Add dp_aux.rs implementing DisplayPort AUX channel for EDID reads
and DPCD capability queries. Critical for Xe2/Arrow Lake which lacks
GMBUS and must use DP AUX for all EDID operations.
- dp_aux.rs: DpAux struct with per-port AUX channel (CTL at 0x64010,
DATA at 0x64014, 0x100 stride). Implements do_transfer() with
native read/write and I2C-over-AUX protocols, wait_for_completion()
with busy/done/timeout/receive_error detection, read_dpcd() for
DPCD register access, read_dpcd_caps() for capability enumeration,
and read_edid() via I2C-over-AUX (MOT-based segmented reads)
- mod.rs: declare dp_aux module, add DpAux import, add dp_aux: Vec<DpAux>
field to IntelDriver, initialize one DpAux per port in constructor
Linux reference: intel_dp_aux.c, intel_dp_aux_regs.h

Kernel, relibc, and base forks now use the full pre-patched source
from the frozen 0.1.0 release archives (including .git history).
Build verification:
- kernel: BUILDS from local/sources/kernel
- relibc: BUILDS from local/sources/relibc
- base: BUILDS from local/sources/base
- redoxfs: BUILDS from local/sources/redoxfs
The mini ISO build fails due to pre-existing cached pkgar signature
issues (not migration-related).
- Create source symlinks for all 7 core components (kernel, relibc, base,
bootloader, installer, redoxfs, userutils) pointing at local/sources/
- Create redoxfs and userutils fork repos from frozen 0.1.0 archives
- Fix relibc-tests recipes: replace patch commands with direct fork build
- Archive all 417 patch files to local/archived/patches-2026-06-migration/
- Full AGENTS.md rewrite: remove all 31 remaining stale patch references,
update DURABILITY POLICY to describe git commit workflow, update WHERE TO
LOOK table, fix build flow description, replace Recipe Patch Wiring section
with Recipe Source Configuration
- Zero active patches = [...] arrays remain in any recipe.toml file
- All 13 remaining grep hits for 'patches' are TODO comments in WIP recipes
Comprehensive 6-phase plan (1,055 lines) for updating the Intel GPU driver from current 1,590-line stub to full Gen9+ support ported from Linux 7.1 i915. Covers register abstraction, GMBUS I2C, DMC firmware, power wells, CDCLK, display pipeline, modesetting, and hardware validation.

userutils compiled redox-rt with default-features=false, disabling the proc feature. This caused login's fork to not pass proc fd to child shell, triggering assertion failed: info.has_proc_fd in redox-rt. P8 patch enables features=['proc']. Verified: zero panics on boot, login works for user/root.

The driver incorrectly labeled Lunar Lake IDs (0x6420/64A0/64B0) as
Arrow Lake, and placed the real Arrow Lake IDs (0x7D41/7D51/etc.) in the
Meteor Lake bucket. This meant:
- Arrow Lake notebooks were misidentified as Meteor Lake
- Lunar Lake was completely missing from the device tables
- The 0xB640 ID (ARL-H) was also misfiled
Fix:
- Move real Arrow Lake IDs (0x7D41, 0x7D51, 0x7DD1, 0x7D67, 0xB640)
to INTEL_GEN12_ARL_IDS
- Move Lunar Lake IDs (0x6420, 0x64A0, 0x64B0) to INTEL_GEN12_LNL_IDS
- Map Arrow Lake DMC firmware to INTEL_MTL_DMC_KEYS (mtl_dmc.bin),
since Arrow Lake uses the same display IP 14.0 as Meteor Lake
- Remove Arrow Lake IDs from the Meteor Lake bucket
Per Linux 7.1 reference: Arrow Lake display engine is IP 14.0 (Xe_LPD+),
same as Meteor Lake — NOT Xe2. The i915-style register programming is
correct for Arrow Lake.
- ps2d: PS/2 keyboard/mouse (init service + driver-manager wildcard match)
- i2c-hidd: I2C HID keyboard/touchpad (init service + driver-manager match)
- intel-thc-hidd: Intel Touch Host Controller HID (init service + PCI match)
Fixes i2c-hidd path: /usr/bin/i2c-hidd (not /usr/lib/drivers/).
These drivers were already built in the base package but were not wired
into the boot process. Modern Intel notebooks typically use either
i8042 EC emulation (PS/2) or I2C HID for keyboard/touchpad.
The capability bitmask patch was missing the critical proc.rs hunk that
derives caps from euid when procmgr writes ProcSchemeAttrs to a child
context. Without this, all child processes had caps=0, causing
EACCES on dup("create-scheme") and crashing boot.
Fix: in ContextHandle::Attr kwrite path, after setting euid/egid/pid/prio,
set guard.caps = CAP_ALL when euid==0, else 0.
P27-capability-bitmask.patch was generated against an incorrectly
patched source tree, causing hunk mismatches in validate-patches.
Regenerated from clean upstream + P0-P26 baseline using git diff -U0 -w.
All 39 patches now validate successfully.
Replace all 9 kernel uid==0 privilege checks with a capability bitmask
model. Adds caps:u64 field to Context and CallerCtx, with CAP_ALL for
root processes. Zero behavioral change - uid==0 still gets all caps.
New module: src/scheme/caps.rs with 10 capability constants.
9 check sites converted: acpi, irq, memory, debug, serio, sys (msr+write),
scheme registration, and fchown.
Patch: local/patches/kernel/P27-capability-bitmask.patch
- login.rs: drop privileges via setresugid after authentication
- login.rs: add namespace isolation to password auth path (was missing)
- login.rs: add drm, input schemes to DEFAULT_SCHEMES
- sudo service: rename 00_sudo -> 12_sudo, type daemon (no boot block)
- Branded login screen with figlet RedBear OS v0.2.2 'Liliya'
- Root user kept but not advertised on login screen
- P6-login-privilege-drop.patch generated and wired
Implements Phase 1 of Plan 9 namespace privilege model:
login creates restricted namespace (mkns/setns) then drops
uid/gid to authenticated user before spawning shell.
Three fixes for the KWin DRM device discovery failure:
1. drm_scheme_ready(): replace head -c 1 with exec 3< open test.
Reading from a DRM scheme fd blocks because the scheme expects
ioctl-style request/response, not streaming reads. Use open()
success as the scheme availability probe instead.
2. ConsoleKitSession::create(): return nullptr immediately.
The D-Bus isServiceRegistered() call can block indefinitely when
the bus daemon doesn't fully implement org.freedesktop.DBus.
With both LogindSession and ConsoleKitSession returning nullptr,
Session::create() falls through to NoopSession which uses plain
open() for DRM device access.
3. Boot chain deps: redox-drm depends on driver-manager,
greeter depends on evdevd (keyboard/mouse ready before login).
Also includes: KF6 CMake build fixes, Qt6 platform patches,
libdrm Redox ioctl shim, and wayland.toml scheme check fix.
The cookbook resolves patch paths from recipe.dir which is the symlink
path (recipes/libs/libdrm/), not the physical path (local/recipes/).
Fix ../../../patches/libdrm/ → ../../../local/patches/libdrm/ to
match the convention used by kernel, base, relibc, and other recipes.
Replace 95-line manual symlink list with auto-discovery of all
local/recipes/<category>/<name>/ directories. This fixes 15 missing
symlinks that would have blocked the redbear-full build, including
critical packages: libdrm, qtbase, qtwayland, libinput, libevdev,
seatd, and wayland-protocols.
Special-case aliases preserved:
- kf6-kirigami → kirigami (KDE expects both names)
- wip/wayland/qt6-wayland-smoke (historical WIP path)
L1: Add make qemu-ram target — copies disk image to host tmpfs before
QEMU boots, eliminating host disk I/O during OS runtime.
Usage: make qemu-ram CONFIG_NAME=redbear-full QEMU_MEM=12288
L2: Create local/recipes/AGENTS.md — comprehensive catalog of all 165
custom recipes across 15 categories with descriptions.
L3: CollisionTracker already fully implemented and wired into installer
(recipes/core/installer/source/src/collision.rs, 267 lines).
L4: Add scripts/validate-collision-log.sh to make validate target —
scans build logs for [COLLISION-ERROR]/[COLLISION-WARN] markers
from the runtime CollisionTracker.
Add #ifdef __redox__ path to drmGetDeviceFromDevId() that mirrors the
working drmGetDevice2() Redox implementation. On Redox there is no
/dev/dri/ directory — DRM devices are accessed via /scheme/drm/card0.
The patch constructs a drmDevice with both PRIMARY and RENDER nodes
pointing to /scheme/drm/card0, since the redox-drm scheme serves both
roles through a single endpoint.
Also fixes drmParseSubsystemType() to return DRM_BUS_PCI on Redox.
Fix P3 patch paths (strip local/recipes/libs/libdrm/source/ prefix
from diff headers so patches apply correctly during repo fetch).
logd was starting before randd, causing a panic when the Rust std
library tried to get random data from /scheme/rand which didn't
exist yet. This cascaded into fbbootlogd failing (no log scheme)
and vesad timing out, blocking the console/getty chain entirely.
P58 adds:
- 00_logd.service: requires = ["00_randd.service"]
- 20_fbbootlogd.service: requires = ["00_logd.service"]
Result: mini ISO boots to RedBear Login: prompt with working
console, D-Bus, driver-manager, and all boot stage markers.
When LOGD_JSON=1 is set in the environment, logd formats all log
lines as JSON objects with timestamp, source, and message fields.
Also fixes indentation issues in P51 logd rotation patch.
The service_logs declaration hunk was targeting line 48 instead of 49,
causing patch to insert it inside the let persistent_log chain instead
of inside the thread spawn closure.
P53: Change itr_tracker insertion point from line 46 to 47
so it applies after NetworkScheme::new() closing, not inside it.
P45: Add log.workspace = true to ixgbed Cargo.toml since
P45 adds log::error! usage to ixgbed main.rs.
P46 migrated ac97d to pci_allocate_interrupt_vector but missed
adding to the pcid_handle parameter. This caused build
failure: cannot borrow pcid_handle as mutable.
The original P49 patch had incorrect line numbers that caused
patch --fuzz=3 to insert cpu_id field and methods at wrong locations,
corrupting irq_helpers.rs. Regenerate from clean P0-P48 baseline.
