depends on your boot configuration. if you use systemd-boot, use kernelstub -a "i915.mitigations=off". if you have /etc/default/grub, add it as a kernel parameter then update-grub.

Just set this on my MiniPC running Debian which runs Jellyfin.

    sudo nano /etc/default/grub
Look for GRUB_CMDLINE_LINUX_DEFAULT and add: i915.mitigations=off

    GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.mitigations=off"
Then:

    sudo update-grub
    sudo reboot
To verify:

    cat /proc/cmdline
