lg-gram-16z90tp: Phase 0 — collision fixes, quirks pipeline, firmware tables
...
Host: LG Gram 16Z90TP-G.AL89C (Arrow Lake-H, Core Ultra 7 255H).
Plan: local/docs/LG-GRAM-16Z90TP-COMPATIBILITY-PLAN.md
- drivers.d: scope e1000d + rtl8168d matches to subclass 0 (Ethernet);
the vendor+class wildcard also claimed Intel/Realtek Wi-Fi (subclass
0x80) and collided with redbear-iwlwifi (e.g. BE201 8086:7740)
- xhci_table: add universal SPURIOUS_SUCCESS rule for hci_version > 0x96
(Linux xhci.c:5477); LG Gram 8086:7ec0/777d now get exactly Linux's
flag set (0x200009810); flag-parity test added
- quirks: repair system-quirk pipeline — dmi_system_quirk entries with
flags like force_s2idle silently parsed to empty sets. Add
SystemQuirkFlags (4 flags), DmiSystemQuirkRule, dual-namespace TOML
parsing, quirks::system_quirks() consumer API, and the LG 16Z90TP
DMI anchor (board_name match)
- firmware: iwlwifi candidate tables prefer the c-prefixed iwlmld
series (c106..c101) for BE201/CNVi; gf-a0 capped at 100 per
host/linux-firmware evidence; fallback chains updated
- firmware-loader: map flat iwlwifi-* requests into the post-2026
linux-firmware intel/iwlwifi/ layout (builtins + TOML fallbacks)
Tests: redox-driver-sys 72, firmware-loader 11, redbear-iwlwifi 8,
redbear-wifictl 21 all pass; all four components cook for
x86_64-unknown-redox; make lint-config clean.

docs: USB/quirks/low-level doc consolidation + P2-C recovery completion
...
Documentation pass (staleness audit across 5 docs):
USB-IMPLEMENTATION-PLAN.md:
- P2-A marked COMPLETE (canonical 51-flag table in redox-driver-sys,
~85 entries, real HCIVERSION reads, BROKEN_MSI pre-gate)
- P2-C marked CORE COMPLETE: full 36-code recovery matrix documented
(maybe_recover_transfer_error scheme.rs:559-925) with Linux xhci-ring.c
equivalences, restart_endpoint bug fixes, known simplifications, and
remaining P8-C injection-test scope
- Gap table corrected (quirks done, error recovery core done, PM substrate)
- P7-A corrected: HLC lives in Supported Protocol capability port_info
DWORD, NOT HCCPARAMS1 (driver bug fixed in P2-B)
- §12 rewritten: runbook is live v3, not archived; lineage consolidated
IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md:
- xHCI section rewritten: 'restored' -> hardened/gated (BROKEN_MSI
pre-gate, quirk convergence, real HCIVERSION, handle/method agreement)
- Priority 6 refocused from 'keep path healthy' to runtime validation
(BROKEN_MSI controller proof, event-ring under sustained load)
- 26 stale recipes/core/*/source paths -> local/sources/* fork paths
- duplicate ACPI-IMPROVEMENT-PLAN.md reference removed
- xhcid evidence class upgraded to quirk-hardened
- USB plan cross-reference added (feature ownership boundary)
QUIRKS-AUDIT.md:
- xHCI tombstone removed: lookup_xhci_controller_quirks_full is now a
real implementation over XHCI_QUIRK_TABLE (was stub returning empty())
- 'broken TOML mappings' section marked RESOLVED (all 4 flag names now
in PCI_FLAG_NAMES)
- Implementation-status section re-assessed: xhcid consumes 51-flag
XhciControllerQuirkFlags in ~40 paths (was: only PciQuirkFlags)
- test inventory +38 xhci_table.rs tests
QUIRKS-SYSTEM.md:
- xhci_table.rs added to compiled-in tables inventory and file layout
- implementation status: canonical xHCI table row added (P2-A)
- driver consumption: xhcid xHCI-controller-path flag list documented
QUIRKS-IMPROVEMENT-PLAN.md:
- Task 3.1 (USB device quirks in xhcid) marked DONE (13 flags consumed)
- exit criteria 3/4/5/7 marked met; deliverables 1/3/4 completed
- reassessment summary updated for XhciControllerQuirkFlags consumption
Also: chmod +x test-xhci-irq-qemu.sh, test-msix-qemu.sh,
test-usb-storage-qemu.sh (were non-executable).
