How to enable resctrl? #184

Closed dxlet closed 3 years ago

dxlet commented 3 years ago

I cannot enable resctrl， same as the problem #179 My kernel is 5.11.16-1.el7.elrepo.x86_64 , OS is centos-release-7-9.2009.1.el7.centos.x86_64, CPU is intel gold 6278C.

# ls /sys/fs/
bpf  cgroup  pstore  selinux  xfs

I have read #108, #152 and https://github.com/intel/intel-cmt-cat/wiki. I have tried to pass kernel command line parameters by modifying /boot/grub2/grub.cfg. The parameters can be seen in /proc/cmdline, but i still can't use resctrl. What is wrong with my method of starting resctrl?

# cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-5.11.16-1.el7.elrepo.x86_64 root=/dev/mapper/centos-root ro crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet rdt=mba
