Explain block/subblock runtime queries in workload-partitioning terms and remove redundant supported-forms wording from conversion ops docs. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add detailed mode parameter documentation (mode=0 vs mode=1) - Add 'Why get_buf/rls_buf is More Programmer-Friendly' section: - No manual priming/draining for ping/pong loops - No loop peeling for complex/nested loop dependencies - Simpler mental model (buffer ID + program order) - Add quick example comparison showing set_flag overhead vs get_buf simplicity - Update Example 2 and 3b with explicit mode=0 in code - Update comparison table with 'Loop peeling' row
- set_flag/wait_flag: 2 IDs per buffer (1 forward + 1 reverse pipe-pair) - get_buf/rls_buf: 1 ID per buffer (handles both directions automatically) - 8 per pipe-pair is HW limit, not a formula
- set_flag/wait_flag: 8 IDs per pipe-pair direction (HW limit) - get_buf/rls_buf: 1 buffer ID per shared resource (HW limit: 32 global), same ID used across all pipelines
- Event ID mgmt: each buffer occupies 1 ID per direction (removed misleading 4 IDs calc)
- Drain example: use concrete EVT_*_0/EVT_*_1 instead of {(N-1)%2} expressions
- 4 set_flag + 4 wait_flag (not 8) - 4 IDs = 2 pipe-pair directions × 2 ping/pong buffers
- set_flag/wait_flag: 1 MTE2 load, 8 Vector slices — must peel set/wait outside loop - get_buf/rls_buf: same pattern but acquire/release can stay inside or outside
- Acquire/release per slice inside loop - Iteration 0 blocks until MTE2 done, iterations 1-7 proceed immediately
Add the merged v0.3 PTO micro-instruction release spec document for A5, including ISA group references and updated synchronization notes. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Introduce a three-pass pipeline that lowers PTO tile ops to vector-level
implementations via TileLang DSL templates:
- ExpandTileOp: invokes TileLang Python DSL to instantiate template
functions and replaces tile ops with func.call. SpecKey covers all
operands; tile_buf operands are passed through without bridging.
- PTOInlineLibCall: extended to recognize tilelang instance functions via
the attribute set by the DSL frontend.
- FoldTileBufIntrinsics: resolves pto.tile_buf_addr / tile_valid_rows /
tile_valid_cols, including dynamic valid-shape via pto.bind_tile chain
tracing.
- MemrefToTileBuf: recovers tile_buf types from memref + bind_tile
metadata after PlanMemory/InsertSync.
- PTOViewToMemref: insert pto.bind_tile anchors for tile_buf function
args so MemrefToTileBuf can recover them.
Adds new PTO ops (tile_buf_addr/tile_valid_rows/tile_valid_cols),
ptoas pipeline wiring, design docs, and unit tests.
Implement missing predicate-op surfaces end-to-end in TileLang DSL v1, including semantic/lowering/test coverage and docs updates. Use PredicateDist enum for predicate load/store dist operands instead of raw strings. Closes hw-native-sys#124
