Accelerated graphics problem in imx53 and X11

Hi,

 

I'm trying to get accelerated graphics working in imx53 running Linux 2.6.35.3 and X11.

 

I got the imx_drv.so driver compiled and loaded. The problem is that while loading the driver the following error is printed to X11-log:

 

[ 99548.775] (EE) imx(0): Exclusive access for Z160 interface failed.

[ 99548.775] (II) imx(0): No acceleration in use

 

I've been trying to eliminate things that might use Z160, but can't seem to find any. Any idea what might be preventing Exclusive access of the Z160 interface?  I'll add the full Xorg.log to this post.

 

xorg.conf on display driver part is:

 

Section "Device"

    Identifier  "i.MX Accelerated Framebuffer Device"

    Driver      "imx"

    Option      "fbdev"     "/dev/fb0"

    Option      "FormatEPDC"    "Y8INV"

EndSection

 

Section "Monitor"

    Identifier  "Configured Monitor"

    Option          "DPMS"      "No"

EndSection

 

Section "Screen"

    Identifier  "Default Screen"

    Monitor     "Configured Monitor"

    Device      "i.MX Accelerated Framebuffer Device"

EndSection
