[PATCH 0/7] VT-d: SATC handling and ATS tidying
Posted by Jan Beulich 2 weeks, 6 days ago
On a Sapphire Rapids system I noticed a line in the serial log
indicating a DMAR entry type we're not recognizing. While arranging
for it to be both recognized and respected, I noticed some further
potential for cleaning up.

1: VT-d: parse ACPI "SoC Integrated Address Translation Cache Reporting Structure"s
2: IOMMU: rename and re-type ats_enabled
3: VT-d: respect ACPI SATC's ATC_REQUIRED flag
4: VT-d: replace find_ats_dev_drhd()
5: VT-d: move ats_device() to the sole file it's used from
6: VT-d: move dev_invalidate_iotlb() to the sole file it's used from
7: VT-d: move {,un}map_vtd_domain_page()
