Hi Loic:
A little more clarification, as I dug in deeper.
I was wrong on the cpu type. It is an Intel cpu.
But led me astray was the uname and the /proc/cmdline:
uname: Linux enough 5.10.0-5-amd64 #1 SMP Debian 5.10.24-1 (2021-03-19) x86_64
GNU/Linux
/proc/cmdline: BOOT_IMAGE=/vmlinuz-5.10.0-5-amd64 root=/dev/mapper/enough--vg-root ro
quiet
But looking at the lscpu, I do see it's an Intel cpu. (Sorry for not looking at that
first before sent my earlier reply.)
It appears the Debian amd64 kernel does not support the perf events needed for this.
Is it possible for you to run this on a recent CentOS-8 OS version?
I also see the system you used is a small, desktop level system with only 4 cpus (2
cores). If you can get a larger server, you should see more contention, which would help
with this effort.
Thanks,
Joe
