Subject: [Qemu-devel] [PULL v5 05/12] milkymist-vgafb: swap pixel data in source buffer
Date: Tue,  4 Feb 2014 19:58:27 +0100	[thread overview]
Message-ID: <1391540314-16141-6-git-send-email-michael@walle.cc> (raw)
In-Reply-To: <1391540314-16141-1-git-send-email-michael@walle.cc>

In commit fc97bb5ba3e7239c0b6d24095df6784868dfebbf the lduw_raw() call was
eliminated. But we are reading from the target buffer a 16-bit value, which
is in big-endian format. Therefore, use lduw_be_p() to read the value.
