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 retained frame candidates in the final linear transport layout.
Prepare texture output in local DEFAULT buffers before cadence holding.
Then publish full frames with a single buffer copy.
Keep partial damage on matching pitched layouts and leave effect-owned
buffer copies unchanged. This moves detiling out of the
deadline-critical IVSHMEM or readback transfer.
Replace the texture-shaped RGB24 output with a linear raw buffer and
keep its packing, damage translation, and buffer copies inside the
RGB24 effect.
Benchmark full-frame native and packed processing and retain the faster
path for each source format. Preserve logical damage rectangles for
client updates and alternating framebuffer repair.
Return compute outputs to COMMON for COPY queue handoff and refresh
cached framebuffer sizes when switching packed and native layouts.
Give each in-flight framebuffer a complete post-processing chain and
its own COMPUTE recording slot while retaining one physical queue.
Claim framebuffer ownership before submitting compute work, and use
the frame index for both COMPUTE and COPY recording state. Drain
in-flight work before reconfiguring either chain so COPY never
references replaced effect resources.
Require both chains to contain the same effects, preserve pending
damage, and release ownership on every pre-copy failure path.
Honor the IddCx 3x4 XYZ matrix and post-transfer LUT in the IDD
conversion pipeline. Carry transform changes to the client so EGL applies
the same calibration to hardware cursors, and invalidate the full frame
whenever calibration changes.
Handle DEFAULT, NEW, and UNCHANGED IDDCX HDR10 metadata states and
publish valid mastering metadata through KVMFR. Preserve the metadata
across post-processing without reallocating resources for
metadata-only changes.
