Subject: [Qemu-devel] [PATCH 19/28] PPC: E500: Update freqs for all CPUs
Date: Sat, 23 Jul 2011 12:50:03 +0200	[thread overview]
Message-ID: <1311418212-13356-20-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1311418212-13356-1-git-send-email-agraf@suse.de>

Now that we can so nicely find out the host's frequencies, we should also
make sure that we get them into all virtual CPUs' device tree nodes.
