AMD display driver: expanded DCN pipeline setup with plane/controller/stream mapping.
Intel driver: cleaned up module structure.
New interrupt module for MSI-X vector management across GPU drivers.
PCID config endpoint patch and Intel GPU TOML for automatic driver spawning.
Expanded redox_stubs with additional kernel API shims.
Rebuild base/acpid patch as comprehensive unified diff combining: DMAR iterator fix, FADT shutdown via PM1a/PM1b CNT_BLK with S5 sleep types from _S5 AML, ACPI reset register reboot with keyboard controller fallback (port 0x64, 0xFE), and power methods (_PS0/_PS3/_PPC). GenericAddress now supports memory-mapped and I/O port writes. Reboot wired into main.rs event loop with reboot_requested flag. All ivrs/mcfg stub references removed. Validated with git apply --check against upstream base source.
The base patch referenced ivrs and mcfg modules that don't exist in the source tree, causing build failures. Removed the module declarations, imports, and init calls. MCFG is already handled by pcid (the PCI daemon). IVRS (AMD IOMMU) needs real implementation, not a stub. DMAR iterator fix and Dmar::init() call preserved.
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
