About frequencies of chips on Xavier board such as CPU, ISP, Encoder, are they running at maximum frequency by default? Is there a way to let them run at higher freqency if not? Is there any documentation about device frequencies and how to set them?


Dear @leqiang.wang,
Yes. They run at maximum frequency.

Thanks Siva. Is there any documentation that shows exact max/max frequencies, and available frequencies of ISP and NVENC?
I found 3 tables in Jetson Xavier’s documentation about max frequencies, under " Supported Modes and Power Efficiency"
Is one of the tables same as the DRIVE AGX Xavier?
what are the paths under /sys/device that have the device information of ISP and NVENC?

Dear @leqiang.wang,
Jetson is different from Drive platform.
Please see /sys/kernel/debug/bpmp/debug/clk/<isp/vic/nvenc>/rate to know the frequency of each accelerator
