Subject[PATCH 0/2] iommu/vt-d: Add ESRTPS & ESIRTPS check
Date
Hi folks,

Some VT-d hardware implementations invalidates all DMA remapping
or interrupt remapping hardware translation caches as part of SRTP or
SIRTPS flow. The VT-d spec introduced two capability bits for these
hardware behaviors. This series fine tuned the VT-d driver to avoid
unnecessary global cache validations.

Best regards,
baolu
