Raspberry Pi GPU Driver Turns Out To Be Crap

[ChrisXY]

I don't think there is another X driver ready yet. But at least two are in development. One requires quite some patches to the kernel with dma and stuff and is not released completely yet and another one tries to use glamor.

I don't think the glamor one would work on archlinux arm since it uses X.org 1.13 and as far as I know glamor doesn't work on 1.13 yet.

Hello,

Thanks taking time to anwser.
Those are indeed promising XFree driver, however I wonder how the various XBMC distribs manage the videos : using straight SDL ? or OpenGL without X ?
I have tried without success to compile this GL sample.
So far, I'm stuck with :

libEGL.so: undefined reference to `glxx_<whatever function>

Beside display, sound "sounds" like also an issue :

# modprobe snd_bcm2835
# alsaplayer

Nothing outputs to speakers throught the analog jack connection !

Not so bad, actually

I did port the GLES version of RollerCoaster here and programmed a Cube sample there, the GPU is doing fine till the code does not rely too much on the CPU.
