# Note for EPEL users

The stock EL8 (RHEL/CentOS/CentOS Stream) kernel has PSI support compiled
|
||
|
|
into the kernel but disabled by default.
|
||
|
|
|
||
|
|
You will need to pass `psi=1` on the kernel command line, see
|
||
|
|

To persist, add this to `/etc/default/grub` to the `GRUB_CMDLINE_LINUX`
|
||
|
|
string and rebuild the GRUB config by running this as root:
|
||
|
|
|
||
|
|
`grub2-mkconfig -o /etc/grub2-efi.cfg`
