Subject: [PATCH v7 0/2] x86/sev: Fixes for SEV-ES Guest Support
Date: Fri, 18 Jun 2021 13:54:07 +0200 [thread overview]
Message-ID: <20210618115409.22735-1-joro@8bytes.org> (raw)
From: Joerg Roedel <jroedel@suse.de>
Hi,
please find here the next iteration of my pending fixes for SEV-ES
guest support in Linux. This version addresses the comments I received
from Peter on the previous version, in particular:
- Removed IRQ disable/enable calls in the ap-hlt loop code
- Made __sev_get/put_ghcb() noinstr instead of __always_inline
and put instrumentation_begin()/end() calls around panic()
to fix an objtool warning.
- Split up #DB handling in the #VC handler into a from-user
and from-kernel part as well.
The patches are again tested with a kernel with various debugging
options enabled, running as an SEV-ES guest.
The previous version of these patches can be found here:
https://lore.kernel.org/lkml/20210616184913.13064-1-joro@8bytes.org/
Please review.
Thanks,
Joerg
