Hardware performance counters

VisionFive 2 （English Forum)
1

Hello!!

I would like to ask if there is a table concerning the hardware performance events that VisionFive2 board supports. I cannot find documentation. Also, how many counters are there for use?

Lastly, does perf utility work properly over Ubuntu? Because it seems that I am getting “not counted” results.

Thanks!!

Getting these to work is super hard on Raspberry too.

You need to be lucky to get a kernel that has them configured properly with what the apt-get gives you.
