Subject: [Qemu-devel] [PATCH 2/8] target-ppc: ppc64 target's virtio can be either endian.
Date: Mon, 12 Aug 2013 17:29:22 +0930 [thread overview]
Message-ID: <1376294363-4650-3-git-send-email-rusty@rustcorp.com.au> (raw)
In-Reply-To: <1376294363-4650-1-git-send-email-rusty@rustcorp.com.au>
We base it on the OS endian, as reflected by the endianness of the
interrupt vectors.
