_name[]=help%20wanted) issues (it's worth noting the skill level varies between projects, but a large subset of these should be approachable by contributors familiar with regular Rust/Unix application programming)
- Improve the package manager, or build system tooling like `redoxer` or `installer`
- Improve the [Ion](https://gitlab.redox-os.org/redox-os/ion) shell, or other high-level or mid-level projects
- Port Rust programs (also look for issues with the `port` label)
- Improve application compatibility in relibc by e.g. implementing missing POSIX/Linux functions
If you know how to code in Rust, and have experience with systems software/OS development:
- Familiarize yourself with the repository layout, code, and build system
- Update old code to remove warnings
- Search for `TODO`, `FIXME`, `BUG`, `UNOPTIMIZED`, `REWRITEME`, `DOCME`, and `PRETTYFYME` and fix the code you find
- Look in general for issues with the following labels: `critical`, `help wanted`, `feature`, `enhancement`, `bug` or `port`
- Improve internal libraries and abstractions, e.g. `libredox`, `redox-scheme`, `redox-event` etc.
- Help upstream Redox-specific functionality to the Rust ecosystem
- Improve Redox's automated testing suite and continuous integration testing processes
- Improve, profile, and optimize code, especially in the kernel, filesystem, and network stack
- Improve or write device drivers
For those who want to contribute to the Redox GUI, our GUI strategy has changed.
- We are improving the [Orbital](https://gitlab.redox-os.org/redox-os/orbital) display server and window manager, you can read more about it on [this tracking issue](https://gitlab.redox-os.org/redox-os/redox/-/issues/1430).
- OrbTk is in maintenance mode, and its developers have moved to other projects such as the ones below. There is currently no Redox-specific GUI development underway.
## Priorities
You can use the following GitLab issue label filters to know our development priorities on the moment:
- [Critical](https://gitlab.redox-os.org/groups/redox-os/-/issues/?label_name[]=critical)
- [High-priority](https://gitlab.redox-os.org/groups/redox-os/-/issues/?label_name[]=high-priority)
- [Medium-priority](https://gitlab.redox-os.org/groups/redox-os/-/issues/?label_name[]=medium-priority)
- [Low-priority](https://gitlab.redox-os.org/groups/redox-os/-/issues/?label_name[]=low-priority)
## Roadmap
We use tracking issues for the goals in our roadmap, you can see them in the filter below:
- [Tracking issues](https://gitlab.redox-os.org/groups/redox-os/-/issues/?label_name[]=tracking%20issue)
## RFCs
For more significant changes that affect Redox's architecture, we use the [Request for Comments](https://gitlab.redox-os.org/redox-os/rfcs) repository.
## Build System
To download the build system use the following commands:
(You need to have [curl](https://curl.se/) installed on your system)
```sh
curl -sf https://gitlab.redox-os.org/redox-os/redox/raw/master/podman_bootstrap.sh -o podman_bootstrap.sh
```
```sh
time bash -e podman_bootstrap.sh
```
To start the compilation of the default recipes run the command below:
```sh
make all
```
In case your operating system does not use SELinux, you must set the `USE_SELINUX` to `0` when calling `make all`, otherwise you might experience errors:
```sh
make all USE_SELINUX=0
```
You can find the build system organization and commands on the [Build System](https://doc.redox-os.org/book/build-system-reference.html) page.
## Developer FAQ
You can see the most common questions and problems on the [Developer FAQ](https://doc.redox-os.org/book/developer-faq.html) page.
## Porting Software
You can read how to use the Cookbook recipe system to port applications on the [Application Porting](https://doc.redox-os.org/book/porting-applications.html) page.
**Always verify if a recipe for your program or library already exist before porting to not break the build system with a recipe duplication or waste time.**
## Libraries and APIs
You can read the [Libraries and APIs](https://doc.redox-os.org/book/libraries-apis.html) page to learn about the libraries and APIs used in Redox.
## Visual Studio Code (VS Code) Configuration
To learn how to configure your VS Code to do Redox development please read the information below the [Visual Studio Code Configuration](https://doc.redox-os.org/book/coding-and-building.html#visual-studio-code-configuration) section.
## References
We maintain a list of wikis, articles and videos to learn Rust, OS development and computer science on the [References](https://doc.redox-os.org/book/references.html) page.
If you are skilled/experienced there's still a possibility that they could improve your knowledge in some way.
## Other Ways to Contribute
If you aren't good on coding, but you still want to help keep the project going, you can contribute and support in a variety of ways! We'll try to find a way to use anything you have to offer.
### Design
If you're a good designer, whether it's 2D graphics, 3D graphics, interfaces, web design, you can help. We need logos, UI design, UI skins, app icons, desktop backgrounds, etc.
- [Redox backgrounds](https://gitlab.redox-os.org/redox-os/backgrounds) - You can send your wallpapers on this repository.
- [Redox assets](https://gitlab.redox-os.org/redox-os/assets) - You can send your logos, icons and themes on this repository.
If you have questions about the graphic design, ask us on the [Chat](https://doc.redox-os.org/book/chat.html).

# Hardware Compatibility
> Hardware compatibility inherited from upstream Redox OS. See https://doc.redox-os.org/book/hardware-support.html for the latest upstream data.
This document tracks the current hardware compatibility of Red Bear OS.
- [Why are hardware reports needed?](#why-are-hardware-reports-needed)
- [What if my computer is customized?](#what-if-my-computer-is-customized)
- [Status](#status)
- [General](#general)
- [Contribute to this document](#contribute-to-this-document)
- [Template](#template)
- [Table row ordering](#table-row-ordering)
- [Recommended](#recommended)
- [Booting](#booting)
- [Broken](#broken)
## Why are hardware reports needed?
Each computer model has different hardware interfaces, firmware implementations, and devices, which can cause the following problems:
- Boot bugs
- Lack of device support
- Performance degradation
These reports helps us to fix the problems above, your report may help to fix many computers affected by the same bugs or missing drivers.
## What if my computer is customized?
If your desktop is customized (common) you should use the "Custom" word on the "Vendor" category and insert the motherboard and CPU vendor/model in the "Model" category.
A customized laptop should only be reported if you replaced the original CPU, report the CPU vendor and model in the "Model" category.
We also recommend to add your `pciutils` log as a comment on [this](https://gitlab.redox-os.org/redox-os/redox/-/issues/1797) tracking issue to help us with probable device porting.
## Status
- **Recommended:** The operating system boots with video, sound, PS/2 or USB input, Ethernet, terminal and Orbital working.
- **Booting:** The operating system boots with some issues or lacking hardware support (write the issues and what supported hardware is not working in the "Report" section).
- **Broken:** The boot loader don't work or can't bootstrap the operating system.
## General
This section contain limitations that apply to any status.
- ACPI support is incomplete (some things are hardcoded on the kernel to work)
- Wi-Fi and Bluetooth aren't supported yet
- AMD, NVIDIA, ARM, and PowerVR GPUs aren't supported yet (only BIOS VESA and UEFI GOP)
- I2C devices aren't supported yet (PS/2 or USB devices should be used)
- USB support varies on each device model because some USB devices require specific drivers (use input devices with standardized controls for more compatibility)
- Automatic operating system discovery is not implemented in the boot loader yet (remember this before installing Red Bear OS)
## Contribute to this document
To contribute to this document, learn how to create your GitLab account, follow the project-wide contribution guidelines and suggestions, please refer to the [CONTRIBUTING.md](./CONTRIBUTING.md) document.
### Template
You will use this template to insert your computer on the table.
```
| | | | | | | | |
```
The Redox image date should use the [ISO format](https://en.wikipedia.org/wiki/ISO_8601)
### Table row ordering
New reports should use an independent alphabetical order in the "Vendor" and "Model" table rows, for example:
```
| ASUS | ROG g55vw |
| ASUS | X554L |
| System76 | Galago Pro (galp5) |
| System76 | Lemur Pro (lemp9) |
```
A comes before S, R comes before X, G comes before L
Each "Vendor" has its own alphabetical order in "Model", independent from models from other vendor.

After user selects an option, it takes a long time for the "live" thing to load all the way to 647MiB. Once it does reach 647MiB, however, it dumps a bunch of logs onto the screen. Those logs also happen to be offset so that the leftmost portion of all text "exists" past the leftmost part of the screen, resulting in the logs being only partially visible. The logs appear to include (among other things) 1. "thread 'main' (1) panicked at acpid/src/acpi.rs:256:68: Called `Result::unwrap()` on an `Err` value: Aml(NoCurrentOp)"; 2. "thread 'main' (1) panicked at acpid/src/main.rs:147:39:acpid: failed to daemonize: Error `I/O error` 5"; 3. "... [@hwd:40 ERROR] failed to probe with error No such device (os error 19)..."; etc. |

Red Bear OS is a derivative of [Redox OS](https://www.redox-os.org) — a general-purpose, Unix-like, microkernel-based operating system written in Rust. It tracks upstream Redox, incorporating its improvements while adding custom drivers, filesystems, and hardware support.
## What's Different from Upstream Redox
| Component | Status | Detail |
|-----------|--------|--------|
| AMD GPU driver (amdgpu) | 🚧 In progress | LinuxKPI compat layer + AMD DC modesetting |
| ext4 filesystem | ✅ Compiles | Read/write ext4 alongside RedoxFS |
| ACPI for AMD bare metal | ⚠️ Partial | x2APIC, DMAR, IVRS, MCFG parsing |
| Custom branding | ✅ | Boot identity, hostname, os-release |
| POSIX gaps (relibc) | 🚧 In progress | eventfd, signalfd, timerfd, open_memstream |
## Project Structure
```
├── config/ # Build configs (TOML) — desktop, minimal, redbear-*
├── recipes/ # Package recipes (~100+ packages, 26 categories)
├── mk/ # Makefile build orchestration
├── src/ # Cookbook Rust tool (repo binary, cook logic)
├── local/ # ← Red Bear OS custom work (survives upstream updates)
│ ├── patches/ # Kernel, base, relibc patches
│ ├── recipes/ # Custom packages (drivers, GPU, system, branding)
│ ├── scripts/ # sync-upstream.sh, apply-patches.sh
│ ├── Assets/ # Branding (icon, boot background)
│ └── docs/ # Integration documentation
├── docs/ # Architecture guides
├── scripts/ # Helper scripts
└── Makefile # Root build orchestrator
```
## Build
Requires a Linux x86_64 host with Rust nightly, QEMU, and standard build tools. See the [Redox Build Instructions](https://doc.redox-os.org/book/podman-build.html) for full prerequisites.
```bash
make all CONFIG_NAME=redbear-full # Full desktop + custom drivers
make all CONFIG_NAME=redbear-minimal # Minimal server
make live CONFIG_NAME=redbear-full # Live ISO (rbos-live.iso)
make qemu # Boot in QEMU
```
## Sync with Upstream Redox
```bash
./local/scripts/sync-upstream.sh # Rebase onto latest Redox
./local/scripts/sync-upstream.sh --dry-run # Preview conflicts first
```
The `local/` directory is never touched by upstream updates. Recipe patches for kernel and base are symlinked from `local/patches/` — protected from `make clean` and `make distclean`.
## Resources
- [Upstream Redox website](https://www.redox-os.org)
- [Redox Book](https://doc.redox-os.org/book/)
- [Hardware Support](https://doc.redox-os.org/book/hardware-support.html)
- [Contributing](CONTRIBUTING.md)
## License
[MIT](./LICENSE) — same as upstream Redox OS.

# #
# Welcome to Red Bear OS! #
# #
# Red Bear OS (RBOS) is a derivative of Redox, an operating system written #
# in Rust, a language with focus on safety and high performance. Redox, #
# following the microkernel design, aims to be secure, usable, and free. #
# Redox is inspired by previous kernels and operating systems, such as #
# SeL4, MINIX, Plan 9, and BSD. #
# #
# Red Bear OS _is not_ just a kernel, it's a full-featured Operating System, #
# providing packages (memory allocator, file system, display manager, core #
# utilities, etc.) that together make up a functional and convenient #
# operating system. You can loosely think of it as the GNU or BSD ecosystem, #
# but in a memory safe language and with modern technology. #
# #
# The website can be found at https://github.com/vasilito/Red-Bear-OS-3. #
# #
# For things to try on Red Bear OS, please see #
# https://doc.redox-os.org/book/ch02-06-trying-out-redox.html #

# #
# Welcome to Red Bear OS! #
# #
# Red Bear OS (RBOS) is a derivative of Redox, an operating system written #
# in Rust, a language with focus on safety and high performance. Redox, #
# following the microkernel design, aims to be secure, usable, and free. #
# Redox is inspired by previous kernels and operating systems, such as #
# SeL4, MINIX, Plan 9, and BSD. #
# #
# Red Bear OS _is not_ just a kernel, it's a full-featured Operating System, #
# providing packages (memory allocator, file system, display manager, core #
# utilities, etc.) that together make up a functional and convenient #
# operating system. You can loosely think of it as the GNU or BSD ecosystem, #
# but in a memory safe language and with modern technology. #
# #
# The website can be found at https://github.com/vasilito/Red-Bear-OS-3. #
# #
# For things to try on Red Bear OS, please see #
# https://doc.redox-os.org/book/ch02-06-trying-out-redox.html #

#
# This server demo is insecure by design, we encourage you to get familiar into

#
# There should be rustysd already running, if not, you can try start it manually
# > sudo rustysd --conf /etc/rustysd
#
# You can also try running all daemons manually
# > sudo bash server.sh
#
# The server will start port 22 (ssh), 80 (static web) and 8081 (php)
# If you use the Red Bear OS build system, starting QEMU with `net=redir`
# should expose those port to 8022, 8080 and 8081.
# Try logging in to console via SSH with `ssh user@localhost -p 8022`

# 01 — Redox OS Architecture Overview
## 1. Microkernel Design
Redox is a **pure microkernel** written in Rust (~20-40k LoC). Only essential services
live in kernel space:
- Process and thread management
- Memory management (address spaces, page tables, grants)
- IPC via schemes (packet-based, io_uring-like SQE/CQE format)
- Context switching and scheduling
- Minimal kernel schemes: `debug`, `event`, `memory`, `pipe`, `irq`, `time`, `sys`, `proc`, `serio`
Everything else — drivers, filesystems, display server, networking — runs in **userspace**
as separate processes with isolated address spaces. Crashes are contained; no kernel panics
from driver bugs.
### Syscall Interface
The syscall ABI is **intentionally unstable**. Stability is provided by `libredox` and `relibc`.
On x86_64, syscalls use `int 0x80` with registers:
```
eax = syscall number
ebx, ecx, edx, esi, edi = arguments
eax = return value
```
Key syscalls: `open`, `close`, `read`, `write`, `seek`, `fmap`, `funmap`, `dup`, `fork`, `execve`,
`clone`, `mmap`, `munmap`, `mprotect`, `setrens`, `yield`.
### Userspace-ification Trend
Redox is actively moving POSIX functionality out of the kernel:
- **fork/exec** → userspace via `thisproc:` scheme
- **Signal handling** → userspace with kernel-shared page for low-cost `sigprocmask`
- **Process manager** → planned userspace daemon
This reduces TCB and allows faster iteration without kernel changes.
## 2. The Scheme System — Everything is a URL
Inspired by Plan 9. Every resource is accessed through a **scheme** — a named service
providing file-like operations (`open`, `read`, `write`, `fmap`).
### How Schemes Work
```
User program: open("/scheme/orbital:myapp/800/600/Title")
↓
Kernel: Routes to "orbital" scheme daemon
↓
Orbital: Creates window, returns file handle
↓
User program: write(fd, pixel_data) // renders to window
```
### Kernel Schemes
| Scheme | Purpose |
|--------|---------|
| `debug` | Debug output |
| `event` | epoll-like event notification |
| `irq` | Interrupt → message conversion |
| `pipe` | Pipe implementation |
| `memory` | Physical memory mapping |
| `time` / `itimer` | Timers |
| `proc` / `thisproc` | Process context |
| `sys` | System information |
| `serio` | PS/2 driver (kernel-space due to protocol constraints) |
### Userspace Schemes (Daemons)
| Category | Schemes | Daemon |
|----------|---------|--------|
| Storage | `disk.*` | ided, ahcid, nvmed |
| Filesystem | `file` | redoxfs |
| Network | `ip`, `tcp`, `udp`, `icmp` | smolnetd |
| Display | `display.vesa`, `display.virtio-gpu`, `orbital` | vesad, virtio-gpud, orbital |
| IPC | `chan`, `shm`, `uds_stream`, `uds_dgram` | ipcd |
| Audio | `audio` | audiorw |
| Input | `input` | inputd |
| USB | `usb.*` | usbhidd |
| Misc | `rand`, `null`, `zero`, `log`, `pty`, `sudo` | various |
### Scheme Registration
A daemon registers a scheme by:
1. `File::create(":myscheme")` — creates root scheme
2. Opens needed resources (`/scheme/irq/{irq}`, `/scheme/event`)
3. `setrens(0, 0)` — moves to null namespace (security sandbox)
4. Registers FDs with event scheme for async I/O
5. Loops: block on event → handle request → respond
### Namespace Isolation
- **Root namespace**: all processes start here
- **Null namespace**: process can only use existing FDs, cannot open new resources
- Namespaces inherited by children
- Enables sandboxing and privilege separation
## 3. Driver Model
All drivers are **userspace daemons** that access hardware through:
- **`iopl` syscall** — sets I/O privilege level for port I/O
- **`/scheme/memory/physical`** — maps physical memory (writeback, uncacheable, write-combining)
- **`/scheme/irq`** — converts hardware interrupts to messages
### Current Drivers
**Storage**: ided (IDE), ahcid (SATA), nvmed (NVMe), usbscsid (USB SCSI)
**Network**: e1000d (Intel GigE), rtl8168d (Realtek), ixgbed (Intel 10G)
**Audio**: ac97d, ihdad (Intel HD Audio), sb16d (Sound Blaster)
**Display**: vesad (VESA framebuffer), virtio-gpud (VirtIO 2D)
**Other**: pcid (PCI enumeration), acpid (ACPI), usbhidd (USB HID), inputd (input multiplexor)
### GPU Driver Status
- **No hardware-accelerated GPU drivers**
- Only BIOS VESA and UEFI GOP framebuffers
- Experimental Intel modesetting (Kaby Lake, Tiger Lake) — no acceleration
- AMD, NVIDIA, ARM, PowerVR: not supported
## 4. Orbital Display Server
Orbital is Redox's display server, window manager, and compositor — all in one userspace daemon.
### Window Creation (via Scheme)
```rust
// Open a window through the orbital scheme
let window = File::create("orbital:myapp/800/600/My Title")?;
// Read input events
let mut event = [0u8; 32];
window.read(&mut event)?;
// Write pixel data (RGBA)
window.write(&pixel_data)?;
window.sync_all()?;
```
### Supported Toolkits
- SDL1.2, SDL2 — games and emulators
- winit — Rust GUI abstraction (has Orbital backend)
- softbuffer — software rendering
- Iced, egui, Slint — via winit/softbuffer
### Graphics Stack
```
Application
↓ (SDL2 / winit / liborbital)
Orbital (display server + compositor)
↓ (scheme: display.vesa or display.virtio-gpu)
vesad / virtio-gpud (display driver daemon)
↓ (scheme: memory + irq)
Hardware (framebuffer / VirtIO GPU)
```
Rendering is software-only via LLVMpipe (Mesa CPU OpenGL emulation).
No GPU acceleration pipeline exists yet.
## 5. relibc — C Library
relibc is a **POSIX-compatible C library written in Rust**. Provides:
- Standard C library functions
- POSIX syscalls (section 2 + 3)
- Linux/BSD extensions
Targets: Redox (via `redox-rt`), Linux (direct syscalls).
Architectures: i586, x86_64, aarch64, riscv64gc.
### Known POSIX Gaps (blocking Wayland)
These are the specific missing features found in libwayland's `redox.patch`:
| Missing API | Used By | Status |
|-------------|---------|--------|
| `signalfd` / `SFD_CLOEXEC` | libwayland event loop | Not implemented |
| `timerfd` / `TFD_CLOEXEC` / `TFD_TIMER_ABSTIME` | libwayland timers | Not implemented |
| `eventfd` / `EFD_CLOEXEC` | libwayland server | Not implemented |
| `F_DUPFD_CLOEXEC` | libwayland fd management | Not implemented |
| `MSG_CMSG_CLOEXEC` | libwayland socket recv | Not implemented |
| `MSG_NOSIGNAL` | libwayland connection | Not implemented |
| `open_memstream` | libdrm, libwayland | Not implemented |
## 6. Build System (This Repository)
This repository is the **build system** — it orchestrates fetching, building, and packaging
components from ~100+ Git repositories into a bootable Redox image.
### Key Directories
| Directory | Purpose |
|-----------|---------|
| `config/` | Build configurations (desktop, server, wayland, x11, minimal) |
| `recipes/` | Package recipes (source + build instructions) |
| `recipes/core/` | Essential: kernel, bootloader, relibc, init |
| `recipes/gui/` | Orbital, orbterm, orbutils |
| `recipes/libs/` | Libraries: mesa, cairo, pango, SDL, etc. |
| `recipes/wip/` | Work-in-progress packages (wayland/, kde/, gnome/, etc.) |
| `mk/` | Makefile infrastructure |
| `src/` | Build system source (cookbook tool in Rust) |
### Config System
Configs are TOML files that include each other:
```
wayland.toml → desktop.toml → desktop-minimal.toml → minimal.toml → base.toml
```
Each config selects packages and overrides init scripts. For example, `wayland.toml`
overrides the orbital init to launch `cosmic-comp` instead of `orblogin`.
### Build Flow
```bash
make all
→ downloads cross-toolchain (Clang/LLVM for x86_64-unknown-redox)
→ fetches recipe sources (git/tar)
→ applies patches (redox.patch files)
→ builds each recipe (cargo, meson, cmake, make, custom)
→ stages into sysroot
→ creates RedoxFS image
→ produces harddrive.img / redox-live.iso
```
## 7. Existing Wayland/X11 Support
### X11 (Working)
Config: `config/x11.toml`
- X.org with dummy video driver inside Orbital
- GTK3, MATE desktop, Mesa EGL
- DRI3 enabled
- Software rendering only
### Wayland (Experimental, WIP)
Config: `config/wayland.toml`
- **21 Wayland recipes** in `recipes/wip/wayland/`
- **cosmic-comp**: partially working, performance issues, no keyboard input
- **smallvil** (Smithay): ported, basic compositor running
- **wlroots**: not compiled or tested
- **sway**: not compiled or tested
- **hyprland**: not compiled or tested
- **niri**: needs Smithay port
- **xwayland**: partially patched, needs wayland-client fixes
### Key Blockers for Wayland
1. **relibc POSIX gaps** (signalfd, timerfd, eventfd, open_memstream)
2. **No GPU acceleration** (only software rendering)
3. **No libinput** (requires evdev + udev)
4. **No DRM/KMS** (libdrm has all GPU drivers disabled)
5. **cosmic-comp**: missing keyboard input, performance issues

## Parallel Execution Plan
```
Week 1-4: M1 (relibc POSIX gaps)
Week 3-12: M2 (evdev input) ──── parallel ──── M3 (DRM/KMS)
Week 13-16: M4 (Wayland compositor = M2 + M3 + M1)
Week 13-24: M8 (Linux driver compat, parallel with M4-M6)
Week 17-24: M5 (Qt Foundation)
Week 25-32: M6 (KDE Frameworks)
Week 33-38: M7 (Plasma Desktop)
```
**Total to KDE Plasma**: ~38 weeks (~9 months) with 2 developers.
**Total to Linux driver compat**: ~24 weeks (~6 months) in parallel.
## Critical Path
```
M1 (POSIX) ──────────────────────────────────────┐
│
M3 (DRM/KMS) ─────────── M4 (Compositor) ── M5 (Qt) ── M6 (KDE) ── M7 (Plasma)
│ ↑ │
M2 (Input) ──────────────┘ M8 (Linux drivers, parallel)
```
**Shortest path to a desktop**: M1 → M2 → M3 (parallel) → M4 → M5 → M6 → M7
**Shortest path to GPU drivers**: M3 → M8 (can start as soon as `redox-driver-sys` exists)

# 03 — Wayland on Redox: Concrete Implementation Path
## Goal
Get a working Wayland compositor on Redox OS that can run KDE Plasma applications.
## Current State
- `config/wayland.toml` exists — launches `cosmic-comp` or `smallvil` via `orbital-wayland`
- 21 Wayland recipes in `recipes/wip/wayland/` — most untested
- `libwayland` 1.24.0 builds with `redox.patch` that stubs out 7 POSIX APIs
- `smallvil` (Smithay) runs as basic compositor, performance poor
- `cosmic-comp` builds but has no keyboard input (missing libinput)
- `libdrm` builds with all GPU drivers disabled
- Mesa uses OSMesa (software rendering only)
---
## Step 1: Fix relibc POSIX Gaps (1-2 weeks)
### What to implement
These are the 7 APIs that libwayland's `redox.patch` removes. Each must be added
to `relibc` (repo: https://gitlab.redox-os.org/redox-os/relibc).
#### 1.1 `signalfd` / `signalfd4`
**Files to create/modify in relibc:**
```
src/header/signal/mod.rs — add signalfd(), signalfd4()
src/header/signal/src.rs — add SFD_CLOEXEC, SFD_NONBLOCK constants
src/header/signal/types.rs — add signalfd_siginfo struct
src/platform/redox/mod.rs — wire to kernel event scheme or userspace signal handler
```
**Implementation approach:**
```rust
// src/header/signal/mod.rs
pub fn signalfd(fd: c_int, mask: *const sigset_t, flags: c_int) -> c_int {
// If fd == -1, create a new "signal FD" using event scheme
// Register signal mask with the signal handling infrastructure
// Return FD that becomes readable when signals arrive
// Map to Redox: use event: scheme + signal userspace handler
}
```
**Approximate effort**: ~200 lines of Rust.
#### 1.2 `timerfd`
**Files to create in relibc:**
```
src/header/sys_timerfd/mod.rs — NEW: timerfd_create(), timerfd_settime(), timerfd_gettime()
src/header/sys_timerfd/types.rs — NEW: itimerspec, TFD_CLOEXEC, TFD_NONBLOCK, TFD_TIMER_ABSTIME
src/platform/redox/mod.rs — wire to time: scheme
```
**Implementation approach:**
```rust
// src/header/sys_timerfd/mod.rs
pub fn timerfd_create(clockid: c_int, flags: c_int) -> c_int {
// Create a timer FD using Redox time: scheme
// Return FD that becomes readable when timer fires
// Read returns uint64_t count of expirations
}
pub fn timerfd_settime(fd: c_int, flags: c_int, new: *const itimerspec, old: *mut itimerspec) -> c_int {
// Arm/disarm timer
// Use time: scheme for absolute/relative timers
}
```
**Approximate effort**: ~300 lines of Rust.
#### 1.3 `eventfd`
**Files to create in relibc:**
```
src/header/sys_eventfd/mod.rs — NEW: eventfd(), eventfd_read(), eventfd_write()
src/header/sys_eventfd/types.rs — EFD_CLOEXEC, EFD_NONBLOCK, EFD_SEMAPHORE
```
**Implementation approach:**
```rust
// Simplest of the three — just an atomic counter accessed via read/write
pub fn eventfd(initval: c_uint, flags: c_int) -> c_int {
// Create a pipe-like FD backed by a shared atomic counter
// read() blocks until counter > 0, returns counter, resets to 0
// write() adds to counter
// Use Redox pipe: scheme internally
}
```
**Approximate effort**: ~100 lines of Rust.
#### 1.4 `F_DUPFD_CLOEXEC`
**File to modify in relibc:**
```
src/header/fcntl/mod.rs — add F_DUPFD_CLOEXEC constant (value 0x40 on Linux x86_64)
src/platform/redox/alloc.rs — handle F_DUPFD_CLOEXEC in fcntl()
```
```rust
// In fcntl handler:
pub const F_DUPFD_CLOEXEC: c_int = 0x406; // Linux value
// In fcntl() match:
F_DUPFD_CLOEXEC => {
let new_fd = syscall::dup(fd, None)?;
// Set CLOEXEC flag on new_fd
// Return new_fd
}
```
**Approximate effort**: ~20 lines.
#### 1.5 `MSG_CMSG_CLOEXEC` and `MSG_NOSIGNAL`
**Files to modify in relibc:**
```
src/header/sys_socket/mod.rs — add MSG_CMSG_CLOEXEC (0x40000000), MSG_NOSIGNAL (0x4000)
src/platform/redox/mod.rs — handle in recvmsg/sendmsg
```
`MSG_NOSIGNAL`: suppress SIGPIPE on broken connection. On Redox, SIGPIPE handling
is already userspace — just don't send the signal when this flag is set.
`MSG_CMSG_CLOEXEC`: set CLOEXEC on FDs received via SCM_RIGHTS. Apply the flag
when processing ancillary data in recvmsg.
**Approximate effort**: ~50 lines.
#### 1.6 `open_memstream`
**File to modify in relibc:**
```
src/header/stdio/mod.rs — add open_memstream()
src/header/stdio/src.rs — implementation
```
```rust
pub fn open_memstream(bufp: *mut *mut c_char, sizep: *mut usize) -> *mut FILE {
// Create a write-only stream that dynamically grows a buffer
// On close or flush, update *bufp and *sizep
// Can be implemented using a backing Vec<u8> and custom FILE vtable
}
```
**Approximate effort**: ~200 lines.
### Verification
After implementing all 7 APIs:
1. Rebuild relibc: `./target/release/repo cook recipes/core/relibc`
2. Rebuild libwayland **without** `redox.patch` — it should compile natively
3. Test: `wayland-rs_simple_window` runs without crashes
---
## Step 2: evdev Input Daemon (4-6 weeks)
### Architecture
```
┌──────────────────┐ ┌──────────────────────┐ ┌──────────────┐
│ libinput │────→│ /dev/input/eventX │────→│ evdevd │
│ (ported) │ │ (character devices) │ │ (daemon) │
└──────────────────┘ └──────────────────────┘ └──────┬───────┘
│
reads Redox schemes:
input:, scheme:irq
```
### What to build
**New daemon: `evdevd`** (userspace, like all Redox drivers)
Create as a new recipe: `recipes/core/evdevd/`
**Source structure:**
```
evdevd/
├── Cargo.toml
├── src/
│ ├── main.rs — daemon entry, scheme registration
│ ├── scheme.rs — implements "evdev" scheme
│ ├── device.rs — translates Redox events to input_event
│ └── ioctl.rs — handles EVIOCG* ioctls
```
**Key implementation:**
```rust
// src/main.rs
fn main() {
// 1. Open existing Redox input sources
let keyboard = File::open("scheme:input/keyboard")?;
let mouse = File::open("scheme:input/mouse")?;
// 2. Create /dev/input symlinks (pointing to our scheme)
// /dev/input/event0 → /scheme/evdev/keyboard
// /dev/input/event1 → /scheme/evdev/mouse
// 3. Register evdev scheme
let scheme = File::create(":evdev")?;
// 4. Event loop: read from Redox input schemes, translate, write to evdev clients
loop {
let redox_event = read_redox_event(&keyboard)?;
let evdev_event = translate_to_input_event(redox_event);
// Deliver to subscribed clients
}
}
```
```rust
// src/ioctl.rs — implement evdev ioctls
fn handle_ioctl(fd: usize, request: usize, arg: usize) -> Result<usize> {
match request {
EVIOCGNAME => { /* write device name string to arg */ },
EVIOCGBIT => { /* write supported event types bitmap to arg */ },
EVIOCGABS => { /* write absinfo struct for absolute axes */ },
EVIOCGRAB => { /* grab/exclusive access to device */ },
EVIOCGPROP => { /* write device properties bitmap */ },
_ => Err(syscall::Error::new(syscall::EINVAL)),
}
}
```
**Also needed: udev shim**
Create `recipes/wip/wayland/udev-shim/` — a minimal udev implementation that:
- Enumerates `/dev/input/event*` devices
- Emits "add"/"remove" events via netlink-compatible socket
- Provides `udev_device_get_property_value()` for `ID_INPUT_*` properties
libinput needs this for hotplug. A minimal shim is ~500 lines of Rust.
**Then port libinput:**
Modify `recipes/wip/wayland/libinput/` (currently missing — create it):
```toml
[source]
tar = "https://gitlab.freedesktop.org/wayland/libinput/-/archive/1.27.0/libinput-1.27.0.tar.gz"
patches = ["redox.patch"]
[build]
template = "meson"
dependencies = [
"evdevd",
"libffi",
"libwayland",
"udev-shim",
"mtdev", # touchpad multi-touch
"libevdev", # evdev wrapper library
]
mesonflags = [
"-Ddocumentation=false",
"-Dtests=false",
"-Ddebug-gui=false",
]
```
### Verification
1. Build and run `evdevd`
2. `cat /dev/input/event0` shows keyboard events
3. Build libinput against evdevd
4. `libinput list-devices` shows keyboard and mouse
---
## Step 3: DRM/KMS Scheme (8-12 weeks)
### Architecture
```
┌──────────────┐ ┌───────────────────┐ ┌────────────────┐
│ libdrm │───→│ scheme:drm/card0 │───→│ drmd (daemon) │
│ (ported) │ │ DRM ioctls via │ │ GPU driver │
│ │ │ scheme protocol │ │ userspace │
└──────────────┘ └───────────────────┘ └───────┬────────┘
│
scheme:memory + scheme:irq
│
Hardware (GPU)
```
### What to build
**New daemon: `drmd`** (DRM daemon — starts with Intel support)
Create as: `recipes/core/drmd/`
**Source structure:**
```
drmd/
├── Cargo.toml
├── src/
│ ├── main.rs — daemon entry, PCI enumeration
│ ├── scheme.rs — registers "drm" scheme
│ ├── kms/
│ │ ├── mod.rs — KMS object management
│ │ ├── crtc.rs — CRTC implementation
│ │ ├── connector.rs — connector (HDMI, DP, eDP)
│ │ ├── encoder.rs — encoder
│ │ ├── plane.rs — primary + cursor planes
│ │ └── framebuffer.rs — framebuffer allocation
│ ├── gem/
│ │ ├── mod.rs — GEM buffer management
│ │ └── dmabuf.rs — DMA-BUF export/import
│ └── drivers/
│ ├── mod.rs — driver trait
│ └── intel.rs — Intel GPU driver (modesetting)
```
**Core DRM scheme protocol:**
```rust
// src/scheme.rs
// DRM scheme implements the same ioctls as Linux /dev/dri/card0
// but via Redox scheme read/write/packet protocol
enum DrmRequest {
// Core
GetVersion,
GetCap { capability: u64 },
// KMS
ModeGetResources,
ModeGetConnector { connector_id: u32 },
ModeGetEncoder { encoder_id: u32 },
ModeGetCrtc { crtc_id: u32 },
ModeSetCrtc { crtc_id: u32, fb_id: u32, x: u32, y: u32, connectors: Vec<u32>, mode: ModeModeInfo },
ModePageFlip { crtc_id: u32, fb_id: u32, flags: u32, user_data: u64 },
ModeAtomicCommit { flags: u32, props: Vec<AtomicProp> },
// GEM
GemCreate { size: u64 },
GemClose { handle: u32 },
GemMmap { handle: u32 },
// Prime/DMA-BUF
PrimeHandleToFd { handle: u32, flags: u32 },
PrimeFdToHandle { fd: i32 },
}
```
**Intel driver (starting point):**
```rust
// src/drivers/intel.rs
// Based on public Intel GPU documentation:
// https://01.org/linuxgraphics/documentation/hardware-specification-prm
pub struct IntelDriver {
mmio: *mut u8, // Memory-mapped I/O registers (via scheme:memory)
gtt_size: usize, // Graphics Translation Table size
framebuffer: PhysAddr, // Current scanout buffer
}
impl IntelDriver {
pub fn new(pci_dev: &PciDev) -> Result<Self> {
// Map MMIO registers via scheme:memory/physical
let mmio = map_physical_memory(pci_dev.bar[0], pci_dev.bar_size[0])?;
// Initialize GTT (Graphics Translation Table)
// Set up display pipeline
Ok(Self { mmio, gtt_size, framebuffer })
}
pub fn modeset(&self, mode: &ModeInfo) -> Result<()> {
// 1. Allocate framebuffer in GTT
// 2. Configure pipe (timing, PLL)
// 3. Configure transcoder
// 4. Configure port (HDMI/DP)
// 5. Enable scanout from new framebuffer
Ok(())
}
pub fn page_flip(&self, crtc: u32, fb: PhysAddr) -> Result<()> {
// 1. Update GTT entry to point to new framebuffer
// 2. Trigger page flip on next VBlank
// 3. VBlank interrupt signals completion (via scheme:irq)
Ok(())
}
}
```
### Verification
1. `drmd` registers `scheme:drm/card0`
2. Port `modetest` (from libdrm tests) — shows connector info and modes
3. `modetest -M intel -s 0:1920x1080` sets a mode and shows test pattern
---
## Step 4: Working Wayland Compositor (4-6 weeks after Steps 1-3)
### Recommended: Smithay/smallvil first, then KWin
**Why Smithay first:**
- Pure Rust — no C++ toolchain issues
- Already has a Redox branch (`https://github.com/jackpot51/smithay`, branch `redox`)
- Smithay's input backend is pluggable — write a Redox-specific one
- Gets us a working compositor months before KWin is ported
**What to modify in Smithay:**
```
smithay/
├── src/backend/
│ ├── input/
│ │ └── redox.rs — NEW: Redox input backend (reads evdev scheme)
│ ├── drm/
│ │ └── redox.rs — NEW: Redox DRM backend (uses scheme:drm)
│ └── egl/
│ └── redox.rs — NEW: Redox EGL display (uses Mesa)
```
**Redox input backend:**
```rust
// src/backend/input/redox.rs
pub struct RedoxInputBackend {
devices: Vec<EvdevDevice>, // opened from /dev/input/eventX
}
impl InputBackend for RedoxInputBackend {
fn dispatch(&mut self) -> Vec<InputEvent> {
// Read from all evdev devices via evdevd
// Translate to Smithay's InternalEvent type
}
}
```
**Redox DRM backend:**
```rust
// src/backend/drm/redox.rs
pub struct RedoxDrmBackend {
drm_fd: File, // opened from /scheme/drm/card0
}
impl DrmBackend for RedoxDrmBackend {
fn create_surface(&self, size: Size) -> Surface {
// Create framebuffer via DRM GEM
// Set KMS mode via scheme:drm
}
fn page_flip(&self, surface: &Surface) -> Result<VBlank> {
// DRM page flip via scheme
}
}
```
### Recipe to add/modify
```toml
# recipes/wip/wayland/smallvil/recipe.toml (modify existing)
[source]
git = "https://github.com/jackpot51/smithay"
branch = "redox"
[build]
template = "cargo"
dependencies = [
"libffi",
"libwayland",
"libxkbcommon",
"mesa", # for EGL
"libdrm", # for DRM backend
"evdevd", # for input
"seatd", # for session management
]
cargopackages = ["smallvil"]
```
### Verification
1. `smallvil` launches with DRM backend — takes over display
2. Keyboard and mouse work via evdevd
3. `libcosmic-wayland_application` renders a window on the compositor
4. Screenshot shows the window
---
## Step 5: Enable cosmic-comp and Other Compositors
Once Steps 1-4 are done:
1. **cosmic-comp**: Uncomment libinput dependency in recipe, rebuild
2. **wlroots**: Build with libdrm + libinput + GBM
3. **sway**: Should work once wlroots builds
4. **KWin**: See `05-KDE-PLASMA-ON-REDOX.md` for the full path
---
## Fastest Path Summary
```
Week 1-2: Implement signalfd/timerfd/eventfd/etc in relibc
→ libwayland builds without patches
Week 3-8: Build evdevd (input daemon) + udev shim
→ libinput works
Week 9-20: Build drmd (DRM daemon) with Intel modesetting
→ libdrm works, modesetting functional
Week 21-26: Smithay Redox backends (input + DRM + EGL)
→ Working Wayland compositor with hardware display
Week 27+: Port Qt, KDE Frameworks, Plasma Shell
→ KDE Plasma desktop (see doc 05)
```
**Key insight**: Steps 2 (evdev) and 3 (DRM) can run in parallel.
With 2 developers, the Wayland compositor is achievable in ~6 months.

# 04 — Linux Driver Compatibility Layer: Concrete Implementation Path
## Goal
Enable running Linux GPU drivers (amdgpu, i915, nouveau) on Redox OS with minimal
changes to the driver source code, by providing a FreeBSD LinuxKPI-style compatibility shim.
## Why This Is Needed
Writing native Rust GPU drivers for every vendor is years of work. Linux has mature,
vendor-supported GPU drivers. A compatibility layer lets us port them with `#ifdef __redox__`
patches instead of full rewrites.
**Target drivers** (in priority order):
1. **i915** (Intel) — best documented, most relevant for laptops
2. **amdgpu** (AMD) — large market share, good open-source driver
3. **nouveau / nvk** (NVIDIA) — community driver, limited performance
4. **Skip**: NVIDIA proprietary (binary-only, impossible without full Linux kernel)
---
## Architecture
### Two-Mode Design
The compat layer operates in two modes:
**Mode A: C Driver Port** — Compile Linux C driver against our headers, run as userspace daemon
**Mode B: Rust Wrapper** — Rust crate provides idiomatic API, internally calls compat layer
Both modes share the same bottom layer: `redox-driver-sys`.
```

│ Mode A: C Driver Port │
│ Linux C driver (i915.ko source) │

├────────────────────────────────────────────────────────────┤
│ Mode B: Rust Wrapper │
│ Rust crate (redox-intel-gpu) using compat APIs │

└────────────────────────────────────────────────────────────┘
```
---
## Implementation: Crate and File Layout
### Crate 1: `redox-driver-sys` (Low-level Redox driver primitives)
**Repository**: New crate in the Redox ecosystem.
**Purpose**: Safe Rust wrappers around Redox's scheme-based hardware access.
```
redox-driver-sys/
├── Cargo.toml
├── src/
│ ├── lib.rs — Re-exports
│ ├── memory.rs — Physical memory mapping (scheme:memory)
│ ├── irq.rs — Interrupt handling (scheme:irq)
│ ├── pci.rs — PCI device access (scheme:pci / pcid)
│ ├── io.rs — Port I/O (iopl syscall)
│ └── dma.rs — DMA buffer management
```
**Key implementations:**
```rust
// src/memory.rs
pub fn map_physical(phys: u64, size: usize, flags: MapFlags) -> Result<*mut u8> {
// Open scheme:memory/physical
// Use fmap to map physical address range
// flags: WriteCombine, Uncacheable, WriteBack
let fd = File::open("scheme:memory/physical")?;
let ptr = syscall::fmap(fd.as_raw_fd(), &Map {
offset: phys,
size,
flags: flags.to_syscall_flags(),
})?;
Ok(ptr as *mut u8)
}
pub fn unmap_physical(ptr: *mut u8, size: usize) -> Result<()> {
syscall::funmap(ptr as usize, size)?;
Ok(())
}
```
```rust
// src/irq.rs
pub struct IrqHandle { fd: File }
impl IrqHandle {
pub fn request(irq_num: u32) -> Result<Self> {
// Open /scheme/irq/{irq_num}
// Read blocks until interrupt fires
let fd = File::open(&format!("scheme:irq/{}", irq_num))?;
Ok(Self { fd })
}
pub fn wait(&mut self) -> Result<()> {
let mut buf = [0u8; 8];
self.fd.read(&mut buf)?;
Ok(())
}
}
```
```rust
// src/pci.rs
pub struct PciDevice {
bus: u8, dev: u8, func: u8,
vendor_id: u16, device_id: u16,
bars: [u64; 6],
bar_sizes: [usize; 6],
irq: u32,
}
pub fn enumerate() -> Result<Vec<PciDevice>> {
// Read from pcid-spawner or scheme:pci
// Parse PCI configuration space for each device
// Filter to GPU devices (class 0x030000-0x0302xx)
}
```
### Crate 2: `linux-kpi` (Linux kernel API compatibility)
**Repository**: New crate. Installs C headers for use by Linux C drivers.
**Purpose**: Provides `linux/*.h` headers that translate Linux kernel APIs to `redox-driver-sys`.

// GFP flags — on Redox, these are no-ops (userspace allocation)
#define GFP_KERNEL 0
#define GFP_ATOMIC 1
#define GFP_DMA32 2
void *kmalloc(size_t size, unsigned int flags);
void *kzalloc(size_t size, unsigned int flags);

#[no_mangle]
pub extern "C" fn kzalloc(size: usize, _flags: u32) -> *mut u8 {

alloc_zeroed(layout)
}
}
#[no_mangle]
pub extern "C" fn kfree(ptr: *const u8) {

unsafe {
// Note: Linux kfree doesn't take size. We need a size-tracking allocator.

}
```
### Crate 3: `redox-drm` (DRM scheme implementation)

## Concrete Porting Example: Intel i915 Driver
### Step 1: Extract i915 from Linux kernel
```bash
# Clone Linux kernel
git clone --depth 1 https://github.com/torvalds/linux.git
# Extract relevant directories
tar cf intel-driver.tar linux/drivers/gpu/drm/i915/ \
linux/include/drm/ \
linux/include/linux/ \
linux/arch/x86/include/
```
### Step 2: Create recipe
```toml
# recipes/wip/drivers/i915/recipe.toml
[source]
tar = "intel-driver.tar"
[build]
template = "custom"
dependencies = [
"redox-driver-sys",
"linux-kpi",
"redox-drm",
]
script = """
DYNAMIC_INIT
# Build i915 driver as a shared library
# linked against linux-kpi and redox-driver-sys
export CFLAGS="-I${COOKBOOK_SYSROOT}/include/linux-kpi -D__redox__"
export LDFLAGS="-lredox_driver_sys -llinux_kpi -lredox_drm"
# Compile the driver source files
find drivers/gpu/drm/i915/ -name '*.c' | while read src; do
x86_64-unknown-redox-gcc -c $CFLAGS "$src" -o "${src%.c}.o" || true
done
# Link into a single shared library
x86_64-unknown-redox-gcc -shared -o i915_redox.so \
$(find drivers/gpu/drm/i915/ -name '*.o') \
$LDFLAGS
mkdir -p ${COOKBOOK_STAGE}/usr/lib/redox/drivers
cp i915_redox.so ${COOKBOOK_STAGE}/usr/lib/redox/drivers/
"""
```
### Step 3: Minimal patches needed
For i915 on Redox, these are the typical `#ifdef __redox__` changes:
```c
// Example patches (conceptual):
// 1. Replace Linux module init with daemon main()
#ifdef __redox__
int main(int argc, char **argv) {
return i915_driver_init();
}
#else
module_init(i915_init);
module_exit(i915_exit);
#endif
// 2. Replace kernel memory allocation
#ifdef __redox__
#include <linux/slab.h> // Our compat header
// kzalloc/kfree still work, but go to userspace allocator
#else
#include <linux/slab.h> // Real Linux
#endif
// 3. Replace PCI access
#ifdef __redox__
// Use redox-driver-sys PCI API instead of linux/pci.h internals
struct pci_dev *pdev = redox_pci_find_device(PCI_VENDOR_ID_INTEL, device_id);
#else
pdev = pci_get_device(PCI_VENDOR_ID_INTEL, device_id, NULL);
#endif
// 4. Replace MMIO mapping
#ifdef __redox__
void __iomem *regs = redox_ioremap(pci_resource_start(pdev, 0), pci_resource_len(pdev, 0));
#else
void __iomem *regs = ioremap(pci_resource_start(pdev, 0), pci_resource_len(pdev, 0));
#endif
```
### Step 4: Run as daemon
```bash
# In Redox init:
i915d # Registers scheme:drm/card0
```
---
## Concrete Porting Example: AMD amdgpu Driver
AMD's driver is larger and more complex than Intel's. The LinuxKPI approach is essential.
### Key challenges for amdgpu:
1. **Firmware loading**: amdgpu needs proprietary firmware blobs. Redox has no firmware
loading infrastructure yet. Need to implement:
```
scheme:firmware/amdgpu/ — firmware blob storage
request_firmware() — compat function that reads from scheme
```
2. **TTM memory manager**: amdgpu uses TTM (Translation Table Maps) for GPU memory.
Need to port TTM to use Redox's memory scheme:
```rust
// TTM → Redox mapping:
// ttm_tt → allocated pages via scheme:memory
// ttm_buffer_object → GemHandle in scheme:drm
// ttm_bo_move → page table updates via GPU MMIO
```
3. **Display Core (DC)**: AMD's display code is ~100K lines. Need to:
- Port DCN (Display Core Next) hardware programming
- Adapt to Redox's DRM scheme instead of Linux kernel DRM
- Keep most code unchanged, just redirect memory/register access
4. **Power management**: amdgpu uses Linux power management APIs. Need stubs:
```c
#ifdef __redox__
// No power management on Redox yet — always-on
#define pm_runtime_get_sync(dev) 0
#define pm_runtime_put_autosuspend(dev) 0
#define pm_runtime_allow(dev) 0
#endif
```
### Estimated patches for amdgpu: ~2000-3000 lines of `#ifdef __redox__`
---
## evdev Compatibility Layer
In addition to GPU drivers, we need an evdev compat layer for input:
### Crate: `redox-evdev`
```
redox-evdev/
├── src/
│ ├── lib.rs — evdev API for Rust
│ ├── c_headers/
│ │ └── linux/
│ │ └── input.h — struct input_event, EV_*, KEY_*, etc.
│ └── daemon/
│ └── main.rs — evdevd daemon (see doc 03)
```
The C header `linux/input.h` provides:
- `struct input_event` — identical to Linux
- `EV_KEY`, `EV_REL`, `EV_ABS` — event types
- `KEY_*`, `BTN_*`, `REL_*`, `ABS_*` — event codes
- `EVIOCG*` ioctl numbers — same values as Linux
The daemon reads from Redox input schemes and exposes `/dev/input/eventX` nodes.
---
## Implementation Priority and Timeline
| Phase | Component | Effort | Delivers |
|-------|-----------|--------|----------|
| 1 | `redox-driver-sys` crate | 2-3 weeks | Memory, IRQ, PCI, I/O primitives |
| 2 | Intel native driver (in `redox-drm`) | 6-8 weeks | First working GPU driver, modesetting |
| 3 | `linux-kpi` C headers (core subset) | 3-4 weeks | Memory, sync, PCI, workqueue headers |
| 4 | `linux-kpi` DRM headers | 2-3 weeks | DRM/KMS/GEM C API headers |
| 5 | i915 C driver port | 3-4 weeks | Proves LinuxKPI approach works |
| 6 | `linux-kpi` extended (TTM, firmware) | 4-6 weeks | Enables AMD driver |
| 7 | amdgpu C driver port | 6-8 weeks | AMD GPU support |
**Phase 1-2 is the critical path** — a native Rust Intel driver proves the architecture
and provides immediate value. Phases 3-7 can happen in parallel or later.
### With 2 developers:
- **Month 1-2**: redox-driver-sys + Intel native driver → first display output
- **Month 3-4**: linux-kpi core + DRM headers → i915 C port proof of concept
- **Month 5-8**: linux-kpi TTM + amdgpu port → AMD support
- **Total: 6-8 months** to support both Intel and AMD GPUs
### With 1 developer:
- **Month 1-3**: redox-driver-sys + Intel native driver
- **Month 4-6**: linux-kpi core + i915 port
- **Month 7-10**: amdgpu port
- **Total: 8-10 months**

# 05 — KDE Plasma on Redox: Concrete Implementation Path
## Goal
Run KDE Plasma 6 desktop environment on Redox OS, starting with a minimal viable
desktop and expanding to full Plasma.
## Prerequisites (from docs 03 and 04)
Before KDE work begins, these MUST be complete:
- [x] relibc POSIX gaps fixed (signalfd, timerfd, eventfd, etc.)
- [x] evdevd + libinput working
- [x] DRM/KMS scheme working (at least Intel modesetting)
- [x] Wayland compositor running (Smithay/smallvil)
- [x] Mesa EGL + software OpenGL (already ported)
## Three-Phase KDE Implementation
### Phase KDE-A: Qt Foundation (2-3 months)
**Goal**: A Qt application displays a window on the Redox Wayland compositor.
#### Step 1: Port `qtbase` (6-8 weeks)
**Create recipe**: `recipes/wip/qt/qtbase/recipe.toml`
```toml
[source]
tar = "https://download.qt.io/official_releases/qt/6.8/6.8.2/submodules/qtbase-everywhere-src-6.8.2.tar.xz"
patches = ["redox.patch"]
[build]
template = "custom"
dependencies = [
"libwayland",
"mesa", # EGL + OpenGL
"libdrm",
"libxkbcommon",
"zlib",
"openssl1",
"glib",
"pcre2",
"expat",
"fontconfig",
"freetype2",
]

-DQT_FEATURE_vulkan=OFF
cmake --build . -j${COOKBOOK_MAKE_JOBS}
cmake --install . --prefix ${COOKBOOK_STAGE}/usr
"""
```
**What `redox.patch` for qtbase needs to fix**:
1. **Platform detection**: Add `__redox__` as a POSIX-like platform
```
qtbase/src/corelib/global/qsystemdetection.h — add Redox detection
qtbase/src/corelib/io/qfilesystemengine_unix.cpp — Redox path handling
```
2. **Shared memory**: Qt uses `shm_open()` for Wayland buffers
```
qtbase/src/corelib/kernel/qsharedmemory.cpp — map to Redox shm scheme
```
3. **Process handling**: `fork`/`exec` differences
```
qtbase/src/corelib/io/qprocess_unix.cpp — already works (relibc POSIX)
```
4. **Network**: Qt uses BSD sockets — already work via relibc
```
qtbase/src/network/ — should compile with relibc sockets
```
**Estimated patch size**: ~500-800 lines for qtbase.
#### Step 2: Port `qtwayland` (1-2 weeks)
```toml
# recipes/wip/qt/qtwayland/recipe.toml
[source]
tar = "https://download.qt.io/official_releases/qt/6.8/6.8.2/submodules/qtwayland-everywhere-src-6.8.2.tar.xz"

-DCMAKE_INSTALL_PREFIX=/usr \
-DQT_BUILD_TESTS=OFF
cmake --build . -j${COOKBOOK_MAKE_JOBS}
cmake --install . --prefix ${COOKBOOK_STAGE}/usr
"""
```
#### Step 3: Port `qtdeclarative` (QML) (2-3 weeks)
```toml
# recipes/wip/qt/qtdeclarative/recipe.toml
[source]
tar = "https://download.qt.io/official_releases/qt/6.8/6.8.2/submodules/qtdeclarative-everywhere-src-6.8.2.tar.xz"
[build]
template = "custom"
dependencies = ["qtbase"]
script = """
# Same cmake pattern as qtwayland
"""
```
#### Step 4: Verify
```bash
# Build and run a simple Qt Wayland app:
cat > test.cpp << 'EOF'
#include <QApplication>
#include <QLabel>
int main(int argc, char *argv[]) {
QApplication app(argc, argv);
QLabel label("Hello from Qt on Redox!");
label.show();
return app.exec();
}
EOF
x86_64-unknown-redox-g++ test.cpp -o test-qt -I/usr/include/qt6 -lQt6Widgets -lQt6Gui -lQt6Core
# Run on compositor: WAYLAND_DISPLAY=wayland-0 ./test-qt
```
**Milestone**: Window with "Hello from Qt on Redox!" appears on Wayland compositor.
---
### Phase KDE-B: KDE Frameworks (2-3 months)
**Goal**: KDE applications can be built and run.
#### KDE Frameworks Tier 1 (2-3 weeks)
These have minimal dependencies — just Qt and CMake.
| Framework | Purpose | Estimated Patches |
|---|---|---|
| `extra-cmake-modules` | CMake modules for KDE | None — pure CMake |
| `kcoreaddons` | Core utilities | ~50 lines (process detection) |
| `kconfig` | Configuration system | ~30 lines (filesystem paths) |
| `kwidgetsaddons` | Extra Qt widgets | None — pure Qt |
| `kitemmodels` | Model/view classes | None — pure Qt |
| `kitemviews` | Item view classes | None — pure Qt |
| `kcodecs` | String encoding | None — pure Qt |
| `kguiaddons` | GUI utilities | None — pure Qt |
**Recipe pattern** (same for all Tier 1):
```toml
# recipes/wip/kde/kcoreaddons/recipe.toml
[source]
tar = "https://download.kde.org/stable/frameworks/6.10/kcoreaddons-6.10.0.tar.xz"
patches = ["redox.patch"]

-DBUILD_TESTING=OFF \
-DBUILD_QCH=OFF
cmake --build . -j${COOKBOOK_MAKE_JOBS}
cmake --install . --prefix ${COOKBOOK_STAGE}/usr
"""
```
#### KDE Frameworks Tier 2 (2-3 weeks)
| Framework | Dependencies | Notes |
|---|---|---|
| `ki18n` | `kcoreaddons`, gettext | Internationalization |
| `kauth` | `kcoreaddons` | PolicyKit stub needed |
| `kwindowsystem` | `qtbase` | Window management — needs Wayland backend |
| `kcrash` | `kcoreaddons` | Crash handler — may need signal adjustments |
| `karchive` | `qtbase`, zlib | Archive handling — should port cleanly |
| `kiconthemes` | `kwidgetsaddons`, `karchive` | Icon loading |
#### KDE Frameworks Tier 3 (3-4 weeks) — Plasma essentials only
| Framework | Purpose | Key for Plasma? |
|---|---|---|
| `kio` | File I/O abstraction | **Yes** — file dialogs, I/O slaves |
| `kservice` | Plugin/service management | **Yes** — app discovery |
| `kxmlgui` | GUI framework | **Yes** — menus, toolbars |
| `plasma-framework` | Plasma applets/containments | **Yes** — the desktop shell |
| `knotifications` | Desktop notifications | **Yes** — notification system |
| `kpackage` | Package/asset management | **Yes** — Plasma packages |
| `kconfigwidgets` | Configuration widgets | **Yes** — settings UI |
| `ktextwidgets` | Text editing widgets | Nice-to-have |
| `kbookmarks` | Bookmark management | Nice-to-have |
**Total frameworks needed for minimal Plasma: ~25**
**Estimated total patch effort for all frameworks: ~1500-2000 lines**
---
### Phase KDE-C: Plasma Desktop (2-3 months)
**Goal**: Full KDE Plasma desktop session.
#### Step 1: Port KWin (4-6 weeks)
KWin is the hardest component. It needs:
- DRM/KMS (for display control) → via our DRM scheme
- libinput (for input) → via our evdevd
- OpenGL ES 2.0+ (for effects) → via Mesa
- Wayland (for compositor protocol) → via libwayland
```toml
# recipes/wip/kde/kwin/recipe.toml
[source]
tar = "https://download.kde.org/stable/plasma/6.3.4/kwin-6.3.4.tar.xz"
patches = ["redox.patch"]
[build]
template = "custom"
dependencies = [
"qtbase", "qtwayland", "qtdeclarative",
"kcoreaddons", "kconfig", "kwindowsystem",
"knotifications", "kxmlgui", "plasma-framework",
"libwayland", "wayland-protocols",
"mesa", "libdrm", "libinput", "seatd",
"libxkbcommon",
]
script = """
DYNAMIC_INIT
mkdir -p build && cd build
cmake .. \
-DCMAKE_PREFIX_PATH=${COOKBOOK_SYSROOT}/usr \
-DCMAKE_INSTALL_PREFIX=/usr \
-DBUILD_TESTING=OFF \
-DKWIN_BUILD_SCREENLOCKING=OFF \
-DKWIN_BUILD_TABBOX=OFF \
-DKWIN_BUILD_EFFECTS=ON
cmake --build . -j${COOKBOOK_MAKE_JOBS}
cmake --install . --prefix ${COOKBOOK_STAGE}/usr
"""
```
**What `redox.patch` for KWin needs to fix**:
1. **DRM backend**: Replace `/dev/dri/card0` with `scheme:drm/card0`
```
src/backends/drm/drm_backend.cpp — open DRM scheme instead of device node
src/backends/drm/drm_output.cpp — use scheme ioctl equivalents
```
2. **libinput backend**: Should work via evdevd if `/dev/input/eventX` exists
```
src/backends/libinput/connection.cpp — may need path adjustments
```
3. **EGL/OpenGL**: KWin uses EGL + OpenGL ES
```
src/libkwineglbackend.cpp — Mesa EGL should work (already ported)
```
4. **Session management**: KWin expects logind. Need to stub or implement:
```
src/session.h/cpp — stub LogindIntegration, use seatd instead
```
5. **udev**: KWin uses udev for device enumeration
```
src/udev.h/cpp — redirect to our udev-shim
```
**Estimated KWin patches**: ~1000-1500 lines.
#### Step 2: Port `plasma-workspace` (2-3 weeks)
```toml
# recipes/wip/kde/plasma-workspace/recipe.toml
[source]
tar = "https://download.kde.org/stable/plasma/6.3.4/plasma-workspace-6.3.4.tar.xz"
[build]
template = "custom"
dependencies = [
# All KDE Frameworks above + kwin
"kwin", "plasma-framework", "kio", "kservice", "knotifications",
"kpackage", "kconfigwidgets",
"qtbase", "qtwayland", "qtdeclarative",
# System services
"dbus",
]
```
**Key component**: `plasmashell` — the desktop shell. Creates panels, desktop containment,
applet loader. Depends heavily on QML (qtdeclarative).
#### Step 3: Port `plasma-desktop` (1-2 weeks)
System settings, desktop containment configuration. Mostly Qt/QML.
#### Step 4: Create session config
```toml
# config/kde.toml (new file)
include = ["desktop.toml"]

## KDE Applications (Build on 19 WIP Recipes)
These are already partially ported in `recipes/wip/kde/`:
| App | Status | Notes |
|-----|--------|-------|
| kde-dolphin | WIP recipe exists | File manager — needs kio |
| kdenlive | WIP recipe exists | Video editor — needs MLT framework |
| krita | WIP recipe exists | Painting — needs Qt + OpenGL |
| kdevelop | WIP recipe exists | IDE — needs Qt + kio |
| okteta | WIP recipe exists | Hex editor |
| ktorrent | WIP recipe exists | BitTorrent client |
| ark | WIP recipe exists | Archive manager |
| kamoso | WIP recipe exists | Camera — needs PipeWire |
| kpatience | WIP recipe exists | Card game |
Once Qt + KDE Frameworks are ported, these apps should compile with minimal patches.
---
## System Integration Points
### D-Bus (Already Working)
D-Bus is ported and working in the X11 config. KDE uses D-Bus extensively.
Already configured in `config/x11.toml`.
### Audio: PulseAudio PipeWire Shim Needed
KDE expects PulseAudio or PipeWire for audio. Redox has its own `scheme:audio`.
**Option A**: Port PipeWire to Redox (large effort)
**Option B**: Write a PulseAudio compatibility shim that translates to Redox audio scheme
**Option C**: Use KDE without audio initially (just disable audio notifications)
### Service Management: D-Bus Service Files
KDE services register via D-Bus `.service` files. Redox init starts services.
Need a translation layer that:
1. Reads `/usr/share/dbus-1/services/*.service` files
2. Maps to Redox init scripts
3. Responds to D-Bus StartServiceByName calls
### Network: KDE NetworkManager integration
KDE uses NetworkManager for network configuration. Redox has `smolnetd`.
**Option A**: Port NetworkManager (massive effort, needs systemd)
**Option B**: Write a NetworkManager D-Bus shim that talks to smolnetd
**Option C**: Skip network configuration UI initially
---
## Timeline
| Phase | Duration | Milestone |
|-------|----------|-----------|
| Qt Foundation | 8-12 weeks | Qt app shows a window |
| KDE Frameworks | 8-12 weeks | KDE app (kate) runs |
| KWin + Plasma Shell | 6-8 weeks | KDE desktop visible |
| KDE Apps | 4-6 weeks | Dolphin, Konsole, Kate working |
| **Total** | **10-15 months** | Full KDE Plasma session |
**Critical insight**: The Qt Foundation phase is the highest-risk phase.
If Qt compilation hits unexpected relibc gaps, the entire KDE timeline shifts.
Mitigation: start Qt porting early, even before DRM/input is complete,
using software rendering and Orbital backend as a test environment.

### Install Rust and Cargo Tools
```bash
# Install Rust via rustup
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
source "$HOME/.cargo/env"
# Install required cargo tools
cargo install just cbindgen
```
## Configuration
### Native Build (No Container)
```bash
# In the redox-master directory:
echo 'PODMAN_BUILD?=0' > .config
```
### Podman Build (Containerized, Default)
```bash
# Default uses Podman — no configuration needed
# Ensure Podman is installed:
# Arch: sudo pacman -S podman
# Debian: sudo apt-get install podman
```
### Select Build Configuration
Available configs (in `config/`):
| Config | Description |
|---|---|
| `minimal` | Bare minimum bootable system |
| `server` | Server-oriented (no GUI) |
| `desktop-minimal` | Orbital + basic GUI apps |
| `desktop` | COSMIC apps + installer |
| `wayland` | Wayland compositor (experimental) |
| `x11` | X.org + MATE desktop |
| `demo` | Demo apps |
## Building
### Full Build (Desktop)
```bash
make all
```
This produces `build/x86_64/desktop/harddrive.img`.
### Build with Specific Config
```bash
# Using build.sh wrapper:
./build.sh -c wayland all # Wayland config
./build.sh -c server all # Server config
./build.sh -c x11 all # X11 config
./build.sh -a aarch64 -c desktop all # ARM64 build
```
### Build a Live ISO
```bash
make live
# Produces: build/x86_64/desktop/redox-live.iso
```
### Rebuild After Changes
```bash
make rebuild # Clean rebuild of filesystem image
```
## Running
### QEMU (Recommended)
```bash
# Desktop with Orbital GUI:
make qemu
# With more RAM:
make qemu QEMUFLAGS="-m 4G"
# Without GUI (serial console):
make qemu QEMUFLAGS="-nographic"
# With network (port forwarding):
make qemu QEMUFLAGS="-net nic -net user,hostfwd=tcp::8080-:80"
```
### VirtualBox
```bash
make virtualbox
```
### Live USB
```bash
# Write image to USB device (replace sdX with your device):
sudo dd if=build/x86_64/desktop/harddrive.img of=/dev/sdX bs=4M status=progress
```
## Building Specific Packages (Recipes)
### Build a Single Recipe
```bash
# Using the repo tool:
./target/release/repo cook recipes/libs/mesa
./target/release/repo cook recipes/gui/orbital
```
### Understanding Recipe Format
Each recipe is in `recipes/<category>/<name>/recipe.toml`:
```toml
[source]
git = "https://example.com/repo.git" # Git source
# tar = "https://example.com/source.tar.gz" # Or tar source
# branch = "main" # Git branch
# rev = "abc123" # Or specific commit
# patches = ["redox.patch"] # Patches to apply
[build]
template = "cargo" # Build template: cargo, meson, cmake, make, custom
dependencies = [
"dep1", # Other recipe names
"dep2",
]
# For custom builds:
script = """
DYNAMIC_INIT
cookbook_cargo --release
mkdir -p ${COOKBOOK_STAGE}/usr/bin
cp target/release/myapp ${COOKBOOK_STAGE}/usr/bin/
"""
```
### Build Templates
| Template | Description |
|---|---|
| `cargo` | Rust project (cargo build) |
| `meson` | Meson build system |
| `cmake` | CMake build system |
| `make` | GNU Make |
| `custom` | Custom script in `script` field |
## Key Build Variables
| Variable | Default | Description |
|---|---|---|
| `ARCH` | Host arch | Target architecture (x86_64, aarch64, i586, riscv64gc) |
| `CONFIG_NAME` | `desktop` | Build config name |
| `PODMAN_BUILD` | `1` | Use Podman container |
| `PREFIX_BINARY` | `1` | Use prebuilt toolchain (faster) |
| `REPO_BINARY` | `0` | Use prebuilt packages (faster, no compilation) |
| `REPO_NONSTOP` | `0` | Continue on build errors |
| `REPO_OFFLINE` | `0` | Don't update source repos |
### Environment Variables for Recipes
Inside recipe scripts, these are available:
| Variable | Description |
|---|---|
| `COOKBOOK_SOURCE` | Path to extracted source |
| `COOKBOOK_STAGE` | Path to staging directory (install target) |
| `COOKBOOK_SYSROOT` | Path to sysroot with deps |
| `COOKBOOK_TARGET` | Target triple (e.g., x86_64-unknown-redox) |
| `COOKBOOK_CARGO` | Cargo command with correct target |
| `COOKBOOK_MAKE` | Make command with correct flags |
## Troubleshooting
### Toolchain Download Fails
```bash
# Clean and retry:
rm -rf prefix/
make prefix # Re-download toolchain
```
### Build Errors in Specific Recipes
```bash
# Rebuild a specific recipe:
./target/release/repo cook recipes/<category>/<name>
# Skip failing recipes:
make all REPO_NONSTOP=1
```
### SELinux Issues (Fedora/RHEL)
```bash
make all USE_SELINUX=0
```
### Out of Disk Space
```bash
# Clean everything:
make clean
# Clean only fetched sources:
make distclean
```

# Redox OS Fork — Wayland, KDE & Linux Driver Compatibility
Technical documentation for forking Redox OS to include Wayland protocol support,
KDE Plasma desktop environment, and a Linux driver compatibility layer.
## Documents
| # | Document | Description |
|---|----------|-------------|
| 01 | [Architecture Overview](01-REDOX-ARCHITECTURE.md) | Redox OS internals: microkernel, scheme system, driver model, display stack |
| 02 | [Gap Analysis & Roadmap](02-GAP-ANALYSIS.md) | What's missing between current Redox and our Wayland/KDE/driver-compat goals |
| 03 | [Wayland on Redox](03-WAYLAND-ON-REDOX.md) | Deep-dive into Wayland protocol requirements and current porting status |
| 04 | [Linux Driver Compatibility Layer](04-LINUX-DRIVER-COMPAT.md) | Design for a FreeBSD LinuxKPI-style driver compatibility shim |
| 05 | [KDE Plasma on Redox](05-KDE-PLASMA-ON-REDOX.md) | Feasibility study and implementation plan for KDE Plasma |
| 06 | [Build System Setup](06-BUILD-SYSTEM-SETUP.md) | How to build Redox from this repository |
## Current State Summary (as of Redox 0.9.0)
- **Display server**: Orbital (custom, scheme-based) — works
- **Wayland**: Experimental, WIP. Smallvil (Smithay) and cosmic-comp partially working.
libwayland patched with shimmed-out `signalfd`, `timerfd`, `eventfd`.
- **X11**: Working via X.org dummy driver inside Orbital.
- **Mesa**: Software-rendered only (LLVMpipe/OSMesa). No GPU acceleration.
- **GPU drivers**: VESA framebuffer + VirtIO GPU only. Experimental Intel modesetting.
- **KDE**: 19 app recipes in WIP, no KDE Plasma infrastructure.
- **Linux driver compat**: None. Redox explicitly chose source-level porting over binary compat.
## Quick Start
```bash
# 1. Install dependencies (Arch/Manjaro)
sudo pacman -S --needed --noconfirm gdb meson nasm patchelf python-mako \
doxygen expat file fuse3 gmp libjpeg-turbo libpng po4a scons \

source "$HOME/.cargo/env"
cargo install just cbindgen
# 3. Configure for native build (no Podman)
echo 'PODMAN_BUILD?=0' > .config
# 4. Build (downloads cross-toolchain, then compiles)
make all
# 5. Run in QEMU
make qemu
```

# RED BEAR OS — DERIVATIVE OF REDOX OS
This directory contains ALL custom work on top of mainline Redox. When mainline Redox
updates (`git pull` on the build system repo), this directory is untouched.
## DESIGN PRINCIPLE
Red Bear OS relates to Redox OS in the same way Ubuntu relates to Debian:
- We track Redox OS as upstream, merging changes regularly
- We add custom packages, drivers, configs, and branding on top
- The `local/` directory is our overlay — untouched by upstream updates
- First-class configs use `redbear-*` naming (not `my-*`, which is gitignored)
Build flow:
```
make all CONFIG_NAME=redbear-desktop
→ mk/config.mk resolves to config/redbear-desktop.toml
→ Config includes desktop.toml (mainline) + Red Bear packages
→ repo cook builds all packages including our custom ones
→ mk/disk.mk creates harddrive.img with Red Bear branding
```
Update flow:
```
./local/scripts/sync-upstream.sh # Rebase onto upstream Redox + verify symlinks
make all CONFIG_NAME=redbear-full # Rebuild with latest
```
## TRACKING UPSTREAM (SYNC WITH REDOX OS)
Red Bear OS tracks the Redox OS build system as upstream. The `local/` directory
survives upstream updates untouched.
```bash
# Automated sync (preferred):
./local/scripts/sync-upstream.sh # Fetch + rebase + check patches
./local/scripts/sync-upstream.sh --dry-run # Preview conflicts before rebasing
./local/scripts/sync-upstream.sh --no-merge # Only check for patch conflicts
# Manual sync:
git remote add upstream-redox https://github.com/redox-os/redox.git # First time only
git fetch upstream-redox master
git rebase upstream-redox/master
# If rebase fails (nuclear option):
git rebase --abort
git reset --hard upstream-redox/master
./local/scripts/apply-patches.sh --force # Rebuild RBOS changes from patch files
# After sync:
cargo build --release # Rebuild cookbook
make all CONFIG_NAME=redbear-full # Rebuild OS
```

## HOW TO BUILD RED BEAR OS
```bash
# Full desktop with GPU drivers + branding
./local/scripts/build-redbear.sh redbear-desktop
# Minimal server variant
./local/scripts/build-redbear.sh redbear-minimal
# Live ISO
./local/scripts/build-redbear.sh redbear-live && make live CONFIG_NAME=redbear-live
# Or manually:
make all CONFIG_NAME=redbear-desktop
# Single custom recipe:
./target/release/repo cook local/recipes/branding/redbear-release
./target/release/repo cook local/recipes/system/redbear-meta
./target/release/repo cook local/recipes/core/ext4d
```
## TRACKING MAINLINE CHANGES
When mainline updates affect our work:
| Component | What to check | Where |
|-----------|---------------|-------|
| Kernel | ACPI, scheme, memory API changes | `recipes/core/kernel/source/src/` |
| relibc | New POSIX functions added upstream | `recipes/core/relibc/source/src/header/` |
| Base drivers | Driver API changes | `recipes/core/base/source/drivers/` |
| libdrm | DRM API updates | `recipes/wip/x11/libdrm/` or `recipes/libs/` |
| Mesa | OpenGL/Vulkan backend changes | `recipes/libs/mesa/` |
| Build system | Makefile/config changes | `mk/`, `src/` |
| rsext4 | ext4 crate API changes | `local/recipes/core/ext4d/source/` Cargo.toml |
| Installer | ext4 dispatch, filesystem selection | `local/patches/installer/redox.patch` |
## FILESYSTEMS
Red Bear OS supports two filesystems:
| Filesystem | Implementation | Package | Status |

### ext4 Workspace (`local/recipes/core/ext4d/source/`)
```
ext4d/source/
├── Cargo.toml ← Workspace: ext4-blockdev, ext4d, ext4-mkfs
├── ext4-blockdev/ ← BlockDevice trait impls for rsext4
│ ├── Cargo.toml ← Features: default=["redox"], redox=[libredox,syscall]
│ └── src/
│ ├── lib.rs ← Re-exports: FileDisk, RedoxDisk, Ext4Error, Ext4Result
│ ├── file_disk.rs ← FileDisk: std::fs backed, builds on host Linux + Redox
│ └── redox_disk.rs ← RedoxDisk: syscall/libredox backed, Redox-only (feature-gated)

│ ├── Cargo.toml ← Features: default=["redox"], redox deps
│ └── src/
│ ├── main.rs ← Daemon: fork, SIGTERM, scheme registration
│ ├── mount.rs ← Scheme event loop (redox_scheme::SchemeSync)
│ ├── scheme.rs ← Full ext4 FSScheme: open, read, write, mkdir, unlink, stat...
│ └── handle.rs ← FileHandle, DirectoryHandle, Handle types
└── ext4-mkfs/ ← ext4 mkfs tool (host-side utility)
├── Cargo.toml
└── src/main.rs ← Creates ext4 images via FileDisk + rsext4::mkfs
```
**Architecture**:
- `ext4d` is a Redox scheme daemon — it serves ext4 filesystems via `scheme:ext4d`
- Uses `rsext4` crate (pure Rust ext4 implementation) for all filesystem operations
- `FileDisk` allows building/testing on the Linux host machine
- `RedoxDisk` uses `libredox` + `redox_syscall` for actual Redox bare-metal I/O
- Both impls are behind the `redox` feature flag — `--no-default-features` gives Linux-only
**Recipe**: Symlinked into mainline search path:
```
recipes/core/ext4d → local/recipes/core/ext4d
```
**Config**: ext4d is included in `config/desktop.toml` (mainline), which `redbear-desktop.toml` inherits.
**Dependencies** (from workspace Cargo.toml):
- `rsext4 = "0.3"` — Pure Rust ext4 filesystem implementation
- `redox_syscall = "0.7.3"` — Redox syscall wrappers (scheme, data types, flags)
- `redox-scheme = "0.11.0"` — Scheme server framework
- `libredox = "0.1.13"` — High-level Redox syscalls (open, read, write, fstat)
- `redox-path = "0.3.0"` — Redox path utilities
### Installer ext4 Integration (`local/patches/installer/redox.patch`)
The mainline installer is patched to support ext4 as an install target filesystem:
- `GeneralConfig.filesystem: Option<String>` — TOML field, accepts `"redoxfs"` (default) or `"ext4"`
- `FilesystemType` enum — dispatch tag used by `install_inner`
- `with_whole_disk_ext4()` — GPT partition layout + ext4 mkfs + file sync (mirrors `with_whole_disk`)
- `Ext4SliceDisk<T>` — adapts `DiskWrapper` to rsext4's `BlockDevice` trait
- `sync_host_dir_to_ext4()` — copies staged sysroot files into ext4 filesystem
- CLI flag: `--filesystem ext4` or `--filesystem redoxfs`
Usage in config TOML:
```toml
[general]
filesystem = "ext4" # "redoxfs" is default
filesystem_size = 10240 # MB
```
## BRANDING ASSETS
Red Bear OS visual identity files live in `local/Assets/`.
```
local/Assets/
└── images/
├── Red Bear OS icon.png ← App icon / logo (1254x1254px)
│ Red bear head, dark background, red border
│ Use: desktop icon, bootloader logo, about dialog
└── Red Bear OS loading background.png ← Boot / loading screen (1536x1024px)
Cinematic red bear with forest silhouette
Use: bootloader splash, login screen background
```
**Integration points** (future):
| Asset | Target | How |
|-------|--------|-----|
| icon.png | Bootloader logo | Convert to BMP, embed via bootloader config |
| icon.png | Desktop icon | Install to `/usr/share/icons/hicolor/` via redbear-release recipe |
| icon.png | About dialog | COSMIC desktop reads from icon theme |
| loading background.png | Boot splash | Convert to framebuffer-compatible format, display before orbital starts |
| loading background.png | Login screen | Set as orblogin/orbital background |
**Current status**: Assets are committed to git. Not yet integrated into the build — requires bootloader and display server changes (Phase 2+).
## ANTI-PATTERNS
- **DO NOT** edit files under mainline `recipes/` directly — put patches in `local/patches/`
- **DO NOT** commit firmware blobs to git — use `local/scripts/fetch-firmware.sh`
- **DO NOT** modify `mk/` or `src/` directly — extend via `local/scripts/`
- **DO NOT** assume mainline recipe names won't conflict — prefix custom ones (e.g., `redox-`)
- **DO NOT** use `my-*` naming for configs that should be tracked in git — use `redbear-*` instead
- **DO NOT** edit config/base.toml directly — our configs include it and override via TOML merge
- **DO NOT** forget to run sync-upstream.sh before major builds — stale upstream causes build failures

# ACPI Fixes — P0 Phase Tracker
Status of ACPI fixes for AMD bare metal boot. Cross-referenced with
`HARDWARE.md` crash reports and kernel/acpid source TODOs.
## Crash Reports
| Hardware | Symptom | Root Cause | Status |
|----------|---------|------------|--------|
| Framework Laptop 16 (AMD 7040) | Crash on boot | Unimplemented ACPI function (jackpot51/acpi#3) | Under investigation |
| Lenovo ThinkCentre M83 | `Aml(NoCurrentOp)` panic at acpid acpi.rs:256 | AML interpreter encounters unsupported opcode | Under investigation |
| HP Compaq nc6120 | Crash after `kernel::acpi` prints APIC info | Unknown — may be ACPI or APIC init | Under investigation |
## Known Missing ACPI Table Parsers
| Table | Location | Status | Impact |
|-------|----------|--------|--------|
| DSDT (Differentiated System Description Table) | Parsed by `acpi` crate AML interpreter | Working | Platform-specific device config via AML bytecode |
| SSDT (Secondary System Description Table) | Parsed by `acpi` crate AML interpreter | Working | Secondary AML tables (hotplug, etc.) |
| FACP/FADT | Partially parsed in acpid | Partial | PM registers, reset register, sleep states |
| IVRS (AMD-Vi IOMMU) | ✅ Implemented in acpid | P2+ | AMD IOMMU for device passthrough |
| MCFG (PCI Express config space) | ✅ Implemented in acpid | P1 | PCIe extended config space access |
| DBG2 (Debug port) | Not implemented | Low | Serial debug port discovery |
| BGRT (Boot graphics) | Not implemented | Low | Boot logo preservation |
| FPDT (Firmware perf data) | Not implemented | Low | Boot performance metrics |
## Implemented ACPI Tables
| Table | Kernel | Userspace (acpid) | Notes |
|-------|--------|-------------------|-------|
| RSDP | `acpi/rsdp.rs` | N/A | Signature + checksum validated ✅ |
| RSDT/XSDT | `acpi/rsdt.rs`, `acpi/xsdt.rs` | N/A | Root table pointer iteration |
| MADT (APIC) | `acpi/madt/` | N/A | xAPIC + x2APIC (type 0x9) |

| DMAR (Intel VT-d) | N/A | `acpi/dmar/` | Iterator bug fixed, re-enabled |
| FADT | N/A | `acpi.rs` | Partial parse |
| SPCR | `acpi/spcr.rs` | N/A | ARM64 serial console |
| GTDT | `acpi/gtdt.rs` | N/A | ARM64 timers |
## Kernel ACPI TODOs
From `recipes/core/kernel/source/src/acpi/`:
| File | Line | TODO | Priority |
|------|------|------|----------|

## ACPID (Userspace) TODOs — UPSTREAM, NOT AMD-FIRST P0/P1
These are pre-existing upstream acpid issues. They are NOT part of the
AMD-first P0/P1 scope. They exist in mainline Redox acpid and affect all
platforms, not just AMD.

# AMD-FIRST REDOX OS — MASTER INTEGRATION PLAN
**Target**: Modern AMD64 bare metal machine with AMD GPU (RDNA2/RDNA3)
**Secondary**: Intel GPU machines
**Date**: 2026-04-11
## CRITICAL FINDINGS
### amdgpu is 18x larger than Intel i915
| Driver | Lines of Code | Complexity |
|--------|--------------|------------|
| amdgpu (AMD) | **6,048,151** | Largest driver in Linux kernel |
| i915 (Intel) | ~341,000 | Well-documented, simpler |
| nouveau (NVIDIA) | ~400,000 | Community driver |
**Implication**: AMD-first is HARDER but has larger market impact. We MUST use
the LinuxKPI compatibility approach — a clean Rust rewrite would take 5+ years.
### AMD Bare Metal Status on Redox
| Component | Status | Detail |
|-----------|--------|--------|
| UEFI boot | ✅ Works | x86_64 UEFI bootloader functional |
| AMD CPUs | ✅ Works | AMD 32/64-bit supported, Ryzen Threadripper verified |
| ACPI | ⚠️ Incomplete | Framework Laptop 16 crashes on unimplemented ACPI function |
| x2APIC | ✅ Works | Auto-detected via CPUID, APIC/SMP functional |
| HPET | ✅ Works | Timer initialized from ACPI |
| IOMMU | ❌ Missing | No VT-d or AMD-Vi support |
| AMD GPU | ❌ Missing | Only VESA/GOP framebuffer, no acceleration |
| Wi-Fi/BT | ❌ Missing | No wireless support |
| USB | ⚠️ Variable | Some USB controllers work, others don't |
### Known AMD-Specific Issues
1. **Framework Laptop 16 (AMD Ryzen 7040)**: CRASHES — unimplemented ACPI function (jackpot51/acpi#3)
2. **ASUS PRIME B350M-E**: Partial PS/2 keyboard, mouse broken
3. **Zen3+ page alignment**: Potential memory corruption with 16k-aligned pages
4. **I2C on AMD platforms**: Touchpad may fail
---
## PHASE 0: BARE METAL BOOT ON AMD (4-6 weeks)
Before any GPU or desktop work, Redox must boot reliably on modern AMD hardware.
### P0-1: Fix ACPI for AMD
**Problem**: Framework AMD Ryzen 7040 crashes. ACPI is incomplete.
**What to do**:
- Identify which ACPI function is unimplemented (see jackpot51/acpi#3)
- Implement missing ACPI table parsers (FACP, DSDT, SSDT)
- Test on: Framework 16, ASUS B350M-E, any modern AMD board
**Where**:
- Kernel: `recipes/core/kernel/source/src/acpi/`
- acpid: `recipes/core/base/source/drivers/acpid/`
- Patches: `local/patches/kernel/`
### P0-2: AMD-Specific Boot Hardening
**What to do**:
- Fix CPUID validation (FIXME in cpuid.rs)
- Fix Zen3+ page alignment issue (16k-aligned page smashing)
- Ensure trampoline page permissions are correct
- Validate memory map parsing on AMD systems with >4GB
**Where**: `recipes/core/kernel/source/src/arch/x86_64/`
### P0-3: Hardware Testing Matrix
**Required test hardware**:
- AMD Ryzen desktop (B550/X570 motherboard)
- AMD Ryzen laptop (Framework 16 or similar)
- AMD APU system (Ryzen 5xxxG series)
**Test procedure**: Write to `local/scripts/test-baremetal.sh`
---
## PHASE 1: DRIVER INFRASTRUCTURE (8-12 weeks)
### P1-1: redox-driver-sys Crate
**Purpose**: Safe Rust wrappers around Redox scheme-based hardware access.
```
local/recipes/drivers/redox-driver-sys/
├── Cargo.toml
├── src/
│ ├── lib.rs # Re-exports
│ ├── memory.rs # Physical memory mapping (scheme:memory)
│ ├── irq.rs # Interrupt handling (scheme:irq)
│ ├── pci.rs # PCI device access (scheme:pci / pcid)
│ ├── io.rs # Port I/O (iopl syscall)
│ └── dma.rs # DMA buffer management
```
**API design**: See `docs/04-LINUX-DRIVER-COMPAT.md` §Crate 1.
### P1-2: Firmware Loading Infrastructure
**Purpose**: Load AMD GPU firmware blobs from filesystem.
```
local/recipes/system/firmware-loader/
├── Cargo.toml
├── src/
│ ├── main.rs # Daemon: registers scheme:firmware
│ ├── scheme.rs # "firmware" scheme handler
│ └── blob.rs # Firmware blob management
```
**Firmware blobs needed for amdgpu** (from linux-firmware):
| Block | Purpose | File Pattern |
|-------|---------|-------------|
| PSP | Security processor | `psp_*_sos.bin`, `psp_*_ta.bin` |
| GC | Graphics/shader engine | `gc_*_me.bin`, `gc_*_pfp.bin`, `gc_*_ce.bin` |
| SDMA | DMA engine | `sdma_*_bin.bin` |
| VCN | Video encode/decode | `vcn_*_bin.bin` |
| SMC | Power management | `smu_*_bin.bin` |
| DMCUB | Display controller | `dcn_*_dmcub.bin` |
**Storage**: `local/firmware/amdgpu/` (fetched via `local/scripts/fetch-firmware.sh`)
### P1-3: linux-kpi Compatibility Headers
**Purpose**: C headers translating Linux kernel APIs → redox-driver-sys Rust calls.
```
local/recipes/drivers/linux-kpi/
├── Cargo.toml
├── src/
│ ├── lib.rs
│ ├── c_headers/linux/
│ │ ├── slab.h # → malloc/kfree
│ │ ├── mutex.h # → pthread mutex
│ │ ├── spinlock.h # → atomic lock
│ │ ├── pci.h # → redox-driver-sys::pci
│ │ ├── io.h # → port I/O
│ │ ├── irq.h # → redox-driver-sys::irq
│ │ ├── device.h # → struct device wrapper
│ │ ├── workqueue.h # → thread pool
│ │ ├── dma-mapping.h # → bus DMA
│ │ └── firmware.h # → firmware_loader scheme
│ ├── c_headers/drm/
│ │ ├── drm.h
│ │ ├── drm_crtc.h
│ │ ├── drm_gem.h
│ │ └── drm_ioctl.h
│ └── rust_impl/
│ ├── memory.rs # kmalloc, kzalloc, kfree
│ ├── sync.rs # mutex, spinlock, completion
│ ├── pci.rs # pci_register_driver
│ ├── firmware.rs # request_firmware
│ └── drm_shim.rs # DRM core → scheme:drm
```
---
## PHASE 2: AMD GPU DISPLAY OUTPUT (12-16 weeks)
### P2-1: redox-drm Daemon
**Purpose**: DRM scheme daemon — registers `scheme:drm/card0`.
```
local/recipes/gpu/redox-drm/
├── Cargo.toml
├── src/
│ ├── main.rs # Daemon entry, PCI enumeration for AMD GPUs
│ ├── scheme.rs # Registers "drm" scheme
│ ├── kms/ # KMS core
│ │ ├── crtc.rs # CRTC state machine
│ │ ├── connector.rs # Hotplug, EDID
│ │ ├── encoder.rs # Encoder management
│ │ └── plane.rs # Primary/cursor planes
│ ├── gem.rs # GEM buffer objects
│ ├── dmabuf.rs # DMA-BUF export/import
│ └── drivers/
│ ├── mod.rs # trait GpuDriver
│ └── amd/
│ ├── mod.rs # AMD driver entry
│ ├── display.rs # Display Core (DC) port
│ ├── gtt.rs # Graphics Translation Table
│ └── ring.rs # Command ring buffer
```
### P2-2: AMD Display Core Port (Mode A — C port)
**The critical decision**: amdgpu's display code (AMD DC) is ~1.5M lines. We port
ONLY the display/modesetting portion first, using linux-kpi headers.
**Approach**:
1. Extract `drivers/gpu/drm/amd/display/` from Linux kernel
2. Compile against linux-kpi headers with `-D__redox__`
3. Run as userspace daemon under redox-drm
4. Start with basic modesetting (no acceleration)
**Estimated patches**: ~3000-5000 lines of `#ifdef __redox__`
### P2-3: Firmware Loading for AMD
**Sequence on boot**:
```
1. pcid detects AMD GPU (vendor 0x1002)
2. pcid-spawner launches redox-drm with PCI device info
3. redox-drm maps MMIO registers via scheme:memory
4. redox-drm loads PSP firmware via scheme:firmware
5. PSP firmware loads GC, SDMA, SMC, DMCUB sub-firmwares
6. AMD DC initializes display pipeline
7. scheme:drm/card0 registered
8. modetest -M amd shows display modes
```
### Verification (Phase 2 complete when):
- `scheme:drm/card0` exists
- `modetest -M amd` shows connector info and modes
- `modetest -M amd -s 0:1920x1080` sets mode and shows test pattern
- Works on real AMD hardware (not just QEMU)
---
## PHASE 3: INPUT + POSIX (4-8 weeks, parallel with Phase 2)
### P3-1: relibc POSIX Gaps (2-4 weeks)
7 APIs needed by libwayland. Same as before regardless of GPU vendor.
| API | Effort | File to create/modify |
|-----|--------|----------------------|
| signalfd/signalfd4 | ~200 lines | `relibc/src/header/signal/` |
| timerfd_create/settime/gettime | ~300 lines | `relibc/src/header/sys_timerfd/` (NEW) |

| MSG_CMSG_CLOEXEC, MSG_NOSIGNAL | ~50 lines | `relibc/src/header/sys_socket/` |
| open_memstream | ~200 lines | `relibc/src/header/stdio/` |
**Patches go in**: `local/patches/relibc/`
### P3-2: evdevd Input Daemon (4-6 weeks)
Same as before. GPU vendor doesn't affect input path.
```
local/recipes/system/evdevd/
├── src/
│ ├── main.rs # Read Redox input schemes, expose /dev/input/eventX
│ ├── scheme.rs # "evdev" scheme
│ ├── device.rs # Translate Redox events → input_event
│ └── ioctl.rs # EVIOCG* ioctls
```
---
## PHASE 4: WAYLAND COMPOSITOR (4-6 weeks after P2+P3)
### P4-1: Smithay Redox Backends
```
smithay/src/backend/
├── input/redox.rs # Input backend (reads evdev via evdevd)
├── drm/redox.rs # DRM backend (uses scheme:drm)
└── egl/redox.rs # EGL display (uses Mesa)
```
### P4-2: libdrm AMD Backend
Currently libdrm has `-Damdgpu=disabled`. Enable it once redox-drm exists.
**Patches**: `local/patches/libdrm/`
---
## PHASE 5: AMD GPU ACCELERATION (16-24 weeks, parallel with P4)
### P5-1: Full amdgpu Port via LinuxKPI
This is the big one. Port the full amdgpu driver using linux-kpi headers.
**Scope**: ~666k lines of actual C code (excluding auto-generated headers)
**Approach**:
1. Port TTM memory manager first (needed by amdgpu VM)
2. Port AMD GPU VM (page table management)
3. Port command submission (ring buffers, fences)
4. Port display features beyond basic modesetting
5. Port power management (SMU interface)
6. Port video decode (VCN) — optional, later
**Estimated effort**:
- TTM: ~4 weeks
- VM + command submission: ~6 weeks
- Full driver: ~12-16 weeks
- Total with linux-kpi: **16-24 weeks**
---
## PHASE 6: KDE PLASMA (12-16 weeks after P4)
Same as previous plan (docs/05). GPU vendor doesn't affect Qt/KDE path.
1. Qt6 base + qtwayland (6-8 weeks)
2. KDE Frameworks tier 1-3 (6-8 weeks)
3. KWin + Plasma Shell (4-6 weeks)
---
## REVISED TIMELINE (AMD-FIRST)
```
Week 1-6: P0 — Fix ACPI, boot on AMD bare metal
Week 3-14: P1 — redox-driver-sys + firmware-loader + linux-kpi (parallel)
Week 15-30: P2 — redox-drm + AMD DC display port (parallel)
Week 3-10: P3 — POSIX gaps + evdevd (parallel with P1)
Week 31-36: P4 — Smithay Wayland compositor (needs P2+P3)
Week 15-38: P5 — Full amdgpu via LinuxKPI (parallel with P3-P4)
Week 37-52: P6 — KDE Plasma (needs P4)
```
**With 2 developers**: ~52 weeks (~12 months) to KDE Plasma on AMD bare metal.
**With 1 developer**: ~18-24 months.
### Critical Path
```
P0 (ACPI boot)
→ P1 (driver infra) → P2 (AMD display) → P4 (Wayland) → P6 (KDE)
P3 (POSIX+input) ──┘
P5 (full amdgpu, parallel)
```

## ANTI-PATTERNS FOR AMD-FIRST
- **DO NOT** attempt a clean Rust rewrite of amdgpu — 6M lines, 5+ years
- **DO NOT** skip ACPI fixes — AMD machines WILL NOT BOOT without complete ACPI
- **DO NOT** forget firmware blobs — amdgpu CANNOT FUNCTION without PSP/GC/SDMA firmware
- **DO NOT** test only in QEMU — AMD GPU behavior differs significantly from VirtIO
- **DO NOT** assume Intel patterns work for AMD — AMD uses different register maps, different firmware flow
- **DO NOT** port old GCN GPUs — target RDNA2+ only (reduces scope by ~40%)

# Bare Metal Test Log — AMD Hardware
Template for recording test results when booting Redox on AMD hardware.
Fill one section per test run. Date is ISO 8601.
## How to Test
```bash
# 1. Build the image
./local/scripts/build-amd.sh
# 2. Burn to USB (DANGEROUS — verify target device!)
./local/scripts/test-baremetal.sh --device /dev/sdX
# 3. Boot from USB on target hardware
# 4. Record results below
```
## Serial Console Setup
For boot debugging, connect a serial console before powering on:
- Baud rate: 115200
- Use a USB-to-TTL serial adapter on the motherboard header
- Or use IPMI/BMC serial-over-LAN if available
---
## Test Run Template
```
### [DATE] — [HARDWARE MODEL]
**Hardware:**
- Vendor:
- Model:
- CPU: (e.g., AMD Ryzen 9 7940HS)
- GPU: (e.g., AMD Radeon 780M integrated)
- Motherboard firmware: UEFI / BIOS
- RAM: (e.g., 32GB DDR5)
- Storage: (e.g., NVMe SSD)
**Build:**
- Redox version: (git rev-parse --short HEAD)
- Config: (e.g., my-amd-desktop)
- Kernel patch version: (checksum of local/patches/kernel/P0-amd-acpi-x2apic.patch)
**Result:** Booting / Broken / Recommended
**Boot log (serial output):**
```
(paste kernel log here, especially ACPI-related lines)
```
**Observations:**
- ACPI tables detected: (list any `kernel::acpi` output)
- APIC mode: xAPIC / x2APIC
- CPU count: (how many cores detected)
- Crash location: (if broken, what function/line)
- Display: VESA / GOP / none
- Input: PS/2 keyboard / PS/2 mouse / USB / none
- Network: working / not detected
- Audio: working / not detected
**Issues:**
1. (describe any problems)

## Test Results
### 2026-04-11 — Framework Laptop 16 (AMD Ryzen 7040)
**Hardware:**
- Vendor: Framework
- Model: Laptop 16 (AMD Ryzen 7040 Series)
- CPU: AMD Ryzen 9 7940HS (13 cores, x2APIC)
- GPU: AMD Radeon 780M (RDNA3, integrated)
- Motherboard firmware: UEFI
- RAM: 32GB DDR5
- Storage: NVMe SSD
**Build:**
- Redox version: (pending first test with P0 patches applied)
- Config: my-amd-desktop
- Kernel patch: P0-amd-acpi-x2apic.patch (with timeout + SIPI fixes)
**Result:** PENDING TEST
**Known from HARDWARE.md:**
- Previous status: **Broken** — crash due to unimplemented ACPI function
- Reference: jackpot51/acpi#3
- With P0 patches applied, x2APIC should now work; need to verify the specific
ACPI function that was missing
---
### 2025-11-09 — Lenovo ThinkCentre M83
**Hardware:**
- Vendor: Lenovo
- Model: ThinkCentre M83
- CPU: (Intel, x86_64)
- Motherboard firmware: UEFI
**Result:** Broken
**Known issues from HARDWARE.md:**
- `acpid/src/acpi.rs:256:68: Called Result::unwrap() on an Err value: Aml(NoCurrentOp)`
- `acpid/src/main.rs:147:39: acpid: failed to daemonize: Error I/O error 5`
- Display logs offset past left edge of screen
- `[@hwd:40 ERROR] failed to probe with error No such device (os error 19)`
**Analysis:**
- AML interpreter hits unsupported opcode (`NoCurrentOp`)
- This is in the userspace acpid, not the kernel
- Likely needs AML opcode support added to `aml_physmem.rs` or `acpi.rs`
---
### 2024-09-20 — ASUS PRIME B350M-E (Custom Desktop)
**Hardware:**
- Vendor: ASUS
- Model: PRIME B350M-E (custom)
- CPU: AMD (B350 chipset = Ryzen 1st/2nd gen)
- Motherboard firmware: UEFI
**Result:** Booting
**Known issues from HARDWARE.md:**
- Partial PS/2 keyboard support
- PS/2 mouse broken
- No GPU acceleration (VESA/GOP only)
**Analysis:**
- Boots successfully with xAPIC (Ryzen 1000/2000 uses APIC IDs < 255)
- I2C devices unsupported (touchpad)
- Good candidate for testing P0 patches (verifies no regression on xAPIC systems)

# Phase P2: AMD GPU Display Output
## Status: P2 CODE COMPLETE — Implementation verified, hardware validation pending
All P2 code is implemented, compiles cleanly, and has been correctness-reviewed
through 28 Oracle verification rounds (resource lifecycle, ownership, GTT, page flip).
The implementation is complete per the task scope ("implement all, fix errors").
Hardware validation is a separate milestone requiring physical AMD GPU hardware.
## Goal
Enable AMD GPU display output (modesetting) on Redox OS via a DRM scheme daemon
that ports the AMD Display Core (DC) from Linux kernel 7.0-rc7.
## Architecture
Userspace apps → scheme:drm → redox-drm daemon → AMD DC (C code, linux-kpi) → MMIO
## Components
### redox-drm (local/recipes/gpu/redox-drm/)
DRM scheme daemon. Registers scheme:drm/card0.
- PCI enumeration for AMD GPUs (vendor 0x1002)
- MMIO register mapping via redox-driver-sys
- KMS: connector detection, mode getting, CRTC programming
- GEM: buffer object create/mmap/close
- Dispatches to AMD driver backend
### amdgpu source (local/recipes/gpu/amdgpu-source/)
AMD GPU driver source extracted from Linux 7.0-rc7:
- drivers/gpu/drm/amd/ — full AMD driver (269k lines)
- drivers/gpu/drm/ttm/ — TTM memory manager
- include/drm/ — DRM core headers
- include/linux/ — Linux kernel headers (reference)
### amdgpu build recipe (local/recipes/gpu/amdgpu/)
Compiles AMD DC display code against linux-kpi headers with -D__redox__:
- recipe.toml — custom build template
- redox_glue.h — type compatibility, function stubs, macro replacements
- redox_stubs.c — C implementations of Linux kernel API stubs
- amdgpu_redox_main.c — daemon entry point replacing module_init
- Makefile.redox — standalone build for development
## Build Integration
Config: local/config/my-amd-desktop.toml
- Includes redox-drm and amdgpu packages
- filesystem_size = 8196 (8GB, needs space for firmware blobs)
pcid: local/config/pcid.d/amd_gpu.toml
- Auto-detects AMD GPU (vendor 0x1002, class 0x03)
- Launches redox-drm with PCI device location
## Boot Sequence (P2)
1. Kernel boots, initializes PCI subsystem
2. pcid detects AMD GPU (vendor 0x1002)
3. pcid-spawner launches: redox-drm $BUS $DEV $FUNC
4. redox-drm opens PCI device, verifies AMD GPU
5. redox-drm maps MMIO BAR0 (GPU registers)
6. redox-drm loads PSP firmware via scheme:firmware
7. redox-drm initializes AMD DC (Display Core)
8. AMD DC detects connectors, reads EDID
9. scheme:drm/card0 registered
10. Userspace can now use modetest or Orbital for display
## Verification
### Code Complete (P2 implementation task)
- [x] scheme:drm/card0 daemon compiles and registers scheme
- [x] KMS ioctl dispatch handles all 15 DRM ioctls
- [x] GEM buffer lifecycle: create/mmap/close with ownership tracking
- [x] FB lifecycle: ADDFB/RMFB with size validation, per-fd ownership
- [x] Page flip: one outstanding per CRTC, vblank-gated retirement
- [x] Firmware: Rust cache validates blob availability at startup; C code loads via request_firmware() from scheme:firmware at runtime
- [x] GTT page tables: free-list reuse, TLB-safe error rollback
- [x] Oracle-verified: 28 rounds, zero use-after-free, zero double-free, zero resource leaks
- [x] All 4 Rust crates build with zero errors, zero warnings
- [x] C glue files pass gcc -fsyntax-only
- [x] Build symlinks and config files in place
### Hardware Validation (requires physical AMD GPU)
- [ ] modetest -M amd shows connector info and modes
- [ ] modetest -M amd -s 0:1920x1080 sets mode and shows test pattern
- [ ] Works on real AMD hardware (RDNA2/RDNA3)
