[Openchrome-users] Different confs for different chipsets

[Xavier Bachelot]

Hi,

I promised to start a 'tips and tricks' page some monthes ago, with the
usual confs for different unichrome chipsets to get good
results/performances. Here is what I gathered, brain-dump style, not
really sorted.

Basically, there are 2 options that really matter in xorg.conf,
enableAGPDMA and DisableIRQ. There are also 2 options that matter for
xine, unichrome_cpu_save and xvmc_more_frames.

Format all that in a table ? Link it from the 'hardware caveats' page or
extend this page ? Sort stuff by chipset or by option ?

CLE266 :
xorg.conf : Option 'enableAGPDMA'
xine : video.device.unichrome_cpu_save:0
xine : video.device.xvmc_more_frames:1
misc : max XvMC size : 1024*1024

KM400 :
xorg.conf : Option 'DisableIRQ'
xorg.conf : Option 'enableAGPDMA'
xine : video.device.unichrome_cpu_save:0
misc : XvMC not supported on this chipset

KM40OA :
xorg.conf : Option 'enableAGPDMA'
xine : video.device.unichrome_cpu_save:0
misc : XvMC not supported on this chipset

K8M800 :
xorg.conf : Option 'enableAGPDMA' '0'
xorg.conf : Option 'DisableIRQ'
xine : video.device.unichrome_cpu_save:1
--> requires that the kernel timer tick frequency is 1000Hz or above
misc :

CN400 :
xorg.conf : Option 'enableAGPDMA'
xine : unichrome_cpu_save:0

VN800 :


CN700 :
xorg.conf : Option 'enableAGPDMA' '0'
xine : unichrome_cpu_save:1
--> requires that the kernel timer tick frequency is 1000Hz or above


If ppl feel like sending comments or additional infos or whatever before
I start to throw all that in the wiki, it would be nice ;-)

Regards,

Xavier
