The devices in BIOS SATC (SoC integrated Address Translation Cache) table are all trusted devices to use ATS. This patch set enables ATS for them.
--- v2: - Use dmar_find_matched_satc_unit() to avoid hard coded return value. - add static declaration for dmar_ats_supported() (the function modified from dmar_find_matched_atsr_unit()) ---
Yian Chen (2): iommu/vt-d: Enable ATS for the devices in SATC table iommu/vt-d: Declare dmar_ats_supported() as static function
