[PATCH 0/4] enable ATS per pcie root port, not globally

Posted by Ani Sinha 1 year, 8 months ago

This is towards a possible fix for RedHat ticket
https://bugzilla.redhat.com/show_bug.cgi?id=2089545 . 

Michael suggested we try to enable ATS per pcie root port instead of enabling it
globally by setting the ALL_PORTS flag to 1 in the Root Port ATS capability structure.
This patchset makes this happen.


Ani Sinha (4):
  hw/acpi: allow changes to DSDT and DMAR tables
  hw/acpi: set ATS capability explicitly per pcie root port
  tests/acpi/bios-table-test: add pcie root port device for DMAR test
  tests/acpi/bios-tables-test: update DSDT and DMAR table blobs
