e1000d was the last NIC driver using legacy IRQ (irq.irq_handle()).
Migrated to pci_allocate_interrupt_vector which tries MSI-X first,
then MSI, then falls back to legacy INTx — matching rtl8168d, rtl8139d,
ihdad, ihdgd, and nvmed.
63-line patch at local/patches/base/P6-e1000d-msi-migration.patch,
symlinked and wired into recipes/core/base/recipe.toml.
- udev-shim: replace .expect() with graceful errors (no more panic on Broken pipe)
- P4-initfs: remove duplicate sessiond (conflicted with config)
- accessibility/ime/keymapd: break instead of exit(1) on EBADF
- P6 driver patches rebased
- Docs: archive old reports, add implementation master plan
Base: fix P6-driver-new-modules.patch (ed format -> unified diff) for new
driver modules (ncq, itr, phy). P6-driver-main-fixes.patch now applies with
offset on current upstream source.
Relibc: remove stale P5-named-semaphores (upstream has stubs), add
P10-stack-size-8mb and P11-getrlimit-getrusage (per-process rlimit table,
sysconf integration, getdtablesize fix, null-pointer safety).
Kernel: consolidate 29 individual patches into single redbear-consolidated.patch.
Userutils: P5-redbear-branding replaces P4-login-rate-limit.
Recipe.toml changes now committed so they survive source resets.
MouseTx::handle() treated 0xFE (PS/2 RESEND) as an unknown response,
causing mouse init to fail on hardware where the mouse requests a
resend during the reset/command exchange. Now resends the current
command byte when the mouse returns 0xFE, matching the PS/2 protocol.
Add redbear-usb-storage-check in-guest binary that validates USB mass
storage read and write I/O: discovers /scheme/disk/ devices, writes a
test pattern to sector 2048, reads it back, verifies match, restores
original content. Updates test-usb-storage-qemu.sh with write-proof
verification step.
Includes all accumulated Red Bear OS work: kernel patches, relibc
patches, driver infrastructure, DRM/GPU, KDE recipes, firmware,
validation tooling, build system hardening, and documentation.
The init system parser (serde deny_unknown_fields) rejects [service]
sections in .target files. The P4-initfs-dbus-services patch was
creating 05_boot_essential.target and 12_boot_late.target with a
no-op [service] section (cmd=/usr/bin/true). Removed those sections
so targets only contain [unit].
This eliminates "unknown field service, expected unit" init warnings
that could prevent proper service dependency resolution.
P3-3: fbcond scrollback is now fully functional:
- text.rs: 1000-line ring buffer captures all console output
- scheme.rs: new Scrollback handle type, path/N/scrollback open
- main.rs: Scrollback match arm in event loop
- Users can read scrollback via:
cat /scheme/fbcon/2/scrollback
19/19 patches. base + base-initfs build.
Fixed common dependency path (../../common → ../common).
Added workspace member entry for drivers/thermald.
thermald now builds as part of base recipe.
19/19 patches. base + base-initfs build.
P3-3: fbcond scrollback — captures last 1000 lines of text output
in ring buffer, exposes via read_scrollback(). Patch created but
needs line number adjustment for clean application.
P3-5: thermal daemon source created at drivers/thermald/. Reads
ACPI thermal zone temperature, logs warnings >65°C, errors >80°C.
Needs Cargo.toml workspace integration and recipe.toml BINS entry.
Part of COMPREHENSIVE-FIX-PLAN-FINAL P3 implementation.
D-Bus daemon, sessiond, and seatd all running on redbear-full.
User lookup warnings are pre-existing Redox D-Bus config issue
(does not affect functionality).
getty converts numeric args to /scheme/fbcon/{N} paths.
Non-numeric args (like ttyS0) are treated as literal paths
which don't exist in Redox. Changed to:
- 29_activate_console: inputd -A 2
- 30_console: getty 2 → /scheme/fbcon/2 (VT2 login)
- 31_debug_console: getty 3 → /scheme/fbcon/3 (VT3 debug)
Serial console (ttyS0) has no standard scheme path in Redox.
Login prompt is on the framebuffer console (requires graphical QEMU
or VNC to view).
Boot process now includes:
- 25_serial_getty.service: getty on serial console (visible in QEMU -nographic)
- 29_activate_console.service: inputd -A 2 (activate VT2)
- 30_console.service: getty on VT2 (framebuffer console)
Fixed hunk counts (7→8, 8→9) for correct patch application.
Services use 'oneshot_async' type for fire-and-forget startup.
ZSH is the default shell for all user accounts (base.toml, mini, full, greeter).
At initfs time, /var/log/ doesn't exist (rootfs not yet mounted).
Changed persistent_log from File to Option<File> with .ok() instead
of .unwrap_or_else(|| panic!()). If the file can't be opened, logging
continues without persistence — no crash.
QEMU verification: system boots through initfs→rootfs→switch_root→userland.
Colored init output visible. 25+ services start successfully.
P2-2: Login rate limiting (userutils/login.rs):
- Tracks consecutive failures, resets on success
- 3+ failures: exponential delay up to 30 seconds
- Applies to both password and blank-password login paths
P2-3: Network stack in initfs (base-initfs + service files):
- Added e1000d, rtl8168d to base-initfs BINS
- 60_smolnetd.service: network stack in initfs
- 61_dhcpd.service: DHCP client in initfs
- Network available before switch_root
Part of COMPREHENSIVE-FIX-AND-IMPROVEMENT-PLAN Phases P2.
Phase B1+B2 from BOOT-PROCESS-AUDIT:
- 45_usbscsid.service: USB mass storage driver in initfs (requires xhcid)
- 30_redox-drm.service: DRM/KMS display driver in initfs (requires hwd+pcid-spawner)
Both condition-architecture-gated to x86/x86_64.
Phase A1 from BOOT-PROCESS-AUDIT. The ACPI shutdown path now:
- Validates PM1a port is non-zero before writing
- Waits 3 seconds for power-off, then retries with PM1b+SLEEP_EN
- Falls back to keyboard controller reset (0x64=0xFE) on failure
- Handles SLP_TYPb correctly
- Removes fragile Pio::new()+write() without validation
logd now writes all log output to /var/log/system.log (5MB auto-rotation)
in addition to existing scheme listeners. Falls back to /tmp/logd-fallback.log
if /var/log is unavailable. Logs survive reboots for post-mortem analysis.
Part of Phase A2 (Boot Reliability) from BOOT-PROCESS-AUDIT-2026-05-03.
The 556MB monolithic redox.patch was impossible to manage, unreviewable,
blocked GitHub pushes, and could only grow. This commit:
- Moves all 64 absorbed patches from absorbed/ to active use in base/
- Removes the absorbed/ directory (consolidation history is now PATCH-HISTORY.md)
- Removes the redox.patch symlink from recipes/core/base/
- Fixes all recipe symlinks to point to active patches (not absorbed/)
- Patches are now individually wired, reviewable, and independently rebasable
The redox.patch mega-file is no longer needed — individual patches
are applied directly from the recipe.toml patches list.
redox.patch is 556MB, exceeding GitHub's 100MB file size limit.
Split into 7 chunks of ~90MB each under local/patches/base/redox-patch-chunks/.
Reassembly script: local/patches/base/reassemble-redox-patch.sh.
Added redox.patch to .gitignore to prevent future push failures.
Build system (src/cook/fetch.rs):
- Atomic patch application: applies patches to staging directory (cp -al),
atomically swaps on success, discards on failure — source tree is never
left in a partially-patched state
- normalize_patch(): strips diff --git/index/new-file-mode headers that the
build system's patch command does not recognize
- cleanup_workspace_pollution(): removes orphaned recipes/Cargo.toml and
recipes/Cargo.lock to prevent workspace conflicts
- Added --allow-protected CLI flag to repo binary
Input stack (local/patches/base/P3-*.patch):
- P3-ps2d-led-feedback: PS/2 LED state handling + InputProducer migration
- P3-inputd-keymap-bridge: InputProducer enum, keymap bridge query
- P3-usbhidd-hardening: HID descriptor validation, static lookup table,
8-button mouse support, transfer retry with exponential backoff
- P3-init-colored-output: ANSI-color coded init daemon output (green OK,
red FAILED, yellow SKIP/WARN)
XKB bridge (local/recipes/system/redbear-keymapd/source/src/xkb.rs):
- Parses X11 xkb/symbols/* format, maps XKB keycodes to PS/2 scancodes,
80+ X11 keysym names to Unicode, 4-level key support
Patch governance (local/patches/base/absorbed/README.md):
- Documents consolidation of P0-P3 patches into redox.patch
Verified in QEMU: compositor runs, no exceptions, DRM active.
Greeter reaches 'compositor ready, launching greeter UI'.
All canaries present. Boot completes to login prompt.
The 17,046-line redox.patch monolith is no longer referenced in the base
recipe. All 27 individual P2 patches are now listed explicitly in
recipe.toml with symlinks to local/patches/base/.
Coverage gap closed: ixgbed/src/device.rs was the only file not covered
by any individual patch. Added P2-ixgbed-error-handling.patch for the
10GbE Intel driver error handling (println → log::info/warn/error).
Build verified: CI=1 make r.base completes successfully with the new
patch list. The monolith file is preserved as backup but no longer applied.
The previous fire-and-forget fix passed hwd's own INIT_NOTIFY fd to pcid,
but that fd had CLOEXEC set (by daemon::Daemon::new), so pcid inherited
a closed fd and panicked in PipeWriter::from_raw_fd.
Fix: create a new pipe in hwd before spawning pcid. Pass the write end
as INIT_NOTIFY with CLOEXEC cleared (via pre_exec). Drop the read end
immediately — pcid's daemon.ready() will get EPIPE, which is silently
ignored by the daemon library. This gives pcid a valid fd while still
being fully non-blocking from hwd's perspective.
Root cause: hwd used daemon::Daemon::spawn(pcid) which blocks waiting
for pcid's readiness signal. But pcid only signals readiness after
completing full PCI enumeration. On real Intel hardware with complex
ACPI tables, enumeration can hang (unresponsive device, AML deadlock),
causing pcid to never signal readiness, hwd to never signal its own
readiness, and init to stall the entire initfs phase.
Fix: replace blocking daemon::Daemon::spawn with std::process::Command::spawn
(fire-and-forget). hwd signals its own readiness immediately, allowing
init to continue the initfs phase regardless of pcid's enumeration progress.
pcid runs independently and registers the pci scheme when ready.
Also: promote pcid enumeration completion log from debug to info level.
Suppress EPIPE in SchemeDaemon::ready_with_fd() to eliminate broken pipe
errors from gpiod, i2cd, ucsid at boot. Handle ENODEV gracefully in audiod
when /scheme/audiohw is absent. Both fixes verified: QEMU boots to login
prompt with zero non-fatal errors, patch applies cleanly on clean rebuild.
- IOAPIC: enable full IOAPIC initialization on AMD/Intel bare metal,
dual GSI 0/2 timer mapping for platform compatibility, NMI handler
uses raw COM1 PIO writes to avoid mutex deadlock
- HPET: counter validation, graceful fallback to PIT when HPET missing
- PS/2: fix 0xFE RESEND handling in all MouseState variants, add
controller flush/self-test retry/aux port test from Linux 7.0
- ACPI: defer AML evaluation to avoid blocking initfs driver spawn
- VT chain: remove duplicate rootfs service files (inputd, vesad,
fbcond, getty) that were already handled by initfs phase 1 and the
legacy 30_console script from minimal.toml
- QEMU verified: boots to login prompt, 20 rootfs units (was 26),
single login prompt (was double), only 1 expected error (wifictl)
215 fixes across 33 Rust source files replacing unwrap/expect/panic
with graceful error handling in init, all boot-critical daemons,
and the six graphics driver packages. Fixes inverted scheduler
conditions_met() logic that prevented rootfs from mounting.
Both P2 patches were stale — generated against an older upstream HEAD whose
context lines shifted after redox.patch modified the same files. Regenerated
from scratch against the current upstream commit so they apply cleanly.
