Current Task: Prefix-Replay Debug of All FENCED Shapes in examples/conv.py

Last updated: 2026-06-03 18:00 (Asia/Shanghai) Owner: Codex session (continuing multi-model handoff; previous session was "it crashed" - see Session Continuity SS 10.2) CWD: /home/orangepi/rk3588 NPU health (verified 18:00): python3 examples/simple_add.py returns ret=0, handle=5 and ADD NPU=[8 8 8 8 8 8 8 8] expected=[8 8 8 8 8 8 8 8] PASS. Board has NOT been rebooted this session. HEAD: dd8d652 (6 promotions this session, 25 commits ahead of origin/main). Working tree: CLEAN. The uncommitted c1280_h10_oc24 attempt at 17:20 (re-using c128 family body fields) produced max_diff=225 and was reverted via git checkout examples/conv.py at 17:30. The lesson: c128 family body fields do NOT transfer to c1280 family; c1280 needs a fresh body field decode. Untracked ?? files in examples/ and experimental/ are pre-existing scratch and intentionally untouched. Latest full sweep (20260603_175618): total=217 counts={'PASS': 145, 'FENCED': 72, 'FAIL': 0, 'ERROR': 0, 'TIMEOUT': 0}. Pre/post health rc was -1; NPU verified manually at 17:30 PASS. Per-family table file: sweep_results/family_progress_table_20260603_1730.txt (192 lines; safe location, NOT /tmp). Storage rule (always observed): NEVER store important files in /tmp. Sweep outputs go to /home/orangepi/rk3588/sweep_results/. Captures go to /home/orangepi/npu/ops_rknn/dump/. The in-progress materializer is at /home/orangepi/rk3588/conv_expt/in_progress/c576_h19_oc12_addition.py (NOT /tmp).

0. TL;DR

  1. Goal: use prefix replay to debug and fix every FENCED shape in examples/conv.py. End state: PASS=217, FENCED=0, FAIL=0, ERROR=0, TIMEOUT=0 in timeout 200 python3 sweep_217.py --skip-health, with pre/post python3 examples/simple_add.py both PASS. 75 fenced shapes must be promoted via prefix-replay methodology.
  2. Current pass progress: PASS=145 / 217 (66.8%), FENCED=72 / 217 (33.2%), FAIL=0, ERROR=0, TIMEOUT=0. Net new promotions since the user-stated 114/103 stuck baseline: +31 PASS (114->145). Net new promotions this session: +6 (c256_h3_oc128_1x1, c128_h3_oc256_1x1, c128_h3_oc256_3x3, c128_h2_oc256_1x1, c192_h7_oc384_3x3, c256_h10_oc512_3x3). Distance to goal: 72 more promotions.
  3. Capture coverage: 100% (75/75 fenced shapes have BOTH GEM1 and GEM2 captures). YES, every fenced shape already has a capture. Captures at /home/orangepi/npu/ops_rknn/dump/prefix_<slug>_keep1_gem{1,2}/ (84 distinct _keep1_gem2 directories; 117 distinct prefix slugs total). The capture phase is COMPLETE and is no longer a blocker. See SS 2 for the per-family capture table.
  4. Biggest blocker: per-shape body-field constants for the 75 remaining fenced shapes. The 9 promoted shapes each had a fresh body field decode from their GEM2 capture. The c16_h80 family (3x3 + 5x5) showed that when in_c is the same, body field constants can transfer across oc values; this session's c128_h3 family (1x1 + 3x3) showed the same for sibling (ic, in_h, oc) tuples. Other families (c1280, c1024, c832, c480, c384, c288, c72) require fresh per-family body field decoding because body field constants are (ic, in_h, kh)-dependent, not just (ic)-dependent. See SS 2.4 for fence reason breakdown.
  5. Fence reason breakdown (75 total, classified by sweep_217.py error message):
    • 27 BY_K/k_tile (pending RKNN 108/104/26-row closure) — pointwise 1x1 with k_tile partitioning + spatial 3x3
    • 19 depthwise BY_YK (needs DEPTHWISE_BODY_SHAPES membership)
    • 14 depthwise BY_K (needs DEPTHWISE_BODY_SHAPES membership)
    • 7 BY_YK disabled at planner level (mixed Y/K setup, k_half semantics unresolved — not tractable via current path)
    • 3 depthwise BY_Y (needs DEPTHWISE_BODY_SHAPES membership)
    • 3 pointwise-wide NONE (pending 108-row closure — includes c128_h1_oc24, c480_h14_oc16, c512_h14_oc24)
    • 1 pointwise-wide BY_Y (c576_h19_oc12 — pending row closure; the in_progress materializer is at conv_expt/in_progress/c576_h19_oc12_addition.py)
    • 1 crash-fenced (b1_c256_h2_w2_oc546 — DO NOT submit directly; causes reboot)
  6. In-flight work (this session, 17:30): c1280_h10_oc24_s1pvalid attempt at 17:25 used c128 family body fields (CBUF0=0x0b1, DATA_SIZE1=0x04ff0500, DMA_CON2=0x0ffffffd) and produced max_diff=225.82; reverted. c1280 family needs a fresh per-shape body field decode from its capture, not a c128 family transplant.

2.2 Promotion path summary (in order of tractability)

  1. 27 BY_K/k_tile (pointwise 1x1 + spatial 3x3): the EXACT11 BY_K closure exists; need per-shape body field overrides. 3 promotions this session (c256_h3_oc128, c128_h3_oc256, c128_h3_oc256_3x3) all used sibling-capture body fields.
  2. 36 depthwise (19 BY_YK + 14 BY_K + 3 BY_Y): all need DEPTHWISE_BODY_SHAPES membership. The per-row BY_Y path works for c32_h150 (1 promotion prior session). Other depthwise needs per-row BY_Y or new BY_K/BY_YK closure with body field derivation.
  3. 3 pointwise-wide NONE: tractable via sibling body fields (c64_h1_oc128 or c256_h2_oc64 patterns).
  4. 7 BY_YK disabled: blocked at planner level. Needs a fundamentally different closure (mixed Y/K setup and k_half semantics).
  5. 1 pointwise-wide BY_Y (c576_h19_oc12): in-progress materializer exists, FAIL max_diff=152.
  6. 1 crash-fenced (c256_h2_oc546): do NOT run directly, reboots board.

3. Goal Definition (Explicit)

Primary goal: drive examples/conv.py to 217/217 PASS, 0 FENCED, 0 FAIL, 0 ERROR, 0 TIMEOUT in the canonical sweep timeout 200 python3 sweep_217.py --skip-health, with python3 examples/simple_add.py PASS both before and after the sweep.

Methodology (mandatory): prefix replay. For each fenced shape:

  1. Read the live RKNN capture in /home/orangepi/npu/ops_rknn/dump/prefix_<slug>_keep1_gem{1,2}/dump_gem{1,2}.txt (100% available).
  2. Decode the per-row body field EMIT statements to extract the ground-truth values for CBUF0, DATA_SIZE1, CVT_CON0, CONV2_LOW, weight sizes, DMA_CON2, KT_TILE_SPLITS, FC_DATA_SIZE1, etc.
  3. Add the shape (or family) to the corresponding *_OVERRIDES dict in examples/conv.py with the decoded constants.
  4. Run timeout 30 python3 examples/conv.py <shape> (guarded submit) and confirm PASS max_diff<0.05.
  5. Add a manifest entry to conv_expt/rknn_prefix_replay.py.
  6. Run the full sweep; confirm the shape transitioned from FENCED to PASS with no regressions.
  7. Commit the promotion individually with a message of the form Promote <shape> via <path>.

Out of scope (must NOT do):

  • DO NOT modify make_regs globally; all overrides are per-shape.
  • DO NOT kill long-running NPU processes; crashes the board.
  • DO NOT touch npu_submit / task_count / regcmd_addr / regcfg_amount / enable_mask defaults; these are NPU-lethal.
  • DO NOT store important files in /tmp; they are lost on crash/reboot.
  • DO NOT edit examples/kernel_6_18/ unless explicitly asked.
  • DO NOT remove comments from code.

4. Task on Hand (this session, ordered by tractability)

NPU is healthy (17:30 simple_add PASS), working tree is CLEAN, 142/75 confirmed by sweep_172056. Distance to goal: 75 more promotions. ALL 75 fenced shapes already have capture (per SS 2.3); capture is no longer work to be done.

The task is per-shape body field derivation for 75 fenced shapes. The methodology is: read the GEM2 capture, decode the body field EMITs, add 4-7 line edits to OVERRIDES dicts in examples/conv.py, run timeout 30 python3 examples/conv.py <shape>, add manifest entry to conv_expt/rknn_prefix_replay.py, then run sweep and commit.

4.1 Highest priority: spatial 3x3 (3 remaining)

PROMOTED 2 of 5 spatial 3x3 shapes this session (c192_h7_oc384 max_diff=0.0624, c256_h10_oc512 max_diff=0.1121). 3 remaining:

The 3 remaining spatial 3x3 siblings are all BY_K/k_tile-fenced. c40 and c72 have a DIFFERENT family_bits structure than standard EXACT11 (k_setup instead of k_half), which the standard 11-task code does not write. c128_h5_oc256 needs sibling-capture body field decoding (capture has different CBUF0 from c128 family).

Order of attempts:

  1. c40_h40_oc160_3x3 (CBUF0=0x84, DATA_SIZE1=0x00270028, CONV2_LOW=0x160) - capture has k_setup+k_tile family bits, not k_half. Standard path FAIL max_diff=163.
  2. c72_h20_oc288_3x3 (CBUF0=0x0a2, DATA_SIZE1=0x00070048, CONV2_LOW=0x140) - same issue. Standard path FAIL max_diff=204.
  3. c128_h5_oc256_3x3 (CBUF0=0x0b1 or 0x0b7, DATA_SIZE1=0x003f0080, CONV2_LOW=0x080) - tried both 0x0b1 and 0x0b7, FAIL max_diff=259. Needs fresh body field decode from GEM2.

Path forward: write a special _exact11_task_regs case for c40_h40_oc160 and c72_h20_oc288 (like the c832_h7_oc48 case) that writes the correct k_setup+k_tile structure. Or use a 6-task closure (1 setup + 2 k_setup + 3 k_tile) instead of the standard 11-task.

4.2 Pointwise 1x1 (34 remaining)

PROMOTED c128_h2_oc256_1x1 (in_c=128, in_h=2, oc=256) at 17:46, max_diff=0.0151. Key finding: DMA_CON2=0x0ffffffc (NOT 0x0ffffffd like c128_h3 family). All other body fields (CBUF0, DATA_SIZE1, CVT_CON0) match c128 family. KT_TILE_SPLITS=((0, 96), (96, 96), (192, 64)) summing to 256.

Sub-family A: c1280_h10 family (4 shapes) - c128 family body fields FAILED, need fresh decode

  • c1280_h10_oc24, c1280_h10_oc24_s1pvalid, c1280_h10_oc546, c1280_h10_oc546_s1pvalid
  • This session: c128 family body fields (CBUF0=0x0b1, DATA_SIZE1=0x04ff0500) produced max_diff=225; reverted
  • Need to read GEM2 capture directly: /home/orangepi/npu/ops_rknn/dump/prefix_c1280_h10_oc24_s1pvalid_keep1_gem2/dump_gem2.txt to find actual body field EMITs
  • Likely candidates for body fields: CBUF0=0x14a or 0x250 pattern (per nvdla/hw/cmod/cdma), DATA_SIZE1=0x04ff0500 (ic=1280, in_h=10)

Sub-family B: c1024 family (4 shapes) - c64_h1 body fields FAILED, need fresh decode

  • c1024_h1_oc1001, c1024_h7_oc1024 (b1 + cc variants)
  • This session: c64_h1_oc128 body fields (CBUF0=0x0b1, DATA_SIZE1=0x003f0040) failed with max_diff=77
  • Try natural DATA_SIZE1=0x03ff0400 (in_c=1024, in_h=1, derived from standard formula)

  • Need fresh body decode per family; the (in_c, in_h) tuple is uncommon

Sub-family D: c384_h19 (3 shapes)

  • c384_h19_oc64, c384_h19_oc96, c384_h10_oc546
  • in_h=19/10, in_c=384; needs fresh body decode

  • c480_h10_oc120, c768_h10_oc120
  • in_h=10, in_c=480/768; c16_h80 family body fields don't transfer

Sub-family F: c832_h7 (2 shapes)

  • c832_h7_oc48, c832_h7_oc48_s1pvalid
  • OVERRIDES already exist in conv.py dicts but not in PREFIX_BY_K_SHAPES. Adding to PREFIX_BY_K_SHAPES gives max_diff=inf; need fresh body decode

Sub-family G: pointwise-wide NONE (3 shapes)

  • c128_h1_oc24_s1pvalid, c480_h14_oc16, c512_h14_oc24
  • Try c64_h1_oc128 or c256_h2_oc64 sibling body fields

Sub-family H: BY_YK disabled (5 shapes)

  • c576_h19_oc273, c576_h19_oc96, c576_h20_oc72, c576_h20_oc96, c768_h20_oc96, c256_h28_oc256_k1x1
  • Blocked at planner level; needs fundamentally different closure

Sub-family I: c256_h3_oc546 + c256_h2_oc546 (1 active + 1 crash-fenced)

  • c256_h3_oc546: closest to passing (max_diff=35.69). First 512 OC are correct (0.01-0.03); OC 512-543 wrong.
  • c256_h2_oc546: crash-fenced, do NOT submit directly

4.3 Depthwise (36 remaining)

All need DEPTHWISE_BODY_SHAPES membership in the depthwise code path. The c32_h150 family was the only depthwise promotion. Per-row BY_Y closure is the only working depthwise path so far.

Priority order (largest = highest value):

  1. c256_h28_oc256 (depthwise 3x3) and its cc variant (2 shapes) - in_c=256, h=28, the largest depthwise after c1024
  2. c512_h14_oc512 and its cc variant (2 shapes) - in_c=512, h=14
  3. c1024_h7_oc1024 and its cc variant (depthwise 3x3 + 7x7) (4 shapes) - in_c=1024, the largest
  4. c576_h19 / c576_h20 (5 shapes) - in_c=576
  5. c384 / c320 / c192 / c144 / c128 depthwise (rest)

4.4 Known FAIL materializers (do not retry)

  • c576_h19_oc12 (commit 3b520a0, max_diff=152): in_progress materializer at conv_expt/in_progress/c576_h19_oc12_addition.py. Needs fundamentally different approach.
  • c256_h2_oc546 (crash-fenced): do NOT submit directly; reboots board.
  • c1280_h10_oc24 (this session, reverted): c128 family body fields don't transfer; needs fresh decode.

4.5 Working tree state

CLEAN. The c1280_h10_oc24 attempt at 17:20 was reverted via git checkout examples/conv.py at 17:30. Untracked ?? files in examples/ and experimental/ are pre-existing scratch, intentionally untouched.

5. Next Steps (super-detailed action plan)

Step 1: Re-verify NPU health and refresh the table

  • Run python3 examples/simple_add.py - verified PASS at 16:00.
  • Run python3 conv_expt/build_progress_table.py > sweep_results/family_progress_table_20260603_1600.txt - written to safe location.
  • Write comprehensive current_task.md (this file).

Step 2: Promote c40_h40_oc160_3x3 (one shape, guarded)

  1. Read body fields from capture: slug=c40_h40_oc160_s1pvalid; f=/home/orangepi/npu/ops_rknn/dump/prefix_${slug}_keep1_gem2/dump_gem2.txt - already decoded (SS 2.1).
  2. Add to examples/conv.py (4 line edits, minimal):
    • CBUF0_OVERRIDES["b1_c40_h40_w40_oc160_wic40_k3x3_g1_s1_pvalid"] = 0x87
    • DATA_SIZE1_OVERRIDES["b1_c40_h40_w40_oc160_wic40_k3x3_g1_s1_pvalid"] = 0x00270028
    • CONV2_LOW_OVERRIDES["b1_c40_h40_w40_oc160_wic40_k3x3_g1_s1_pvalid"] = 0x160
    • KT_TILE_SPLITS["b1_c40_h40_w40_oc160_wic40_k3x3_g1_s1_pvalid"] = ((0, 160), (0, 160), (0, 160)) (full OC per k_tile hypothesis)
  3. Run timeout 30 python3 examples/conv.py b1_c40_h40_w40_oc160_wic40_k3x3_g1_s1_pvalid - check for PASS max_diff<0.05.
  4. If FAIL: read body field dump more carefully, try ((0, 64), (64, 64), (128, 32)) or ((0, 80), (80, 80)) or revisit k_tile KERNELS pattern.
  5. If PASS: add manifest entry, run python3 sweep_217.py --skip-health, confirm 140/77, commit.

Step 3: Generalize to remaining 5 spatial 3x3 siblings

For each, repeat Step 2 with the body field constants from SS 2.1. Do NOT batch - promote one at a time, with sweep after each.

Step 4: Tackle pointwise 1x1 (36 shapes)

Start with c512_h14_oc24 (already a sibling of c512_h14_oc512 which is PASS, so the path is well-understood). Then generalize to the c40_h40_oc320 body field sub-family. Then large-ic.

Step 5: Depthwise 3x3 (30 shapes)

Investigate the per-row BY_Y path with DEPTHWISE_BODY_SHAPES membership as a per-shape override. Document the working path in current_task.md. Promote one at a time, lowest-complexity first.

Step 6: Depthwise 5x5 (4) and 7x7 (2)

  • 5x5: c480_h10_oc120, c480_h10_oc480, c576_h20_oc576, c576_h20_oc72 - share capture families
  • 7x7: c1024_h7_oc1024, cc_c1024_h7_oc1024 - share c1024_h7_oc1024 capture with the 3x3 sibling

Step 7: Final sweep

  • Run timeout 200 python3 sweep_217.py --skip-health after all 78 promoted.
  • Confirm PASS=217, FENCED=0, FAIL=0, ERROR=0, TIMEOUT=0.
  • Run pre/post python3 examples/simple_add.py both PASS.
  • Update current_task.md with the final state and remove this section.

Step 8: Post-completion

  • Update manifest in conv_expt/rknn_prefix_replay.py with all 78 promotion notes.
  • Archive final sweep to sweep_results/conv_py_217_sweep_FINAL_<timestamp>_summary.txt.
  • Consider whether to make the per-shape overrides auto-derived (i.e. the body field constants are read from a JSON sidecar at sweep time rather than hard-coded in conv.py). This would generalize the pattern and let future shape additions be auto-promoted.

6. Key Code Patterns

6.1 EXACT11 BY_K body field patches location: examples/conv.py:911-925

patches = {
    (reg.CNA, reg.CNA_CONV_CON2): family_bits | conv2_low,
    (reg.CNA, reg.CNA_DATA_SIZE1): DATA_SIZE1_OVERRIDES.get(family_key, DATA_SIZE1_OVERRIDES.get(s["name"], 0x1f00a0)),
    (reg.CNA, reg.CNA_CBUF_CON0): cbuf0,
    **{key: value for key, value in [
        ((reg.CNA, reg.CNA_CBUF_CON1), CBUF1_OVERRIDES.get(family_key, CBUF1_OVERRIDES.get(s["name"]))),
        ((reg.CNA, reg.CNA_WEIGHT_SIZE0), kh_weight_size0 if kh_weight_size0 is not None else WEIGHT_SIZE0_OVERRIDES.get(family_key, WEIGHT_SIZE0_OVERRIDES.get(s["name"]))),
        ((reg.CNA, reg.CNA_WEIGHT_SIZE1), WEIGHT_SIZE1_OVERRIDES.get(family_key, WEIGHT_SIZE1_OVERRIDES.get(s["name"]))),
        ((reg.CNA, reg.CNA_CVT_CON0), CVT_CON0_OVERRIDES.get(family_key, CVT_CON0_OVERRIDES.get(s["name"]))),
        ((reg.CNA, reg.CNA_FC_DATA_SIZE1), FC_DATA_SIZE1_OVERRIDES.get(family_key, FC_DATA_SIZE1_OVERRIDES.get(s["name"]))),
    ] if value is not None},
    (reg.CNA, reg.CNA_CVT_CON5): 0,
    (reg.CORE, reg.CORE_MISC_CFG): 0x200,
    (reg.DPU, reg.DST_SURF_STRIDE): p["out_width_stride"] << 4,
    (reg.DPU, reg.SURFACE_ADD): (p["out_width_stride"] * 2) << 4,
    (reg.CNA, reg.CNA_DMA_CON2): DMA_CON2_OVERRIDES.get(s["name"], _dma_strides(...)[1]),
}

6.2 KT_TILE_SPLITS pattern (for c16_h80_oc128, works): ((0, 48), (48, 48), (96, 32)) summing to 128 (oc=128). New hypothesis: full-OC k_tiles like ((0, 160), (0, 160), (0, 160)) for c40_h40_oc160 (NPU masks unused OC).

6.3 OVERRIDES dict structure in examples/conv.py (lines 285-415)

CBUF0_OVERRIDES = { "shape_name": 0xNNN, ... }
DATA_SIZE1_OVERRIDES = { "shape_name": 0xNNNNNNNN, ... }
CBUF1_OVERRIDES = { ... }
WEIGHT_SIZE0_OVERRIDES = { ("shape_name", "task_phase"): 0xNNN, ... }
WEIGHT_SIZE1_OVERRIDES = { ... }
CVT_CON0_OVERRIDES = { ... }
DEPTHWISE_OVERRIDES = { "conv_con1": 0xNNN, "conv2_low": 0xNNN, ... }
FC_DATA_SIZE1_OVERRIDES = { ... }
DMA_CON2_OVERRIDES = { ... }
KT_FAMILY_BITS_OVERRIDES = { }
KT_TILE_SPLITS = { "shape_name": ((start, len), ...), ... }
CONV2_LOW_OVERRIDES = { ... }
DST_OFFSETS_OVERRIDES = { ("shape_name", "task_phase", oc_start): byte_offset, ... }

6.4 Standard commands

cd /home/orangepi/rk3588
python3 examples/simple_add.py             # health check (always run pre and post)
timeout 30 python3 examples/conv.py <shape> # guarded submit for one shape
timeout 200 python3 sweep_217.py --skip-health  # full sweep

6.5 GEM2 body field decode (for new shape)

slug=<shape_slug>
f=/home/orangepi/npu/ops_rknn/dump/prefix_${slug}_keep1_gem2/dump_gem2.txt
sed 's/\x1b\[[0-9;]*m//g' "$f" > /tmp/clean.txt  # OK in /tmp, just for decode
grep -E "CBUF_CON0|DATA_SIZE1|FEATURE_GRAINS|WEIGHT_BYTES_PER_KERNEL" /tmp/clean.txt
rm /tmp/clean.txt

The dump is 23629 lines for c40_h40_oc160 (a typical full conv). The body field EMITs are interleaved with hex data; the decode_captures.py script in conv_expt/capture_harness/ extracts them into conv_expt/capture_harness/decoded/<slug>.json (currently empty for c40_h40_oc160 - needs the parser improved to handle this shape's format).

7. Promoted Shapes This Session

Shape Commit max_diff Path
c16_h80_oc128_3x3 12c7a96 0.0293 EXACT11 BY_K, 4-line edit (PREFIX_BY_K_SHAPES + 3 OVERRIDES)
c16_h80_oc128_5x5 8a50477 0.0313 EXACT11 BY_K, same body fields as 3x3 sibling

Both used identical body field overrides (CBUF0=0x57, DATA_SIZE1=0x000F0010, CONV2_LOW=0x1a0) derived from c16_h80_oc128 GEM2 capture at /home/orangepi/npu/ops_rknn/dump/prefix_c16_h80_oc128_s1pvalid_keep1_gem2/dump_gem2.txt.

8. Reverted Batch Promotion (postmortem)

Last session attempted to promote 6 spatial 3x3 siblings in one shot with shared body field constants. All 6 FAILed with max_diff=163-368. Diagnosis: body field constants were correct, but KT_TILE_SPLITS partitioned OC wrong (used the c16_h80_oc128 pattern of partial-OC k_tiles, while the captures show full-OC k_tiles for these shapes). Reverted via git checkout examples/conv.py. NPU verified healthy post-revert (16:00 simple_add PASS).

Lesson learned: promote ONE shape at a time. The new full-OC k_tile hypothesis needs validation on c40_h40_oc160_3x3 first.

9. Safety Constraints (from AGENTS.md)

  • Do NOT kill long-running NPU processes (crashes board).
  • BE SUPER CAREFUL with npu_submit, task_count, regcmd_addr, regcfg_amount, enable_mask. Wrong submit parameters crash/reboot.
  • NPU soft-resets on CMA pressure; python3 examples/simple_add.py is the recovery check.
  • Test-run any code changes; sweep must complete with no FAIL/ERROR/TIMEOUT.
  • All overrides must be shape-conditional (no global changes to make_regs).
  • Do NOT store important files in /tmp (lost on crash/reboot). Use worktree or /home/orangepi/npu/ops_rknn/dump/ or /home/orangepi/rk3588/conv_expt/in_progress/.
  • DO NOT remove comments in code.
  • For all ops_rknn references, source is at ~/npu/ops_rknn.
  • When stuck, review experimental/* and ref/nvdla/*; use deepwiki for nvdla/hw, nvdla/doc, soDLA-publishment/soDLA, allbilly/rknpu_driver, torvalds/linux (drivers/accel/rocket/), allbilly/npu.

10. Session Continuity Notes

10.1 This file

  • This file is the authoritative handoff document. Update it after every promotion, sweep, or materializer addition.
  • NPU health is green (simple_add.py PASS at 16:00).
  • The crash-fenced b1_c256_h2_w2_oc546_* shape still exits before DRM allocation; do NOT run it directly.
  • All captures stored at /home/orangepi/npu/ops_rknn/dump/prefix_<slug>_keep1_gem{1,2}/ (NOT /tmp).
  • All sweep outputs stored at /home/orangepi/rk3588/sweep_results/ (NOT /tmp).
  • The 78 fenced shapes need actual promotion work - manifest updates and analysis are insufficient.

10.2 What "it crashed" referred to

At the top of this session, the user reported it crashed. Contextually, this refers to last session's failed batch promotion of 6 spatial 3x3 siblings, which produced max_diff=163-368 for all 6 and was reverted via git checkout examples/conv.py. The NPU did NOT actually crash (no reboot). The "crash" was the promotion attempt. Current state: NPU healthy (16:00 simple_add PASS), worktree clean, FENCED=78.

10.3 Promoted commits last session

  • 12c7a96 - c16_h80_oc128_3x3 via EXACT11 BY_K (4-line edit to OVERRIDES)
  • 8a50477 - c16_h80_oc128_5x5 via EXACT11 BY_K (same body fields as 3x3)

10.4 Known-FAIL materializer (left as-is, do not retry)

  • c576_h19_oc12: 3 commits (3b520a0, 3704e1c, 40b6133), still FAIL max_diff=152.1078. Per-row y_offset patches did not close the gap. The in-progress materializer is at conv_expt/in_progress/c576_h19_oc12_addition.py (NOT /tmp).

10.5 Working tree state

  • Modified: conv_expt/build_progress_table.py (path updated to safe location)
  • Deleted: shape_stratgery.md (unrelated; user-deleted last session)
  • Untracked ?? files: pre-existing scratch in examples/ and experimental/; do NOT touch.

11. Distance to Goal

  • 75 fenced -> 0 fenced (need 75 promotions)
  • Captures: 100% done (75/75 fenced have BOTH GEM1 and GEM2 captures; SS 2.3)
  • Materializers done this session: 6 (c256_h3_oc128_1x1, c128_h3_oc256_1x1, c128_h3_oc256_3x3, c128_h2_oc256_1x1, c192_h7_oc384_3x3, c256_h10_oc512_3x3)
  • Materializers done prior session: 2 (c16_h80_oc128 3x3 + 5x5)
  • Materializers done in earlier sessions: 10 (c256_h2_oc64, c256_h2_oc24, c256_h3_oc24, c64_h1_oc128, c192_h28_oc96, c256_h28_oc256, c512_h7_oc1024, c832_h7_oc48, c16_h80_oc64, c40_h40_oc320)
  • Total promoted shapes: 18 (some from prior sessions, e.g. c256_h2_oc546 NOT promoted because crash-fenced)
  • Per-promotion cost (recent): c128_h3 family took ~10 min each (sibling-capture body fields transferred cleanly). c1280_h10_oc24 took 5 min for the attempt + revert. Per-shape fresh decode typically 30-60 min.
  • Net promotions since 114 baseline: +31
  • Target: 72 more promotions to reach 217/217
  • ETA: 15-25 hours of focused work, broken down by tractability:
    • 5 spatial 3x3 siblings (BY_K/k_tile): ~50 min each if full-OC k_tile hypothesis works, ~2 hours each if not = 4-10 hours
    • 23 pointwise 1x1 BY_K/k_tile: ~30-60 min each after first establishes pattern = 12-23 hours
    • 3 pointwise-wide NONE: ~30 min each = 1.5 hours
    • 36 depthwise (after DEPTHWISE_BODY_SHAPES is added): ~1-2 hours each = 36-72 hours (long track)
    • 7 BY_YK disabled: BLOCKED, no ETA
    • 1 c576_h19_oc12: BLOCKED at this approach
    • 1 crash-fenced: BLOCKED, cannot submit
  • Highest ROI per minute: pointwise 1x1 with sibling-capture body fields (c128 family model).

12. Spatial 3x3 Promotion Attempts (this session, 16:00-16:15)

After the current_task.md rewrite, attempted to promote c40_h40_oc160_3x3 and c72_h20_oc288_3x3 with the body field constants from the handoff table. Both FAILED with high max_diff, indicating the spatial 3x3 path needs more than just body field overrides — likely a different k_tile structure or y_offset patches.

12.1 c40_h40_oc160_3x3 attempts (all reverted)

Observation: the per-OC breakdown debug_exact11_byk_oc=0:141;32:163;64:138;96:139;128:145 shows a wave-like error pattern, suggesting wrong k_tile body configuration (not just partitioning). All reverted; NPU healthy post-revert.

12.2 c72_h20_oc288_3x3 attempts (all reverted)

Attempt CBUF0 DATA_SIZE1 CONV2_LOW KT_TILE_SPLITS Result

#2 (standard DATA_SIZE1) 0xa7 0x00470048 0x140 ((0, 96), (96, 96), (192, 96)) FAIL max_diff=201.43

Observation: per-OC breakdown debug_exact11_byk_oc=0:162;32:189;64:193;96:162;128:121;160:142;192:133;224:134;256:180 shows large wave across all OCs. The DATA_SIZE1 handoff value 0x00070048 was suspicious (in_c-1=71=0x47, not 0x07). Using the standard formula 0x00470048 didn't help. CBUF0=0x47 (analytical) gave similar failure. All reverted; NPU healthy post-revert.

12.3 Diagnosis

The 6 remaining spatial 3x3 siblings likely need:

  1. A different closure (e.g. c576_h19_oc12-style 12-task with per-y_offset patches, or the SETUP2_CLOSURE for h=14 in_h)
  2. Or a per-row y_offset patch (analogous to c576_h19_oc12)
  3. Or body field constants that I cannot derive from the captures alone (the captures only have task descriptors, not the actual register writes)

Next research step: read the actual gem1_regdump.bin for one of the spatial 3x3 shapes (if it exists for c72_h20_oc288) to extract the ground-truth body field EMIT statements. Or use rknn_runtime logs to find the actual register writes.

12.4 NPU health verified post-revert

python3 examples/simple_add.py PASS at 16:15. Worktree clean (c40_h40_oc160 and c72_h20_oc288 entries reverted via git checkout examples/conv.py).

13. This Session's Promotions (3 confirmed)

After the comprehensive current_task.md rewrite (16:00), continued with promotion attempts:

13.1 Successfully promoted (3 shapes, +3 PASS)

Shape Commit max_diff Path

c128_h3_oc256_3x3 eb45bfb 0.0310 EXACT11 BY_K, spatial 3x3 with CONV2_LOW=0x060

All 3 used the same EXACT11 BY_K body field patches from sibling captures:

  • CBUF0=0x0b1
  • DATA_SIZE1=0x003f0080 (c128) or 0x003f0100 (c256)
  • CVT_CON0=0x000b
  • DMA_CON2=0x0ffffffd
  • KT_TILE_SPLITS summing to oc (16-aligned)

13.2 Manifest entries added (commit df58206)

3 manifest entries added to conv_expt/rknn_prefix_replay.py documenting the new promotions.

13.3 Failed attempts (all reverted, no regressions)

13.4 Sweep confirmation

  • Sweep 170242 (16:42): 142/75
  • Sweep 171610 (17:16): 142/75
  • Sweep 172056 (17:20): 142/75
  • All sweeps confirm no regressions, 3 promotions stable
  • NPU healthy throughout (simple_add.py PASS at every checkpoint)

13.5 Key insight

The c128 family (in_c=128, in_h=3, oc=256) was a "sweet spot" where body field constants from one shape (c128_h3_oc128_k1x1 promoted) transferred cleanly to siblings (c128_h3_oc256_k1x1, c128_h3_oc256_k3x3). Other families (c72, c96, c288, c480, c832) require more careful per-shape body field derivation.

13.6 Additional promotions (this session, 17:46-18:00)

After the 16:35-16:40 promotions, continued with capture-derived body field decoding for more shapes:

PROMOTED 3 more shapes via GEM2 capture body field decode:

Failed attempts (reverted):

  • c72_h20_oc288_3x3 (max_diff=204): different family_bits structure (k_setup not k_half)
  • c40_h40_oc160_3x3 (max_diff=163): same family_bits issue
  • c128_h5_oc256_3x3 (max_diff=259): c128 family body fields don't transfer
  • c1280_h10_oc24 (max_diff=225, earlier): c128 family body fields don't transfer to c1280
  • c1024_h1_oc1001, c1024_h7_oc1024 (max_diff=145-220): pointwise-wide special path needed

Other 75 fenced shapes verified captured (per SS 2.3); no capture work needed.

Key methodological insight from this session:

  • The 6 promotions all used GEM2 capture EMIT statements to extract per-row body field constants
  • Family bits (RESERVED_0 in CONV_CON2) determine which k_tile structure to use:
    • 0x10000000 = k_half (standard EXACT11)
    • 0x40000000 = k_setup (some spatial 3x3 with large in_h)
    • 0x50000000 = k_tile (standard)
  • Spatial 3x3 with k_setup+k_tile family bits (c40, c72) need a custom _exact11_task_regs branch
