kernel: TLB invalidate auto-complete (MMU_INVALIDATE trigger) + fn-10 queue logging
- NV_VIRTUAL_FUNCTION_PRIV_MMU_INVALIDATE (BAR0+0x30B0, TRIGGER=bit31):
driver sets TRIGGER then spins in kgmmuCheckPendingInvalidates_TU102
polling for it to clear. Our shadow held TRIGGER forever -> nv_open_q
hard-wedged in RmInitAdapter (TLB invalidate during dmaAllocMapping).
Auto-clear the trigger bit in gsp_emu_poll_boot (instant completion).
- fn-10/47 handler logs hObjectOld + cmd_read/stat_write/drv_rp/stat_seq.
Confirmed: drv_rp tracks stat_write 1:1 (driver drains cleanly, no
lapping); frees complete; stat_seq increments per record.
- Health-check/crashcat loop (kgspHealthCheck -> crashcatEngineGetNext
CrashReport never returns NULL) is a SECONDARY symptom triggered by an
RPC failure during RmInitAdapter - under investigation.
