2e49b6b2f7 Padding support for wave transfer (#3537)
* Add padding support with transpose

Also move check before writing storing is_src_valid during reading

* Add/modify instances to use wave transfer for gemm universal

Condition is changed so now the vectorsize of vmem reading and lds
writing must be equal to 8 in order to use the wave transfer

* Fix clang format

* Modify example

* Fix bwd data

* Add restriction for wave transfer with padding and transpose

Add test case which shows this limitation

* Fix validity checks 8 bit types

* Add validity check gemm_bias_add_reduce

* Add validity check grouped gemm tile loop

* Fix validity checks new flavours

* Minor fixes

* Fix clang format

440358c168 Wave Tile Transfer supporting global load with transpose (#3027)
* Initial implementation:

 - add new thread group transfer supporting transpose instruction
 - refactor AB transfer to switch between thread and wave tiles methods

* Add some comments and remove explicit wave and lane calculations

* Remove compiler option for performance

* fp16 example: use tuned instance

* Missing cleanup

* Integrate wave transfer in existing gemm and batched gemm instances

* Add fast instances

* extend implementation for 8 bit datatypes

packed types not supported

* Address review comments

* Optimize pipeline v1 and re-introduce compiler option

* Disable wave tile approach for b scale gemm

* Fix for clang20

* Avoid code duplication of amd_global_load_transpose_to_vgpr function

52b4860a30 WMMA GEMM universal pipeline v1, mixed precision and paddings, examples (#2230)
* Fixed cmake errors related to  gemm_bilinear. Previously, if the above flags are set, cmake build fails: GPU_TARGETS="gfx1100;gfx1201" -D DTYPES="fp16;bf16;fp8"

* Fixed cmake build errors related to test_fp8

* Updates to support mixed precision

* Adding support for RRR, F8xF16xF16 gemm_universal_wmma - wip

* Added support for F8xF16xF16 to gemm_wmma_universal

* Added support for F16xF8xF16 to gemm_wmma_universal

* Added support for BF16xI4xBF16 to gemm_wmma_universal

* Added support for F16xI4xF16 to gemm_wmma_universal

* Fixed IsSupportedArgument to check ComputeTypeA, ComputeTypeB instead of ADataType, BDataType

* Added missing test class for FP16_KM_NK

* Pre-commit hooks fixes

* Added padding instances for f16xf16xf16

* Fixed cmake errors related to  gemm_bilinear. Previously, if the above flags are set, cmake build fails: GPU_TARGETS="gfx1100;gfx1201" -D DTYPES="fp16;bf16;fp8"

* Fixed cmake build errors related to test_fp8

* Ammending changes for adding support for padding instances for f16xf16xf16

* Fixes for padding instances for f16xf16xf16

* Added padding instances for bf16xbf16, f8xf8

* Added packed instances for bf16xi4xbf16

* Added padding instances for f8xf16xf16

* Added padding instances for f16xf8xf16, f16xi4xf16

* Fixed typos for bf16xbf16xbf16 padding instances

* Fixed typos for padded instances

* Added tests for fp16, KM_KN and KM_NK

* Padding not supported for when BDataType is pk_i4_t. Added fix for correct check and removed padding instances.

* Fixed typos

* Updated the set of tests for FP16

* Updated the set of tests for FP16

* Fix typo

* Moved f16xi4 test under the correct data layout group

* example for gemm_universal_bf16

* Adding examples for gemm_wmma instances

* Added the  missing parameters

* Fixed review comments and added executable to cmakeLists

* Fixing clang format

* Fixing build erros

* Fixed compilation failure.

* Modified some code as per gemm_universal_examples

* Fixed the gemm specialization error

* Fixed the build errors.

* Fix strides of a/b_thread_desc

The descriptors are larger than needed (even though the compiler don't alloc registers for unused values).

* Load in M/NRepeat dims with thread copy's slice instead of a loop

* Clone BlockwiseGemmXdlops_pipeline_v1 for WMMA implementation

* Implement Intrawave and Interwave variants of pipeline v1

* Add instances for Interwave and Intrawave v1

* Add instances with ABlockLdsExtraM and BBlockLdsExtraN = 0

* Remove instances that are too slow (mostly because of register spilling)

* Add a workaround for fp8/bf8->f32 packed conversion issue

* Add instances for Interwave and Intrawave v1

* Enable profiling of mixed precision with f8 and int4 on WMMA

* Fix segfault in profiler when B is pk_i4_t

b_device_buf's size in bytes is larger than b_k_n_permute so b_device_buf.ToDevice reads out-of-bounds.

* Remove instances that are too slow (mostly because of register spilling)

* Add missing add_device_gemm_wmma_universal_f8_f8_bf16 declarations

* Add test case for bf16_i4

* Add missing Regular tests

* Add test_gemm_universal_xdl/wmma_fp16 to REGRESSION_TESTS

They take more than 30 seconds

* Fix a bug that fp16_i4 validation passes only with PermuteB

A permutation required by conversion from pk_i4_t to half_t does not
depend on PermuteB, they can be used independently.

* Use PermuteB with f16_i4 in most instances (as xdl)

Some instances use PermuteB = false for checking correctness.
See also the previous commit.

* Fix cache flushing for pk_i4

* Add mixed precision examples

* Disable all tests and instances with f8 on gfx11

Even though f8_f16 and f16_f8 don't require f8 WMMA instructions,
gfx11 still lacks hardware instructions for fast f8->f32 conversion.

* Add FP16 KM_NK and KM_KN test suites for XDL

These tests were added to common .inc for better testing of WMMA instances

* Fix int8 DTYPES check for gemm_bilinear
