Move the reusable named-pipe endpoint and shared support code into
the LGCommon static library.
Run a dedicated server in LGIdd and a reconnecting client in
LGInput, with device-lifecycle handling and report framing.
Refactor the helper pipe to use the same endpoint implementation.
Build LGInput as an independent UMDF driver with its own entry point,
service, tracing, and binary.
Expose absolute pointer, relative mouse, and keyboard collections with a
guarded report queue.
Keep LGIdd as the startup and deployment project. Give it a non-linking
build/package dependency on LGInput so F5 stages both driver stacks and
installs them together through LGIddInstall, while the two UMDF binaries
remain independent for future IPC.
Stage both DLLs for the NSIS installer, retain the WDK UMDF remote-debug
startup attachment, and move CSRWLock into LGCommon for the input
driver's report queue.
Run CTest directly in every client matrix job so each build is tested
without waiting for the full matrix to complete.
Install the Mesa runtime in the build job, preserve failure artifacts,
and remove the archive transfer and duplicate test job.
Hide the startup splash immediately after overlay initialization when a
render-pipeline capture is requested. This occurs before the frame
thread is released, so no EGL surface buffer can contain splash pixels.
Add a configurable stride to the synthetic transport and poison row
padding so incorrect row addressing is visible in captured output.
Cover full-frame and moving-damage BGRA uploads with 512-byte and
5120-byte pitches, and verify the advertised layout in the log.
Use an explicit placed buffer for software frame copies so the D3D copy
uses the same row pitch published through KVMFR.
GetCopyableFootprints describes buffer copies and cannot be used to infer
the physical layout of a placed row-major texture. This caused padded
resolutions to use the wrong row starts in every consumer.
Keep the copy direct to IVSHMEM without a staging or CPU copy.
Move cadence and pipeline declarations under capture, and move local
named-pipe handling under ipc.
Flatten display contexts and rename files after their contained classes.
Keep transport headers limited to transport contracts and capabilities.
Consolidate CSwapChainProcessor definitions so each source file matches
the class it implements.
Introduce transport, frame, and control interfaces with an LGMP factory
backend.
Move LGMP and IVSHMEM implementation details under transport/lgmp and
expose direct frame-buffer memory through a neutral capability.
Group the IDD sources and Visual Studio filters by subsystem.
Split the device and swap-chain implementations into focused units,
rename the context classes, and reduce header coupling.
Move cadence-aware hardware capture and immediate software capture
behind a common frame processor interface.
Keep shared damage tracking and frame-buffer ownership in the base
processor, and move stateless format, resource, and rectangle helpers
into CFrameProcessorUtil.
Decouple frame-buffer resources from CSwapChainProcessor by passing the
device dependencies they use directly.
Bypass cadence retention when the software render adapter is active.
Publish each available source frame immediately with one damage-aware
D3D copy into its final IVSHMEM resource.
Keep only one software copy in flight so newer frames are dropped
instead of queued behind stale work. Retain accumulated damage for the
next frame and skip static re-encodes when no image update is pending.
Use a row-major IVSHMEM texture when the shared heap supports it and
fall back to a direct IVSHMEM buffer copy otherwise. In indirect mode,
copy only damaged rows from readback memory into IVSHMEM.
Store refresh rates in millihertz and preserve three decimal places.
Advertise exact rational rates while accepting legacy integer values.
Accept rates from 23.900 through 1000.000 Hz.
Rebuild the driver's cached mode list before replugging the monitor so
Windows enumerates the settings saved by the helper.
Keep saved mode refresh rates intact and update only ExtraMode to the
configured default refresh.
Keep the tracked Wayland hardware position sourced only from absolute
wl_pointer events. Relative motion remains unclipped at output edges,
so accumulating it made the client believe the hardware cursor had
reached the guest position and caused the corrective warp to be
skipped.
Keep cursor coordinates in shape-origin form after absolute
realignment. Preserve the logical hotspot when a shape-only update
changes its hotspot, preventing either path from leaving a permanent
offset.
Center the Wayland diagnostic cursor on its actual pointer hotspot and
preserve it while cursor themes are reloaded for output-scale changes.
Round fractional guest positions to the nearest logical pixel instead of
biasing synchronization toward the top-left corner.
Resynchronize the hardware pointer when a cursor shape changes its
hotspot. Only perform the extra synchronization when the hotspot
actually changes, and update the basic-mode projection at the same time.
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.
Reseed the synthetic Present target window when compositor MSC advances
outside the queued range. This prevents a long compositor stall from
permanently exhausting JIT cadence callbacks.
Mark the recovery sample as discontinuous so calibration does not treat the
MSC jump or completion burst as renderer skipping.
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.
Keep one accepted frame-schedule control in flight until LGMP reports
that its serial has been consumed. Retain ambiguous tokens across pointer
queue recovery instead of retransmitting RESET or IMMEDIATE messages.
Back off acknowledgement polling and definite enqueue failures. Use modular
serial comparison so acknowledgement remains correct across rollover.
Permit retained-buffer reuse when both private queues are occupied by a
previous timing owner, even if the new owner has no pending deliveries.
Use the shared fallback when possible. Otherwise retain the fresh frame
locally and republish it instead of waiting for stale private deliveries.
Replace the oldest provisional schedule entry when the bounded client
table has no empty slot. Never evict a client whose frame subscription has
already been observed.
This prevents rapid failed reconnects from filling every scheduler slot
before a real frame subscriber can be registered.
Keep preparing the newest frame when both private owner lanes remain
referenced by a non-consuming timing client. Reuse only an unreferenced
completed buffer and continue serving eligible shared subscribers.
Track owner delivery separately from local retention so cadence advances
without acknowledging owner delivery or accepting phase feedback. Republish
the newest completed frame as soon as an owner lane becomes available.
Record every requested recipient after LGMP posts to at least one live
subscriber. Targets that disappeared during the post are harmless, while
surviving targets must advance instead of remaining perpetually due.
Consume subscription notifications from the private owner queues. When
any lane gains a subscriber, request a retained-frame publication for
the current timing owner so a static desktop cannot leave it waiting.
Renew frame scheduling only while the source is active and OBS is
delivering video ticks. Release ownership after deactivation or a stale
tick stream.
Reacquire with a new generation and an immediate frame when ticking
resumes.
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.
Advance past cadence deadlines whose publication targets have already
expired after a completed periodic frame.
Use the same slack, work, and safety lead as target selection so the next
publisher wait cannot immediately expire again.
Request one static-desktop re-encode and inspect repeated presentation
numbers for its empty dirty-rectangle marker.
Prepare every marker in a free candidate without superseding retained
damage, so the last desktop update survives a late copy failure.
Replace the shared force and republish booleans with request tickets.
A completed publication now acknowledges only requests captured when it
began, so a concurrent immediate or cadence-break request survives.
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.
Track the newest submitted and completed frame independently. Only
retain or replay a frame after its copy callback succeeds.
Keep the prior completed frame when a newer copy fails, and compare
publication sequences so out-of-order callbacks cannot move backward.
Treat a forced publication as periodic once the normal pre-deadline
send point is due. This prevents an immediate forced copy from being
followed by another copy for the same cadence slot.
Check a busy slot fence before waiting for its thread-pool callback.
This lets the caller complete finished GPU work inline and avoids a
scheduler delay before the allocator and command list can be reused.
