Add an experimental FSR Ray Regeneration backend for D3D12 RR requests: - Convert depth, motion, normals and albedos into AMD denoiser inputs. - Split and recompose diffuse/specular signals, then run Super Sampling. - Add stability/detail controls, demodulation guards and halo limiting. - Handle AMD provider discovery under NVIDIA GPU spoofing. - Add runtime probes, synthetic reference scenes and per-dispatch profiling. Add exact gfx11 DLSS-RR inference using f16 cooperative matrices: - Reproduce FP8 conversions, accumulation and camera reprojection arithmetic. - Widen model weights and avoid requiring VK_EXT_shader_float8. - Extend model building, replay tools and descriptor metadata. Expand motion preprocessing and experimental AW2 native-motion support: - Add tiled LDS dilation, padded allocation handling and thin-only sky fill. - Order dilation with input waits and NGX on the selected stream. - Add jitter-aligned native composition, hybrid routing and wire history repair. - Add prepared masks, sparse repair and independent motion/repair controls. Add optional fused R11G11B10 input/output conversion, sampled stage timings and profile summarization. Extend configuration, packaging, documentation, FidelityFX headers and CPU/GPU regression coverage.

"""Append the RDNA3 (RR_GFX11) widened copy of a native stage's weight file and print its f16 element offset (W_WIDE).
|

|
|
usage: widen_weights.py WEIGHTS.bin [OUT.bin] (default: in place)
|
|
|
|
Element W_WIDE + j of the file's f16 view is byte j of the original image as ZLUDA widens an FP8 operand on gfx11
|
|
(rr_gfx11.glsl): the magnitude at bits 7..14, the sign at bit 15, the NaN code with bit 14 set too, i.e. the binary16
|
|
of value * 2^-8. Bytes that are not FP8 (tables, binary16 data) are widened as well and never read. W_WIDE is the
|
|
original size rounded up to 512 bytes, halved.
