Subject: [PATCH v2 0/7] Support for running as a pKVM protected guest
Date: Fri, 30 Aug 2024 14:01:43 +0100 [thread overview]
Message-ID: <20240830130150.8568-1-will@kernel.org> (raw)
Hi all,
This is version two of the series previously posted here:
https://lore.kernel.org/r/20240730151113.1497-1-will@kernel.org
Changes since v1:
* New patch allocating additional hypercalls for future pKVM usage
It looks like the CCA series is now using some of the pieces here [1],
so it would be great to merge this with an Ack from the kvmarm
maintainers.
Cheers,
Will
