- Fix bootloader recipe: pass correct TARGET on make command line
instead of hardcoding x86_64-unknown-uefi (breaks BIOS build)
- Add cargo -Zunstable-options to x86_64-unknown-uefi.mk and
x86-unknown-none.mk for custom target support
- Add x86_64-unknown-uefi.json target file
Remaining: redoxer toolchain cargo/rust-src version mismatch
prevents build-std compilation. Needs 'make prefix' to rebuild
toolchain with matching versions.
Bootloader needs x86_64-unknown-uefi (UEFI target) but redoxer
sets TARGET=x86_64-unknown-redox (OS target). Added:
- x86_64-unknown-uefi.json custom target file
- cargo -Zunstable-options in Makefile for custom target support
- TARGET= override in recipe (may still be overridden by redoxer)
Root cause chain discovered and fixed:
1. GCC built-in stddef.h shadowed by relibc's _STDDEF_H guard
→ fix_types.h with guarded typedefs for 15+ sys types
2. gnulib configure bakes raw typedefs into GL_CFLAG_GNULIB_WARNINGS
→ strip them from Makefiles after configure
3. __fseterr/__freadahead don't exist in relibc
→ compile C stubs and inject into link via Makefile patch
The recipe pattern is documented and reusable for other gnulib packages
(ninja-build, diffutils, etc.).
Also: bootloader recipe needs RUSTFLAGS=-Zunstable-options for
custom target support after redoxer toolchain restore.
- Create source symlinks for all 7 core components (kernel, relibc, base,
bootloader, installer, redoxfs, userutils) pointing at local/sources/
- Create redoxfs and userutils fork repos from frozen 0.1.0 archives
- Fix relibc-tests recipes: replace patch commands with direct fork build
- Archive all 417 patch files to local/archived/patches-2026-06-migration/
- Full AGENTS.md rewrite: remove all 31 remaining stale patch references,
update DURABILITY POLICY to describe git commit workflow, update WHERE TO
LOOK table, fix build flow description, replace Recipe Patch Wiring section
with Recipe Source Configuration
- Zero active patches = [...] arrays remain in any recipe.toml file
- All 13 remaining grep hits for 'patches' are TODO comments in WIP recipes
Red Bear OS is a full fork. All sources must be available from git clone
with zero network access. Removed gitignore rules that excluded fetched
source trees under recipes/*/source/, local/recipes/kde/*/source/,
local/recipes/qt/*/source/, and vendor source trees.
Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded.
127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt
frameworks, mesa, wayland, DRM drivers, and every other recipe source.
Bootloader hardcoded RedoxFS partition offset at 2 MiB, which fails when
efi_partition_size > 1 (redbear-full, redbear-grub use 16 MiB, placing
RedoxFS at LBA 34816 = 17 MiB). Added GPT partition table parser that
scans for Linux filesystem GUID (0FC63DAF) to find the actual offset.
Also removed invalid 'respawn = true' from 31_debug_console.service in
redbear-full.toml — init's service format does not support this field.
Verified: all three ISOs boot in QEMU UEFI and reach login prompt.
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.
Bootloader: alloc_zeroed_page_aligned no longer panics on OVMF
AllocatePages failure. Returns null on error.
Cookbook: pkgar falls back to repo/ dir when target pkgar missing.
Resolves KDE build chain failure.
redbear-full: builds 4.0GB image+ISO, boots without crash.
5-second countdown with any-key cancel into manual mode selection. Defaults to 1280x720, falls back to EDID best resolution. UEFI only via get_key_timeout polling with BootServices.Stall.
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
