Subject: [RFC 00/16] KVM: selftests: Add tests for SEV, SEV-ES, and SEV-SNP guests
Date: Tue, 5 Oct 2021 18:44:43 -0500 [thread overview]
Message-ID: <20211005234459.430873-1-michael.roth@amd.com> (raw)
These patches and are also available at:
https://github.com/mdroth/linux/commits/sev-selftests-rfc1
They are based on top of v5 of Brijesh's SEV-SNP hypervisor patches[1]
to allow for SEV-SNP testing and provide some context for the overall
design, but the SEV/SEV-ES patches can be carved out into a separate
series as needed.
== OVERVIEW ==
This series introduces a set of memory encryption-related parameter/hooks
in the core kselftest library, then uses the hooks to implement a small
library for creating/managing SEV, SEV-ES, SEV-SNP guests. This library
is then used to implement a basic boot/memory test that's run for all
variants of SEV/SEV-ES/SEV-SNP guest types, as well as a set of SEV-SNP
tests that cover various permutations of pvalidate/page-state changes.
- Patches 1-7 implement SEV boot tests and should run against existing
kernels
- Patch 8 is a KVM changes that's required to allow SEV-ES/SEV-SNP
guests to boot with an externally generated page table, and is a
host kernel prequisite for the remaining patches in the series.
- Patches 9-12 extend the boot tests to cover SEV-ES
- Patches 13-16 extend the boot testst to cover SEV-SNP, and introduce
an additional test for page-state changes.
Any review/comments are greatly appreciated!
