Wave 1 (linux-kpi drm_shim.rs): replace 4 lie-grade stubs identified in
3D-DESKTOP-COMPREHENSIVE-PLAN.md §3.4.
- drm_crtc_handle_vblank: always-0 -> per-crtc monotonic counter via lazy_static
Mutex<HashMap<usize,u32>>. Mesa/KWin no longer stalls on the first
page-flip wait (audit §2 #6).
- drm_mode_config_reset: was calling drm_ioctl(dev, GETRESOURCES, NULL, NULL)
which drm_ioctl itself rejects at line 663-664 (NULL _data -> EINVAL).
Replaced with a logged no-op; redox-drm maintains mode state per-open.
- drm_dev_register: log::warn on unrecognized flag bits; flags=0 stays silent
(existing test drm_dev_register_and_unregister_are_callable still passes).
- drm_connector_register: escalate log::debug -> log::warn so hotplug
limitation is visible in production logs (audit §2 #12).
Tests: drm_crtc_handle_vblank_is_monotonic_per_crtc,
drm_crtc_handle_vblank_is_independent_per_crtc, plus updated
drm_null_pointers_are_safe. cargo check --lib clean.
Wave 2 (SDDM): both redox-virtualterminal-stub.patch and
redox-helper-utmpx-stub.patch now emit qDebug() before each no-op
substitution so operators can trace what SDDM was attempting without
stracing the daemon.
Wave 3 (redbear-sessiond): Manager interface now emits SeatNew
(org.freedesktop.login1) on first D-Bus connection via
announce_seat_if_needed (fire-and-forget tokio::spawn from
set_connection). Idempotent via Arc<AtomicBool>. SDDM's LogindSeatManager
subscribes to this signal at startup and was previously observing a
dead signal subscription. emit_seat_removed exposed for future use.
Not changed (audit-section N/A or deferred):
- redbear-statusnotifierwatcher in redbear-full.toml: already wired
at line 233 with activation file staged (audit §3.7 was outdated).
- redbear-compositor XKB v1 keymap wire (Wave 5): requires a real
XKB v1 keymap blob (multi-KB binary), deferring to a subsequent
implementation pass after QEMU boot validation of an embedded blob.
