[PATCH 0/3] Add ACS quirk for Zhaoxin

From: Raymond Pang
Date: Fri Mar 27 2020 - 05:27:11 EST


Lots of Zhaoxin PCIe components have no ACS Capability Structure,
but do have ACS-like capability which ensures DMA isolation.
This patch makes isolated devices could be directly assigned to
different VMs through IOMMU.

PCI: Add Zhaoxin Vendor ID
PCI: Add ACS quirk for Zhaoxin's multi-function devices
PCI: Add ACS quirk for Root/Downstream Ports
