I wanted to find out if my Linux server supports PCI passthrough. For that, I need to know if my CPU has VT-d or IOMMU enabled or not, but I couldn't find the way.
The following is the lscpu
command output:

By inspecting the specs for my Intel CPU, I did find out that it supported the VT-d, but I would be glad if anyone could give any command for directly knowing if the CPU supports the same.
My Linux distro is CentOS 7.9
Thank you for the answers.
