Thank you for the response, I did what you recommended and I didn’t see any difference. I enabled the VT-d (ATS, I didn’t find anything exclusively that says ATS on Aptiov) and on the drivers I enabled the ATS_ENABLED flag. I see the ATS capability structure on lspci but not the PASID capability structure.
I used other graphics card with PASID capability that is showing up on lspci in the same environment. So, I’m striking out the kernel modules/BIOS enablement/and any other environment settings.
