Shim
- Adaptive output-event wait: sleep to ~120 us before the predicted
completion (smoothed per wait site), spin near it, back off when late.
D4R_SHIM_OUTPUT_POLL_US restores a fixed interval.
- Defer the input-marker wait into the worker thread with VRAM interop
(D4R_SHIM_DEFER_MARKER, default on), taking the host setup off the
critical path.
MicroCUDA
- Experimental ZLUDA-free backend in wine_nvcuda_bridge, plus
tools/microcuda and scripts/build_microcuda.sh. Serves accuracy, fast
and native kernels; unregistered modules fall back to the reference
path. Unclassified writes invalidate prepared weights.
M kernels
- SWIN_PREP_IDENTITY_AT: key weight prep by allocation identity
(MicroCUDA); enc3 tube uses it with 8 slots. ZLUDA ignores it.
- dec2 (gfx1101): SWIN_PACKED_RESIDUAL, byte-identical, ~1.6% faster.
- Opt-in gfx12 hardware fp8 conversion (SWIN_FP8_HWCVT), unverified
on hardware.
Native K translators
- ctile: handle variants that re-materialize the parameter base (mvlo).
- rewrite_output: check live-in registers, not just outputs.
- build.sh: native input covers all 8 flag variants, output the 4 HDR
"max" variants; depth-tile skip stays mvhi-only.
Tools
- dump_runner and bench_dlss_kernel harness additions.
