Apply the same sampling margin to swap damage as buffer-age repair and
clip reported rectangles to the EGL surface. This ensures compositors
update every pixel affected by scaling or filtering.
Invalidate in-progress swap chain setup when IddCx unassigns the
monitor, and serialize replacement assignments so workers are
never started on abandoned handles.
Also initialize all worker dependencies before starting the processing
thread and treat teardown during SetDevice as normal cancellation.
This commit turns the icon handling into using a macro so we don't need to do
weird conversions from unsigned long (needed by X11) to uint32_t (needed by
Wayland).
Also simplified the error handling path on Wayland.
Preserve the requested display mode across intermediate swap chains when
rapid resolution changes cause replugs to be coalesced. Apply and clear
the mode only once the final replacement swap chain is ready.
Keep the replug lifecycle gated until the old swap chain has drained and
released its pending frame, and the replacement swap chain is fully
initialized. Coalesce additional requests into a follow-up replug to
prevent overlapping topology changes and IddCx release-frame timeout
bugchecks.
Drop frames when the LGMP queue is full instead of blocking
while holding an IddCx surface. Always finish every
acquired frame, including duplicate frame numbers, so
replug teardown cannot trigger the release-frame watchdog.
Render ImGui to an intermediate SDR framebuffer and map it into the
native PQ or scRGB output using the Wayland surface reference white.
Preserve premultiplied alpha during conversion and limit composition to
damaged overlay regions.
Generate the EDID once during adapter initialization and update only the
live mode list when resolutions change.
Changing the EDID during a monitor replug causes Windows to identify it
as a different monitor, losing the existing display configuration.
Reusing the original EDID preserves the monitor identity while still
allowing dynamic modes to be advertised through IddCx.
LGMP session validation may wait 500 ms for the shared-memory heartbeat
to advance. Run it on a worker so Wayland input remains responsive while
preserving stale-data detection.
Match the EGL client’s DRM formats, use implicit linear modifiers, and
reset cached imports safely across format changes and restarts. Fall
back to CPU upload if either DMA buffer cannot be imported.
Submit the D3D12 copy before exposing the frame through LGMP, preventing
clients from waiting on work that has not yet been queued. Track the
last published buffer separately for safe subscriber resends and handle
submission failures.
Build the active filter chain only when its configuration changes,
including filter settings or order, input format, dimensions, output
size, and DMA mode.
Unchanged frames now execute only the cached active filters, avoiding
repeated setup, preparation, and output-resolution queries.
Reconfiguration forces a full-frame pass to prevent stale intermediate
framebuffer contents.
Also refresh CAS and FSR uniforms when loading presets and move
downscale pass selection out of the per-frame path.
Track context-local GL bindings to avoid redundant program, framebuffer,
buffer, texture, sampler, viewport, blend, and scissor state changes.
Invalidate the cache across context switches, ImGui rendering, and
shared object changes. Preserve CPU-backed texture upload correctness by
explicitly clearing pixel unpack buffer bindings where required.
This reduces hot-path driver overhead without adding waits or GPU
synchronization.
Track PBO fences per upload slot and wait only when a slot is reused,
allowing rendering to proceed without a CPU stall. Use GPU-side waits
for cross-context DMABUF synchronization.
Also propagate KVMFR write-completion failures so incomplete
shared-memory frames are never submitted, while retaining incremental
damage-copy waits to avoid added latency.
Replace the per-frame uniform list with stable, name-cached handles that
retain their values across shader recompilation. Track dirty uniforms so
only changed values are uploaded, reducing redundant GL calls and buffer
management.
Add a reusable effect-pass pipeline with per-pass shaders, samplers,
formats, resolutions, and intermediate render targets. This makes
external effects easier to integrate and supports arbitrary multipass
chains.
Migrate the desktop, cursor, damage, 24-bit, downscale, CAS, and FSR
rendering paths to the new APIs. Also ensure framebuffer objects are
released correctly.
