[Solved]Can't enable iommu on laptop

el_billy · 2019-05-02 22:58:32

Hi!
This is my first post but im using arch for a while...

Im trying to enable iommu on my laptop without suscess
My specs

Asus Gl553vd (with unlocked BIOS)
Processor Core i7-7700HQ - VT-d capable

I have no iommu's groups on /sys/kernel/iommu_groups and cant find IOMMU enable in dmesg

I have enable in vt-d and vmx on bios.

any ideas?

kernel parameters:

rw audit=0 intel_iomu=on  intremap=no_x2apic_optout net.ifnames=0 nouveau.modeset=0 acpi_osi=Linux rd.driver.blacklist=nouveau nmi_watchdog=0

dmesg | grep -e DMAR -e IOMMU

Does it need to also be set in grub?

I found this on an ubuntu forum

"Set intel_iommu=on in the grub command line (edit /etc/default/grub and then "sudo update-grub" after saving the changes)
Rebooted after the above"

https://ubuntuforums.org/showthread.php?t=2322179

Edit: There's also this kernel parameter..

iommu=pt

https://community.mellanox.com/s/articl … figuration

Is iommu misspelled in your current kernel parameters?
