Subject: [PATCH 0/5] iommu/vt-d: Add page request draining support
Date: Tue, 17 Mar 2020 15:02:24 +0800	[thread overview]
Message-ID: <20200317070229.21131-1-baolu.lu@linux.intel.com> (raw)

When a PASID is stopped or terminated, there can be pending
PRQs (requests that haven't received responses) in remapping
hardware. VT-d driver must drain the pending page requests so
that the pasid could be reused. The register level interface
for page request draining is defined in 7.11 of the VT-d spec.
This series adds the support for page requests draining.

This functionality was mainly developed and tested by
	Jacob Pan <jacob.jun.pan@linux.intel.com>
	Liu Yi L <yi.l.liu@intel.com>.
Thanks a lot.

Please help to review.

Best regards,
baolu
