Hi,

When I am running pqos, I'll get the following error:

NOTE:  Mixed use of MSR and kernel interfaces to manage
       CAT or CMT & MBM may lead to unexpected behavior.
WARN: resctl filesystem mounted! Using MSR interface may corrupt resctrl filesystem and cause unexpected behaviour

Could you provide full pqos command that are you trying to execute?

Yes, sure. I used sudo pqos -t 1.

What system are you using?

I'm using Intel(R) Xeon(R) W-2275 CPU @ 3.30GHz. Also, my running os is ubuntu 20.04 LTS.

Please, provide output of the following commands

$ pqos --version

Hi,

I haven't been able to resolve this issue yet. Does it have anything to do with my CPU's model?

Thanks

It looks like reading MSR's is working, but you cannot write MSRs. But any chance does your system have Secure Boot enabled?
Can you try running the commands above using the OS interface flag?

e.g. pqos --display-verbose --super-verbose --iface-os

I checked for the secure boot settings, and it seems I got the secure boot enabled.

>> sudo mokutil --sb-state      

SecureBoot enabled

Also, the output of the pqos --display-verbose --super-verbose --iface-os is:

Please check if resctrl can be mounted manually using command
mount -t resctrl - /sys/fs/resctrl
Verify resctrl filesystem structure
tree /sys/fs/resctrl
