Hello all,

I've tried 2 git versions of davinci kernel.
One from Arago project
(git://arago-project.org/git/projects/linux-davinci.git),
Another from Khilman
(git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-davinci.git)
but both of them fails on fb.

there're /dev/fb[0-3] files, and DirectFB apps runs great.

# dmesg | grep davincifb
davincifb davincifb: dm_osd0_fb: 720x480x16@0,0 with framebuffer size 675KB
davincifb davincifb: dm_vid0_fb: 0x0x16@0,0 with framebuffer size 1020KB
davincifb davincifb: dm_osd1_fb: 720x480x4@0,0 with framebuffer size 675KB
davincifb davincifb: dm_vid1_fb: 0x0x16@0,0 with framebuffer size 1020KB
davincifb davincifb.0: dm_osd0_fb: Failed to obtain ownership of OSD window.

# lite_simple
~~~~~~~~~~~~~~~~~~~~~| DirectFB 1.4.2 |~~~~~~~~~~~~~~~~~~~~~
...
(*) DirectFB/Core: Single Application Core. (2009-11-06 06:50)
...
(*) DirectFB/FBDev: Found 'dm_osd0_fb' (ID 0) with frame buffer at
0x86100000, 675k (MMIO 0x00000000, 0k)

*BUT THERE'S NO OUTPUT ON SCREEN!!!*
there's no output from neither DAC A/B/C/D nor S-Video out jack, the
screen rendered black and there's no little penguin picture on the
top-left corner on boot.

I'm sure i've enabled CONFIG_FB_DAVINCI=y in kernel .config.

TI decode demo fails at FBIO_WAITFORVSYNC (CE_DEBUG=1 told me that).

With 2.6.26-davinci1 there's output on screen (I changed nothing but the
kernel) but there's other problem with 2.6.26-davinci1.

tkx for the help!
