Subject: [PATCH 0/6] Add initial GHCB support for SEV-ES selftests
Date: Tue, 9 Apr 2024 06:39:53 -0700 [thread overview]
Message-ID: <20240409133959.2888018-1-pgonda@google.com> (raw)
Adding GHCB support for selftests. Very similar code to the ucall
functionality, I didn't refactor anything common out since I was unsure
with just two instances that is required. If pulling out common code
between those two is preferred please let me know. The series only adds a
single usage of the GHCB which is a special outsb GHCB exit to allow for
passing the 64-bit ucall pointer. In future series we can test more GHCB
functionality of KVM. I'd like to base some SNP smoke tests off of this
and the current SEV selftest work.
