Subject: [PATCH v2 0/4] iommu/vt-d: Some fine tuning of SVA

Hi folks,

This includes several tunings of Intel SVA implementation. I plan to
target them for v5.19. Please help to review.

Best regards,
baolu

Change log:

v2:
 - Move snoop control capability check into a separated patch.
 - Return false if the caller opt-in setting PGSNP with a flag.
 - Add a Fixes tag for "iommu/vt-d: Drop stop marker messages" as it is
   required by the iopf framework.

v1: initial post

  iommu/vt-d: Set PGSNP bit in pasid table entry for SVA binding
  iommu/vt-d: Drop stop marker messages
  iommu/vt-d: Size Page Request Queue to avoid overflow condition
