Subject: [Qemu-devel] [PATCH 15/15] i386: kvm: filter CPUID leaf 7 based on GET_SUPPORTED_CPUID, too
Date: Thu, 4 Oct 2012 17:49:07 -0300 [thread overview]
Message-ID: <1349383747-19383-16-git-send-email-ehabkost@redhat.com> (raw)
In-Reply-To: <1349383747-19383-1-git-send-email-ehabkost@redhat.com>
Now that CPUID leaf 7 features can be enabled/disabled on the
command-line, we need to filter them properly using GET_SUPPORTED_CPUID,
at the same place where other features are filtered out.
