I have access to a Xeon Silver 4310 machine which reports to have
cat_l3, cqm_mbm_local, cqm_mbm_total and mba.

I would like to test resctrl2 on it so I can better understand how it
works. I think that will help me understand how to adapt the RISC-V
CBQRI resctrl proof-of-concept to use resctrl2.

Would you be able to provide an example of how you loaded the necessary
resctrl2 kernel modules?

Also, is resctrl2_v65rc1 the latest to branch to test?

Thank you,
Drew
