If we do not force max GPU rate (/sys/kernel/debug/bpmp/debug/clk/nvenc/mrq_rate_locked and other 10 files), then jetson starts working sometimes slowly and breaks transcoding.
When we put maximum rate, then it is not clear, how to identify current GPU load.
Is there such possibility?
Hi maxlapshin,
Please use Tegrastat to monitor the GPU workload status, see [url]Welcome — Jetson Linux<br/>Developer Guide 34.1 documentation
Thanks
How can it help if GPU rate is locked? Tegrastat shows static numbers because rate is locked.
You can still the GPU load using tegrastats. It’s called GR3D_FREQ. If you want a visualization, be sure to try jtop!

GR3D_FREQ shows 0%
Maybe something is misconfigured on local board?
What is current load of this system?
