Track unexpected loss of an admitted fallback independently from normal
stop and UUID revocation. Terminate once both primary and fallback
sessions have disappeared, regardless of notification order.
Make shutdown terminal so concurrent disconnect handling cannot replace
it with restart or running state.
evdev_stop was never called, and calling it revealed unsafe teardown:
the device list was freed before the thread was joined, a zero epoll
descriptor was mistaken for a valid one, and the device loops walked
past the end of the array through a sentinel that does not exist.
Join the thread in evdev_stop and defer the rest to the new evdev_free.
The display server grab hooks route into evdev until its event thread
is joined, so the device state must stay valid until the display
server has been freed; evdev_free then restores the hooks and releases
the state.
Report expected and current protocol versions through the transport
interface and expose session-independent recovery operations.
Offer recovery from the version mismatch popup, publish requests through
the reserved IVSHMEM channel, and select the validated SPICE fallback.
Register SPICE connection and component options in the SPICE transport.
Move generic input and clipboard settings out of the SPICE namespace,
while retaining migration aliases for existing configurations.
Keep PureSpice and usbredir build requirements private to the transport,
and remove obsolete SPICE configuration state from the client core.
Track primary and fallback video with source-specific generations, and
publish a source only after its first frame or software surface is
ready.
Route SPICE surfaces and cursors through the generic render queue. Keep
the current image across handoffs, and switch input only after the new
source has been presented.
Move fallback activation to its worker so display callbacks cannot
block or deadlock the render path.
Rework audio provider and backend lifecycles so playback and capture
callbacks quiesce without blocking real-time threads. Move activation,
teardown, controls, retries, and diagnostics onto bounded workers.
Harden USB audio cadence, feedback, and capture recovery.
Preserve source clocks through recording and pace packets from the
device clock. Bound queues, waits, conversion buffers, and packet sizes.
Make PipeWire and PulseAudio stream control thread-safe and recoverable.
Correct latency clock domains, coalesce rate updates, preserve recent
capture under overload, and keep logging outside real-time callbacks.
Add a composite UAC2 microphone function with its own clock so
recording and playback can use independent sample rates.
Packetize asynchronous capture through usbredir, follow the host
capture clock, and preserve the newest frames across stalls.
Reconfigure active recording without another permission prompt and
fix lost PipeWire capture wakeups.
Advertise an asynchronous UAC2 OUT endpoint with explicit feedback so
Windows paces USB audio from the host playback clock.
Drive feedback from measured backend consumption plus the existing
buffer phase controller. Preserve the local and backend resampler paths
for providers without active feedback.
Keep audio diagnostics in the correct clock domains, report ring and
backend latency separately, and avoid hot-path feedback wakeups.
Route clipboard exchange through a provider interface. Connected
transports take priority while SPICE remains the fallback.
Track asynchronous X11 and Wayland transfers by request, preserving
clipboard ownership across provider changes.
Use PureSpice clipboard status notifications for capability and
lifecycle updates.
Route audio through a provider interface. Connected transports take
priority while SPICE remains the fallback.
Carry explicit sample formats, rates, channel layouts, and source clocks
through playback and recording. Add optional presentation clock feedback
for active synchronization.
Remove the persistent confined-pointer workaround that emulated cursor
warping on Wayland. Normal pointer motion now uses absolute input only.
Create relative and locked pointer objects only during capture. Preserve
the request across pointer capability changes, and suppress relative
events until the compositor confirms the lock.
On uncapture, publish the current absolute position instead of trying to
warp the host cursor.
Map the remaining Linux mouse buttons through Wayland and evdev.
Use one X11 translation for cooked and raw press and release events.
Ignore unsupported horizontal scrolling and extended SPICE buttons.
Use the LGMP input queue when the host advertises transport input,
while preserving SPICE fallback through the existing input abstraction.
Claim input lazily, publish ordered full-state keyboard and mouse
reports without blocking rendering, and keep the owner lease alive.
Reserve queue capacity for discrete transitions, coalesce only motion
under pressure, and release ownership safely during idle and disconnect.
Keep the Linux-to-HID map in the client and update LGMP to the
nonblocking data-send API required by the input worker.
Introduce LG_InputOps and route keyboard and mouse input through the
active video transport when it provides an input backend.
Keep SPICE as the fallback and force it while the SPICE display is
active. Add atomic shared/exclusive locking for safe backend changes.
Track cadence, interruption, and calibration wake reasons independently
across X11 and Wayland. Feed phase correction back only when a pure
cadence wake renders the exact frame that was queued at that wake.
Propagate EGL swap results through the display-server boundary. Reject
failed presentations and keep pending Wayland HDR descriptions inactive
until the preceding surface commit succeeds.
Bump KVMFR to version 28 and attach generation, epoch, and deadline
identities to cadence deliveries and their timing records.
Accept phase corrections only for the exact completed publication. Keep
VM and client clocks independent by exchanging relative phase errors.
Make submission, completion, and work-estimate accounting best effort
so scheduler state cannot delay GPU submission or frame publication.
Copy imported IVSHMEM frames into renderer-owned textures before
acknowledging their LGMP messages. Hold each lease until its copy fence
signals, and protect selected snapshots until rendering completes.
Track independent delivery lanes, drain acknowledgements on the frame
thread, and recover stale queue subscriptions after host timeouts.
Move splash transitions onto the render thread and derive opacity from
elapsed monotonic time. Pace active animation at a display-compatible
minimum of 60 Hz while allowing incoming frames to satisfy that demand.
Reset the splash cleanly across reconnects and latch state changes with
the full-frame restoration decision.
Mark the active fade as requiring a fully restored render target.
This also covers guest-driven renders between animation ticks so they
cannot blend over stale splash content.
Correlate received frames with the texture update actually consumed by
the renderer and retain damage until its token becomes renderable.
Split client latency into dispatch, import, queue, preparation, setup,
effects, desktop, composition, and swap stages in FRAME LATENCY.
Exclude diagnostic overlay work from composition and preserve client
wait time when producer timing is unavailable.
Publish joined samples through a bounded token queue, avoid sleeping
while producer timing is finalized, and correct Wayland photon units.
Add an optional EGL framebuffer capture path for the test transport.
Capture the fully composed frame before presentation and retain its
surface format and HDR state for validation.
Add GoogleTest integration tests which run the production client
under a headless Weston compositor and compare every output pixel
against an independent reference implementation.
The matrix covers BGRA, RGBA, BGR32, RGB24, PQ RGBA10 and scRGB
RGBA16F with full, moving, overlapping, maximum-count, invalid, null
and zero-area damage rectangles. Validate HDR-to-SDR conversion and
native HDR output metadata when supported by the compositor.
Keep tests opt-in through ENABLE_RENDER_TESTS and document how to run
the software and native HDR tiers.
