Subject: [PATCH v2 0/4] x86/sev: Rework SNP Guest Request
Date: Wed, 11 Jun 2025 14:08:38 +1000 [thread overview]
Message-ID: <20250611040842.2667262-1-aik@amd.com> (raw)
Started as a part of the fix for
ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex")
these are the remainder of followup fixes/improvements as
the SNP Guest Request code evolved enough to make it a bit hard to
follow.
Changes:
v2:
* added RBs
* adjusted grammar
* rebased on top of v6.16-rc1
The previous conversation is here:
https://lore.kernel.org/r/20250505141238.4179623-1-aik@amd.com
This is based on sha1
19272b37aa4f Linus Torvalds "Linux 6.16-rc1".
Please comment. Thanks.
