Hey there. Sorry, I misread the relevant code and thought that you were
constantly spawning and killing the nvidia-smi process. IIUC that is not the
case, you're just running `nvidia-smi pmon` in the background and parsing its
output. This bypasses the common problem other monitoring tools had where the
setup/teardown was causing the issue.
But, I now see where just `nvidia-smi pmon` can be a cause of stutter, because
it is fetching a lot of data out of the GSP via
NV2080_CTRL_CMD_PERF_GET_GPUMON_PERFMON_UTIL_SAMPLES_V2. Switching to NVML
would not fix this. I'll have to look a bit deeper and see if there's a better
way to get the needed info; and/or if this can get fixed in NVML or the driver
itself.
