Subject: [PATCH v1 0/4] SEV re-initialization fixes
Date: Mon, 27 Apr 2026 10:15:03 -0600	[thread overview]
Message-ID: <20260427161507.32686-1-tycho@kernel.org> (raw)

From: "Tycho Andersen (AMD)" <tycho@kernel.org>

Here is a series targeted at fixing the bug where HSAVE_PA is cleared
after other VMs are running that Sashiko pointed out.

The first three patches are relatively straightforward, I think :). The
last one is an ABI break from how things used to work.

Thanks,

Tycho
