This pull request includes several changes to improve the handling of decoding and memory prefetching in the GPU intrinsics and matmul dequantization logic. The key changes involve adding support for offset handling in decoding functions, updating the pass context for TVM transformations, and enhancing the scheduling logic for shared memory prefetching.
Decoding Enhancements:
decode_i4_to_f16_scale_offset
,decode_i4s_to_f16_scale_offset
, anddecode_i4u_to_f16_scale_offset
to handle offset during decoding (bitblas/gpu/intrin/lop3.py
).get_fast_decode_intrin
to append_offset
to function names whenstorage_scope
is "warp" and scaling is enabled (bitblas/gpu/intrin/lop3.py
).TVM Transformation Context:
tvm_callback_cuda_postproc
function to include"tir.disable_cse_tir": True
in the TVM pass context configuration (bitblas/base/utils.py
).Scheduling and Prefetching:
sch_shared_memory_prefetch_with_config
(bitblas/gpu/matmul_mma_dequantize.py
).get_param_indices
andfetch_to_shared
functions to support reduction across threads (bitblas/gpu/matmul_mma_dequantize.py
). [1] [2]Intrinsic Definitions:
intrin_definitions
to support various configurations (bitblas/gpu/intrin/lop3.py
).These changes collectively enhance the functionality and performance of the GPU intrinsics and matmul dequantization processes.
