[PATCH v2 0/2] Enable ATS for the devices in SATC table

From: Yian Chen
Date: Tue Feb 22 2022 - 13:54:28 EST


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())
---

iommu/vt-d: Enable ATS for the devices in SATC table
iommu/vt-d: Declare dmar_ats_supported() as static function
