Subject: [Qemu-devel] [PATCH 2/2] target-i386: automatically raise cpuid level to 0xd
Date: Thu, 18 Jun 2015 17:24:24 +0200	[thread overview]
Message-ID: <1434641064-8405-3-git-send-email-rkrcmar@redhat.com> (raw)
In-Reply-To: <1434641064-8405-1-git-send-email-rkrcmar@redhat.com>

We already bump to level 7 if features there are requested, so do the
same for 0xD.

Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>

 If we want this behavior, we should not do it by writing a case for
 every level.
