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.
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.
I think "server" and different "implementations" of it makes it a lot clearer
to readers that it's a swappable thing that can serve multiple clients without
being too much jargon.
Treat autoCapture as keyboard ownership while the pointer is inside the
guest viewport. Predict the next local position for both absolute and
relative motion, then release the keyboard before the pointer crosses
an edge.
Keep capture, focus, and deferred evdev transitions consistent while
retaining the latest local position as the prediction baseline.
Add an opt-in USB audio fallback and connect the emulator to an
available PureSpice USBREDIR channel.
Keep transport-provided audio in priority and serialize USB parser
processing and teardown on the PureSpice thread.
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.
Coalesce pointer updates to the nominal output cadence instead of
waking the renderer for every transport packet. Keep request and
presented generations separate so updates racing a render receive a
trailing swap.
Let JIT consume cursor changes on display callbacks to preserve VRR
cadence, and use a deadline worker for non-JIT rendering. Give normal
source frames a short grace period so an on-rate feed absorbs the
cursor update instead of producing an extra swap.
Repaint visibility and cursor-content changes even when movement
redraws are disabled, including the transition that hides the cursor.
Model playback latency from the device period, arrival jitter, source
packet phase, and resampler delay. Treat audio:latencyOffset as an
explicit addition to this minimum and align the first device pull to
the next packet deadline. This starts playback near its steady-state
target without unnecessary prefill or startup underruns. Use a
512-frame default period as a practical low-latency baseline.
Replace the startup clock hold with a one-sided proportional
acquisition controller, then hand off to source/device rate
feed-forward and a slow phase loop. Calibrate the logical device
timeline at handoff, discard correction that opposes the current
error, and slew-limit rate changes. This prevents startup drain,
integral wind-up, overshoot, and long convergence while preserving
clock-drift compensation.
Allow audio backends to expose a real-time resampler and use
PipeWire's adaptive resampler when version 1.4 or newer supports it.
Retain libsamplerate as the fallback and add audio:resampler to select
the implementation. Wait for PipeWire stream setup to complete and
propagate rate-control failures cleanly.
Track PipeWire input-consumption and output-equivalent clocks
separately. The input clock measures ring latency while the output
clock drives feed-forward using the ratio that governed each request.
This removes delayed self-feedback that made adaptive resampling
oscillate between the correction limits.
Reduce audio:debug output to useful latency, clock, jitter, and xrun
values, and scale the playback graph from the startup estimate. Update
the option names and documentation for the new latency model.
