Hello everybody,
I would like to use DirectFB in the future on a PowerPC, running Linux,
without video card or any input, with virtual framebuffer.
Now for debugging I'm trying with Ubuntu on my Oracle VirtualBox with video
card, but I have some problem with configuring it. For debugging I try to
use devmem () to access the memory.
After installation I try to configure it in directfbrc with (even I don't
know what sould I use for video-phys and length, I saw these values in
forum):
system=devmem
no-hardware
software
no-mmx
video-phys=0x83000000
video-length=691200
no-debug
With fbset-i I get:
mode "640x480-60"
# D: 25.176 MHz, H: 31.469 kHz, V: 59.942 Hz
geometry 640 480 640 480 4
timings 39721 48 16 33 10 96 2
rgba 6/0,6/0,6/0,0/0
endmode
Frame buffer device information:
Name : VGA16 VGA
Address : 0xa0000
Size : 65536
Type : VGA 16 colors in 4 planes
Visual : PSEUDOCOLOR
XPanStep : 8
YPanStep : 1
YWrapStep : 0
LineLength : 80
Accelerator : No
When running dbinfo I get:

If I try it with FB instead of DEVMEM:

failed *** [call.c:526 in fusion_call_init()]
(!) [ 3999: 0.000] --> Caught signal 5 (unknown origin) <--

Please help me to go on with this project!
Thanks,
Gabor Halasz
