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.
Replace the rotating D3D12 copy queues with two framebuffer-bound
recording slots on one physical COPY queue. Keep allocator, command
list, query range, callback state, and fence target independent per
slot.
Submit source waits, execution, and signaling on the shared timeline.
Track framebuffer ownership through completion and serialize LGMP
publication around the last successfully published frame.
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.
