cpuinfo_init() error -22

[w0x7c00]

Hi, Can you help me with this error :

NOTE: Mixed use of MSR and kernel interfaces to manage CAT or CMT & MBM may lead to unexpected behavior. ERROR: cpuinfo_init() error -22 Error initializing PQoS library!

This is my cpuinfo:

Can you post the command used to produce this error? Also, please make sure you are running the command with root privilege's.

Hi, This is the command:

root@n138-025-201:~# pqos -d NOTE: Mixed use of MSR and kernel interfaces to manage CAT or CMT & MBM may lead to unexpected behavior. ERROR: cpuinfo_init() error -22 Error initializing PQoS library!

[mdcornu]

Could you provide the pqos library, OS and kernel version you are using please?

[mdcornu]

Also, the output from pqos -Vs and if you built the tools yourself, it may be helpful to rebuild with debugging info make DEBUG=y.

Linux version 5.4.56.bsk.2-amd64 Debian 9

We have found issue with OS interface detection. In some cases library doesn't fallback to MSR interface.

INFO: Requested interface: AUTO
INFO: resctrl not detected. Kernel version 4.10 or higher required
INFO: Selected interface: AUTO

Selected interface is AUTO. You can force pqos to use MSR interface by adding --iface=msr parameter. Example pqos --iface=msr -d

Thanks for your reply, now everything works will.
