Unable to Enable SVA for Intel DSA on Ubuntu with Kernel 6.2.0-34-generic

Aj1991 — Fri, 10 Nov 2023 02:55:36 GMT

Hello,

I am attempting to use Intel DSA on Ubuntu, kernel version 6.2.0-34-generic. The idxd driver is loaded but reports "Unable to turn on user SVA feature" in the dmesg log. I've set intel_iommu=on in my GRUB config, yet the output from /sys/bus/dsa/devices/dsa0/pasid_enabled shows that PASID is disabled (0). I've been unable to find any PASID or related virtualization options in my system's BIOS settings. Could you advise on how to enable SVA or if there's a workaround for systems without explicit BIOS support for these features?

Thank you for any help you can provide.
