I don't have /etc/sysconfig/grub on Manjaro. Is it /etc/default/grub?
Should I add the line as specified in the article if my CPU is as old as Core 2 Duo? Will it make any difference? Won't it render the system unbootable?
- katsura 7y agoYou can check with this command if your CPU is affected by any of those: grep . /sys/devices/system/cpu/vulnerabilities/* And yes, you'll need to edit the /etc/default/grub file, but make sure that you add your extra parameters to GRUB_CMDLINE_LINUX_DEFAULT based on this: https://wiki.archlinux.org/index.php/Kernel_parameters#GRUB https://wiki.archlinux.org/index.php/Kernel_parameters#GRUB
- qwerty456127 7y agoThanks!
- forinti 7y agoYes. You should end up with a line like this: GRUB_CMDLINE_LINUX_DEFAULT="noresume noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off mitigations=off"
