All 58 base patches now pass repo validate-patches base.
- P18-9-msi-allocation-resilience: regenerated against P0-P18-8 baseline
with correct upstream content (deamon typo preserved for virtio-netd)
- P19-init-startup-hardening: regenerated against P0-P18-9 baseline
- P19-acpid-startup-hardening: regenerated against P0-P18-9 + P19-init
baseline with all 39 hunks in -U0 -w format (zero context lines)
x2APIC ICR mode fix cannot be a forward patch because P16-1-sipi-timing
references the ICR line as context. Modifying P1 (which introduces the line)
would require updating P16-1's offsets. Will address by consolidating into
an existing early patch in a future revision.
- Add RawFb struct: direct framebuffer rendering via physmap
- Add RawTextScreen: simple text renderer using orbclient font
- Fallback in FbbootlogScheme::new() when V2GraphicsHandle fails
- Reads FRAMEBUFFER_ADDR/WIDTH/HEIGHT/STRIDE from bootloader env
- Scroll via ptr::copy on pixel rows, clear bottom line
- No DRM, no shadow buffer, no GPU required — like MS-DOS text mode
- Add common dependency to fbbootlogd Cargo.toml
- Derived line offsets from real pre-P20 vs post-P20 diff
- x86.rs: 3 hunks at @@ -446/-456/-468 converting hardcoded <<32 to
local_apic.x2-gated format with xAPIC <<56 fallback
- local_apic.rs: 1 hunk promoting debug! to info! for bootlog visibility
- Fix LocalX2Apic handler: use local_apic.x2 to select correct ICR
format (<<32 for x2APIC, <<56 for xAPIC) instead of hardcoded <<32
- Promote x2APIC/xAPIC detection from debug! to info! for bootlog
- Document build system durability in AGENTS.md: cardinal rule,
two-layer architecture, correct workflow, anti-patterns
P5: Enable PRIME export for GBM dumb buffers so virgl can import scanout\nbuffers via fd-to-handle.
P6: Add redox_probe_device_hw() that opens /scheme/drm/card0, resolves the\nDRI driver via PCI ID lookup (loader_get_driver_for_fd), and initializes the\nhardware path through dri2_load_driver_dri3 with __DRIimageLoaderExtension.\nIncludes fprintf(stderr) debug logging tagged [REDOX-EGL] for tracing the\nHW init sequence. Falls back to software rendering if HW probe fails.
Wire P1/P2 patches into recipe.toml. Source reflects the full ioctl bridge\nrewrite: VirtGPU NR mappings, EXECBUFFER/GET_CAPS special handlers,\nPCI info bridge for drmGetDevice2, and removal of the old per-ioctl C\nhandler functions in favor of unified redox_drm_simple_ioctl() dispatch.
P1: Replaces the old per-ioctl C handlers with a unified dispatch through\nredox_drm_simple_ioctl(), adds VirtGPU NR mappings (MAP, EXECBUFFER,\nGETPARAM, RESOURCE_CREATE, GET_CAPS, etc.), and special handlers for\nEXECBUFFER (inline command buffer) and GET_CAPS (variable response).
P2: Adds __redox__ blocks to drmParsePciBusInfo, drmParsePciDeviceInfo,\nand drmGetDevice2 using the DRM scheme GET_PCI_INFO ioctl to populate\nPCI device identification without /sys access.
Align 2D command opcodes, response opcodes, and 3D command opcodes with\nthe Linux UAPI definitions in include/uapi/linux/virtio_gpu.h. Enable\nVIRTIO_GPU_F_VIRGL feature negotiation during device initialization to\nactivate the virgl 3D rendering path.
VirtIO capability structures can start at non-page-aligned offsets within\nBARs. The kernel physmap requires page-aligned addresses. Align the physical\naddress down, adjust the size, and apply the page offset to the returned\npointer. Track the original map pointer/size separately for correct unmapping.
The previous BAR size calculation used !(inverted & mask) & mask which\nproduces incorrect results when the BAR has a non-zero base address.\nUse lowest-set-bit extraction (masked & (!masked + 1)) to correctly\ncompute the BAR size from the writable bit pattern read back from hardware.
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.
Add P0-disable-qml-quick.patch for building KWin without QML/Quick
dependencies. Update greeter scripts to prefer kwin_wayland. Enable
kwin in redbear-full config.
Consolidate ~30 absorbed base patches into surviving carriers. Add
new init service files, driver sources, and network/storage modules
for the base recipe. Move absorbed patches to local/patches/base/absorbed/.
