Classify configured devices by keyboard and pointer capability so
automatic keyboard capture leaves relative pointer devices with the
display server.
Run descriptor, grab, physical-state, and LED operations on one worker.
Marshal normalized events through each display server's event loop and
serialize ownership changes with per-lane barriers.
Fall back whole lanes to native input when an evdev cohort cannot be
owned, and retry missing or removed devices without disabling the rest.
Handle report framing, SYN_DROPPED, high-resolution wheels, queue
overflow, held-state cleanup, and guest-driven keyboard LEDs. Restore
host LEDs and kernel grabs during teardown.
Re-evaluate capture when the active input transport changes.
Allow display servers to dispatch a caller-owned event source on their
native event thread. This lets background input readers marshal events
to the thread that owns application and display-server state.
Poll X11 fairly when native events remain continuously available, and
use bounded polling if the external descriptor cannot be registered.
Report guest HID keyboard LED state from LGInput to LGIdd and
publish it with the LGMP input endpoint status.
Forward SPICE modifier updates through the same provider state so evdev
can synchronize physical keyboard LEDs across transport changes and
reconnects.
Bump the versioned pipe and KVMFR input status contracts for the new
feedback state.
Accept earlier LGMP input status versions without LED feedback so the
client retains input while the guest driver is being upgraded.
Add a configured escape key plus Shift+R command that requests display
recovery from the LGMP transport and switches video to SPICE.
Track the request on the main thread, report its asynchronous result,
and return its producer instance with the request serial for exact
correlation.
Preserve normal escape+R rotation behavior, including custom Shift
escape keys.
Mark the last non-empty FILE_DATA payload with BEGIN and END when the
producer knows it is terminal. Complete producer bookkeeping in the
following fileDataEnd call without consuming another LGMP grant. Keep
the standalone terminal record for empty and legacy unknown streams.
Drain up to 64 queued clipboard records per worker pass instead of
sleeping after every message. Poll at 1 ms while transfers, blocked
writes, held input, or pending output are active, and retain the 10 ms
interval while idle.
This removes a serialized grant round trip from every non-empty file
response and reduces scheduling delay while a large transfer is active.
Keep the 1 MiB payload size because the bottleneck was stop-and-wait
latency, not the chunk capacity.
Exercise a full 1 MiB response in a single BEGIN|END grant and retain
coverage for empty unknown-size responses.
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.
