deepseek-ai#347

Merging this in before the return of SBO feature (since it might further conflict)

For example, some of the features of this PR are:

  1. BF16 GEMM accumulation when the output is the same dtype (when problem size is large, the improvement can be 10-15%)
  2. Mega MoE changes
  3. Paged MQA changes

RayWang96 and others added 2 commits June 1, 2026 17:11
* Optimize FP8/FP4 Mega MoE dispatch, scheduling, and shared memory layout
* Add BF16 accumulation/output support updates for GEMM paths
* Improve paged MQA scheduler and attention coverage
* Minor fixes and test updates
