Keep guest-to-host pointer synchronization active while an attempted
surface exit is blocked by the edge of a Wayland output. Continue
forwarding relative motion and wait for wl_pointer.leave before marking
the cursor outside the window.
Distinguish whole-surface releases from exits into letterbox space so
the expected asynchronous release callback cannot disable the feedback
loop before the pointer is confined again.
Treat Wayland pointer capability loss as a real leave so an unrelated
inactive callback cannot be mistaken for the intentional release.
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.
Pointer updates bypassed the paced overlay render and woke the renderer
for every cursor packet. On the default single-buffer EGL surface,
each full fade redraw could expose the desktop before the splash was
blended again.
Coalesce pointer redraws into the existing fade cadence while keeping
the latest cursor state. Immediate cursor redraw resumes when the fade
ends.
Restore client and test files that were already staged when the OBS
cadence commit was created. Keep that work out of the scheduler series
while leaving its working-tree contents untouched.
Track the LGMP serial for each accepted frame-schedule message and wait
for its acknowledgement before sending another. Preserve pending RESET,
IMMEDIATE, and feedback state after definite enqueue failures.
Use bounded retry polling and request one fresh immediate frame after an
ambiguous pointer-queue fault recovers.
Renew the frame-schedule lease only while the display server is
producing real cadence callbacks. Release ownership after the cadence
stalls, and reacquire with an immediate reset when it resumes.
For non-JIT rendering, treat only a successful presentation as live
cadence.
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.
Only report the client queue lead when JIT rendering provides a valid
measurement. Clamp linear phase errors instead of wrapping them into the
opposite direction at half of a refresh period.
Timestamp OBS frames after the shared framebuffer becomes ready.
Always track Wayland surface outputs alongside fractional scaling and use
RandR modes for X11 cadence. Remove render-derived feedback so a
throttled client cannot teach the producer to remain throttled.
Release scheduling after nominal output timing remains unavailable.
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.
Treat every completed swap as satisfying the interactive overlay
refresh requirement. Only force a JIT overlay render after the 60 Hz
deadline, and rearm the timer-based deadline after frame-driven swaps.
This prevents interactive overlays from adding redundant swaps when
incoming frames already keep the client at or above the required rate.
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.
Move shared-memory ownership, LGMP session handling, queue access, and
DMA setup behind a transport interface. The LGMP backend preserves the
existing zero-copy frame and DMA paths while owning its lgmp:* options.
Expose the initialized EGL context through a versioned renderer interop
record for future accelerated decode backends. Add an LGMP-independent,
deterministic test transport for graphics-pipeline validation.
Queue the display-server surface format while the renderer lock still
serializes the matching onFrameFormat update. This prevents the render
thread from presenting a frame in a new HDR encoding before the Wayland
image description transition has been queued.
Request true floating-point EGL configs for scRGB and expose the native
encodings supported by the selected surface. Fall back to software HDR
mapping when the surface cannot represent the incoming wire format.
Resample PQ in linear light, keep SDR-only effects out of native PQ
chains, and consume the cursor-specific white level without changing
binary monochrome cursor mask operations.
