redox-drm = "ignore" was left from earlier GPU-suppression tests.
Restored to active so the DRM/KMS display driver is included in
the full ISO image. Without it, no GPU output or SDDM compositor.
VIRTGPU_GETPARAM: expand from 1 to 8 sub-parameters for Mesa
compatibility. Mesa virgl driver probes CAPSET_QUERY_FIX,
RESOURCE_BLOB, CONTEXT_INIT, SUPPORTED_CAPSET_IDS, and
EXPLICIT_DEBUG_NAME during initialization.
set_property: add doc comment explaining that virtio-gpu has
no per-object property tables — all mode/fb/active changes
flow through atomic commit, not set_property.
cursor_move: replace x.max(0) as u32 / y.max(0) as u32 with
explicit if-else for clarity. Negative coordinates now clamp
to zero at screen edges (same behavior, more readable code).
Extract protocol-agnostic FenceTimeline from Intel to shared
src/drivers/fence.rs — atomic-based fence tracking suitable
for Intel, VIRGL, and AMD drivers.
Extract protocol-agnostic SyncobjManager from Intel to shared
src/drivers/syncobj.rs — syncobj create/destroy/signal/reset/
wait/query and sync_file fd export/import.
Wire both into VirtioDriver:
- Add FenceTimeline + SyncobjManager fields
- Implement all 5 GpuDriver syncobj trait methods
(create, destroy, wait, export_fd, import_fd)
- Track fence seqnos in virgl_submit_3d (allocate
before submit, signal after completion)
Intel fence.rs and syncobj.rs converted to thin re-export
modules pointing at shared sources — no behavioral change
for Intel driver.
This gives Mesa VIRGL userspace the standard DRM syncobj
API for GPU/compositor synchronization.
29_activate_console: changed from oneshot back to oneshot_async.
The oneshot type calls child.wait() which blocks the entire init
scheduler. If inputd doesn't drain its control channel promptly,
ControlHandle::write() hangs forever, freezing boot.
30_console: added 'sleep 0.2' before 'exec getty 2' to give
inputd time to process the VT activation before getty opens
/scheme/fbcon/2. Eliminates the race condition without
blocking the init scheduler.
Kernel has a use-after-free bug in sys_read triggered by /scheme/sys/msr
access. The probe guard prevents most crashes but the kernel bug can still
trigger during MSR read paths. Removing the MSR fallback eliminates this
crash path entirely. Vendor detection now uses /scheme/sys/cpu only.
The cross-compiler's GCC built-in stddef.h is blocked by relibc's
_STDDEF_H guard, causing size_t/off_t/ptrdiff_t to be undefined.
Add fix_types.h with guarded typedefs and force-include via CPPFLAGS.
Also: comprehensive upstream relibc comparison for systematic import.
Remaining: redoxer env overrides CC, injecting broken stdint typedefs
from its toolchain. This needs a redoxer-level fix to clean the
injected flags before passing to build commands.
coretempd uses syscall::call::write() for init notification, which
sends raw bytes — not an fd transfer via CallFlags::FD that the Scheme
init type expects. Changing to Scheme would cause init to block forever
in call_ro waiting for an fd that never arrives in the expected format.
The oneshot_async + resilience pattern is correct for coretempd.
- 29_activate_console.service: oneshot -> oneshot_async (unblocks init
scheduler, enabling getty 2 -> login)
- 15_coretempd.service: oneshot_async -> {scheme="coretemp"} (init
now correctly registers the scheme fd)
- cpufreqd: child-process MSR probe detects QEMU's lack of MSR 0x199
and gracefully degrades to monitoring-only mode
- coretempd: notification failure is now non-fatal (WARN instead of ?)
- driver-manager: "no match entries" downgraded from warn to debug
(infrastructure daemons intentionally have no hw match)
- 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.
- 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.
New local recipe coretempd reads IA32_THERM_STATUS MSR via the
new sys:msr scheme and exposes per-CPU temperatures via scheme:coretemp.
- Reads IA32_THERM_STATUS (0x19C) and IA32_TEMPERATURE_TARGET (0x1A2)
- Calculates Celsius from digital readout relative to TjMax
- Exposes /scheme/coretemp/ directory with per-CPU temperature files
- Added to redbear-mini.toml (inherited by redbear-full)
- Added 15_coretempd.service init file
Add P0-disable-qml-quick.patch for building KWin without QML/Quick
dependencies. Update greeter scripts to prefer kwin_wayland. Enable
kwin in redbear-full config.
