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
