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.

|
||||
|
||||

|
||||
**Status:** Planning — no implementation started
|
||||

|
||||
## 2. Device-by-Device Support Matrix (dmesg vs. codebase recon)
|
||||
|
||||
Legend: ✅ = expected to work today (code match + mature path) · 🟡 = code exists, gap or unproven · ❌ = no support
|
||||
|
||||
| Device | ID | Red Bear component | Verdict | Evidence |
|
||||
|---|---|---|---|---|
|
||||
| UEFI boot | — | bootloader fork | ✅ | Standard Phoenix UEFI 2.7; boot proven on AMD/Intel bare metal |
|
||||
| CPU/SMP | 0x6/0xC5 | kernel x2APIC dual-path | ✅ | `local_apic.rs` x2 via CPUID; 16-core boot expected |
|
||||
| HPET | — | kernel | ✅ (n/a) | Redox uses LAPIC/TSC timers; HPET-dysfunctional quirk harmless |
|
||||
| NVMe | 1c5c:1959 | `nvmed` (class 1/8) | ✅ | Class-based match; initfs-capable |
|
||||
| xHCI ×2 | 8086:7ec0, 8086:777d | `xhcid` | ✅→🟡 | Class match 0x0C/0x03/0x30 + Intel baseline quirks; 7ec0 (USB4-adjacent) has no specific quirk entry; unvalidated on HW |
|
||||
| PS/2 keyboard | i8042 | kernel `serio` + `ps2d` | ✅ | AUX-disabled handled (`test_aux_port` → `SECOND_DISABLED`); QEMU + BM proven |
|
||||
| VESA console | — | `vesad`+`fbcond` | ✅ | Boot framebuffer path, always present |
|
||||
| iGPU | 8086:7d51 | `redox-drm` Intel | 🟡 | 0x7D51 **is** in `INTEL_GEN12_MTL_IDS`; but display init assumes Gen8-era register layout; DMC preload gated but **never loaded to HW**; no GuC/HuC |
|
||||
| Legacy iGPU fb | 8086:7d51 | `ihdgd` | 🟡 | Also claims 0x7D51 — priority vs redox-drm must be enforced |
|
||||
| Wi-Fi BE201 | 8086:7740 | `redbear-iwlwifi` | 🟡→❌ | ID in table, fw family correct (`bz-b0-fm-c0`), **but** Mini-MVM is iwlmvm-era and BE201 needs **iwlmld**; fw API 102 vs expected 92–100; zero HW validation |
|
||||
| BT | 8087:0037 | `redbear-btusb` | 🟡 | Recipe exists (bounded BLE slice); Intel bootload/fw-load (sfi+ddc) untested |
|
||||
| Audio HDA | 8086:7728 | `ihdad` | ❌ (arch) | Class-matched and will probe, but cAVS/SOF platform — legacy HDA cannot reach ALC298 behind the DSP; needs SOF port |
|
||||
| USB audio (dongle) | — | `redbear-usbaudiod` | ✅ (interim) | UAC1 full impl; viable interim audio |
|
||||
| Touchpad | 04CA:00CC | `intel-lpss-i2cd`/`dw-acpi-i2cd` + `i2c-hidd` | 🟡 | Chain compiles; controller ACPI HID likely **not in any SUPPORTED_IDS**; no BM validation; single-touch parsing only |
|
||||
| I2C controllers | 8086:7778/7779 | same | 🟡 | ACPI-HID matching may miss Arrow Lake HIDs; PCI-ID fallback matching absent |
|
||||
| Camera | 30c9:00f2 | — | ❌ | No UVC driver anywhere |
|
||||
| Battery/AC | BAT0/ADP1 | `acpid` AML `_BST`/`_PSR` | 🟡 | Polling works; **no event notifications** (no GPE) |
|
||||
| Lid/buttons | PNP0C0D/C/E | — | ❌ | Zero lid code; button GPE re-enable documented as caller's job |
|
||||
| GPE/EC events | GPE 0x6e | `acpid`/`ec.rs` | ❌ | EC byte protocol exists; no GPE dispatch, no QR_EC loop |
|
||||
| Thermal zones | TZ00 | `acpid`+`thermald` | 🟡 | `_TMP`/`_PSV`/`_CRT` + passive cooling via cpufreq works; fan is soft-model only |
|
||||
| CPU freq | ARL-H | `cpufreqd` HWP/EPP | ✅ | Code explicitly notes Arrow Lake-H HWP; MSR path generic |
|
||||
| CPU temp/RAPL | — | `coretempd`, `redbear-power` | ✅ | MSR 0x19C/0x1A2/0x606+; no model gating needed |
|
||||
| Suspend | S0ix/LPIT | `acpid` s2idle | 🟡→❌ | Prep sequence exists; **no LPIT parser, MWAIT loop unwired, no _PRW wake mgmt**; S3 absent on this host |
|
||||
| Shutdown/reboot | S5/reset | `acpid`/kernel | ✅ | Implemented; robustness tracked in ACPI-IMPROVEMENT-PLAN |
|
||||
| IOMMU (VT-d) | DMAR | `iommu` daemon | ✅ (safe no-op) | AMD-Vi only; detects DMAR, logs, registers empty scheme; **do not set REDBEAR_DMAR_INIT=1** (gl_sts hang risk) |
|
||||
| LPC/SMBus/SPI/UART/MEI/GNA/VPU/PMC/ISH/TPM | various | — | ❌ | No drivers; none are boot-critical |
|
||||
| LG WMI hotkeys | — | — | ❌ | No WMI subsystem |
|
||||
| USB-C eth dongle (interim net) | — | `redbear-ecmd` | ✅ (interim) | CDC-ECM driver exists — **only viable interim network path** (no wired NIC on host) |
|
||||
|
||||
### 2.1 Critical config-level defect found during recon
|
||||
|
||||
**e1000d wildcard collision.** `local/config/drivers.d/10-network.toml` matches
|
||||
`vendor=0x8086 class=2` with no subclass filter → on this host it would claim the
|
||||
BE201 Wi-Fi (class 0x02 subclass 0x80) and collide with `redbear-iwlwifi`.
|
||||
The pcid-side `e1000d/config.toml` whitelist is correct; the driver-manager entry
|
||||
is too broad. **Must fix (Phase 0) — add `subclass = 0x00`.**
|
||||
|
||||
### 2.2 Known non-issues (verified, do not re-investigate)
|
||||
|
||||
- VT-d force-enabled: harmless — `iommu` daemon is a clean no-op on DMAR-only machines.
|
||||
- HPET dysfunctional: kernel timers don't need HPET.
|
||||
- AUX port disabled: `ps2d` handles it.
|
||||
- PCI root ports/LPC/host bridge: bus-layer devices, no userspace driver needed by design.
|
||||
- x2APIC: fully supported; IRQ remapping absence does not block MSI/MSI-X delivery.

## 3. Boot Path Analysis (redbear-mini on this host)
|
||||
|
||||
```
|
||||
UEFI 2.7 (Phoenix) → Red Bear bootloader (✅ expected)
|
||||
→ kernel: x2APIC detect (✅), 16-core SMP (✅), MADT (✅), MCFG ECAM 0xC0000000 (✅)
|
||||
→ initfs: pcid → nvmed (✅ SK Hynix) → rootfs mount (✅)
|
||||
→ vesad + fbcond console (✅)
|
||||
→ pcid-spawner + driver-manager:
|
||||
xhcid ×2 (✅ class match, Intel baseline quirks — watch 7ec0)
|
||||
ps2d (✅)
|
||||
ihdad (🟡 probes, finds no usable codec — must fail gracefully, not hang)
|
||||
redbear-iwlwifi (🟡 probes, fw API mismatch likely — must fail gracefully)
|
||||
e1000d (❌ COLLISION — Phase 0 fix)
|
||||
→ acpid: RSDP/FADT/DSDT/SSDT/EC (✅), battery/AC poll (🟡), shutdown (✅)
|
||||
→ cpufreqd HWP (✅), coretempd (✅), thermald (🟡)
|
||||
→ login prompt (✅ expected) — redbear-mini usable with keyboard + USB-Ethernet dongle
|
||||
```
|
||||
|
||||
Expected first-boot result: **boots to login on VESA console with working keyboard,
|
||||
NVMe, USB, CPU power management, battery readout, and shutdown — but no touchpad,
|
||||
no network (without USB dongle), no DRM/KMS, no audio, no suspend.**
|
||||
|
||||
---
|
||||
|
||||
## 4. Multiphase Plan
|
||||
|
||||
Phase ordering respects the canonical subsystem order (IRQ/low-level → USB → Wi-Fi →
|
||||
BT → desktop) but prioritizes host boot-blockers and the no-wired-NIC reality.
|
||||
Every phase ends with a validation gate on the **real host** (this machine is
|
||||
available — that changes everything vs. prior plans blocked on hardware access).
|
||||
Evidence language per project rules: compile-visible ≠ QEMU-bounded ≠ hardware-validated.
|
||||
|
||||
Effort scale: S (<1 week) · M (1–3 weeks) · L (3–8 weeks) · XL (8+ weeks)
|
||||
|
||||
---
|
||||
|
||||
### PHASE 0 — Host bring-up prerequisites (S, config-level, zero risk)
|
||||
|
||||
> **STATUS: COMPLETE (2026-07-20).** All items landed; affected components
|
||||
> cross-compile for `x86_64-unknown-redox`; all host-side test suites pass
|
||||
> (redox-driver-sys 72, firmware-loader 11, redbear-iwlwifi 8, redbear-wifictl 21).
|
||||
|
||||
| # | Work item | Files | Notes |
|
||||
|---|---|---|---|
|
||||
| 0.1 | **Fix e1000d wildcard collision** — add `subclass = 0x00` to e1000d match | `local/config/drivers.d/10-network.toml` + embedded copy in `config/redbear-device-services.toml` | ✅ DONE — same defect class also fixed for `rtl8168d` (Realtek ships subclass-0x80 Wi-Fi too) |
|
||||
| 0.2 | Add DMI quirk-table entry for `LG Electronics 16Z90TP` | `redbear-quirks/source/quirks.d/50-system.toml` | ✅ DONE — **and repaired the whole system-quirk pipeline**: the sibling LG entries' flags (`force_s2idle` etc.) silently parsed to empty sets (unknown names dropped). Added `SystemQuirkFlags` + `DmiSystemQuirkRule` + dual-namespace parsing in `toml_loader.rs` + `quirks::system_quirks()` consumer API in redox-driver-sys. 16Z90TP entry matches on `board_name = "16Z90TP"` (exact-match semantics; product_name carries the SKU suffix) |
|
||||
| 0.3 | Verify/port xHCI quirks for 8086:7ec0 & 8086:777d — decode Linux `0x200009810` | `redox-driver-sys/source/src/quirks/xhci_table.rs` | ✅ DONE — decoded as `SPURIOUS_SUCCESS \| LPM_SUPPORT \| INTEL_HOST \| AVOID_BEI \| DEFAULT_PM_RUNTIME_ALLOW`. Missing piece was the **universal `hci_version > 0x96 → SPURIOUS_SUCCESS`** rule (Linux `xhci.c:5477`); added it + a flag-parity test pinning the LG Gram controllers to the exact Linux flag set. The `>= 0x120 → DEFAULT_PM_RUNTIME_ALLOW` rule already existed |
|
||||
| 0.4 | Confirm graphics spawn priority: redox-drm wins over ihdgd for 0x7D51 | `drivers.d/30-graphics.toml`, `pcid.d/intel_gpu.toml`, `redbear-{mini,full}.toml` | ✅ VERIFIED CORRECT — redox-drm Intel entry priority 61 > vesad 60; redbear-mini empties `/etc/pcid.d/ihdgd.toml`; redbear-full overrides it to spawn redox-drm; `/etc/pcid.d` overrides `/usr/lib/pcid.d` via `config_for_dirs()` BTreeMap; base package stages into `/usr/lib/pcid.d` so no layer collision. No change needed |
|
||||
| 0.5 | Stage firmware blobs | `local/firmware/`, `redbear-iwlwifi/main.rs`, `redbear-wifictl/backend.rs`, `firmware-loader/blob.rs`, `redbear-device-services.toml` | ✅ DONE — staged host-verified blobs (iwlwifi bz-b0-fm-c0 **c101/c102/c103/c106** + pnvm, gf-a0 set, i915/mtl_dmc.bin + guc/huc/gsc, ibt-0093-0291.sfi/.ddc). **Key discovery:** the `c`-prefixed series is the iwlmld firmware — candidate tables rewritten to prefer c106→c101 over the legacy 92–101 series. **Fixed firmware path gap:** new linux-firmware ships iwlwifi under `intel/iwlwifi/`; added wildcard path-map to firmware-loader builtins + `/etc/firmware-fallbacks.d/10-iwlwifi.toml`. Image path confirmed: `redbear-firmware` recipe ships the full set (cache has c106) |
|
||||
|
||||
**Phase 0 discoveries beyond the original scope (all fixed, none deferred):**
|
||||
|
||||
1. `rtl8168d` had the same wildcard collision as e1000d → fixed with the same `subclass = 0` filter.
|
||||
2. The `[[dmi_system_quirk]]` TOML entries in `50-system.toml` were **dead data** — every system flag silently dropped by the parser, and no consumer API existed. Now a real pipeline: `SystemQuirkFlags` → `DmiSystemQuirkRule` → `quirks::system_quirks()` → consumers (acpid/ps2d wiring lands in Phases 4–5).
|
||||
3. `integrate-redbear.sh` AMD-only firmware staging into `firmware-loader/source/firmware/amdgpu/` never reaches the image (package ships only the binary) — the real image path is the `redbear-firmware` recipe (full linux-firmware install, local 2.8 GB cache already present). Documented here; the dead staging path is legacy cleanup, not Phase 0 scope.
|
||||
4. Firmware fallback chains in `redbear-device-services.toml` are embedded 16× (fragment composition); updates must use replace-all edits.
|
||||
|
||||
**Gate 0:** ✅ changed components cook successfully for the target;
|
||||
`redbear-iwlwifi`, `redbear-wifictl`, `firmware-loader`, `redox-driver-sys` all build + publish.
|
||||
|
||||

|
||||
|
||||
### PHASE 1 — Bare-metal boot validation (S, evidence-first)
|
||||
|
||||
This host is available — run the existing validation harnesses against it and
|
||||
record everything. **No code changes in this phase except genuine boot-blocker fixes.**
|
||||
|
||||
| # | Work item | How |
|
||||
|---|---|---|
|
||||
| 1.1 | Boot `redbear-mini` live ISO on host; capture full boot log to `local/docs/boot-logs/lg-16z90tp-*.log` | USB stick; serial capture if console fails |
|
||||
| 1.2 | Validate: 16-core SMP, NVMe root, xHCI enumeration (both controllers), PS/2 keyboard, VESA console at native panel resolution, battery/AC readout, HWP P-states, coretemp, ACPI shutdown + reboot | Manual + `redbear-info`, `redbear-ecmd` |
|
||||
| 1.3 | Validate USB-Ethernet interim networking: CDC-ECM dongle → `redbear-ecmd` → DHCP | `redbear-netctl` |
|
||||
| 1.4 | Run bounded low-level controller proofs (MSI-X, xHCI IRQ, PS/2, timer) | `local/scripts/test-lowlevel-controllers-qemu.sh` analogues on BM; record results |
|
||||
| 1.5 | Add host entry to `local/docs/HARDWARE-VALIDATION-MATRIX.md` with honest evidence levels | Per row: compile / QEMU / BM-validated |
|
||||
| 1.6 | Fix only true boot-blockers discovered (root-cause fixes per ABSOLUTE RULE) | Triage as found |
|
||||
|
||||
**Gate 1:** redbear-mini boots to login on the host with keyboard + NVMe + USB +
|
||||
shutdown/reboot verified. This is the " minimally usable " milestone.
|
||||
|
||||
---
|
||||
|
||||
### PHASE 2 — CPU & platform power validation (S–M)
|
||||
|
||||
| # | Work item | Files | Effort |
|
||||
|---|---|---|---|
|
||||
| 2.1 | Validate `cpufreqd` HWP on ARL-H: governor switching, EPP hints, per-core HWP_REQUEST | `local/recipes/system/cpufreqd/` | S |
|
||||
| 2.2 | Validate RAPL domains (pkg/pp0/pp1/dram/platform) in `redbear-power`; check 0x64D platform energy on ARL | `redbear-power/source/src/msr.rs` | S |
|
||||
| 2.3 | Validate `coretempd` + `thermald` passive cooling loop under load (stress via cub builds) | thermald + cpufreqd integration | S |
|
||||
| 2.4 | Hybrid topology: feed CPUID leaf 0x1A P/E/LP-E classification (exists in redbear-power) into cpufreqd per-cluster governor policy | `cpufreqd`, `redbear-power/cpuid.rs` | M |
|
||||
| 2.5 | Serial console bring-up via DBG2 16550 (0x3f8) for headless debugging of later phases | kernel/boot config | S |
|
||||
|
||||
**Gate 2:** `redbear-power` shows correct per-cluster frequencies, temps, RAPL power;
|
||||
thermal throttling engages and recovers under sustained load.
|
||||
|
||||
---
|
||||
|
||||
### PHASE 3 — Display: VESA → DRM/KMS on Meteor Lake (L, critical path for desktop)
|
||||
|
||||
Follows `local/docs/DRM-MODERNIZATION-EXECUTION-PLAN.md` Workstream C.
|
||||
|
||||
| # | Work item | Files | Effort |
|
||||
|---|---|---|---|
|
||||
| 3.1 | Validate vesad at native panel mode (eDP; likely 2560×1600); confirm fbcond + any framebuffer consumers | vesad/bootloader EDID handoff | S |
|
||||
| 3.2 | **Per-generation display differentiation in redox-drm**: introduce display-version-aware register layouts (Gen8 display 12 vs MTL display 14.00). Reference: `local/reference/linux-7.1/drivers/gpu/drm/i915/display/` — offsets for PIPECONF/DSPCNTR/DSPSURF/DDI_BUF_CTL on MTL | `redox-drm/source/src/drivers/intel/{mod,display}.rs` | L |
|
||||
| 3.3 | Real connector/EDID bring-up on eDP: GMBUS read at panel; bounded modeset proof via `redbear-drm-display-check` on the host | display.rs + test-drm-display-runtime.sh | M |
|
||||
| 3.4 | **DMC firmware load sequence**: CSS header parse, DMA-to-DMC-store, DC state enable — port from Linux i915 `intel_dmc.c`. Consume the already-preloaded `mtl_dmc.bin` | `intel/mod.rs`, new `intel/dmc.rs`; firmware-loader | M–L |
|
||||
| 3.5 | eDP backlight control (DDI PWM / DPCD) — brightness keys need WMI (Phase 9); scheme-level brightness first | display.rs / new backlight module | M |
|
||||
| 3.6 | GuC/HuC/GSC: manifest entries now, load sequences **deferred** (render path, not display blocker). Document as convergence work in DRM plan | `main.rs` firmware keys | S (manifest only) |
|
||||
|
||||
**Gate 3:** `redox-drm` drives the internal panel at native resolution with correct
|
||||
EDID modeset + page flips on the host; vesad remains as fallback. **This unblocks the
|
||||
whole desktop path (Qt6/KWin) on this machine.**
|
||||
|
||||

|
||||
|
||||
### PHASE 4 — Touchpad: I2C-HID chain bring-up (M)
|
||||
|
||||
| # | Work item | Files | Effort |
|
||||
|---|---|---|---|
|
||||
| 4.1 | Identify actual ACPI `_HID` of the two LPSS I2C controllers on the host (`/sys/bus/acpi/devices/*/hid` under Linux); add to `SUPPORTED_IDS` of the right driver (`intel-lpss-i2cd` or `dw-acpi-i2cd`). If the platform exposes them PCI-only, add PCI-ID (8086:7778/7779) matching as a complement to ACPI-HID matching | `local/sources/base/drivers/i2c/*` | S |
|
||||
| 4.2 | Controller bring-up: BAR/IRQ from `_CRS`, DesignWare init sequence, bus speed from ACPI; validate register-level transactions against Linux `i2c-designware` behavior | same | M |
|
||||
| 4.3 | `i2c-hidd`: probe 04CA:00CC (PNP0C50), `_DSM` HID descriptor, report descriptor fetch; IRQ line via `_CRS` (GPIO/IRQ resource → `/scheme/irq`) | `local/sources/base/drivers/input/i2c-hidd/` | M |
|
||||
| 4.4 | Multitouch digitizer report parsing (ABS_MT_* slots, tracking IDs) + forwarding through inputd → evdevd gesture module | `i2c-hidd/hid.rs`, `evdevd/gesture.rs` | M |
|
||||
| 4.5 | Host validation: pointer, click, two-finger scroll; palm-rejection tuning | — | S |
|
||||
|
||||
**Gate 4:** Touchpad fully usable on host (pointer + multitouch scroll + click).
|
||||
|
||||
---
|
||||
|
||||
### PHASE 5 — Laptop ACPI events: GPE/EC/lid/buttons (M–L)
|
||||
|
||||
This phase removes the biggest "not a real laptop" gap: event-driven power state.
|
||||
|
||||
| # | Work item | Files | Effort |
|
||||
|---|---|---|---|
|
||||
| 5.1 | **GPE dispatch infrastructure in acpid**: SCI via `/scheme/irq` (ACPI `sci_int` from FADT), GPE status/enable block access, per-GPE handler registry | `local/sources/base/drivers/acpid/src/{main,acpi}.rs` | L |
|
||||
| 5.2 | EC event loop: `SCI_EVT` poll/IRQ → `QR_EC` query → dispatch `_Qxx` AML methods; wire battery/AC change notifications (`\_SB.BAT0` notify 0x80) | `acpid/ec.rs`, new `acpid/gpe.rs` | M |
|
||||
| 5.3 | Lid switch (PNP0C0D `_LID`) + power/sleep fixed events (PM1_STS PWRBTN/SLPBTN) → scheme surfaces + kstop events | acpid + sessiond consumers | M |
|
||||
| 5.4 | Event-driven `redbear-upower` (replace polling with notify-driven refresh) | `redbear-upower` | S |
|
||||
| 5.5 | Fan: real PNP0C0B/EC fan control replacing thermald soft model | `thermald/fan.rs`, acpid EC | M |
|
||||
|
||||
**Gate 5:** Unplug/replug AC → instant battery/AC event; close/open lid → event
|
||||
logged; power button → clean shutdown flow; fan responds to thermal load.
|
||||
|
||||
---
|
||||
|
||||
### PHASE 6 — Wi-Fi BE201: the iwlmld gap (XL, hardest network work)
|
||||
|
||||
Pre-agreed reality: **this is not a device-ID add.** The Mini-MVM layer is
|
||||
iwlmvm-era; BE201 firmware is iwlmld-era with different command IDs, RX
|
||||
descriptors, and notification dispatch. Respect `WIFI-IMPLEMENTATION-PLAN.md`
|
||||
phases W0–W7.
|
||||
|
||||
| # | Work item | Files | Effort |
|
||||
|---|---|---|---|
|
||||
| 6.0 | De-risk transport on older silicon first: if any AX210-class card is available (USB/M.2 test card), validate existing Mini-MVM path end-to-end on the host's sibling hardware before touching iwlmld | redbear-iwlwifi | S (if HW available) |
|
||||
| 6.1 | Firmware plumbing: add API-102 candidates `iwlwifi-bz-b0-fm-c0-102.ucode` to tables in `main.rs` + `redbear-wifictl/backend.rs`; extend `fetch-firmware.sh`; TLV parser audit vs API 102 | `redbear-iwlwifi/source/src/{main.rs,linux_mvm.c}` | S |
|
||||
| 6.2 | **Mini-MLD layer**: port Linux 7.1 `drivers/net/wireless/intel/iwlwifi/mld/` structures — new RX/multi-link descriptor format, notification IDs, op-mode registration; gate MLD vs MVM on device family (BZ→MLD) | new `linux_mld.{c,h}` beside `linux_mvm.{c,h}`; `linux_port.c` op-mode dispatch | XL |
|
||||
| 6.3 | Bounded runtime ladder on host: probe → fw boot alive → scan (see real SSID) → association → DHCP → reconnect persistence. Use existing `redbear-phase5-wifi-*` in-guest harness | redbear-wifictl + test scripts | M (iterative) |
|
||||
| 6.4 | Integration: netctl profile, boot-time autoconnect, honest `redbear-info` states | wifictl, config fragments | S |
|
||||
|
||||
**Gate 6:** BE201 associates with the host's AP and passes traffic on the host —
|
||||
real wireless connectivity, not bounded simulation.
|
||||
|
||||
---
|
||||
|
||||
### PHASE 7 — Bluetooth: Intel CNVi BT (M)
|
||||
|
||||
| # | Work item | Files | Effort |
|
||||
|---|---|---|---|
|
||||
| 7.1 | Intel BT firmware load in `redbear-btusb`: bootloader-mode detection, `ibt-0093-0291.sfi` download, DDC apply — port from Linux `btintel.c` | `local/recipes/drivers/redbear-btusb/` | M |
|
||||
| 7.2 | HCI bring-up on the host: reset → read version → operational mode; bounded BLE battery-level slice validation via existing harness | btusb + `test-bluetooth-qemu.sh` host analogue | M |
|
||||
| 7.3 | `redbear-btctl` scan/pair/connect on host | redbear-btctl | S |
|
||||
|
||||
**Gate 7:** `redbear-btctl` sees and connects to a BLE peripheral on the host.
|
||||
|
||||
---
|
||||
|
||||
### PHASE 8 — Audio: SOF/cAVS (XL, largest single effort)
|
||||
|
||||
| # | Work item | Files | Effort |
|
||||
|---|---|---|---|
|
||||
| 8.0 | Interim (do first): USB-audio dongle path via `redbear-usbaudiod` validated on host — documented as the interim answer | redbear-usbaudiod | S |
|
||||
| 8.1 | Probe ihdad on 8086:7728 to record exact failure mode (expected: no codecs behind DSP); ensure graceful failure, never a boot hang | `ihdad/src/hda/device.rs` | S |
|
||||
| 8.2 | **SOF/AVS port**: cAVS 2.5 (ARL) DSP bring-up — power gating, ROM boot, `sof-arl.ri` firmware download via firmware-loader, IPC4 channel, HDA link DMA. Reference: `local/reference/linux-7.1/sound/soc/sof/intel/` + `sound/soc/intel/avs/`; revive `local/docs/archived/INTEL-HDA-IMPLEMENTATION-PLAN.md` HDA-011 track | new `local/recipes/drivers/redbear-sof/` (per LINUX REFERENCE SOURCE POLICY: implemented in-tree, Linux as reference only) | XL |
|
||||
| 8.3 | ALC298 codec verbs over the HDA link; speaker + headphone jack routing; DMIC later | sof codec layer | L |
|
||||
|
||||
**Gate 8:** Speaker playback on the host. (DMIC + HDMI audio are post-gate follow-ups.)
|
||||
|
||||
---
|
||||
|
||||
### PHASE 9 — Platform extras (post-core, S–M each)
|
||||
|
||||
| # | Item | Notes | Effort |
|
||||
|---|---|---|---|
|
||||
| 9.1 | **Suspend (s2idle) completion**: LPIT parser (ACPI 6.5 §5.2.9.9), MWAIT idle-loop wiring, `_PRW` wake-device enumeration, GPE wake re-arm. The host has **no S3** — this is the only suspend path | `acpid`, kernel idle | L |
|
||||
| 9.2 | LG WMI hotkeys: WMI subsystem (PNP0C14 GUID dispatch) → brightness/rfkill/volume events → evdev | new `redbear-wmi` | M |
|
||||
| 9.3 | UVC camera: new `redbear-uvcd` (UVC 1.1/1.5) — well-specified; reference Linux `drivers/media/usb/uvc/` | new recipe | L |
|
||||
| 9.4 | ISH sensor hub (8087:0AC2): only if a consumer exists (auto-rotate/ALS). Lowest priority | — | M |
|
||||
| 9.5 | Intel VT-d runtime (`intel_vtd.rs` in iommu daemon): converges acpid's orphaned DMAR parser into the daemon (per ACPI-IMPROVEMENT-PLAN ownership note). Value: DMA isolation for later Wi-Fi/GPU hardening | `local/recipes/system/iommu/` | L |
|
||||
| 9.6 | Non-critical devices documented as permanent no-driver: MEI, GNA, VPU/NPU, PMC telemetry, SMBus, SPI, UART, TPM — with one-line justification each (no consumer) | this doc | S |
|
||||
|
||||
**No stubs anywhere in this phase — per local/AGENTS.md zero-tolerance policy,
|
||||
each item is a real implementation or it does not ship.**
|
||||
|
||||
---
|
||||
|
||||
### PHASE 10 — Validation, quirks, and hardening (continuous)
|
||||
|
||||
| # | Item |
|
||||
|---|---|
|
||||
| 10.1 | Keep `HARDWARE-VALIDATION-MATRIX.md` row for 16Z90TP current after every phase gate |
|
||||
| 10.2 | Every discovered hardware workaround → data-driven quirk entry (compiled table or `redbear-quirks` TOML + DMI match), never an `#ifdef`-style special case |
|
||||
| 10.3 | Boot logs per milestone archived to `local/docs/boot-logs/` |
|
||||
| 10.4 | Durability: all source changes land as fork commits (`local/sources/*`) or patches (`local/patches/*`) in the same session — per DURABILITY POLICY |
|
||||
| 10.5 | Upstream-sync safety: any new generic infrastructure (GPE dispatch, Mini-MLD, SOF) is implemented in the canonical component (acpid / redbear-iwlwifi / new recipe), not as host-specific hacks |
|

## 6. Suggested Execution Order (effort-sequenced)
|
||||
|
||||
1. **Phase 0 + 1** — boot the host, fix the e1000d collision, capture the matrix (week 1)
|
||||
2. **Phase 4 (touchpad)** + **Phase 2 (power)** — makes it a *usable* laptop (weeks 1–3)
|
||||
3. **Phase 5 (ACPI events)** — makes it a *real* laptop (weeks 3–6)
|
||||
4. **Phase 3 (display DRM)** — desktop path on the host (weeks 3–10, parallel)
|
||||
5. **Phase 6 (Wi-Fi iwlmld)** — the XL rock to push (start early, longest lead time)
|
||||
6. **Phase 7 (BT)**, **Phase 8 (audio)** — after their USB/PCI substrates are proven
|
||||
7. **Phase 9 extras** — as capacity allows
|
||||
|
||||
## 7. Explicitly Out of Scope (per policies)
|
||||
|
||||
- No removal/ignore/comment-out of any package or device entry that fails to probe
|
||||
(ABSOLUTE RULE) — failures get root-cause fixes or honest "unsupported" reporting.
|
||||
- No new branches, repos, or submodules without the documented necessity case.
|
||||
- Linux kernel source is reference-only; all ports are in-tree implementations.
|
||||
- TPM2/secure-boot/ME features — no consumer, no plan.

|
||||
`match.*` keys plus optional `pci_vendor` / `pci_device` selectors. Runtime use

A single `flags = [...]` array in a `[[dmi_system_quirk]]` entry may mix

against both mappings (`PCI_FLAG_NAMES` and `SYSTEM_FLAG_NAMES`) and warns

### System Quirks (SystemQuirkFlags)
|
||||
|
||||
Machine-wide flags matched by DMI data rather than PCI ID. Mirrors Linux's
|
||||
DMI-matched platform quirks (`drivers/acpi/resource.c`
|
||||
`irq1_level_low_skip_override[]`, `drivers/input/keyboard/atkbd.c` fixups,
|
||||
`drivers/acpi/sleep.c` s2idle preferences). Consumers are the daemons that own
|
||||
the subsystem.
|
||||
|
||||
| Flag | Consumer | Meaning |
|
||||
|------|----------|---------|
|
||||
| `FORCE_S2IDLE` | acpid | Firmware lacks/breaks `\_S3`; use s2idle (Modern Standby) for all sleep |
|
||||
| `ACPI_IRQ1_SKIP_OVERRIDE` | acpid | Keep the DSDT's ActiveLow trigger for IRQ1 (i8042 keyboard) |
|
||||
| `KBD_DEACTIVATE_FIXUP` | ps2d | Skip the AT keyboard deactivate command on cleanup/reconnect |
|
||||
| `NO_LEGACY_PM1B` | acpid | Single PM1 control block (no PM1b); belt-and-braces alongside the FADT check |
|
||||
|
||||
TOML names: `force_s2idle`, `acpi_irq1_skip_override`, `kbd_deactivate_fixup`,
|
||||
`no_legacy_pm1b`.
|
||||
|
||||
### Firmware path-map fallbacks
|
||||
|
||||
`firmware-loader`'s builtin fallback table maps the historical flat
|
||||
`/lib/firmware/iwlwifi-*` request paths into the post-2026 linux-firmware
|
||||
layout (`intel/iwlwifi/iwlwifi-*`):
|
||||
|
||||
- `iwlwifi-*.ucode` → `intel/iwlwifi/iwlwifi-*.ucode`
|
||||
- `iwlwifi-*.pnvm` → `intel/iwlwifi/iwlwifi-*.pnvm`
|
||||
|
||||
The same entries exist in `/etc/firmware-fallbacks.d/10-iwlwifi.toml`
|
||||
(embedded in `config/redbear-device-services.toml`).
