(i.MX53 QSB) How to improve the performance of 3D graphics on 2nd display

Discussion created by Samaya Lin on Aug 30, 2012
The test lucid image is from imx53qsb_ubuntu_sd.img. 
After configuring the system to dual display with imx driver,
run es11ex to get the 3D graphics performance.
The performance on 2nd display is must slower than
main display, is it possible to improve it ?

The test procedure are :
A.  Update the related packages to 11.09 on lucid. 
Including amd-gpu-x11-bin-mx51_11.09.01-1_armel.deb,
xserver-xorg-video-imx_11.09.01-1_armel.deb,
libz160-bin_11.09.01-1_armel.deb, .....
For update list, please refer package.txt.

B. For uboot parameter, please refer kernel command line:         
Kernel command line: console=ttymxc0,115200
video=mxcdi1fb:GBR24,XGA di0_primary tve
video=mxcdi0fb:RGB24,1024x768M@60
ip=dhcp root=/dev/mmcblk0p1 rw rootwait

C. We use imx driver i.MX5x Z160 for both display.
Please refer xorg.conf and Xorg.0.log.

D. RunΠes11ex to compare the 3D graphics performance
(a) For main display             
$ DISPLAY=:0.0 es11ex            
Press Enter to terminate...             
FPS: 82.64         
(b) For 2nd dispaly            
$ DISPLAY=:0.1 es11ex            
Press Enter to terminate...             
FPS: 11.43
