Hi,
I already installed two page-table isolation kernels, that aren't rt
patched kernels.
At the moment I don't have time to test if booting with or without
nokaiser/nopti does make a difference.
[root@archlinux moonstudio]# grep \ no..i /boot/syslinux/syslinux.cfg
APPEND root=LABEL=archlinux ro threadirqs nopti
APPEND root=LABEL=moonstudio ro nokaiser
[root@archlinux moonstudio]# pacman -Q linux
linux 4.14.15-1
[root@archlinux moonstudio]# systemd-nspawn apt changelog linux-image-4.4.0.112-lowlatency 2>/dev/null | grep "nokaiser"
- kaiser: add "nokaiser" boot option, using ALTERNATIVE
Does performance differ when booting 4.14.15-rt11 with or without nopti?
Regards,
Ralf
