[ExecuTorch][Vulkan] Tests for et_vk.q4gsw_requant#21101
Merged
Conversation
Pull Request resolved: #20946 **Correctness tests for the Vulkan `et_vk.q4gsw_requant` kernel** (stacked above the op diff). **Coverage:** the golden codes are computed with ATen (`round`/`clamp`, zero-scale -> code 8), mirroring `quant_nibble`, then packed into the expected W_4X8 int buffer with a small bit-packing reference (data-reshaping only, no hand-rolled math). The kernel output is compared int-for-int against that buffer, which locks the exact byte layout the forward reads. The latent is built as `code * scale` so `round()` is unambiguous (no `.5` tie-break divergence). Cases: - `test_tile_aligned` — single group, tile-aligned N/K. - `test_grouped` — multiple quantization groups along K. - `test_odd_n4` — `N % 8 != 0` (odd N4 -> padded stride + bias-zero OOB tile). - `test_zero_scale` — a zero scale must yield code 8, not a divide-by-zero. Also wires `q4gsw_requant_test` into `targets.bzl` + `CMakeLists.txt`. ghstack-source-id: 405059122 @exported-using-ghexport Differential Revision: [D111797526](https://our.internmc.facebook.com/intern/diff/D111797526/)

Pull Request resolved: #21005 Replace the hand-maintained explicit `WEBGPU_SRCS` op-handler list with `file(GLOB WEBGPU_OP_SRCS CONFIGURE_DEPENDS runtime/ops/*/*.cpp)` so adding a new op no longer requires editing this file (addresses review feedback). The five `runtime/*.cpp` sources and `runtime/ops/OperatorRegistry.cpp` (which sits directly under `ops/`, not a per-op subdir) stay explicit. `CONFIGURE_DEPENDS` re-globs at build time when op sources are added or removed. The glob resolves to exactly the 40 op handlers the explicit list enumerated (verified set-equal) — no op added or dropped, and static-init registration is order-independent under `--whole-archive`.
