- Fix ASIC detection: use PCI device_id instead of broken MMIO offset-0 read.
Add proper device_id->ASIC family lookup table covering Navi10-Navi33 (RDNA1/RDNA2/RDNA3).
Add per-family properties (DCN revision, firmware name, OTG/HUBP base offsets, HPD register).
- Wire quirk flags from Rust to C: replace pci_get_quirk_flags/pci_has_quirk stubs
(previously always returned 0/false) with stored quirk_flags set via new FFI
redox_pci_set_quirk_flags(). Quirk-aware IRQ policy now actually works.
- Store firmware blobs from Rust to C: add redox_firmware_store() FFI to pass
firmware blobs from AmdDriver.firmware HashMap into C-side storage. C side
can now fall back to scheme:firmware if blobs not pre-stored.
- Fix connector descriptors: replace hardcoded 600x340mm fake dimensions with
per-ASIC-family connector tables (desktop dGPU vs APU layout). Set mm_width/
mm_height to 0 (unprobed — needs DC hardware detection). HPD register offset
now comes from per-family asic_props table.
- Fix register offsets: replace hardcoded OTG base 0x4800 / HUBP base 0x5800
(Navi23-specific) with per-DCN-revision dispatch from asic_props table
(DCN2.0=0x4000/0x5000, DCN3.0=0x4800/0x5800, DCN3.2=0x5000/0x6000).
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.
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.
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
