Amendments per Sonnet architect review round 1:
- A1: 0007 v2 rewritten — 7 per-codec run() insertion points,
matches hantro pattern (after preamble metadata copy, before HW kick).
Old v1 (in rkvdec_device_run) REJECTED — wrong structural placement.
- A2: panthor ww_mutex/dma_resv contention added as primary hypothesis H1.
Smoke test 1.9/2.x extended to exercise GPU compositor path.
- A3: CONFIG_LOCALVERSION=-lockdep so lockdep kernel uname differs from
vanilla — prevents modules_install overwriting working tree.
- A4: pstore/serial gate is now HARD (one-of required); pre-flight aborts
if neither serial nor ramoops is functional.
- A5: PROVE_RCU removed from initial config — boot latency risk pushes
past watchdog before lockdep prints. Add back only if first run clean.
0007-v2 patch attached: 8 hunks across rkvdec-{h264,hevc,vdpu381-h264,
vdpu381-hevc,vdpu383-h264,vdpu383-hevc,vp9}.c + rkvdec.c queue_init flag.
25 lines insertions.
Pending Phase 5 round 2 delta-review of v2 source + amended plan before
any execution.
