vasilito d4a6b356eb Add cmake stub for qt_internal_add_shaders in qtdeclarative
Qt6ShaderTools cmake function is not available in our cross-compilation
setup. Added -C preload with no-op stub function to allow cmake
configuration to proceed past shader compilation calls.

vasilito ae1cac1d64 Convert kwin to stub recipe with cmake configs
Real KWin build requires Qt6Quick/QML + Wayland compositor runtime.
Stub installs KWin/KWinEffects INTERFACE cmake targets, dummy
libkwin.a, and kwin_wayland wrapper script. Inspect CMakeLists
updated to remove Qml and Declarative from required components
for future real-build attempts.

vasilito 8e4b8d6107 Restore kirigami stub cmake configs approach
Qt6Quick isn't fully cross-compiled for Redox yet. Stub provides
KF6::Kirigami and KF6::Kirigami2 INTERFACE cmake targets for
downstream dependency resolution.

vasilito 449ffcafe2 Fix kf6-kdeclarative sed pattern for v6.10.0 source
The sed pattern was stale — source v6.10.0 has 'REQUIRED Qml Quick Gui'
but the old pattern only matched the previous format. Fixed to remove
both Qml and Quick from find_package.

vasilito 752bceb3e9 Enable IPv6 foundation in relibc: inet_pton/ntop, TCP socket options, DNS AAAA
Add three relibc patches (42 total) to close QtNetwork-critical socket gaps:
- P3-inet6-pton-ntop: AF_INET6 address parsing/formatting with RFC 5952
  shorthand, IPv4-mapped suffix support
- P3-tcp-sockopt-forward: forward IPPROTO_TCP getsockopt/setsockopt to
  scheme daemon instead of hitting todo_skip
- P3-dns-aaaa-getaddrinfo-ipv6: AAAA DNS record queries, lookup_host_v6,
  dual-stack getaddrinfo with sockaddr_in6 entries

Also fix P3-tcp-nodelay to use sys_call_wo + from_raw_parts (const) in the
SOL_SOCKET setsockopt fallback — setsockopt sends data to the kernel, not
reads from it.

vasilito e62acb2ebb Stabilize DRM core contracts: fix latent panics, add diagnostics and tests
Production code fixes:
- scheme.rs: replace unwrap() after checked_mul with match binding,
  eliminating a latent panic if code is reordered
- main.rs: log request context_id (PID) on request handling failure
  instead of silently discarding the error
- drivers/amd/display.rs: split silent EDID read fallback into
  separate match arms with log::warn diagnostics for short reads
  and read failures, including byte count and connector index

Test coverage:
- gem.rs: add 4 basic tests for GemManager (create+verify,
  close+verify removal, double-close error, invalid handle error)

vasilito 4e27bee9bf Retire base monolith patch in favor of 27 individual P2 patches
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.

feraiseexcept, fesetenv, fesetexceptflag, fesetround, fetestexcept,
feupdateenv) with proper MXCSR and x87 CW register access.

P3-sched: 6 scheduler functions (sched_get_priority_max/min,
sched_getparam, sched_rr_get_interval, sched_setparam,
sched_setscheduler) with EINVAL for bad policy and no-op validation
since Redox has no real-time scheduler.

vasilito 58edf0df0b Add kded6 recipe and rewrite kirigami for real Qt6Quick build
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.

vasilito 38013bbf16 Wire evdevd input devices into udev-shim and enable udev in libinput
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.

vasilito 843f30ba42 Fix relibc netdb/lookup: use-after-move and unsafe block errors
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.

vasilito f665929d96 Fix redbear-sessiond Redox shutdown: remove unreachable code after tokio::select!
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.

vasilito 61e1a1335c Migrate all init scripts from legacy format to .service TOML units
Convert 14 config files from the legacy init script format (plain-text
commands) to the systemd-style TOML .service format. The init daemon
supports both formats; this eliminates the legacy path entirely so that
all services use the richer, more structured TOML unit format.

Key changes per config:
- base.toml: split 00_base into 00_base.service (tmpdir) + 00_sudo.service
  (sudo daemon); remove redundant 00_drivers and 10_net (handled by
  existing .service files from the base recipe)
- minimal.toml: split 30_console into 29_activate_console.service +
  30_console.service + 31_debug_console.service
- desktop-minimal.toml: convert 20_display and 30_console to .service,
  add 29_activate_console and 31_debug_console overrides
- x11.toml: convert 10_dbus, 10_xenv, 20_orbital, 30_console
- redoxer.toml: split 10_net into 10_smolnetd.service + 10_dhcpd.service,
  convert 30_redoxer
- redbear-legacy-*.toml: update override references to .service paths
- acid.toml, auto-test.toml, os-test.toml, sys-build.toml: direct conversions

  bitmaps, key/led state tracking, abs_info defaults/overrides,
  bitmap_from_codes edge cases)
- udev-shim device_db.rs: 13 tests (DeviceInfo construction, subsystem
  naming, id_path formatting, input kind detection, property formatting
  for GPU/keyboard/mouse, device_info/uevent output, PCI fallback)
- firmware-loader scheme.rs: 20 tests (openat validation, read offsets,
  fstat/fsize, EROFS enforcement, mmap_prep bounds, mmap/munmap/on_close
  deferred cleanup lifecycle)

Total: 65 evdevd, 15 udev-shim, 24 firmware-loader — all passing.

GattDiscoverChars, GattReadChar, GattServices, GattCharacteristics)
with ATT-over-ACL transport. Wire HciBackend::read_char to perform
real GATT workflow through scheme filesystem (discover services →
discover characteristics → read value) instead of hardcoded stub.

disconnect). Add hci_backend.rs to btctl implementing Backend trait via
scheme filesystem reads/writes instead of stub data. Backend selection
via REDBEAR_BTCTL_BACKEND=hci env var, StubBackend remains default.

Fix daemon_main to use correct redox-scheme 0.11 API (Socket::create,
next_request/handle_sync/write_response loop) instead of non-existent
SchemeBlock.

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.

vasilito 183354fcb1 Fix pcid crash: pass valid INIT_NOTIFY pipe from hwd
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
