From ab9f520f85fe7eae0e370dbf99054fbc25e26dee Mon Sep 17 00:00:00 2001 From: Red Bear OS Builder Date: Sun, 7 Jun 2026 15:47:36 +0300 Subject: [PATCH] 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. --- local/docs/QUIRKS-SYSTEM.md | 175 +++++++++++++++++++++++++++++------- 1 file changed, 143 insertions(+), 32 deletions(-) diff --git a/local/docs/QUIRKS-SYSTEM.md b/local/docs/QUIRKS-SYSTEM.md index e298bfc63f..0133f2151c 100644 --- a/local/docs/QUIRKS-SYSTEM.md +++ b/local/docs/QUIRKS-SYSTEM.md @@ -1,5 +1,25 @@ # Red Bear OS Hardware Quirks System +## Recent Activity (2026-06) + +| Date | Commit | What | +|---|---|---| +| 2026-04 | R0-R10 (R0-R5 `86902d481`, R6 `5e44191c9` + xhcid `3b0d02d8`, R7-R9 `b56b810c0`, R10 `b324cf67e`+`6f1df4f04`) | All pushed to gitea `0.2.3` | +| 2026-06 | R1-R10 audit (`60b200601`) | 5 critical blockers + 15 medium/low gaps identified, comprehensive R11-R22 plan added | +| 2026-06 | Blocker 5 (`9a28b68ef`) | DMI struct extension: `bios_vendor`, `bios_date` added to `DmiInfo` + `DmiMatchRule` | +| 2026-06 | Gap 17 (`abce96f1e`) | `read_dmi_info()` logs `warn!` on first failure (rate-limited) | +| 2026-06 | Blocker 4 (`be95fea0`, base fork) | xhcid calls `lookup_xhci_controller_quirks_full` with DMI | +| 2026-06 | Blocker 2 (bootloader `259a621`, kernel `a4ba465`, acpid `fa91cee4`) | End-to-end SMBIOS → `/scheme/acpi/dmi` chain.
