rpi-gpu-usage: Report csd and cache_clean queues - #210
Merged
Conversation
V3D has six job queues but only render, tfu and bin were mapped in engine_idx(), so samples for any other queue were silently discarded. Compute workloads run entirely on the csd (compute shader dispatch) queue and never touch render or bin. That made them completely invisible: an ML inference job saturating the GPU showed render, tfu and bin all at 0.0% alongside 100% CPU, which reads as "not using the GPU at all" when the opposite is true. The global gpu_stats sysfs file already reported the same work as csd at 99.8% busy. Add csd and cache_clean, and narrow the PID and Process columns so the two extra columns still fit in an 80-column terminal (78 chars used).
