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.
Analysis shows existing P0/P1 patches cover ~85% of kernel/redox.patch
(2,335 lines). Extract the two uncovered sections as new patches:
P2-redbear-os-branding.patch (65 lines): Redox->RedBear OS branding in
aarch64, riscv64, x86_shared start files + device init logging milestones.
P3-eventfd-kernel.patch (368 lines): Full EventCounter implementation
in event.rs with blocking read/write, semaphore mode, wait conditions,
and EventScheme eventfd path dispatch in scheme/event.rs.
Update desktop status doc with Wave 2 changes.
unassign_device: clear DTE and submit hardware INVALIDATE_DEVTAB_ENTRY
and INVALIDATE_INTERRUPT_TABLE commands with completion wait (was
previously only clearing the software HashMap).
TRANSLATE opcode (0x0012): walk IOMMU page tables for IOVA-to-physical
address resolution.
fstat: return proper MODE_DIR/MODE_FILE and sizes for all handle kinds
(Root, Control, Domain, Device).
Remove #TODO from recipe.toml.
Enforce that every source-tree edit must be mirrored to local/patches/
and wired into recipe.toml in the same session. Apply the policy
retroactively to userutils res/issue and res/motd (Redox → Red Bear).
relibc select_epoll() forced timeout=0 when any FD doesn't support epoll
(e.g. TTY on Redox), causing busy-loop. Poll with 100ms interval instead.
Also add stdint.h to signal/cbindgen.toml sys_includes so signalfd_siginfo
struct types (uint32_t, int32_t) resolve without build errors.
Phase 4 KDE Plasma preparation:
kded6: new recipe at local/recipes/kde/kf6-kded6/ building the KDE
daemon from source. Depends on kf6-kconfig, kf6-kcoreaddons,
kf6-kcrash, kf6-kdbusaddons, kf6-kservice — all already built.
Added to redbear-full.toml package list. D-Bus activation file
already existed; removed TODO now that recipe exists.
kirigami: rewrite from stub to real CMake build. qtdeclarative
(Qt6Quick) is now available, so the real Kirigami can be built
instead of installing dummy cmake configs and a static lib placeholder.
Added qtshadertools and qtsvg as additional dependencies.
Phase 3 input chain wiring:
udev-shim: when scheme:evdev is registered (by evdevd), probe for
event0..event7 devices and create /dev/input/eventN nodes pointing to
scheme:evdev/eventN. This bridges evdevd's evdev devices into the
/dev/input namespace that libinput and compositors expect.
libinput: remove -Dudev=false and add libudev-stub as a dependency.
The libudev-stub recipe provides libudev.so that reads from scheme:udev
(udev-shim), giving libinput a working udev enumeration path instead of
stub functions that return NULL.
Input chain is now: hardware → /scheme/input → evdevd → scheme:evdev →
udev-shim → /dev/input/eventN → libudev-stub → libinput → KWin.
Upstream relibc netdb DNS lookup has two bugs exposed by Rust 2024 edition
strict unsafe handling:
1. packet_data is moved into Box::via into_boxed_slice() but the retry
loop tries to call packet_data.as_ptr() on the moved value. Use the
already-created raw pointer packet_data_ptr instead.
2. close() is a safe function in relibc, so wrapping it in unsafe{}
triggers unused-unsafe (promoted to error by -D unused-unsafe). Remove
the unnecessary unsafe blocks around close() calls.
Patch carries in local/patches/relibc/P3-netdb-lookup-retry-fix.patch and
is applied via the relibc recipe patches list.
The #[cfg(target_os = "redox")] variant of wait_for_shutdown had dead code
after the tokio::select! block. The select already returns Result<(), _>, so
the trailing Ok(()) was unreachable and caused a type mismatch when the compiler
tried to coerce the select result into (). Remove the dead code.
Consolidate compile target naming (redbear-live, redbear-grub-live-full,
etc.), add config/redbear-grub-live-full.toml, make redbear-live-full-grub
a legacy alias, update build-iso.sh to support all GRUB live targets, and
sync AGENTS.md/README.md build command documentation.
Add ATT/GATT protocol types to btusb hci.rs: AttPdu with 8 builder
methods, GattService/GattCharacteristic discovery types, ATT response
parsers, ATT-over-ACL L2CAP helpers. 12 new tests (137 total btusb).
Migrate i2c-hidd from legacy ProducerHandle to InputProducer with
named producer fallback (i2c-hid), completing U3 driver migrations.
Update BLUETOOTH-IMPLEMENTATION-PLAN.md with B1/B2 completion evidence,
exit criteria assessment, and updated support language.
Add complete HCI protocol module (hci.rs) with packet types, 55+ constants,
command builders (Reset, Read BD Addr, Read Local Version, LE scan/connect),
event parsers, and structured result types. Add USB transport abstraction
(usb_transport.rs) with UsbHciTransport trait and StubTransport for testing.
Wire btusb daemon with endpoint descriptor parsing, HCI init sequence
(Reset → Read BD Addr → Read Local Version), ControllerState state machine,
and enhanced status output. Replace all expect()/unwrap() calls in btctl
and wifictl with proper error handling and graceful fallback.
91 btusb tests, 27 btctl tests, 2 wifictl tests passing.
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)
fetch.rs: use full commit hash for deterministic checkout. recipe.rs:
refactor recipe handling for cleaner patch application. sync-upstream:
add dry-run mode and improve rebase error recovery.
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.

intel-thc-hidd, i2c-gpio-expanderd, ucsid)
- Add P2-acpi-i2c-resources.patch (48KB) with all source changes
- Update ACPI-I2C-HID-IMPLEMENTATION-PLAN.md to reflect actual codebase state
