Subject: [PATCH 0/3] Add ACS quirk for Zhaoxin
Date: Fri, 27 Mar 2020 17:11:45 +0800 [thread overview]
Message-ID: <20200327091148.5190-1-RaymondPang-oc@zhaoxin.com> (raw)
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
