[directfb-users] NSC Geode display driver with FBDirect

Hi, Firstly thanks for DirectFB it's been very helpful.

I'm using the Geode framebuffer driver from Alex Pavloff's website
( and DirectFB with the NSC driver.

Everything works OK but the screen is drawn very slowly. Depending on
how complicated the screen is I get between 6 - 12 fps. If I disable HW
acceleration the the directfbrc file I get the same performance, so I'm
guessing my HW acceleration isn't working properly.

I get the following on stderr:

Dependent NSC Kernel FrameBuffer driver version is 2.7.7 or later
(*) DirectFB/GraphicsDevice: nsc NSC GX1/GX2 driver version 1.1 (NSC)
(*) DirectFB/Layer: Enabled 'FBDev Primary Layer'.
 (!!!)  *** CAUTION [setting new configuration failed] *** layers.c

Can anyone tell me the sort of performance I should be getting and have
any pointers as to the cause of my problems.

Thanks heaps, Michael McLellan
