QUIRKS-SYSTEM: mark Blocker 2 + Blocker 4 RESOLVED; refresh P0 wiring checklist

Browse Source 
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.

`product_name`, `product_version`, `bios_version`, plus the new
`bios_vendor` and `bios_date` fields (see Blocker 5).
**Status:** ✅ RESOLVED 2026-06-07 — Three-part chain lands across
bootloader, kernel, and acpid:
1. **bootloader** (commit `259a621`, `local/sources/bootloader/src/os/uefi/smbios.rs`):
new `find_smbios()` helper searches UEFI Configuration Tables for
`SMBIOS3_TABLE_GUID` (0xF2FD1544-9794-4A2C-992E-E5BBCF20E394), parses
the entry point with `dmidecode::EntryPoint::search`, then copies the
EPS and the SMBIOS table into page-aligned buffers. Four new u64
fields on `KernelArgs` (`smbios_eps_base/size`, `smbios_table_base/size`)
carry the addresses to the kernel.
2. **kernel** (commit `a4ba465`, `local/sources/kernel/src/scheme/smbios.rs`):
new `SmbiosScheme` exposes `/scheme/kernel.smbios/eps` and
`/scheme/kernel.smbios/table` to userspace. Mirrors `DtbScheme`.
The raw table is sufficient — the SMBIOS 2.x and 3.x structure
formats are identical, so the EPS version is irrelevant to the
parser in acpid. The scheme is silently inactive when SMBIOS3 is
not present (BIOS or non-UEFI paths).
3. **acpid** (commit `fa91cee4`, `local/sources/base/drivers/acpid/src/dmi.rs`):
new `dmi.rs` module walks the SMBIOS structure table, splits each
structure into formatted area + string area (1-based string indices,
null-terminated, double-null terminator), and extracts 9 DMI fields
(the same set Blocker 5 added to the consumer-side `DmiInfo`):
`sys_vendor`, `board_vendor`, `board_name`, `board_version`,
`product_name`, `product_version`, `bios_version`, `bios_vendor`,
`bios_date`. Two scheme endpoints:
- `/scheme/acpi/dmi` (single file, key=value text, the format
`parse_dmi_data()` in redox-driver-sys expects)
- `/scheme/acpi/dmi/{field}` (per-field files, the format i2c-hidd
opens individually)
Eight new dmi.rs unit tests cover Type 0/1/2 parsing, the key=value
text round-trip, the malformed-table graceful paths, and the
string-index-0-means-absent semantic. All 120 redox-driver-sys tests
continue to pass.
**Net effect:** Every compiled-in DMI rule in `dmi.rs:373` and every
`[[dmi_system_quirk]]` / `[[dmi_xhci_system_quirk]]` TOML entry now
fires against real firmware data, not synthetic fixtures. The
`read_dmi_info()` warn-once (Gap 17, commit `abce96f1e`) becomes a
no-op on real hardware.

**Status:** ✅ RESOLVED 2026-06-07 — `local/sources/base/drivers/usb/xhcid/src/main.rs:152`
now calls `lookup_xhci_controller_quirks_full(vendor, device, dmi_info.as_ref())`
instead of `lookup_xhci_controller_quirks`. The DMI information is read once
at driver startup via
`redox_driver_sys::quirks::dmi::read_dmi_info().ok()`. When `/scheme/acpi/dmi`
is absent (e.g., boot stage before acpid is up, or acpid did not produce
DMI for this firmware), the call falls through gracefully and only the
non-DMI rules fire. The DMI path now has a real producer (Blocker 2
commit `fa91cee4` in this turn), so on real hardware the DMI rules in
`[[dmi_xhci_system_quirk]]` TOML entries and the future compiled-in
DMI xHCI table will now reach the lookup function. The full variant
returns `PciQuirkLookup` with both flags and `actions: Vec<QuirkAction>`,
so QuirkAction execution becomes available for xHCI the moment a
`PciConfigWriter` is wired (Blocker 1). The R6 enforcement bits
(`ZERO_64B_REGS`, `NO_ASPM`, `NEED_IOMMU`, `NO_MSIX`, `NO_MSI`) continue
to be applied at the same sites in `xhci/mod.rs`. The pre-existing
`log_unenforced_xhci_quirks()` helper at `xhci/mod.rs:526` remains
in place for surfacing R8 dormant bits; calling it is queued as part
of Blocker 3 (usbhidd rewiring) since both share the same wakeup path.

**Status:** R11 is now data-only. The acpid producer, the DMI struct,

the Linux ACPI rules and writing them into
`quirks.d/45-acpi-osi.toml` through `48-acpi-battery.toml`. The
`acpid` driver must own `_OSI` override dispatch; the new `ec`
subsystem in acpid needs the timing override consumer; the
battery/sleep/button rules need the appropriate consumer
daemons (`redbear-upower`, etc.) which are partially stubbed.
