How can I check the memory usage of NPU or GPU on i.MX 8M Plus evk board?

[dpcivl]

Hello. I have a question with vx delegate.

Using my i.MX 8M Plus evk board, I wonder if I can check my NPU usage while detecting objects.

I'm using efficientDet Model and the VX Delegate won't support its operation.
(unsupported op 32 issue)

So I always make XNNpack delegate.

With CPU, I want to know how many resources NPU and GPU are using while object detection.

Is there any solution for checking my usage with NPU or GPU?

You can check information like this:

root@imx8mp-lpddr4-evk:/sys/kernel/debug/gc# ls
clients  clk  database  database64x  dump_trigger  idle  info  load  meminfo  poweroff_timeout  version  vidmem  vidmem64x
root@imx8mp-lpddr4-evk:/sys/kernel/debug/gc# cat load
core      : 0
load      : 0%

core      : 1
load      : 0%

root@imx8mp-lpddr4-evk:/sys/kernel/debug/gc# cat meminfo
