Hi all,
Geexbox 3 is a great work, thanks a lot for the good work.
I wanted some information that would really help me a lot, I am working on pandaboard.
I saw in you geexbox 3, while running xbmc the frames per second is really good (58fps) it is using hardware acceleration.
Well I have built the linaro kernel version with ubuntu file system, on that I am trying to install graphics drivers, got from the http://git.linaro.org/gitweb?p=people/rsalveti/pvr-omap4.git;a=summary. I have build the drivers from cross compoler arm-linux-gnueabi- which was used to build the kernel. I got an omapdrm_pvr.ko file.
I copied the omapdrm_pvr.ko and usr folder to the filesystem.
After installing the module, lsmod shows omapdrm_pvr.ko running :)
But when I install and run XBMC it is very slow, on the hardware info I can see that the frames per second is just 0.29 :(.
In the GPU it shows SOFTWARE RASTERIZEER. I know this is the problem..
Please can any one show light to solve this. So that my xbmc uses the GPU hardware...
Any help highly appreciated

You need to use the same kernel and cross toolchain other module won't load up.

@benjamin thanks a lot for th replay.
I am using the same kernel and cross compiler. I am using linaro kernel version 3.4 and pvr module from http://git.linaro.org/gitweb?p=people/rsalveti/pvr-omap4.git;a=summary . Both built using the same cross compiler arm-linux-gnueabi- .
When i do lsmod it shows omapdrm_pvr ,
But when I run xbmc it is not using the GPU hardware, it shows it is using software rasterizer.

I used my linux kernel linaro 3.4.11 ( along with the modules) with the geexbox file system than pvr is working fine.
So this means that there is something i need to do in my filesystem so the pvr graphics driver must work.
Please can any one say me what all I need to install for working PVR drivers also OpenGL . I have opamdrm_pvr module running .
What extra must be installed .
Any help is highly appreciated
