[arch-general] Radeonhd - Use EXA Accel instead of XAA Accel

13 May 2009


      Listmates,

	If you use the radeonhd driver, use EXA acceleration instead of XAA. I just 
found out about this today and it is a 100% improvement in speed, etc. over 
XAA acceleration. It isn't as fast as fglrx, but it is a world of improvement 
over the alternative. To make use of EXA acceleration, simply enable it in 
your xorg.conf in the device section. Example:

Section "Device"
  BoardName    "RS690M"
  Driver       "radeonhd"
  Identifier   "Device[0]"
  Option       "GARTSize" "256"
  Option       "AccelMethod" "EXA"
  Option       "EnablePrivateBackZ" "no"
  Option       "VideoOverlay" "on"
  Option       "no_dri" "no"
  Option       "UseFastTLS" "1"
  Option       "no_accel" "no"
  Option       "mtrr" "off"
  VendorName   "ATI"
EndSection
