Subject: [Qemu-devel] [PATCH v2 3/4] target-i386: add f16c and rdrand to Haswell and Broadwell
Date: Wed, 10 Dec 2014 12:06:31 +0100 [thread overview]
Message-ID: <1418209592-9373-4-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1418209592-9373-1-git-send-email-pbonzini@redhat.com>
Both were added in Ivy Bridge (for which we do not have a CPU model
yet!).
