Revision 98873f53becea9a8a46972ff252e96fe575b120d authored by Ralf Baechle on 09 December 2008, 17:58:46 UTC, committed by Ralf Baechle on 09 December 2008, 21:55:43 UTC
Certain X11 servers such as the SIS server will only work if PCI mmap is implemented. This patch implements PCI mmap but to be on the same side so close to a release it only supports uncached mappings so performance will not be optimal for some uses such as framebuffers. Thanks to Zhang Le <r0bertz@gentoo.org> for the original report and testing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
