Subject: [Qemu-devel] [PATCH 1/4] convert cpuid registration to KVM_SET_CPUID2
Date: Thu, 29 Jan 2009 12:19:26 -0500 [thread overview]
Message-ID: <1233249569-16686-2-git-send-email-glommer@redhat.com> (raw)
In-Reply-To: <1233249569-16686-1-git-send-email-glommer@redhat.com>
Use KVM_SET_CPUID2 instead of KVM_SET_CPUID. This
will allow us to do registration of cpuid leaves without
multiple calls to the kernel in the future.
