From dc66b325f161bb651493c7d96ad44876b629cf6a Mon Sep 17 00:00:00 2001 From: Michel Dänzer Date: Thu, 7 Apr 2011 16:17:47 +0200 Subject: radeon: Fix KMS CP writeback on big endian machines. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is necessary even with PCI(e) GART, and it makes writeback work even with AGP on my PowerBook. Might still be unreliable with older revisions of UniNorth and other AGP bridges though.
