Subject: [PATCH 0/4] enable ATS per pcie root port, not globally
Date: Mon, 22 Aug 2022 14:34:33 +0530 [thread overview]
Message-ID: <20220822090438.426748-1-ani@anisinha.ca> (raw)
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
