Three things back, one of them a bug in the script. First, it works: pointed at your geom corpus it produces the full report, 415 lines, no warnings. Thank you for writing it in a way that runs anywhere - only numpy, and the parts that need your files skip themselves cleanly. Second, the bug. Point it one directory higher, at a corpus that also contains files outside the geometry set, and it dies: File "reserved0-build.py", line 431, in dump % (o["off"], o["v"], o["RESERVED_0"], KeyError: 'v' The cause is small and I think you will spot it faster than I can describe it. read_ops() gives an undecoded dispatch a short dict - dict(off=off, undecoded=True), no "v", no "RESERVED_0". Everywhere else you are careful about that: the good/bad split, the row groups, the per-file value sets, and the "mixed" comprehension itself all filter on "if not o['undecoded']". dump() is the one place that walks f["ops"] straight through, so the first undecoded dispatch in a dumped file raises. It needs a corpus where a file has both more than one RESERVED_0 and at least one undecoded dispatch. In mine that is exactly one file out of thirteen: chain, with 2 undecoded dispatches out of 26. It lands in "others", so dump(others[0]) hits it. Skipping undecoded ops in dump(), or printing them as a short "undecoded" line, is all it takes. Third, the corpus I owe you. I have not collected it yet, and I do not want to give you a date I am not sure of. To be precise about where it stands: every .rknn on this disk is still yours - 103 files, and all 103 declare the same build string, 2.3.2 (@2025-04-03T08:26:16). So the axis I offered to test, whether 34/66 <-> 0x4044 survives a different toolkit version, is still untested. It is on my list, behind the DVFS series review. One more thing, unrelated to the script, from your earlier mail: the /dev/accel/accel2 you saw after two rebind cycles is the same thing I hit on RK3588, where the minor walked 1 -> 10 over ten cycles and only rmmod reset it. I traced it in the source afterwards: rocket_device_init() allocates the DRM device with devm on the shared rknn platform device, which is only unregistered at module removal, so each unbind leaves a drm_device alive holding its minor. You do not need a new patch for it - it is already written and waiting: [PATCH v2 1/2] accel/rocket: release the shared device's devres on teardown https://lore.kernel.org/all/20260731064933.12548-2-royalnet026@gmail.com/ That series has your Reviewed-by on 2/2 already. If you rebind on RK3576 often, that patch is worth carrying locally in the meantime. Thanks again for the script.
