The existing SVA and IOPF implementation assumes that devices report I/O page faults via PCI PRI. This is not always true as some emerging devices are designed to handle the I/O page faults by themselves without ever sending PCI page requests nor advertising PRI capability. Refactor the SVA and IOPF code to allow SVA support with IOPF handled either by IOMMU (PCI PRI) or device driver (device-specific IOPF). This series is based on v6.3-rc1 and also available at github: https://github.com/LuBaolu/intel-iommu/commits/intel-iommu-refactor-iopf-v2
This is iommu/vt-d specific. I should make it explicit in the cover-letter title. iommu/vt-d: Refactor code for non-PRI IOPF Sorry about it. Best regards, baolu
