Expand XhciControllerQuirkFlags from 7 to all 51 flags defined in
Linux 7.1 xhci.h:1587-1649, each using 1u64 << N matching the kernel
bit positions. Add XhciQuirkEntry struct with vendor/device/revision
matching and a WILDCARD constant for catch-all rules.
Create xhci_table.rs — the canonical controller quirk table ported
from Linux 7.1 xhci-pci.c:xhci_pci_quirks() (lines 251-517). Covers
~85 entries across all vendors (Fresco Logic, NEC, AMD, ATI, Intel,
ETRON, Renesas, VIA, CDNS, Phytium, ASMedia, TI, Broadcom, Cavium,
Zhaoxin). 38 unit tests verify flag assignment for every vendor family.
Update lookup_xhci_controller_quirks_full() signature to accept
revision: u8 and hci_version: u16, enabling the two table entries
that depend on hci_version (AMD_0x96_HOST, >= 0x120 spec rule).
Bugs fixed vs xhcid's prior self-contained table:
- Intel 0x9c31 duplicate removed; WildcatPoint corrected to 0x9cb1
- Panther Point corrected to 0x1e31
- VIA VL805 corrected to LPM_SUPPORT + TRB_OVERFETCH
- Phytium corrected to RESET_ON_RESUME
- ASMedia 0x1142 corrected to NO_64BIT_SUPPORT + ASMEDIA_MODIFY_FLOWCONTROL
- Intel 0x9a13 moved off RESET_TO_DEFAULT list
xhcid now consumes this canonical path via a thin re-export shim
(base submodule pointer bumped to 9fc1947d).

- Add x11proto to redbear-full.toml package list
- libxau recipe updated with x11proto dependency and custom build script
- Fixes libxau build failure: 'Package xproto was not found'
Core fixes to get redbear-mini building and booting via UEFI:
relibc: Use 'VaListImpl as va_list' in syslog so cbindgen outputs va_list
instead of unknown VaListImpl type (matches stdio pattern). Fixes
openssl3 and all C consumers of syslog.h.
base fork (f97da5b0): ps2d missing info! import, ps2d dead variable,
fbcond drm-0.15 API fix, acpid 31 errors (ivrs/mcfg modules, duplicate
methods, packed fields, dmar copy-paste bug), bootstrap abort_immediate
removal (feature removed from nightly)
redox-driver-sys: Add PciQuirkFlags re-export for crate-root imports
bash: Regenerate P1-mksyntax-host-headers.patch with proper unified diff
m4: Fix getlocalename_l unsafe wrapper
config: Comment out mc (requires glib-2.0 chain, not needed for mini)
UEFI boot verified in QEMU — boots to RedBear login prompt.

The redox arm of acquire_iopl was using 'crate::Result' which is a
1-generic type alias. Use std::result::Result<(), Error> instead.
Also rename unused 'product' param to '_product' in lookup_hid_quirks.
io.rs uses redox_syscall::dup, ::CallFlags, ::ProcSchemeVerb but was
missing the 'use syscall as redox_syscall' alias (was removed earlier
because cargo check passed locally without it, but actual build needs it).
Also fixed: the non-redox arm of acquire_iopl was using crate::Result
which is a 1-generic type alias; std::result::Result with 2 generics
is what's needed here.
Removed leftover cfg attribute and duplicate use crate::Result.
usbhidd references redox_driver_sys::quirks::HidQuirkFlags and
redox_driver_sys::quirks::lookup_hid_quirks. Add these to unblock
HID driver compilation.
Add types referenced by acpid/pcid/xhcid but missing from redox-driver-sys:
- AcpiQuirkFlags: 15 flag variants (OSI disable, battery, lid, sleep)
- ChipsetQuirkFlags, ClocksourceQuirkFlags, CpuBugFlags, UsbAudioQuirkFlags:
empty bitflag structs (full implementation is follow-up)
- ConfigWriteWidth enum, QuirkAction enum, PciConfigWriter trait
- PciQuirkLookup struct, lookup_pci_quirks_full function
- XhciControllerQuirkFlags: 7 variants
- lookup_xhci_controller_quirks_full function
- load_dmi_acpi_quirks function
- Missing PciQuirkFlags: NO_PM_RESET, NO_FLR, BROKEN_INTX_MASKING, NO_PME
- Default impl on PciQuirkFlags (required by lookup return)
Also restored 'use syscall as redox_syscall' alias to all source files
since the redox_syscall crate (0.7.x and 0.8.x) exposes itself as 'syscall'.
This unblocks compilation of base fork's pcid, acpid, xhcid daemons.
The redox_syscall crate (0.7.x and 0.8.x) has [lib].name = 'syscall',
so the crate is exposed as 'syscall' in source code, not 'redox_syscall'.
Without the alias, all 'use redox_syscall::...' imports fail to resolve.
Also fixed:
- lib.rs:46,86 'redox_syscall::error::Error' (now resolves via alias)
- io.rs:23 'Result<()>' -> 'Result<(), crate::DriverError>' (Result needs 2 generics)
- Cargo.toml: pin redox_syscall to 0.7 to match the rest of base fork
This restores redox-driver-sys compilation against base fork 0.2.3
reset to redbear-working.
Add missing alloc_cpu_id() function (atomic round-robin CPU selection).
Fix type chain: MsiAllocation.irq u8→u32 to match allocate_irq_vector
return type. irq_set_affinity accepts u32 irq for consistency.
Verified: driver-sys compiles on Linux (x86_64-unknown-linux-gnu).
Full redbear-mini image builds and boots in QEMU.
dma.rs: IommuDmaAllocator (145 lines)
- New struct wires existing IOMMU daemon (1003 lines) to existing DmaBuffer (261)
- allocate(): phys-contiguous alloc via scheme:memory, then MAP through IOMMU domain
- unmap(): sends UNMAP to IOMMU domain, releases IOVA
- Inlined IOMMU protocol constants — no new crate dependency
- encode_iommu_request/decode_iommu_response for scheme write/read cycle
Documentation updates:
- IMPLEMENTATION-MASTER-PLAN.md: K2 DMA/IOMMU section expanded from 3-line gap
list to full audit with component inventory, gap analysis, implementation plan
(D2.1-D2.5), Linux reference table. Added K2b thread/fork audit.
- CPU-DMA-IRQ-MSI-SCHEDULER-FIX-PLAN.md: Phase 1 (MSI) marked complete with
per-task status. Phase 2 (DMA) re-scoped from 'create' to 'wire' based on
audit. Phase 3 (scheduler) marked mostly done.
- IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md: kernel MSI support noted
as materially strong with P8-msi.patch reference.
Audit findings:
- IOMMU daemon is solid: 1003-line lib.rs with full scheme protocol,
427-line amd_vi.rs, host-runnable tests. Needs wiring, not rewriting.
- DmaBuffer exists but is IOMMU-unaware — IommuDmaAllocator bridges this.
- relibc rlct_clone is correct for threads (shares addr space implicitly).
'3 IPC hops' claim is microkernel-architectural, not a real perf issue.
- No stale docs to archive at this time.
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.
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
