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
