Subject: [PATCH v4 0/2] x86/sev: Fix AP Jump Table handling for SNP guests
Date: Tue, 26 Apr 2022 09:21:45 -0500 [thread overview]
Message-ID: <20220426142147.338412-1-michael.roth@amd.com> (raw)
This series is based on tip/master (commit 1912a07f8a)
SNP guests should only retrieve the AP Jump Table address from the
secrets page, not via a GHCB request as with SEV-ES guests. This series
reworks the handling accordingly, and fixes up some __init annotations
for some of the SEV routines touched by that rework.
v4:
- Improve commit msg for patch 2 (Tom)
v3:
- Address missing __init annotations (Boris)
v2:
- add handling for memremap()/ioremap() failures (Boris)
- don't mix function calls with declarations (Boris)
