* Add TMA copy for packed global FP4 to unpacked SMEM.
Wire IsValidTMACopyDtypePair and ALIGN16B tensor map descriptors for
float4_e2m1fn global to float4_e2m1_unpacked shared transfers, and
extend language tests for TMA and SIMT copy restrictions.
* Extend tcgen05 MMA metadata for FP4 f8f6f4 and dtype helpers.
* Refactor tcgen05_gemm_blockscaled API and lowering.
* Use separate A/B dtypes in GEMM tileop emitters across backends.
* Add maint/gemm correctness evaluation scripts and update gemm_sm100 examples.
* Fix profiler assert_allclose to compare outputs only.
* lint
* canonicalize data types
* add dpgm fp8-fp4 kernel
* resolve comments
* Refine FP4 unpacked SMEM dtype handling
Treat float4_e2m1_unpacked as a SMEM/TMA-only storage tag instead of a general vector/register dtype. Remove vectorized Python aliases and keep codegen uses constrained to shared-memory storage/reference paths that lower to uint8_t.
Allow packed FP4 global tensors to TMA-load into unpacked shared memory with the ALIGN16B TensorMap format, while keeping unpacked storage out of TMA store paths. Use payload-bit accounting for global strides and mbarrier transactions.
Add focused dtype and TMA descriptor tests, and validate the real tcgen05 fp4-unpacked GEMM paths.
* Restrict FP4 unpack TMA to loads
* Hide vectorized unpacked FP4 language aliases
* Update TVM for unpacked FP4 symbol exports
* Rebind TVM submodule to merged unpacked FP4 export fix
* Enable cache for persistent tcgen5 GEMM example
