Hi Alex
Going through the PCIe Spec, there seems a lot of such capabilities
that are different between PF and VF. Some that make sense
and some don't.

Hi Alex

FWIW I can't understand why PCI SIG went different ways with ATS,
where its enumerated on PF and VF. But for PASID and PRI its only
in PF.
I'm checking with our internal SIG reps to followup on that.

From: Liu Yi L
Per PCIe r5.0, sec 9.3.7.14, if a PF implements the PASID Capability, the
PF PASID configuration is shared by its VFs. VFs must not implement their
own PASID Capability.
Per PCIe r5.0, sec 9.3.7.11, VFs must not implement the PRI Capability. If
the PF implements PRI, it is
