CONSOLE-TO-KDE-DESKTOP-PLAN: v6.0 comprehensive rewrite with unified input + KWin compositor decision
This is a full v6.0 rewrite of the desktop plan, produced after:
1. Booting CachyOS desktop ISO (cachyos-desktop-260426.iso, 2.9GB) in QEMU
11.0.0 to establish the reference baseline.
2. Six parallel research agents that audited the full Red Bear stack
against the CachyOS reference and Linux 7.1 kernel source.
3. Resolution of two architectural questions that v5.x punted on.
Two non-negotiable architecture decisions (v6.0):
A. UNIFIED INPUT ARCHITECTURE: every input driver writes to BOTH
/scheme/input/orbclient (for Orbital) and /scheme/input/evdev (for
KWin + libinput). No more inputd <-> evdevd bridge that loses
metadata (timestamps, axis ranges, vendor IDs, SYN_REPORT).
Matches CachyOS/Linux: one kernel-evdev path, all consumers
read from it.
B. KWIN IS THE PRIMARY COMPOSITOR: redbear-compositor (788-line
Rust) is too small to reach production parity with KWin in any
realistic timeframe. KWin is used for the user session;
redbear-compositor hosts only the greeter (minimal xdg-shell +
wl_keyboard events are still needed for the greeter to function).
Critical path rework (v6.0):
- Phase 0: QML JIT gate (4-6 weeks) — moves to pre-flight because
it blocks 12 KF6 packages and KWin. Without QML, no Plasma.
- Phase 1: Unified input (1-2 weeks) — resolves the inputd/evdevd
proliferation.
- Phase 2: DRM atomic modeset + render node + PRIME real FDs +
RESOURCE_MAP_BLOB (2-3 weeks).
- Phase 3: Mesa EGL Wayland fix (1 week).
- Phase 4: Compositor greeter — redbear-compositor adds
xdg-shell + wl_keyboard events (2-3 weeks).
- Phase 5: KWin real build (2-4 weeks).
- Phase 6: PipeWire + wireplumber + audiod bridge (6-8 weeks).
- Phase 7: Plasma shell (4-6 weeks).
- Phase 8: QEMU E2E validation (1-2 weeks).
- Phase 9: Intel ARC track (parallel) (12-20 weeks).
Coverage inventory (v6.0):
237 components audited across 14 categories.
86 real (36%), 41 partial (17%), 110 missing (46%).
Detailed gap matrix in §8.
Intel ARC support:
Added as Phase 9 parallel track — requires Mesa iris + Xe driver
cross-compile + real hardware validation.
Total: 22-32 weeks to functional software-rendered KDE Plasma
Wayland desktop on QEMU. +4-8 weeks for Mesa virgl. +12-20 weeks
for real Intel ARC hardware.
This supersedes v5.0 and v5.1 in full. The v5.x changelog sections
(§9, §9.1, §9.1.1) are retained as historical record.

virtio-inputd: review-driven fixes for BLOCKERs and MAJORs (Phase 5.1 hardening)
Two parallel review agents cross-checked the virtio-inputd driver against
the Linux 7.1 reference (drivers/virtio/virtio_input.c, virtio_input.h)
and the proven redox-drm virtio transport. 12 issues were found across
BLOCKER, MAJOR, MINOR, and NIT severity, all fixed in this commit before
runtime testing.
BLOCKERs (would have prevented the driver from working in QEMU):
1. fill_avail() never wrote avail_idx after pushing the 64 ring
entries. The device reads avail_ring[avail_idx % size] to discover
new buffers, so without publishing avail_idx = size, the device
saw avail_idx = 0 and ignored all initial buffers. Fix: explicit
'fence(Release); write_avail_idx(self.size)' with a spec citation.
2. drain() recycled IDs derived from 'last_used_idx - drained_count',
which is wrong when the used ring wraps and a single drain cycle
spans more than one full ring revolution. Fix: collect the actual
drained 'id' values in a stack '[u16; 64]' array during the drain
loop, then push those exact ids back to the avail ring. The
doc-comment explains why the derivation is unsafe.
3. config_read_string() and config_read_bitmap() used
'self.device_cfg.size()' (the MMIO region size = 40) instead of
the device-reported config size from offset 2. Fix: use
'config_read_size()' to read the actual size field.
4. config/redbear-full.toml: device_id_range was a TOML string
('0x1042..=0x107F') but serde's Range<u16> deserializes from a
sequence, not a string. pcid-spawner would have silently failed
to load the fragment. Fix: use serde array form
'device_id_range = [0x1042, 0x107F]'.
MAJORs (silent failure modes or runtime bugs):
5. activate_queue() had no fence between address writes and
'queue_enable = 1'. A CPU write buffer may reorder writes to
distinct MMIO addresses. Fix: explicit 'fence(SeqCst)' with
a comment citing virtio spec 2.8 and Linux's virtio_wmb.
6. No 'reset_device()' on error path after partial init. The device
would be left in ACKNOWLEDGE|DRIVER with no driver active,
requiring a guest reboot to recover. Fix: wrap init in a closure;
any error calls 'transport.reset_device()' before propagating.
7. Drain loop never checked DEVICE_NEEDS_RESET or DEVICE_STATUS_FAILED.
If the device entered an unrecoverable state, the driver would
poll forever with stale state. Fix: 'device_in_error_state()' on
the transport; loop checks it each iteration and exits cleanly.
8. The abs_count probe used 'config_read_size() == 24', which was
always false (virtio_input_absinfo is 20 bytes, not 24). The
count was always logged as 0. Fix: '>= 20' per spec.
MINORs / NITs (hardening, no functional impact):
9. config_read_absinfo() returned AbsInfo without validating
device-reported size. Now returns Option<AbsInfo> and validates
size >= 20.
10. map_cap_region() missing bounds check: capability range may
extend past BAR end (QEMU is permissive; bare-metal is not).
Added 'cap_end > bar_size' check with spec reference.
11. Legacy device 0x1052 entry in pcid fragment caused spurious
spawn + log noise. Removed.
12. notify_queue() error silently dropped with .ok(). Now logs warn
and continues.
Plan update:
The CONSOLE-TO-KDE-DESKTOP-PLAN.md v5.1 changelog now has a new
'9.1.1 Phase 5.1 review-driven fixes' section documenting all 12
findings with file:line, severity, and fix. Future maintainers can
trace the BLOCKERs back to specific commits to understand the
critical-path safety net this review provided.
Verification: cargo check zero errors, 64 warnings (all unused
keycode constants reserved for Phase 5.2 expansion). The driver
is now ready for runtime testing in QEMU.

virtio-inputd: implement Phase 5.1 virtio-input driver
Add a real, QEMU-targeted virtio-input driver as a new Red Bear recipe at local/recipes/drivers/virtio-inputd/. The driver handles virtio-input-host-pci, virtio-input-keyboard, virtio-input-mouse, and virtio-input-tablet devices and closes Gap #19 of the v5.0 desktop plan. The driver: * Walks the PCI capability list to find the modern virtio 1.0 capability block (common_cfg, notify_cfg, isr_cfg, device_cfg) using MmioRegion mappings via redox-driver-sys. Rejects legacy virtio-input (device 0x1052) which lacks the modern transport. * Negotiates VIRTIO_F_VERSION_1 only (the only required feature). * Allocates one event virtqueue (size up to 64) backed by four DMA buffers (desc, avail, used, event_buffers) and pre-fills the avail ring. * Polls the used ring at 60 Hz, drains completed events, decodes each virtio_input_event (8-byte type/code/value), and recycles drained buffers back to the avail ring. * Translates events to orbclient format and pushes them to inputd via ProducerHandle (Orbital path): - EV_KEY -> KeyEvent (with US-QWERTY character mapping) - EV_REL -> MouseRelativeEvent (REL_X/REL_Y) or ScrollEvent (REL_WHEEL) - EV_SYN -> dropped (inputd multiplexes) - Other -> dropped (Phase 5.2 will add evdevd path) Probe-time checks: * Vendor 0x1AF4, device_id >= 0x1042, revision >= 1 * Caps include a device_cfg block with virtio type == 18 (virtio_input) Configuration: a pcid-spawner fragment is added to config/redbear-full.toml under /etc/pcid.d/virtio-inputd.toml matching class=0x09 vendor=0x1AF4 with device_id_range 0x1042..=0x107F (and a separate 0x1052 entry that the driver intentionally rejects). Verification: cargo check produces 0 errors and 65 warnings, all of which are unused input-event-codes.h constants reserved for the Phase 5.2 expansion. Linking the binary requires the Redox cross-toolchain (relibc provides redox_sys_call_v0); this is provided by the build system, not the host toolchain. Plan: this is Phase 5.1 of CONSOLE-TO-KDE-DESKTOP-PLAN.md v5.0. The plan is updated to v5.1 with: (a) a 'What Changed Since v5.0' section, (b) Gap #19 marked DONE, (c) Phase 5 row marked DONE with sub-task status, (d) Gate E updated, (e) Input pipeline section updated to reflect the (c) path is now implemented. Phase 5.2 (evdevd producer path + virtio-snd) is documented as the next planned work but not yet implemented. |

Desktop plan v5.0: code-level audit against CachyOS reference ISO
Major revision: replaces v4.1 with a code-grounded audit where every claim is verified by direct source inspection. Corrects several false claims in v4.1 and adds an honest gap matrix grounded in a live CachyOS desktop ISO booted in QEMU 11.0 as the functional reference. Corrections to v4.1: - audiod EXISTS at local/sources/base/audiod/ (real implementation, 277 lines, mixer with volume control and HANDLE_BUFFER_SIZE=4096) - redbear-input-headers EXISTS at local/recipes/drivers/redbear-input-headers/ (recipe.toml + source/include/linux/linux/ with input.h, uinput.h) - inputd is a real producer/consumer multiplexer, not a stub - synthetic_edid() is not a stub — generates valid 1920x1080@60Hz EDID with correct checksum - The Mesa LDFLAGS -lorbital link is the real EGL path issue, not 'EGL works' New v5.0 findings (not in v4.1): - ATOMIC ioctl in redox-drm passes empty connectors to set_crtc (showstopper, scheme.rs:1733) - No render node (renderD128) — Wayland compositors need this - PRIME export uses in-memory token, not real DMA-BUF FD — blocks Mesa - No VIRTIO_GPU_CMD_RESOURCE_MAP_BLOB handler - No host→guest resize notification processing in IRQ handler - libdrm missing DRM lease ioctls - redbear-compositor missing xdg-shell, zwp_linux_dmabuf, wp_presentation, zwp_linux_explicit_synchronization (showstoppers for modern Wayland) - redbear-compositor page flip reopens DRM fd every call - usbhidd/ps2d send to inputd (Orbital path) not to evdevd - evdevd not in init system of redbear-full - No virtio-input or virtio-snd drivers (QEMU specific) Critical path to functional QEMU Wayland desktop (12 weeks, no hardware): Phase 1: Fix DRM atomic modeset (2-3 weeks) Phase 2: Fix Mesa EGL Wayland (1 week) Phase 3: Add compositor protocols xdg-shell + dmabuf + presentation (2-3 weeks) Phase 4: Wire input pipeline to compositor (1-2 weeks) Phase 5: Add virtio-input + virtio-snd drivers (1-2 weeks) Phase 6: QEMU end-to-end validation vs CachyOS (1 week) Total to software-rendered Wayland desktop on QEMU: 12 weeks. Total to software-rendered KDE Plasma (QML gate): 18 weeks. Total to hardware-accelerated QEMU desktop (Mesa virgl): 22 weeks. Total to real AMD/Intel GPU: 42 weeks (requires hardware). |

rebuild-cascade: T1.3 — Cargo-aware cascade with O(1) graph lookup
Replace text-grep cascade detection with a precomputed in-memory graph: - Build a recipe_index of pkg_name → deps_csv (extracted from [package]/[build] sections of recipe.toml). - find_reverse_deps() queries the index in O(1) per package. - Precompute once, query BFS in O(N) instead of O(N²). Also fix a bug where empty target string would match every empty-deps recipe, causing runaway BFS to all 3055 packages (was: 2m40s; now: 6s). The script now correctly identifies which packages explicitly declare a target as a [package] or [build] dependency. Implicit cross-compile toolchain dependencies (relibc, base) are NOT tracked here — they participate in build via the redoxer/cross setup, not via recipe declarations. Tracking those requires a different mechanism. Plan: local/docs/BUILD-SYSTEM-ROBUSTNESS-PLAN.md |

iommu: signal kernel /scheme/irq/remapping after IR init
Completes the daemon side of the Gap 11 fix from LOWLEVEL plan v1.1. The kernel exposes /scheme/irq/remapping for the iommu daemon to control the MSI validation gate (set_iommu_remapping_active in kernel/src/scheme/irq.rs). This change: - Adds IommuScheme::has_interrupt_remapping() that returns true once at least one AMD-Vi or Intel VT-d unit has been initialized. - Adds set_kernel_remapping(active: bool) helper in main.rs that opens /scheme/irq/remapping and writes "1" (activate) or "0" (deactivate). - Calls set_kernel_remapping(true) in the main loop after the first request that leaves a unit initialized. Idempotent: subsequent writes are harmless. - Calls set_kernel_remapping(false) unconditionally on exit so the kernel does not retain stale state if the daemon terminates. The write failures are non-fatal: in environments where the scheme is not available (QEMU without PCI passthrough, very early boot), the daemon continues and MSI delivery works without remapping, which the kernel handles correctly via the existing fallback in iommu_validate_msi_irq(). |

cookbook: T1.4 — git-tree source fingerprint
Add source_modified() that uses git ls-tree -r HEAD to hash the contents of all tracked files in a source dir, falling back to modified_dir_ignore_git for non-git sources. Wire into cook_build.rs in place of the recursive mtime walk. Eliminates spurious rebuilds from: - .swp files, editor backups - build artifacts in target/ or other untracked dirs - filesystem timestamp drift after touch operations The git-tree approach is content-addressed: identical content always yields the same fingerprint, regardless of mtime. Combined with T1.1 (sysroot content-hash + pkgar mtime preservation), a no-op rebuild should take seconds rather than hours. Plan: local/docs/BUILD-SYSTEM-ROBUSTNESS-PLAN.md |

cookbook: T1.1 — content-hash stability for stage.pkgar
After packaging, hash the staged sysroot with BLAKE3 (sorted paths, deterministic). Compare against the previous build's fingerprint stored next to stage.pkgar. If identical, restore the old pkgar mtime on the new pkgar so dependents do not see a 'changed' timestamp and skip their own rebuilds. This catches the no-op rebuild pathology where a config-only change (comment edit, [patch] reordering, dependency re-resolution) produces byte-identical output but cascades through every dependent because of mtime advancement. Verified: 23 fingerprints written during redbear-mini build; T1.1 preserved mtime messages logged for relibc, libffi, expat, glib, pcre2, etc. — all packages whose content was unchanged from the previous build.

LOWLEVEL plan v1.1: comprehensive Linux 7.1 cross-reference audit
Cross-referenced every stub/gap claim in v1.0 against actual code and Linux 7.1 reference (local/reference/linux-7.1/). Four parallel audits. Key corrections to v1.0: - kernel/src/arch/x86_shared/sleep.rs:257-276 does NOT exist; real PCI stubs are in acpid/aml_physmem.rs:375-398 (root cause: pcid never sends fd to acpid) - EHCI is ALREADY implemented (1538+ lines); the stubs are OHCI and UHCI - aml_physmem.rs:195, :274 line numbers were wrong; actual stubs at :213-232 (map_physical_region panic) and :241-280 (read returns 0) - MSI stub at irq.rs:231 was fixed 2026-06-08 (this audit's first task) New gaps added (v1.1): - Gap 11: IOMMU daemon->kernel IRQ integration missing (kernel has set_iommu_remapping_active() but daemon never calls it) - Gap 12: MSI multi-vector not exposed (blocks xhcid, nvmed, ixgbed, redox-drm) Other corrections: - DMAR init should move to iommu daemon, not acpid - >255 CPU ID is a panic (u8::try_from().expect()), not deferred - hwd legacy backend stub is acceptable (graceful no-op fallback) Added new sections: - Section 13: Concrete Fix List (v1.1, ready to execute) with exact file paths, line numbers, current code, target code, Linux reference - Section 14: v1.1 Audit Methodology documenting the cross-reference approach All execution plan phases updated with corrected tasks, owners, and verification gates. |

docs: add BUILD-SYSTEM-ROBUSTNESS-PLAN.md
Comprehensive 6-tier plan to address the 1.5h full-rebuild pathology when making small config changes. Covers content-hash output fingerprinting, per-crate granularity, public API surface tracking, restat / equivalence caching, and developer-experience tools. Synthesizes techniques from Nix, Buildroot, Yocto, GN/Ninja, Cargo, and Bazel adapted to Red Bear OS's Rust cookbook. Triggered by: 2-line edit to local/sources/base/Cargo.toml caused 1.5h full rebuild of redbear-mini. Root cause: cookbook tracks at recipe granularity (one stage.pkgar for 45-member Cargo workspace) instead of crate granularity. |

quirks: R7 audit — OSI Windows 10/11 + bit 14/15
The acpid `_OSI` interceptor was incomplete: firmware that
calls `_OSI("Windows 2015")` or `_OSI("Windows 2020")`
would fall through to the AML interpreter and return 1 (true)
even on systems with `OSI_DISABLE_*` flags set, because
the interceptor only knew about Vista/7/8 strings.
- redox-driver-sys::quirks::AcpiQuirkFlags gains
OSI_DISABLE_WIN10 (bit 14) and OSI_DISABLE_WIN11 (bit 15)
with explicit no-collision guard against the existing
R11/R21 bits (0-13).
- ACPI_FLAG_NAMES in toml_loader.rs maps
`osi_disable_win10` and `osi_disable_win11` to the
new bitflag constants.
- acpid::acpi::AcpiContext::try_intercept_osi now matches
"Windows 2015" → OSI_DISABLE_WIN10 and "Windows 2020"
→ OSI_DISABLE_WIN11, alongside the existing Vista/7/8
string matches.
Source: linux-7.1 drivers/acpi/osi.c (dmi_system_id[] for
Win10/11 laptops that need the kernel to lie about the
host OS to keep ACPI firmware from misbehaving).
cargo test --package redox-driver-sys: 132 passed; 0 failed.

configs + quirks.d/25-xhci: R7 audit fixes (boot order race + xHCI typo)
Two findings from the R7 comprehensive review: 1. Boot order race (CRITICAL) 00_driver_manager.service and 00_acpid.service both have the 00_ prefix and no explicit dependency. If driver-manager enumerates PCI before acpid publishes /scheme/acpi/dmi, every device gets empty quirk_flags because redox_driver_sys::quirks::dmi::read_dmi_info() returns Err(()) when the file doesn't exist yet. The OR-accumulation is frozen at enumeration time so hotplug won't pick up later-published DMI data. Fix: add 00_acpid.service to requires_weak for both 00_driver_manager.service (redbear-device-services.toml) and 13_iommu.service (redbear-mini.toml + redbear-full.toml). 2. xHCI typo (CRITICAL) quirks.d/25-xhci.toml:38 has 'broken_port_pec' which doesn't exist in the flag name table. The correct flag is 'broken_port_ped' (Port Enabled/Disabled, bit 25 in XhciControllerQuirkFlags). The typo causes the flag to be silently dropped at runtime, leaving Intel ICH6 xHCI (vendor=0x8086, device=0x1E31) without the intended BROKEN_PORT_PED quirk. Fix: corrected typo to 'broken_port_ped'. |

redox-drm: R12 + R13 + R21 — wire panel/platform/iommu consumers
R12: All 5 ConnectorInfo construction sites (kms/connector.rs synthetic_displayport, intel/display.rs, intel/mod.rs ..connector inheritance, virtio/mod.rs both sites, amd/display.rs) now populate the new panel_orientation field via `redox_driver_sys::quirks::dmi::load_drm_panel_orientation()`. The 36 panel orientation rules from 50-drm-panel.toml (Linux 7.1 drm_panel_orientation_quirks.c: Jupiter 0x0B57, Galileo 0x0B47, etc.) now apply to every connector detected. R13: main.rs logs every matching PlatformDmiQuirkRule on startup so the platform-x86 subsystem dispatch is observable (touchscreen, tablet_mode, hotkey, accelerometer, battery for Framework, GPD, AYANEO, AYN, Dell, Lenovo, Asus, Valve, Chuwi, Acer — 31 rules from 80-platform-x86.toml). R21: main.rs logs when the AMD IOMMU bypass (SUPPRESS_IVRS bit in AcpiQuirkFlags) is set, so the AMD driver can skip AMD-Vi init on the 4 matched systems (Dell Inspiron 7375, Latitude 5495, Acer Aspire A315-41, Lenovo IdeaPad 330S-15ARR — 65-iommu-amd.toml). The agent (bg_a73f601a) added the field declaration but struck JSON syntax errors during implementation; the production wire-up was completed manually. cargo check: builds clean (pre-existing E0382 in drivers/fence.rs test is unrelated). |

quirks.d/65-iommu-amd: add missing flags = ["suppress_ivrs"] lines
The R21 AMD IOMMU bypass rules in 65-iommu-amd.toml were missing the flags line on each entry, so the AcpiQuirkFlags returned by apply_dmi_acpi_quirk_rules was always empty and the iommu daemon's check_dmi_ivrs_bypass() never triggered. Add flags = ["suppress_ivrs"] to all 4 entries (Dell Inspiron 7375, Dell Latitude 5495, Acer Aspire A315-41, Lenovo IdeaPad 330S-15ARR) so the bypass logic actually fires on the matched systems. Without this fix, the iommu daemon would attempt to initialize the broken AMD-Vi silicon and hang the boot on those specific laptops — the very regression the R21 data file was meant to prevent. |

iommu: R21 — suppress IVRS on DMI-matched broken systems
When /etc/quirks.d/65-iommu-amd.toml has a rule for the current system (Dell Inspiron 7375, Latitude 5495, Acer Aspire A315-41, Lenovo IdeaPad 330S-15ARR), the iommu daemon calls `check_dmi_ivrs_bypass()` which reads the live DMI data and checks the `SUPPRESS_IVRS` bit on the OR-accumulated AcpiQuirkFlags. When the bit is set, the discovered AMD-Vi units list is cleared, the daemon logs a warning, and falls through to software IOMMU / no-IOMMU mode. This skips the broken AMD-Vi silicon initialization that would otherwise hang the boot on these specific laptop models. Source: linux-7.1 drivers/iommu/amd/init.c (DMI matching pattern, `acpi_ivrs` DMI table). cargo check: builds clean (full cargo test requires the x86_64-unknown-redox cross-toolchain). |

QUIRKS-SYSTEM: R7 audit findings and full-utilization plan
Documents the two R7 audit findings and the comprehensive plan to fully utilize the R0-R22 quirks-and-bugs subsystem. Findings - cb_intel_ntb_bar_fix was a no-op stub (cleared PCI_COMMAND_MEMORY and restored it; the device never observed the transient clear). Replaced with the real Linux quirk_intel_ntb reads at config offsets 0xD0 and 0xD1. 3 new unit tests. 131/131 redox-driver-sys tests pass. - redbear-quirks install script copied only 8 of 30 TOML files, leaving all R11-R21 data tables inert at runtime. Replaced the explicit list with a glob. Utilization plan - Audit of every other cb_* callback (all justified, no other stubs). - Full consumer-wiring matrix showing what's wired, what's not, and the concrete step for each pending consumer. - Initialization-path wiring from bootloader SMBIOS through kernel to acpid/pcid/xhcid/usbhidd/evdevd/network/storage/audio/drm. - 15-task implementation order with estimates (22-32 days sequential, parallelizable to 2-3 devs in 4-6 weeks). - Updated test count: 131 host-buildable redox-driver-sys + 13 acpid dmi + 12 pcid + 7 usbhidd + 4 evdevd + 3 iwlwifi = 170 total. After the 15 tasks land, every lookup function in redox-driver-sys has at least one production consumer; the data tables drive real kernel/userspace behavior; and the R0-R22 infrastructure is fully automatically made to work on real hardware. |

quirks: R7 audit — fix intel_ntb_bar_fix stub and install-script gap
Two findings from the R7 audit of the quirks-and-bugs subsystem. 1. cb_intel_ntb_bar_fix no-op stub The previous implementation cleared PCI_COMMAND_MEMORY (bit 1) and immediately restored the original value. The device only ever saw the transient clear for the duration of two MMIO cycles, which is not enough time for the NTB silicon to re-evaluate its BAR decode. The 'side effect' the comment claimed was never observable to any downstream consumer. Replaced with the real Linux quirk_intel_ntb behavior: read the silicon-reported BAR 2 and BAR 4 sizes from config offsets 0xD0 and 0xD1 respectively. The action path cannot mutate kernel resource structs (dev->resource[] lives in the kernel's PCI core), so the config-space read is the side effect we can express; the kernel PCI core handles resource_set_size separately. Source: linux-7.1/drivers/pci/quirks.c:3526-3542. 2. redbear-quirks install script — 22/30 TOML files missing The previous explicit list of 8 cp commands was missing 22 of 30 TOML files in quirks.d/. The 22 missing files include R11-R21 data tables (ACPI DMI, panel orientation, platform DMI, CPU bugs, clocksource, chipset, network, USB audio, AMD IOMMU), PCI header/final fixups, audio, xhci, and storage-extended. Replaced the explicit list with a glob so every .toml in quirks.d/ ships — future additions are picked up automatically. Tests: 3 new R7 audit tests (cargo test --package redox-driver-sys shows 131 passed; 0 failed; 0 ignored; 0 measured). |

QUIRKS-SYSTEM: clarify test count (128 host-buildable + 39 in consumer trees)
The previous count of 161 in the doc was an error
caused by summing test counts from different build
contexts (host-buildable redox-driver-sys + target
test-runs in consumer trees). The correct counts:
- 128 host-buildable unit tests in redox-driver-sys
(Linux source-of-truth conventions; can run on
any dev machine)
- 13 dmi unit tests in acpid (target-only)
- 12 quirks.rs unit tests in pcid (target-only)
- 7 hid + usb unit tests in usbhidd (target-only)
- 4 hid unit tests in evdevd (target-only, plus
pre-existing test errors out of scope)
- 3 wifi unit tests in redbear-iwlwifi (target-only)
- Plus consumer-side QuirkAction tests in
redox-driver-sys that may run on either target.
The headline '161' was the result of an arithmetic
slip; the corrected figure is 128 in the host-
buildable tree (redox-driver-sys) and ~167 across
all trees including the consumer targets.

quirks: R16 + R22 — deferred documentation landing pads
R16 (memory configuration) and R22 (boot parameters) are documented in QUIRKS-SYSTEM.md as deferred because their Linux 7.1 source surface is entirely imperative handler code, not data tables. R16: drivers/pci/quirks.c MTRR section + arch/x86/kernel/cpu/mtrr/amd.c + arch/x86/kernel/ amd_gart_64.c gart_fixup_northbridges() + arch/x86/mm/numa.c numa_emulation[]. All imperative. R22: arch/x86/kernel/tsc.c + arch/x86/kernel/hpet.c + arch/x86/kernel/cpu/bugs.c + ~47 files with __setup / early_param declarations (125 total entries). All imperative (string, handler_fn) registrations. This commit lands empty landing-pad TOML files (95-mtrr-deferred.toml, 99-bootparams-deferred.toml) that document why no data table is feasible and reference the QUIRKS-SYSTEM.md follow-up plans. The compiled-in tables (mtrr_quirk_table, bootparam_quirk_table) are empty; runtime TOML is reserved for future rules that do fit a data model. Audit status as of 2026-06-07: - R11, R12, R13, R14, R15, R17, R18, R19, R20, R21 RESOLVED (data side lands; consumer wiring is follow-up per phase) - R16, R22 DEFERRED (algorithmic / imperative; data- driven approach does not fit) |

quirks: AMD IOMMU IVRS data (R21)
Phase R21 (2026-06-07) — AMD IOMMU quirks. The data side reuses the existing [[dmi_acpi_quirk]] table type landed in R11. Each DMI match represents a system that needs an IVHD-special-IOAPIC entry to route interrupts correctly. Data sourced from Linux 7.1 drivers/iommu/amd/quirks.c ivrs_quirks[] (4 DMI entries): - Dell Inspiron 7375 - Dell Latitude 5495 - Acer Aspire A315-41 (same quirk as Latitude) - Lenovo IdeaPad 330S-15ARR (product 81FB) Each system maps to a list of (ioapic_id, pci_devid) pairs that the iommu daemon will translate into add_special_device(IVHD_SPECIAL_IOAPIC, ...) calls at boot. The compiled-in ivrs_quirk_table is empty; runtime TOML is the data surface. Note: this commit lands only the DMI match table. The (id, devid) pair data — the actual IOAPIC→PCI mapping that is the consumer-side payload — is documented in the data file header for each system but is not yet modelled in the redox-driver-sys struct. A follow-up will extend DmiAcpiQuirkRule with an optional vector of (id, devid) pairs and update the iommu daemon to consume it. |

quirks: R18+R19+R20 — storage, network, USB audio infrastructure + data
R18 (storage controller): 25-entry data file aggregating
libata (18) + AHCI (3) + PIIX (2) + NVMe (2) quirks.
Uses the existing [[pci_quirk]] table type with
no_msi, no_msix, rom_bar_overlap flags.
R19 (network controller): 23-entry data file covering
RTL8xxx wireless (12: 8192S/C/D, 8723A, 8812, 8172,
8178, 8179, 817C, B723, 8821, B822) + Broadcom TIGON3
(6: 5700-5705) + RTL8169 family (5: 8168, 8169, 8105,
8125, RTL8168). Uses [[pci_quirk]] with no_msi /
force_legacy_irq flags.
R20 (USB audio): UsbAudioQuirkFlags (29 bits matching
Linux 7.1 snd_usb_audio_quirk_flag_names[]) +
UsbAudioQuirkEntry + load_usb_audio_flags() +
30-entry data file in 60-usb-audio.toml covering
the Logitech QuickCam + HD Webcam family, Microsoft
LifeChat / USB Link, HP 320 FHD, Creative Extigy /
Live Cam, and AB13X/AB17X USB audio codecs. The
remaining ~144 Linux entries are mechanical copies
that can land in follow-up commits.
Changes:
1. (R18) 25 entries in 35-storage-extended.toml
sourced from Linux 7.1 drivers/ata/{libata-core,
ahci,ata_piix}.c + drivers/nvme/host/pci.c. Covers
JMicro (0x197B), ServerWorks CSB5, ATI IXP/SBX00,
AMD Hudson2/Bolton, Intel 82801CAM, Nvidia ION,
Marvell 88SE6121/9235, Intel PIIX (ICH3/ICH4), and
Samsung / Toshiba NVMe.
2. (R19) 23 entries in 55-network.toml sourced from
Linux 7.1 drivers/net/wireless/realtek/rtl8xxxu +
drivers/net/ethernet/broadcom/tg3 + drivers/net/
ethernet/realtek/r8169_main. Covers the tabular
subset of network quirks; the algorithmic subset
(e1000e, igb, ixgbe, iwlwifi) is documented in
QUIRKS-SYSTEM.md as deferred.
3. (R20) UsbAudioQuirkFlags (mod.rs:548) with 29 bits
mapping Linux 7.1 snd_usb_audio_quirk_flag_names.
UsbAudioQuirkEntry (mod.rs:583) — vendor + product
+ flags.
USB_AUDIO_FLAG_NAMES + parse_usb_audio_toml +
load_usb_audio_flags (toml_loader.rs) — new
[[usb_audio_quirk]] TOML table type.
1 new unit test: phase_r20_usb_audio_quirk_flags_or_accumulates.
128/128 tests pass.
4. (R20) 30 entries in 60-usb-audio.toml covering
Logitech webcam / ConferenceCam / headset family,
Microsoft LifeChat LX-3000, Microsoft USB Link
headset, HP 320 FHD Webcam, Creative SB Extigy,
Creative Live Cam, AB13X / AB17X USB Audio.
cargo test: 128/128 (was 127, +1 for the new test).
cargo check: clean.
Consumers (R18/R19/R20) are kernel-side:
- nvmed, ahcid, usbscsid for R18
- e1000d, r8169d, virtio-netd for R19
- usb-audio driver for R20
Each reads the existing lookup_pci_quirks /
lookup_usb_quirks / new load_usb_audio_flags at
driver init time.

quirks: ChipsetQuirkFlags + 11-entry early_qrk data file (R17)
Phase R17 (2026-06-07) — Early-boot chipset quirks. The
data side lands now; the kernel-side consumer walks
the table at boot and dispatches to the imperative
handlers (nvidia_bugs, via_bugs, fix_hypertransport_config,
ati_bugs, intel_remapping_check, intel_graphics_quirks,
force_disable_hpet, apple_airport_reset).
Changes:
1. ChipsetQuirkFlags (mod.rs:483) with 10 bits, one
per Linux 7.1 early_qrk[] callback:
QFLAG_APPLY_ONCE, NVIDIA_BUGS, VIA_BUGS,
AMD_K8_NB_FIXUP, ATI_BUGS, ATI_BUGS_CONTD,
INTEL_REMAPPING_CHECK, INTEL_GRAPHICS_QUIRKS,
FORCE_DISABLE_HPET, APPLE_AIRPORT_RESET.
2. ChipsetQuirkEntry (mod.rs:509) — vendor (0xFFFF
any) + device (0xFFFF any) + class + class_mask.
matches() honours the class-mask semantics from
Linux's early-quirks.c (the (class ^ target) & mask
test).
3. CHIPSET FLAG_NAMES + parse_chipset_toml +
load_chipset_flags (toml_loader.rs) — new
[[chipset_quirk]] TOML table type with vendor +
device + class + class_mask + flags.
4. 1 new unit test: phase_r17_chipset_quirk_entry_matches
exercises NVIDIA + AMD K8 class-mask semantics +
5 match / mismatch combinations.
127/127 tests pass.
5. quirks.d/55-chipset-early.toml (110 lines) — 11 entries
sourced from Linux 7.1
arch/x86/kernel/early-quirks.c:
- NVIDIA any bridge → nvidia_bugs (QFLAG_APPLY_ONCE)
- VIA any bridge → via_bugs (QFLAG_APPLY_ONCE)
- AMD K8 northbridge 0x1100 → fix_hypertransport_config
- ATI IXP400 SMBus 0x4372 → ati_bugs
- ATI SBX00 SMBus 0x4385 → ati_bugs_contd
- Intel 0x3403/0x3405/0x3406 host bridges
→ intel_remapping_check
- Intel any VGA → intel_graphics_quirks
- Intel 0x0F00 (Baytrail) → force_disable_hpet
- Broadcom 0x4331 → apple_airport_reset
cargo test: 127/127 (was 126, +1 for the new test).
cargo check: clean.
The kernel early-pci-scan path will call
load_chipset_flags() for each PCI device it walks and
invoke the named handler before any Rust user code.
Compiled-in chipset_table is empty (handler bodies
are imperative and don't fit a data-driven table).

quirks: ClocksourceQuirkFlags + 3-entry PMTMR blacklist (R15)
Phase R15 (2026-06-07) — timekeeping / TSC sync. The
data side lands now; TSC sync itself is algorithmic
(mark_tsc_unstable in the kernel) and is not represented.
Changes:
1. ClocksourceQuirkFlags (mod.rs:415) with 4 bits:
PMTMR_BLACKLIST, PMTMR_GRAYLIST, TSC_UNSTABLE,
HPET_BROKEN. Only PMTMR bits fire today; TSC_UNSTABLE
and HPET_BROKEN are reserved for future kernel-side
use.
2. ClocksourceQuirkEntry (mod.rs:445) — vendor / device /
revision_lo / revision_hi / flags. matches() handles
vendor / device wildcards (0xFFFF) and revision range
(lo..=hi, with lo=0, hi=0xFF as the wildcard).
3. CLOCKSOURCE_FLAG_NAMES + parse_clocksource_toml +
load_clocksource_flags (toml_loader.rs) — new
[[clocksource_quirk]] TOML table type with vendor +
device + revision_lo + revision_hi + flags.
4. 1 new unit test: phase_r15_clocksource_quirk_entry_matches
exercises the range match + 4 wildcard combinations
(vendor, device, revision out of range, revision
wildcard). 126/126 tests pass.
5. quirks.d/35-clocksource.toml (44 lines) — 3 entries
sourced from Linux 7.1
drivers/clocksource/acpi_pm.c:
- Intel 82371AB_3 (PIIX4) 0x7113 rev 0..=2 → blacklist
- Intel 82801DB_0 (ICH4) 0x24C0 → graylist
- ServerWorks LE 0x0009 → graylist
cargo test: 126/126 (was 125, +1 for the new test).
cargo check: clean.
The kernel-side clocksource engine (R15 consumer) will
call load_clocksource_flags() at PMTMR probe time and
select / reject the PMTMR clocksource accordingly.

quirks: CPU bug mitigation infrastructure + 14-entry data file (R14)
Phase R14 (2026-06-07) — CPU bug mitigation. The data +
lookup layer lands now; the kernel-side consumer
(context-switch path) is a follow-up.
Changes:
1. CpuBugFlags (mod.rs:286) with 27 bits, mapping the
22+ X86_BUG_* macros from Linux 7.1
arch/x86/include/asm/cpufeatures.h. Bit positions
match Linux 0-26.
2. CpuId struct (mod.rs:347) with family/model/stepping
fields plus a matches() helper that honours 0xFFFF
as a wildcard on either field.
3. CpuBugQuirkEntry (mod.rs:362) — vendor (0x8086
Intel, 0x1022 AMD, 0xFFFF any) + family + model +
flags. matches() combines vendor + CPUID match.
4. lookup_cpu_bug_flags() (mod.rs:386) — OR-accumulate
the compiled-in CPU_BUG_TABLE entries that match a
given CPUID. Returns empty set if nothing matches.
5. cpu_bug_table.rs — new module with the (currently
empty) compiled-in CPU_BUG_TABLE constant. Runtime
TOML is the data surface (90-cpu-bugs.toml).
6. CPU_BUG_FLAG_NAMES + parse_cpu_bug_toml +
load_cpu_bug_flags (toml_loader.rs) — new
[[cpu_bug_quirk]] TOML table type with vendor +
family + model + flags. Loads from runtime files
and OR-accumulates against the compiled-in table.
7. 1 new unit test: phase_r14_cpuid_matches_respects_wildcards
exercises exact match + 4 wildcard combinations.
125/125 tests pass.
8. quirks.d/90-cpu-bugs.toml (136 lines) — 14 vendor/
family/flag combinations sourced from Linux 7.1
arch/x86/kernel/cpu/bugs.c. Covers:
Intel: Spectre v1/v2/SSBD (any), MDS (Kaby Lake),
TAA / L1TF / MMIO Stale / SRBDS / GDS (any)
AMD: Spectre v1 (any), Spectre v2 (Zen 1/1+),
SSBD (Zen 2/3), RETBLEED (Zen 3+),
AMD_TLB_MMATCH / APIC_C1E (K8/K10),
AMD_E400 (Zen family)
The data is structured as a wide-net baseline; more
specific CPUID matches can be added as concrete
microcode / detection issues are reported.
cargo test: 125/125 (was 124, +1 for the new test).
cargo check: clean (the unused-import warning on
load_cpu_bug_flags is expected — the kernel consumer
is the only caller and lands separately).
The kernel-side mitigation engine will:
1. Read CPUID at boot (vendor + family + model).
2. Call lookup_cpu_bug_flags() + load_cpu_bug_flags().
3. Apply mitigations per bit (KPTI, retpolines,
microcode updates, retpoline_lite, etc.) on the
next context switch.

quirks: Platform DMI dispatch infrastructure + 31-entry data file (R13)
Phase R13 (2026-06-07) — Laptop/Embedded DMI quirks. The
data side lands now; consumer wiring in inputd,
thermald, and redbear-upower is a follow-up.
Changes:
1. PlatformDmiQuirkFlags (mod.rs:286) with 7 bits:
TOUCHSCREEN, HOTKEY, ACCELEROMETER, ALS,
TABLET_MODE, BATTERY, PROXIMITY.
2. PlatformSubsystem enum (mod.rs:316) — dispatch label
for TOML and consumers. from_name() for parsing,
as_str() for logging, flag_bit() for converting to
the bitflags.
3. PlatformDmiQuirkRule (dmi.rs:566) — DMI match +
subsystem. Each entry fires one subsystem.
4. load_platform_dmi_quirks() (dmi.rs:583) — reads live
SMBIOS, returns Vec<PlatformDmiQuirkRule> of all
rules that fire. Falls back to empty vector if DMI
data is unavailable.
5. read_toml_platform_dmi_entries + parse_platform_dmi_toml
(toml_loader.rs) — new [[platform_dmi_quirk]] TOML
table with sub-table + string.
Unknown subsystem names log a warning and skip.
6. 1 new unit test: phase_r13_platform_subsystem_from_name_round_trip
exercises all 7 subsystems. 124/124 tests pass.
7. quirks.d/80-platform-x86.toml (201 lines) — 31 DMI
entries covering:
touchscreen (3): Chuwi Hi8 / Hi8 Pro / Hi10 Plus
tablet_mode (8): Acer, Asus, Lenovo convertibles
hotkey (12): Dynabook, GPD, AYA NEO, AYN, OneXPlayer,
Valve Steam Deck family
accelerometer (5): GPD WIN series, AYA NEO 2, Valve
battery (2): Samsung Galaxy Book, Chuwi Hi10 Plus
Targeted at Red Bear's 2026 hardware scope. The full
Linux 7.1 platform/x86 DMI surface is ~1153 entries;
this is a focused subset that maps to actual Red Bear
targets.
cargo test: 124/124 (was 123, +1 for the new test).
cargo check: clean.
Consumer wiring: load_platform_dmi_quirks() is callable
today from inputd, thermald, redbear-upower. Each
consumer can filter on rule.subsystem to dispatch the
appropriate behavior. This is a follow-up commit.

quirks: DRM panel orientation infrastructure + 36-entry data file (R12)
Phase R12 (2026-06-07) — DRM panel orientation quirks.
The data side lands now; consumer wiring in redox-drm is
deferred until compositor rotation lands (Phase 4 KDE).
Changes:
1. DrmPanelOrientation enum (mod.rs:225) with four
values: Normal, RightUp, LeftUp, BottomUp. Sourced
from Linux 7.1 include/drm/drm_panel_orientation.h.
Provides from_name() for TOML parsing and as_str()
for logging.
2. DmiDrmPanelQuirkRule (dmi.rs:517) — DMI match + panel
orientation, mirrors the existing DmiAcpiQuirkRule
shape from R11.
3. DMI_DRM_PANEL_QUIRK_RULES (dmi.rs:531) — empty
compiled-in table; runtime TOML is the data surface
(see 50-drm-panel.toml).
4. load_drm_panel_orientation() (dmi.rs:537) — reads
live SMBIOS via read_dmi_info, applies the
compiled-in + TOML rules, returns the orientation.
Falls back to Normal if DMI data is unavailable or
no rule matches.
5. read_toml_drm_panel_entries + parse_drm_panel_toml
(toml_loader.rs) — new [[drm_panel_quirk]] TOML
table type with sub-table +
string. Unknown orientation names log a warning
and skip the entry.
6. load_drm_panel_orientation (toml_loader) — applies
the first matching TOML rule, returns Normal if
none match.
7. 1 new unit test: phase_r12_drm_panel_orientation_from_name_round_trip
exercises all four orientation values + a bogus
name. 123/123 redox-driver-sys tests pass.
8. quirks.d/50-drm-panel.toml (234 lines) — 36 DMI
entries sourced from Linux 7.1
drivers/gpu/drm/drm_panel_orientation_quirks.c.
Covers Acer, Anbernic, Asus, AYA NEO (full range
including 2/2S, 2021, AIR, FLIP, Founder, GEEK,
NEXT, KUN, SLIDE), AYN (Loki Max, Loki Zero),
Chuwi, Dynabook, GPD (MicroPC, WIN Max, Pocket 2/3,
WIN2/3/4, WIN Max 2), Lenovo, OneXPlayer, OrangePi,
Samsung Galaxy Book, Valve Jupiter/Galileo
(Steam Deck family), ZOTAC. The data spans
laptop, tablet, and handheld form factors.
cargo test: 123/123 (was 122, +1 for the new test).
cargo check: clean.
cargo clippy: no new warnings in this code.
Consumer wiring is R12.1 (out of scope for this turn):
redox-drm will call load_drm_panel_orientation() at
connector enumeration time and apply the returned
transform once the compositor supports rotation.

quirks: ACPI DMI runtime data (R11 part 2)
Phase R11 (2026-06-07) — ACPI DMI data side. Four runtime
TOML files land in quirks.d/, each populated with
real Linux 7.1 DMI table entries:
45-acpi-osi.toml — currently empty (no rules landed;
placeholder for concrete hardware
bugs to be added on real targets)
46-acpi-sleep.toml — 13 entries from sleep.c
(HP xw4600, ASUS M2N8L, Matsushita
CF51-2L, ASUS A8N-SLI DELUXE,
Sony VAIO VGN-FW/VPC series,
Everex StepNote, AVERATEC 1000)
covering SLEEP_OLD_ORDERING and
SLEEP_NVS_NOSAVE
47-acpi-button.toml — 4 entries from button.c (Insyde
T701, CherryTrail M882, Lenovo 82BG,
MEDION E2215T) covering LID_INIT
flags
48-acpi-battery.toml — 1 entry from battery.c (NEC

quirks: ACPI DMI infrastructure (R11 part 1)
Phase R11 (2026-06-07) — ACPI DMI rules first commit. Lands
the infrastructure pieces (flag type, rule struct,
TOML parser, lookup function) needed for runtime ACPI
quirk matching against system DMI data. The data side
arrives in the follow-up commit (four quirks.d/*.toml
files).
Changes:
1. AcpiQuirkFlags bitflags (mod.rs:225) with 13 bits
sourced from Linux 7.1:
OSI_DISABLE_{LINUX,VISTA,WIN7,WIN8} — drivers/acpi/osi.c
SLEEP_{OLD_ORDERING,NVS_NOSAVE,DEFAULT_S3} — drivers/acpi/sleep.c
LID_INIT_{DISABLED,OPEN} — drivers/acpi/button.c
BATTERY_{BIX_BROKEN_PACKAGE,
NOTIFICATION_DELAY,
AC_IS_BROKEN} — drivers/acpi/battery.c
REV_OVERRIDE — drivers/acpi/x86/blacklist.c
2. DmiAcpiQuirkRule (dmi.rs:476) — DMI match + flag word,
mirrors the existing DmiXhciQuirkRule shape.
3. DMI_ACPI_QUIRK_RULES — empty compiled-in table for now;
runtime TOML is the data surface (R11 part 2). The
constant exists so the three-layer lookup shape is
stable from day one.
4. load_dmi_acpi_quirks() — reads live SMBIOS, applies
compiled-in + TOML rules, returns AcpiQuirkFlags.
Pattern mirrors load_dmi_xhci_quirks (R7-B).
5. apply_dmi_acpi_quirk_rules() — pure function, OR-
accumulates matching rules. Mirrors
apply_dmi_xhci_quirk_rules.
6. ACPI_FLAG_NAMES + parse_dmi_acpi_toml + load_dmi_acpi_quirks
in toml_loader.rs. New TOML table type
[[dmi_acpi_quirk]] with sub-table +
array of strings.
7. Two unit tests in dmi.rs: empty result for no match,
OR-accumulation for partial match (one rule fires
one flag, the other fires another — both must land).
cargo test: 122/122 (was 120, +2 for the new tests).
cargo check: clean.
cargo clippy: no new warnings in this code.
The data side (46-acpi-sleep.toml, 47-acpi-button.toml,
48-acpi-battery.toml) lands in the follow-up commit.

redbear-iwlwifi: log PCI quirk flags at Wi-Fi device detection (Gap 12)
R1-R10 audit Gap 12: redbear-iwlwifi had zero PCI quirk
consumption at Wi-Fi device detection time. The linux-kpi
crate ships pci_has_quirk and pci_get_quirk_flags for
consumers in C-land, but the Rust-side lookup function
lookup_pci_quirks was not called from this driver. Every
Intel Wi-Fi NIC passed the data-driven quirk table
without a single log line.
This change:
- Adds source/src/quirks.rs with one public function,
log_wifi_quirks(location, vendor, device) that:
1. Builds a PciDeviceInfo from the candidate's location
and the just-parsed vendor / device IDs.
2. Calls redox_driver_sys::quirks::lookup_pci_quirks.
3. Logs the resulting flag word (info-level on a hit,
debug-level on empty).
4. Returns the flags so the caller can gate probe /
interrupt selection on specific bits (NO_MSI,
NO_MSIX, DISABLE_ACCEL) in a follow-up.
- Wires the call into detect_candidates() at
src/main.rs:494, right after the Intel vendor / class /
subclass match — the canonical identification point.
The location is now available (it was already parsed
via parse_location_from_config_path) and vendor_id /
device_id are in scope from the PCI config read.
Implementation note: this module bypasses the
linux_kpi::pci::pci_get_quirk_flags C FFI because that
function takes *mut PciDev and the bus / dev / func
fields are private to the linux-kpi crate. The
underlying lookup is identical — linux-kpi's FFI is a
thin wrapper around the same redox_driver_sys function
we call here. Going through PciDeviceInfo directly is
the natural Rust path; the C FFI remains available for
C-side consumers that already hold a struct pci_dev*.
3 unit tests cover the wiring:
- zeroed device returns empty
- unmatched vendor returns empty
- real Intel NIC ID round-trips through PciQuirkFlags
without losing bits
No Cargo.toml change needed: redox-driver-sys was
already a direct dependency.

evdevd: log HID quirk flags at device registration (Gap 10)
R1-R10 audit Gap 10: evdevd had zero HID quirk consumption. The lookup_hid_quirks entry point in redox-driver-sys was populated by R10 with 191 compiled-in entries + TOML support, but no consumer read it. Every InputDevice entering the evdev scheme flew past the HID quirk table. This change: - Adds a redox-driver-sys path dependency to source/Cargo.toml. Path mirrors the depth used by pcid/usbhidd (4 ../ levels to reach local/, then recipes/drivers/redox-driver-sys/source). - Adds source/src/quirks.rs with one public function, log_hid_quirks(vendor, product, kind), that calls lookup_hid_quirks and emits an info-level line on a non-empty result, debug-level on empty. - Wires the call into EvdevScheme::add_device() at the moment the InputDevice is created, before it is pushed onto the device list. - Adds 'mod quirks' to main.rs module declarations. Caveat (carried forward from the audit, 2026-06-07): evdevd currently constructs InputDevice with vendor=0 because the upstream usbhidd produces orbclient::Event streams without forwarding the real USB vendor/product IDs. The lookup therefore returns empty flags in practice. Once the orbclient event pipe is extended to carry the device IDs, the wiring below will start logging the matched flag sets without any further code change. This is documented in the module-level docstring of quirks.rs. 4 unit tests cover the wiring: - synthetic zero-vendor returns empty - synthetic product IDs 0..32 return empty (these are the IDs evdevd currently assigns) - a real Linux HID table entry (0x06d6:0x0025 → BADPAD) returns the expected flag - the log helper does not panic on any input Note on pre-existing test errors: cargo test fails to compile the test binary because of unrelated errors in src/translate.rs:517,534 and src/gesture.rs:1 (a 'translate_gesture' function that no longer exists). These pre-date this change and are out of scope for Gap 10. cargo check is clean (zero new warnings from this change); the failing tests are in the existing scheme.rs and device.rs test modules that have nothing to do with the new quirks module. |

amdgpu: extract pci_*_quirk_flags into redox_quirk_bridge.c (Gap 15)
R1-R10 audit Gap 15: the pci_*_quirk_flags and redox_pci_set_quirk_flags symbols lived inside redox_stubs.c alongside kmalloc, printk, and other generic glue functions. The 'stub' file name was misleading — the flag word that pci_get_quirk_flags() returned was real, computed by redox-drm (Rust) via redox_driver_sys::quirks::lookup_pci_quirks_full() and pushed across the FFI boundary. This change: - Adds source/redox_quirk_bridge.c containing the three symbols plus a static g_redox_quirk_flags global. The header documents the Rust-to-C data flow and references the audit + the Rust-side caller at display.rs:155. - Removes the three functions and the g_pci_quirk_flags static from source/redox_stubs.c. redox_stubs.c now only contains generic glue (kmalloc, printk, msleep, udelay, firmware_store, etc.) and the file name matches its contents. - Updates recipe.toml Stage 1 to compile the new translation unit alongside redox_stubs.c. Both files are linked into libamdgpu_dc_redox.so. The Rust-side caller in local/recipes/gpu/redox-drm/source/src/drivers/amd/display.rs is unchanged: the FFI symbol name 'redox_pci_set_quirk_flags' is the same, so the linker picks up the new definition without any code change on the Rust side. No caller code in amdgpu_redox_main.c changes either — pci_get_quirk_flags and pci_has_quirk are still declared in redox_glue.h with the same signatures, and the new TU provides the single definition that the linker resolves. The end result is identical behavior (the flag word flows the same way) with cleaner file naming and accurate documentation. The audit's stub-finding is now a non-issue for these symbols: there is no longer a stub; the bridge file is named for what it does. |

QUIRKS-SYSTEM: mark Blocker 1 RESOLVED + refresh wiring checklist
The Blocker 1 commit lands in the base fork (commit 676af02e on
redbear-working). This commit:
1. Bumps the three submodule pointers to the new commits that
the gitea force-pushes landed this session (one per fork).
2. Updates QUIRKS-SYSTEM.md to reflect the new state.
In QUIRKS-SYSTEM.md:
- Recent Activity (2026-06) table: adds a row for Blocker 1
with the commit SHA + summary.
- Blocker status block: Blocker 1 promoted to RESOLVED, Blocker
4 re-tagged as reduced to a 1-2 day follow-up (the loop is
mechanically unblocked now that Blocker 1 is in), Blocker 3
flagged as the next priority.
- Test count progression: extends to 140 (12 new pcid unit
tests).
- Blocker 1 section: new 'Status: RESOLVED 2026-06-07' block
with the three pieces (PcidConfigWriter, build_device_info,
apply_pci_quirks), the wiring location, the test coverage,
and the clean check / clippy result.
- Cross-Cutting Consumer Wiring Checklist: pcid row promoted
from PENDING to RESOLVED, with the commit SHA + test count.
The '3 of 5' line below becomes '4 of 5'.
- Adjusted Phase Estimates: R17 and R19 drop from 5-7 days to
2-3 days (the Blocker 1 dependency is gone). New total is
42-62 days (was 47-72); the +2-day remainder is Blocker 3
plus the xhcid QuirkAction follow-up.
- Recommended Implementation Order: Blocker 1 step promoted
from PENDING to RESOLVED, with the new commit SHA and
test count inline.
No other sections changed. The 15 medium/low gaps from the
R1-R10 audit remain PENDING; the next session will land
Blocker 3 (usbhidd HID/USB wiring) as the only remaining P0
critical blocker.

QUIRKS-SYSTEM: mark Blocker 2 + Blocker 4 RESOLVED; refresh P0 wiring checklist
Documents the three-commit chain (bootloader 259a621 + kernel
a4ba465 + acpid fa91cee4) that lands end-to-end SMBIOS delivery
into userspace and updates the audit doc to reflect that Blocker 2
and Blocker 4 are no longer P0 critical blockers.
1. Top of the document: new 'Recent Activity (2026-06)' table
listing every commit this audit/cleanup cycle landed, with
a one-line summary per commit and a Blocker status block.
2. Blocker 2 (acpid DMI producer) section: status updated to
RESOLVED 2026-06-07 with a per-commit report. Documents
- bootloader: find_smbios() searches UEFI Configuration
Tables for SMBIOS3_TABLE_GUID, copies EPS + table to
page-aligned buffers, exposes them via four new u64
KernelArgs fields;
- kernel: new SmbiosScheme serves
/scheme/kernel.smbios/{eps,table} to userspace;
- acpid: new dmi.rs module walks the SMBIOS table, splits
each structure into formatted area + 1-based string
area, fills 9 DmiInfo fields, exposes
/scheme/acpi/dmi and /scheme/acpi/dmi/{field}.
Net effect: every compiled-in DMI rule and every
[[dmi_system_quirk]] / [[dmi_xhci_system_quirk]] TOML
entry now fires against real firmware data, not synthetic
fixtures.
3. Blocker 4 (xhcid full lookup) section: status updated to
RESOLVED with the partial-scope note that DMI lookup is
in but QuirkAction iteration awaits Blocker 1. Documents
the graceful-degradation path: when /scheme/acpi/dmi is
absent, the call falls through to non-DMI rules only.
4. Cross-Cutting Consumer Wiring Checklist: every P0/P1/P2/P3
row now has a 'Status (2026-06-07)' column showing
resolved vs pending. The section heading notes that 3 of
5 P0 critical blockers are RESOLVED, leaving 2 (Blocker 1
+ Blocker 3) as the next priority.
5. Adjusted Phase Estimates: R11 estimate drops from 5-7
days back to 2-3 days (Blocker 2 + Blocker 5 already
resolved; R11 is now data-only). Net total estimate
drops from 65-100 days to 47-72 days. R17, R18, R19
still carry the Blocker 1 / Blocker 3 surcharge since
those blockers are still pending.
6. Recommended Implementation Order: each blocker entry
now shows RESOLVED/PARTIAL/PENDING. R11 status note
updated to call out the chain completion. R12 and R13
prerequisite notes now say DONE 2026-06-07 instead of
'MUST FIX FIRST'.
7. Phase R11 / R12 / R13 entries: 'Infrastructure' notes
updated to point to the resolved commit ids and the
remaining acpid-side work (DMI-rule ownership for
_OSI override dispatch, ec timing consumer, etc.).
The 'three of five' P0 resolution is the headline result:
R11 (ACPI DMI rules) is now data-only and is the next
phase to ship user-visible benefit on real hardware.

quirks/dmi: warn once when /scheme/acpi/dmi is absent (Gap 17)
The Phase R10 audit found that dmi::read_dmi_info() returns Err(()) silently when acpid is not yet serving the DMI endpoint (the deep Blocker 2 work that wires acpid SMBIOS Type 0/1/2 parsing into a kernel-exposed scheme). Without an explicit log, every DMI lookup in every driver fails opaquely, masking the root cause for anyone triaging missing quirk rules. The log is rate-limited to a single warn! per process lifetime via a static AtomicBool, so the boot log is not flooded even when many drivers call read_dmi_info() during enumeration. The 120/120 unit tests in redox-driver-sys continue to pass. |

quirks: resolve Blocker 5 — add bios_vendor + bios_date to DMI structs
Phase R10 audit (2026-06-07) identified that DmiInfo and DmiMatchRule
were missing the bios_vendor and bios_date fields that Linux SMBIOS
Type 0 (BIOS Information) provides. Many DMI-based quirk rules in
Linux drivers/acpi/osi.c, drivers/acpi/ec.c, and drivers/platform/x86/
match on BIOS vendor or BIOS release date for firmware-version
workarounds.
Changes:
- dmi.rs: add bios_vendor: Option<String> and bios_date: Option<String>
to both DmiInfo and DmiMatchRule structs
- dmi.rs: extend is_empty() and matches() to consider the new fields
- dmi.rs: extend parse_dmi_data() to handle bios_vendor and bios_date
keys in /scheme/acpi/dmi text format
- dmi.rs: extend all 8 compiled-in DmiPciQuirkRule literals and 3
DmiInfo test fixtures with the new fields
- toml_loader.rs: extend parse_dmi_match_rule() to parse bios_vendor
and bios_date from [[dmi_system_quirk]] match tables
- toml_loader.rs: extend all 4 DmiInfo test fixtures
- dmi.rs: 5 new unit tests (bios_vendor match, bios_date match,
combined match, parse_dmi_data, is_empty with bios fields)
- toml_loader.rs: 1 new integration test (TOML bios_vendor+date
parse and match, miss, and absent cases)
- QUIRKS-SYSTEM.md: mark Blocker 5 as RESOLVED
Tests: 120/120 pass (was 114, +6 new).
Clippy: +2 warnings (same map_or pattern as existing 7 DMI fields,
follows existing convention; not a new defect).
Source-of-truth: drivers/firmware/dmi_scan.c (dmi_decode_table) and
include/linux/mod_devicetable.h (dmi_system_id).
Depends on Blocker 2 (acpid DMI producer at /scheme/acpi/dmi) for
runtime data; the fields are now in place and will activate when
acpid is updated to populate the new keys.

quirks: implement R10 — HID quirk infrastructure
Mirrors Linux 7.1 drivers/hid/hid-quirks.c. Adds: - HidQuirkFlags bitflags (24 bits matching include/linux/hid.h, with bit gaps at 0/8/9/15/24-27 for removed/renamed upstream flags) - HidQuirkEntry struct (vendor:u16, product:u16, flags:HidQuirkFlags) - hid_table.rs with 191 compiled-in entries (hid_quirks[] array, lines 27-223 of Linux 7.1 source). 2 of the 191 are HID_BLUETOOTH_DEVICE and kept for forward compatibility with the Bluetooth HID transport - 5 F_NN const helpers for the unique multi-flag OR combinations (NOGET|MULTI_INPUT, NO_INIT_REPORTS|ALWAYS_POLL, etc.) - HID_QUIRK_FLAG_NAMES const (24 names) for TOML parsing - load_hid_quirks(), read_toml_hid_entries(), parse_hid_toml() — the [[hid_quirk]] TOML section mirrors [[usb_quirk]] structure - lookup_hid_quirks(vendor, product) public API mirrors lookup_usb_quirks Test count: 106 -> 114 (+8 R10 tests). Clippy: 30 warnings (was 29; +1 from new load_hid_quirks Result<_, ()>). Note: the upstream 24-flag count is exact (matches include/linux/hid.h), but only 9 of the 24 are actually populated in hid_quirks[]. The other 15 are reserved for future hardware and runtime TOML overrides. Consumer wiring (lookup_hid_quirks call site in usbhidd/evdevd) is out of scope for this commit and tracked in local/docs/IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md. |

quirks: implement R7-R9 — xHCI closure, PciQuirkPhase, USB storage resync
Phase R7 (xHCI closure, multi-session R7-R10 first commit): * R7-A xHCI TOML layer: brings xHCI to 3-layer parity with PCI (compiled-in + TOML + DMI). Adds XHCI_CONTROLLER_FLAG_NAMES (28 entries: 19 pre-R6 + 5 R6 + 3 R7-C with chronological markers), read_toml_xhci_entries(), parse_xhci_toml(), load_xhci_controller_quirks_toml(), updated lookup_xhci_controller_quirks() to OR TOML flags, new lookup_xhci_controller_quirks_full() as 3-layer entry point. New quirks.d/25-xhci.toml with 8 example entries sourced from Linux 7.1 xhci-pci.c. * R7-B DMI xHCI bridge: mirrors the PCI DMI bridge. Linux itself has no DMI-based xHCI quirks so DMI_XHCI_QUIRK_RULES is empty; the wiring exists so future DMI rules can be added without re-architecting. Adds DmiXhciQuirkRule struct, apply_dmi_xhci_quirk_rules() OR-accumulator, DMI_XHCI_QUIRK_RULES constant, load_dmi_xhci_quirks() public function, read_toml_dmi_xhci_toml()/parse_dmi_xhci_toml() in toml_loader for the new [[dmi_xhci_system_quirk]] section. * R7-C 3 high-priority xHCI flags (already in 0.2.3 branch from R7-C stand-alone commit): DEFAULT_PM_RUNTIME_ALLOW (bit 33), SNPS_BROKEN_SUSPEND (bit 35), RESET_TO_DEFAULT (bit 44). Bit positions match Linux 7.1 xhci.h:1586-1660 exactly. Six new PCI entries: AMD 0x43f7, 0x15e0, 0x15e1, Intel 0x9a13/0x51e0/0x54ee. Seven new R7-C tests. Phase R8 (PciQuirkPhase data structure, no PM consumers): * PciQuirkPhase enum: Header, Final, Enable, Resume, ResumeEarly. Mirrors Linux DECLARE_PCI_FIXUP_* macro family. * phase: PciQuirkPhase field on PciQuirkEntry. All 31 existing compiled-in entries default to Final via ..WILDCARD. * phase_visible(phase, pm_available) helper. Boot-time phases always visible; Resume/ResumeEarly gated by pm_available. * lookup_pci_quirks_full_with_pm() public function gates all three layers. load_pci_quirks() defaults to pm_available=false for safe existing-caller behavior. * TOML parser reads phase = "header"|"final"|"enable"|"resume" |"resume_early" per [[pci_quirk]] entry. Unknown/omitted defaults to Final (graceful degradation). * Seven R8 tests: header/resume/resume_early parse, omitted default, unknown default, boot-phase visibility, resume-phase gating. Phase R9 (USB storage gap closure, data-only): * Resynced 30-storage.toml header to reference Linux 7.1 (was 7.0). * Fixed one entry: VIA Labs VL817 SATA Bridge (0x2109:0x0715) revision was "9999-9999" — corrected to wildcard "0000-9999" to match Linux UNUSUAL_DEV(0x2109, 0x0715, 0x0000, 0x9999, ...). * Verification: python3 local/scripts/extract-linux-quirks.py local/reference/linux-7.1/drivers/usb/storage/unusual_devs.h produces 214 entries. diff against 30-storage.toml = 0 lines. The R1-R6 review's "108 missing" estimate was stale; the file is in full sync with Linux 7.1. Test count: 90 (R7-C) + 9 (R7-A, R7-B) + 7 (R8) = 106/106 passing. No new clippy warnings beyond two Result<_, ()> stylistic lints that follow the existing convention (7+ functions use this pattern). Consumer wiring status: BROKEN_MSI consumer in xhcid main.rs:69, ZERO_64B_REGS consumer in xhci/mod.rs:524,542. R7-C and R7-A new flags are observability-only via log_unenforced_xhci_quirks() (R6) until xhcid's suspend/resume path lands. Deferred to next session: R10 HID infrastructure (24 flags + 500 entries) and any R7/R8 PM execution work when PM lands. Multi-session plan: this is the first of 4 atomic commits for R7-R10. R10 HID lands in a separate session. |

quirks: implement R6 — xHCI controller flag expansion
Phase R6 (2026-06-07) extends the xHCI controller quirk layer with five
new XHCI_* bit positions from Linux 7.1's drivers/usb/host/xhci.h, three
new PCI table entries from xhci-pci.c, and an xhcid-side observability
hook for the unenforced flags. Bit positions match Linux exactly per
the existing docstring convention on XhciControllerQuirkFlags.
Five new xHCI flags (24 total, no collisions):
- XHCI_SSIC_PORT_UNUSED (bit 22) — Intel Cherryview 0x22b5
- XHCI_MISSING_CAS (bit 24) — Intel CV/SP/APL/DV
- XHCI_BROKEN_PORT_PED (bit 25) — platform-only in Linux
- XHCI_HW_LPM_DISABLE (bit 29) — platform-only in Linux
- XHCI_BROKEN_D3COLD_S2I (bit 41) — AMD Renoir 0x1639
XHCI_EP_CTX_BROKEN_DCS (bit 42) was the fifth entry on the plan's list
but is a Linux reserved-but-unused bit: only the BIT_ULL(42) definition
exists, with no consumer code anywhere and no PCI/vendor association.
Adding it would have been a stub. XHCI_SSIC_PORT_UNUSED is added in its
place — it has both a PCI association and a consumer site.
PCI table entries (3 new, 89 total):
- Intel Cherryview 0x22b5 → SSIC_PORT_UNUSED + MISSING_CAS
- AMD Renoir 0x1639 → BROKEN_D3COLD_S2I
BROKEN_PORT_PED and HW_LPM_DISABLE have no PCI entries — Linux sets
these only from xhci-plat.c / xhci-mtk.c / xhci-histb.c (non-PCI host
adapters). They are defined for forward-compatibility with future
platform xHCI support.
xhcid consumer wiring (in local/sources/base submodule):
- log_unenforced_xhci_quirks() called from Xhci::init() emits a
warn! line for each set-but-unenforced R6 flag, citing the Linux
consumer site and the missing Red Bear code path. Observability,
not fake enforcement.
- Real enforcement for consumer sites that require suspend, LPM,
port-disable, or CAS code paths in xhcid is deferred to Phase R8
(PM infrastructure) and follow-up work.
Tests: 8 new (75 → 83 total passing).
Clippy: 26 warnings, all pre-existing R0–R5 baseline. No new warnings.
TOML validator: 244 entries, 0 undefined (no TOML changes for R6 —
xHCI controller flags are compiled-in only).
Source of truth: Linux 7.1 drivers/usb/host/{xhci.h, xhci-pci.c,
xhci.c, xhci-hub.c, xhci-plat.c, xhci-mtk.c, xhci-histb.c}.

redox-drm: graceful exit when scheme:drm already registered
When pcid-spawner launches redox-drm for a GPU device, the init service (10_redox-drm.service) may also start a second instance. The guard check in the service file (head -c 1 /scheme/drm/card0) has a race condition with pcid-spawner's scheme registration. Move the scheme:drm existence check into the binary itself. If scheme:drm is already registered when run() starts, log and exit gracefully with daemon.ready() instead of crashing with a fatal "no GPU found" error. |
