Subject: [PATCH 0/5] SEV fixes and performance enhancements
Date: Thu, 3 Oct 2019 21:17:42 +0000 [thread overview]
Message-ID: <cover.1570137447.git.thomas.lendacky@amd.com> (raw)
From: Tom Lendacky <thomas.lendacky@amd.com>
This patch series provides fixes in the area of ASID assignment and VM
deactivation.
Additionally, it provides some performance enhancements by reducing the
number of WBINVD/DF_FLUSH invocations that are made.
Note: The third patch in the series modifies a file that is outside of
the arch/x86/kvm directory.
