Can I know sampling rate of the default GPU governor on Jetson TX2, nvhost_podgov?
I could find some sysfs files related to GPU governors in /sys/devices/17000000.gp10b/devfreq/17000000.gp10b
I saw the content in file /sys/devices/17000000.gp10b/devfreq/17000000.gp10b/polling_interval is 25.
Does it mean that sampling rate of GPU governor is 25ms?
One more question.
I think if I use userspace governor, the sampling rate (polling_interval) is not applied anymore.
Is it correct?
