Replaces the synchronous per-command execution model, and with it the
upstream render-target, pipeline-cache, tile-buffer, batched-draw and
memory-ownership commits (5a280ce, 7ed5a0b, 46c799d, 598caac, 40df528),
whose files are removed.
- Recorder: one open command buffer per device; dispatches, resident
draws, uploads, write-backs, labels, fills and copies record into it;
timeline-semaphore serials let drains wait without the GPU mutex;
completions run in order at reap.
- one worker thread per PM4 queue; labels and stores written by the GPU
into the host import; GPU-side DISPATCH_INDIRECT; the buffer-fill
kernel replaced by vkCmdFillBuffer; a dispatch cache validated by
write watch; filler packets tolerated; rejected submissions dumped.
- guest memory: page-state cache, 64 KiB write generations, host imports
with VK_EXT_external_memory_host, persistent mirrors of the executable
image, GPU copies of misaligned sub-ranges.
- textures: shader-written images stay resident with deferred
write-back (adjacent-generation rule for packed video planes), sampled
views of storage images, DCC key handling, addrlib swizzle equations,
bidirectional detiler.
- draws: MRT, more formats, dynamic viewport/scissor, cached pipelines,
resident 64 KiB targets, draws recorded into the recorder.
- ShaderResources: two-stage build, descriptor and sampler caches, a
content-keyed resource cache; presentation from the resident image.
- a label deferred behind a completion is no longer re-stored by the
CPU at reap time unless a write-back overwrote it.
