Subject: [PATCH 0/2] iommu/amd: Revert and remove failing PMC test
Date: Fri,  9 Apr 2021 03:58:46 -0500	[thread overview]
Message-ID: <20210409085848.3908-1-suravee.suthikulpanit@amd.com> (raw)

This has prevented PMC to work on more recent desktop/mobile platforms,
where the PMC power-gating is normally enabled. After consulting
with HW designers and IOMMU maintainer, we have decide to remove
the legacy test altogether to avoid future PMC enabling issues.

Thanks the community for helping to test, investigate, provide data
and report issues on several platforms in the field.

Regards,
Suravee
