Cross-referenced with Linux 7.1 drivers/usb/core/hub.c port event
handling and drivers/usb/core/driver.c device-driver binding.
New daemon (216 lines) that watches USB controllers for device
attachment/detachment and auto-spawns the appropriate class driver.
Architecture:
- Polls /scheme/usb/ every 1000ms for controller directories
- For each controller, enumerates root hub ports
- Reads device descriptors (class/subclass/protocol) via XhciClientHandle
- Maps class to driver binary: HID(0x03)→usbhidd, Storage(0x08)→usbscsid,
Hub(0x09)→usbhubd
- Spawns driver with <scheme> <port> <protocol> arguments
- Tracks spawned Child processes in HashMap<port_path, TrackedDevice>
- Detects disconnection (descriptor read fails) → kills driver + removes
from tracking
- Detects driver exit (try_wait) → removes from tracking
- Skips hub interfaces (usbhubd handles its own children)
Config:
- Added to redbear-mini.toml (inherited by redbear-full)
- Auto-started via 02_usb_hotplug.service (oneshot_async, after base.target
and pcid-spawner)
Driver map supports: HID (0x03), Mass Storage (0x08 with BOT protocol),
Hub (0x09). Additional class drivers extendable via DRIVER_MAP constant.
Add redbear-usb-storage-check in-guest binary that validates USB mass
storage read and write I/O: discovers /scheme/disk/ devices, writes a
test pattern to sector 2048, reads it back, verifies match, restores
original content. Updates test-usb-storage-qemu.sh with write-proof
verification step.
Includes all accumulated Red Bear OS work: kernel patches, relibc
patches, driver infrastructure, DRM/GPU, KDE recipes, firmware,
validation tooling, build system hardening, and documentation.
Consolidate the active desktop path around redbear-full while landing the greeter/session stack and the runtime fixes needed to keep Wayland and KWin bring-up moving forward.
CUB (Red Bear OS Package Builder) is a Rust CLI tool that combines package management and building:
- RBPKGBUILD parser (TOML format) with full spec support
- Cookbook adapter converting RBPKGBUILD to recipe.toml
- PKGBUILD (Arch AUR) to RBPKGBUILD conversion with Linuxism detection
- Dependency mapping (Arch to Redox names)
- pkgar package creation integration
- Build environment setup with Cookbook env vars
- CLI with pacman-style shortcuts: -S, -Ss, -B, -G, -Pi, -Sua, -Sc, --import-aur
28 cub-lib tests passing. cub-cli compiles with local pkgutils.
Added cub = {} to redbear-desktop, redbear-full, redbear-minimal configs.
Created recipe symlink and updated integrate-redbear.sh.
Replace all 'rbos'/'RBOS' references with 'redbear'/'Red Bear OS'
across the build system, scripts, docs, and configs. Renamed files:
rbos.ipxe → redbear.ipxe
assets/rbos-icon.png → assets/redbear-icon.png
recipes/system/rbos-info → recipes/system/redbear-info
Added redbear-info: a system tool that enumerates all Red Bear OS
custom components, checks runtime availability via scheme paths and
binary presence, and prints status/test info. Supports --verbose,
--json, and --test output modes. Zero external dependencies.
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
