Subject: [PATCH v1 0/2] MMIO mask fix for AMD memory encryption support
Date: Wed, 18 Dec 2019 13:45:45 -0600 [thread overview]
Message-ID: <cover.1576698347.git.thomas.lendacky@amd.com> (raw)
This patch series ensures that a valid MMIO SPTE mask can be generated

The patchset includes:
- Add an optional callback to return a reserved bit(s) mask
- Implement the callback in SVM
