A stable clock model can request a negative recovery slew while the
unbounded ring is physically underrun. This leaves the reader ahead of
the writer indefinitely and outputs silence until playback is restarted.
Floor active recovery at the physical low-water requirement. Rebase the
device-clock phase by any extra refill so modeled latency remains at the
target without restarting the underrun correction cycle.
Add a deterministic regression for negative physical debt opposing the
stable clock model.
Do not treat the capacity of an allocated PipeWire buffer as the
requested playback period when PipeWire supplies no per-buffer hint.
Use the current stream quantum when available and fall back to the
configured period.
Count one underrun per starvation episode and end the sync diagnostics
epoch when a logical source stops.
Resume a compatible backend synchronously so data after a same-wire
restart is accepted immediately. Rebase the first post-idle device tick
without passing a long gap through the short-step clock filter.
Cancel in-flight backlog trims before fresh audio can be queued.
Recover stable local playback in the device clock domain and restart
rate control from the measured feed-forward clock ratio.
Ignore catch-up packet sizing until the normal source cadence returns.
Do not learn late delivery from packets that already caused an
underrun and media-clock rebase. Preserve learned jitter only across
continuous playback.
Cache native keyboard lock state across input-provider transitions and
reconcile it with HID LED feedback over LGMP.
Project raw and corrective lock-key transitions through the reliable
input FIFO, defer correction until outstanding transitions settle, and
recover from delayed or missing feedback without double toggling.
Do not publish the default all-off LED value until Windows supplies a
real HID output report. Treat the first all-off report as valid and
retain known state across pipe reconnects.
Serialize feedback processing with connection invalidation so a stale
message cannot restore validity after disconnect.
Advertise PNG offers as delayed CF_DIBV5 data while retaining the
registered PNG representation. Decode requests with the native WIC
PNG decoder so applications that only accept DIB formats can paste
the image.
Retain non-file clipboard representations while asynchronous file MIME
imports are validated. If an offered URI list is invalid or cannot be
read, publish the retained image and text formats instead of clearing
the clipboard.
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.
Capture-on-focus could consume the initial focus event before an input
provider became available. The focused state then suppressed any later
attempt to establish capture.
Treat explicit capture as local window state, refresh keyboard ownership
on focus and input-policy changes, and preserve pre-ungrab availability
for key release. Fall back to the window center when guest cursor
geometry is not ready.
The interactive Helper can start when the console user token exists but
before WinSta0\Default is ready. SetDisplayConfig then returns
ERROR_ACCESS_DENIED while recovery exit caches the failure and keeps
topology enforcement suppressed.
Keep the recovery request pending while desktop access is transient.
Move the pipe worker to the input desktop and retry without caching
intermediate failures. Leave an exhausted access failure uncached so a
later replay can recover.
Restore the periodic enforcement timer and retry topology without
reapplying a display mode that Windows has already accepted.
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.
When LGIddHelper is unavailable, recovery requests could remain
pending until timeout while the virtual monitor stayed connected.
This could leave a logged-out guest without a usable display.
Fall back to departing the IDD monitor for active recovery, then
re-arrive it before normal recovery completes. Serialize monitor
lifecycle changes and preserve recovery ordering across Helper
reconnects, timeouts, and stale responses.
