Summary by CodeRabbit

Refactor
- Softmax max-tracking consolidated across attention kernels: current and previous per-row maxima are merged to improve numerical stability and consistency during attention normalization.
Tests
- Transformation tests updated to validate the revised max-tracking behavior.
Documentation
- Examples and README updated to describe the new per-row max consolidation step.

Walkthrough

Adds an explicit elementwise merge of current and previous per-row/block maxima across many attention kernels: after each T.reduce_max, code now performs scores_max[i] = max(scores_max[i], scores_max_prev[i]) before subsequent scaling/exponentiation.

Changes

Cohort / File(s)	Change Summary
Attention Sink Examples `examples/attention_sink/example_gqa_sink_bwd_bhsd.py`, `examples/attention_sink/example_gqa_sink_fwd_bhsd_wgmma_pipelined.py`, `examples/attention_sink/example_mha_sink_bwd_bhsd.py`, `examples/attention_sink/example_mha_sink_fwd_bhsd.py`, `examples/attention_sink/example_mha_sink_fwd_bhsd_wgmma_pipelined.py`	Inserted a parallel per-row/block max: `scores_max[i] = max(scores_max[i], scores_max_prev[i])` immediately after `reduce_max` inside Softmax paths.
Block-sparse Attention & Benchmark `examples/blocksparse_attention/example_tilelang_sparse_gqa_decode_paged.py`, `examples/blocksparse_attention/example_tilelang_sparse_gqa_decode_varlen_indice.py`, `examples/blocksparse_attention/example_tilelang_sparse_gqa_decode_varlen_mask.py`, `benchmark/blocksparse_attention/benchmark_tilelang_block_sparse_fmha.py`	Replaced conditional-max updates or added explicit `T.max(scores_max[i], scores_max_prev[i])` merges in `block_H` loops right after per-block `reduce_max`.
Deepseek MLA Examples `examples/deepseek_mla/...`, `examples/deepseek_mla/amd/benchmark_mla_decode_amd_tilelang.py`	Added parallel per-`block_H` max-merge steps after `reduce_max` in both `flash_attn` and `flash_attn_split` code paths (multiple files under this cohort).
Flash Attention — Forward `examples/flash_attention/example_gqa_fwd_bshd.py`, `examples/flash_attention/example_gqa_fwd_bshd_wgmma_pipelined.py`, `examples/flash_attention/example_gqa_fwd_varlen.py`, `examples/flash_attention/example_mha_fwd_bhsd.py`, `examples/flash_attention/example_mha_fwd_bshd_wgmma_pipelined.py`, `examples/flash_attention/example_mha_fwd_varlen.py`	Added parallel per-row max merge `scores_max[i] = max(scores_max[i], scores_max_prev[i])` after `reduce_max`; some pipelined variants also adjusted pipeline grouping indices.
Flash Attention — Backward / TMA Variants `examples/flash_attention/example_gqa_bwd.py`, `examples/flash_attention/example_gqa_bwd_tma_reduce.py`, `examples/flash_attention/example_gqa_bwd_tma_reduce_varlen.py`, `examples/flash_attention/example_gqa_bwd_wgmma_pipelined.py`, `examples/flash_attention/example_mha_bwd_bhsd.py`, `examples/flash_attention/example_mha_bwd_bshd.py`, `examples/flash_attention/example_mha_bwd_bshd_wgmma_pipelined.py`	Inserted per-`block_M` parallel max merges with `scores_max_prev` immediately following `reduce_max` in forward kernels used by backward paths.
Flash Decoding / Inference `examples/flash_decoding/example_gqa_decode.py`, `examples/flash_decoding/example_mha_inference.py`	After per-block `reduce_max`, added parallel `scores_max[i] = max(scores_max[i], scores_max_prev[i])` merges in both `flash_attn` and `flash_attn_split` flows.
AMD & Misc Examples `examples/amd/example_amd_flash_attn_fwd.py`, `examples/amd/example_amd_flash_attn_bwd.py`, `examples/minference/example_vertical_slash_sparse_attn.py`, `examples/seer_attention/block_sparse_attn_tilelang.py`	Introduced elementwise max merges with previous maxima after `reduce_max` in forward/backward and sparse-attn compute paths.
Deepseek V32 / Sparse MLA Pipelined `examples/deepseek_v32/...`, `examples/deepseek_v32/sparse_mla_fwd_pipelined.py`	Added per-block H parallel max-updates m_i[h] = max(m_i[h], m_i_prev[h]) after reductions in multiple locations.
Testing / Docs / Minor Edits `testing/python/transform/test_tilelang_transform_config_index_bitwidth.py`, `examples/flash_attention/README.md`, `examples/flash_attention/example_gqa_fwd_varlen.py`	Added test/code examples to exercise the merge; README updated to mention the merge; one file had a whitespace-only edit.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

Files/areas needing extra attention:
- Pipelined / wgmma variants where pipeline grouping indices changed — verify scheduling and indices.
- Split-kernel and paged variants — ensure scores_max_prev is initialized, in-scope, and has correct lifetime.
- Varlen/windowed and -inf sentinel handling — verify numerical stability when merging previous maxima.

Possibly related PRs

[Example] Update GQA varlen fwd #1173 — similar change adding post-reduction per-row max merges in Softmax paths.
[GQA] Use TMA in GQA bwd kernel to boost performance #1176 — related edits to softmax/max initialization and handling in attention kernels.
[EXAMPLE] In the flash attention example keep the max of all blocks seen in scores_max numerical stability #1148 — implements the same post-reduction scores_max = max(scores_max, scores_max_prev) pattern.
