When vulkan memory model is used, two keywords, "Coherent" and "Volatile", are not allowed. There are many differences regarding atomic and texture but this PR has changes limited to support `globallycoherent` keyword. When variables with `globallycoherent` is used with `OpLoad`, it will use additional options, `MakePointerAvailable|NonPrivatePointer`, that will provide the same effect. For `OpStore`, it will use `MakePointerVisible|NonPrivatePointer`. 2025-05-15T03:47:43+00:00 Jay Kwak 82421531+jkwak-work@users.noreply.github.com 2025-05-15T03:47:43+00:00 urn:sha1:2580bb02f7a079ab1c0106b5960a21ed1627bca0 This commit adds three new functions for CoopMat as described in the proposal document, Cooperative matrix 2 proposal spec#12 The new functions are: CoopMat<T,S,M,N,R>::Transpose CoopMat<T,S,M,N,R>::ReduceRow CoopMat<T,S,M,N,R>::ReduceColumn CoopMat<T,S,M,N,R>::ReduceRowAndColumn CoopMat<T,S,M,N,R>::Reduce2x2 2025-04-25T17:39:45+00:00 Gangzheng Tong tonggangzheng@gmail.com 2025-04-25T17:39:45+00:00 urn:sha1:d84aeeffdba388aec7a781c35973bf404d37fe80 * Update spirv-tools to for SDK v2025.2 Fixes: #6850 * bump spirv version to 1.4 for op linkage * skip-spirv-validation for coop mat * add skip-spirv-validation option to slang session desc * use SPV_ENV_UNIVERSAL_1_6 for spirv-tool env target Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> --------- Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> 2025-04-15T21:57:45+00:00 Darren Wihandi 65404740+fairywreath@users.noreply.github.com 2025-04-15T21:57:45+00:00 urn:sha1:d0b6a0b1ab49b5958015f31364c5ad73d9cd03eb * initial wip for spirv * working tiled example * clean up store and load * minor fixes * fix loadAny name * add initial tests, including broken/unimplemented intrinsics * fix subscript * run tests at 16x16, remove not supported arithmetic tests * minor fixups on implementation * rename CoopMatMatrixUse * Update tests to pass validation layers locally * Add mat-mul-add test and minor fixes * Add more tests * Remove dead code * Add coopMatLoad function and tests, enforce constexpr for matrix layout * Use getVectorOrCoopMatrixElementType in place of getVectorElementType
