passing devmem as the system parameter produces the same result.
# dfbinfo --dfb:system=devmem

according to the output of the configure script I have compiled directfb
to support only devmemw

the following shows the fb devices are present.
# ls -l /dev/fb*
lrwxrwxrwx 1 root root 4 Jan 1 2000 /dev/fb0 -> fb/0
/dev/fb:
crw-rw---- 1 root root 29, 0 Jan 1 2000 0
would it make sense to try and reconfigure&build directfb to supprt
linuxfb?
I have also seen the flags --dfb:video-phys=0x83000000 and
--dfb:video-length=691200 used, but I don't know what they mean, or how
to determine the correct values.
Thanks,
