Hi,
how can I disable EXA and use XAA? I am on opensuse and added the following
section to /etc/X11/xorg.conf.d/50-device.conf:
Section Device
Option AccelMethod xaa
Identifier Default Device
EndSection
Xorg reads the file because it says in its logfile:
[ 21.481] (==) RADEON(0): Depth 24, (--) framebuffer bpp 32
[ 21.481] (II) RADEON(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp
pixmaps)
[ 21.481] (==) RADEON(0): Default visual is TrueColor
[ 21.481] (**) RADEON(0): Option AccelMethod xaa
[ 21.481] (==) RADEON(0): RGB weight 888
[ 21.481] (II) RADEON(0): Using 8 bits per RGB (8 bit DAC)
[ 21.481] (--) RADEON(0): Chipset: ATI Radeon Mobility X300 (M22) 5460
(PCIE) (ChipID = 0x5460)
[ 21.481] (II) RADEON(0): PCIE card detected
But EXA is still used:
[ 21.481] (II) Loading sub module exa
[ 21.481] (II) LoadModule: exa
[ 21.482] (II) Loading /usr/lib/xorg/modules/libexa.so
[ 21.488] (II) Module exa: vendor=X.Org Foundation
[ 21.488] compiled for 1.10.4, module version = 2.5.0
...
[ 21.575] (II) RADEON(0): EXA: Driver will allow EXA pixmaps in VRAM
...
[ 21.635] (II) RADEON(0): Setting EXA maxPitchBytes
[ 21.635] (II) EXA(0): Driver allocated offscreen pixmaps
[ 21.635] (II) EXA(0): Driver registered support for the following
operations:
[ 21.635] (II) Solid
[ 21.635] (II) Copy
[ 21.635] (II) Composite (RENDER acceleration)
[ 21.635] (II) UploadToScreen
[ 21.635] (II) DownloadFromScreen
How can I disable EXA and use XAA?. I suspect EXA to be responsible for a
huge performance regression.
XAA is not compatible with KMS.
