Subject: [PATCH v2 0/2] iommu/vt-d: pfsid fix
Date: Thu, 7 Jun 2018 09:56:58 -0700 [thread overview]
Message-ID: <1528390620-31565-1-git-send-email-jacob.jun.pan@linux.intel.com> (raw)
When device invalidation throttling(DIT) is supported by an IOMMU, device TLB
invalidation should include physical function source ID(PFSID).
Changes since v1:
- Fixed compile error when CONFIG_PCI_ATS is not set
- Simplified how PF source ID is retrieved
