Subject: [PATCH 5/7] target/i386: TCG supports XSAVEERPTR
Date: Sun, 18 Jun 2023 23:51:12 +0200	[thread overview]
Message-ID: <20230618215114.107337-6-pbonzini@redhat.com> (raw)
In-Reply-To: <20230618215114.107337-1-pbonzini@redhat.com>

XSAVEERPTR is actually a fix for an errata; TCG does not have the issue.
