Turning mitigations off

Post by jeenuv »

I picked up a post from Hacker News that points to this page about turning off kernel mitigrations: https://linuxreviews.org/HOWTO_make_Lin ... Intel_CPUs.

I haven't made up my mind whether or not to disable them, but if I were to do so, in which file shall I enter these kernel arguments? I reckon it'd be in one under /etc/grub.d?

Thanks for any pointers.

Kernel parameters can be added to the GRUB_CMDLINE_LINUX_DEFAULT= line in /etc/default/grub.

Be sure to

Code: Select all

sudo update-grub
after your edits.

Good luck out there... :wink: ....be interesting to know how much real world difference you notice.

By the way best to refer to the Ubuntu specific info as that article is talking about mainline kernels and the info about what parameters are needed for what kernel versions is not relevant for the Ubuntu provided kernels used by default in Mint.

mitigations=off should be all that's needed in all currently supported Ubuntu kernels.
