* * [CK_TILE] Add sequence padding and variable length support in fmha (and v3) - Group Mode Padding: Introduces the `-s_qpad` argument to support physically padded layouts. Kernels now use padded start pointers (`seqstart_padded_*_ptr`) for memory addressing. - Batch Mode Variable Length: Adds `-q_eff_lens` and `-kv_eff_lens` arguments for efficient processing of variable-length sequences by passing cumulative effective lengths (`cu_seqlen_*_ptr`) to the kernel. - FMHA examples: Support padding and variable length both in group and batch mode. Dispatcher is updated as well (dispatch to kPadSeqLenK enabled pipeline). - New padding test cases: Add padding test cases to `smoke_test_fwd.sh` and `test_fmha_fwd.inc`, and add benchmarks to `benchmark_fwd.sh` and `benchmark_fwd_v3.sh` as well. These test cases and benchmarks that specifically validate/benchmark the new padding and variable-length functionalities in both group and batch modes. * [CK_TILE] Fix build error in fmha unit tests * [CK_TILE] add mqa, gqa to sequence padding unit tests * [CI_TILE] Reduce the number of padding seqlen unit tests in FMHA to avoid timeouts in CI * [CK_TILE] remove unnecessary MageKArgs overload in FmhaFwdV3Kernel and FmhaFwdKernel
