Add default-off PreferAccuracy with conservative native variants for every RDNA3/RDNA4 target and a separate JIT cache. Preserve fast defaults and reject mixed accuracy sets. Add a pinned Debian build environment, rebuild all release components against GLIBC 2.41, and include toolchain provenance and release notes for the accuracy changes and the preceding artifact/synchronization fixes. Refs #6; CPU-overhead confirmation for #7 remains pending.

# Builds the native replacements for DLSS kernels into one directory that ZLUDA serves them from
|
|
# (D4R_ZLUDA_NATIVE_DIR, or NativeKernelDirFast in d4r.ini). See docs/native-kernels.md.
|
|
#
|
|
# usage: kernels/build.sh [all|k|m|tex] [OUT_DIR] (default: all, kernels/out/native)
|
|
#
|
|
# D4R_ROCM_DIR ROCm installation with clang and the HIP device libraries (default /opt/rocm)
|
|
# D4R_GPU_ARCH target GPU (default gfx1101): an RDNA3 (gfx110x) or RDNA4 (gfx120x) target; the kernels
|
|
# need wave32 WMMA, and kernels/common/wmma_layout.h picks the register layout per target
|
|
# D4R_NATIVE_FP8 1 (RDNA4 only): the variant for ZLUDA's native FP8 WMMA (d4r.ini [Kernels] NativeFp8):
|
|
# M's layers on FP8 WMMA with NVIDIA's e4m3 activations, texture tails matching ZLUDA's
|
|
# D4R_ZLUDA_WMMA_FP8_NATIVE lowering. K is the same in both variants.
|
|
# D4R_PREFER_ACCURACY 1: preserve FP8 quantization, per-MMA f16 rounding and denormal handling;
|
|
# build a separate set (default output: kernels/out/native/accuracy).
|
|
# Texture kernels (tex) are NVIDIA's PTX with parts replaced, so they additionally need:
|
|
# D4R_DLSS_DLL nvngx_dlss.dll 310.7 (its PTX is extracted into kernels/extracted/, never committed)
|
|
# D4R_ZLUDA_EMIT ZLUDA's d4r_emit (patches/zluda applied; `cargo build --release -p ptx --example d4r_emit`),
|
|
# which compiles PTX offline for D4R_GPU_ARCH (no GPU of that kind needed)
|
|
# D4R_DLSS_PTX_DIR optional pre-extracted PTX directory for parallel per-target builds
