Hello All,
Here is my problem :
I'm working on a TI DaVinci EVM 6446 board. My goal is to run DirectFB
(1.2.x) on this
board using the DaVinci GFX HW acceleration.
I use the kernel 2.6.25-davinci1
(http://source.mvista.com/git/?p=linux-davinci-2.6.git;a=summary) .
During the kernel configuration I enabled all the
items related to the DaVinci especially the FB support. Then I configure
DirectFB to support the gfxdriver=davinci.
When I run a DirectFB test, I've got those traces :
~~~~~~~~~~~~~~~~~~~~~~~~~~| DirectFB 1.2.3 |~~~~~~~~~~~~~~~~~~~~~~~~~~

(*) DirectFB/Core: Single Application Core. (2008-08-20 16:19)

(!) Direct/Util: opening '/dev/c64x' failed
--> No such device or address
(!!!) *** WARNING [running without DSP acceleration] ***
[davinci_gfxdriver.c:240 in
driver_init_driver()]
(*) DirectFB/Graphics: Texas Instruments Davinci 0.4 (Telio AG)
(*) DirectFB/Core/WM: Default 0.3 (directfb.org)
(!) Davinci/OSD: FBIO_SET_BITMAP_BLEND_FACTOR (fb0)!
--> Invalid argument
So it seems that I have 2 issues :
1. "Direct/Util: opening '/dev/c64x' failed". Do you have any idea about the
error ? What can I do to fix it ?
2.the ioctl "FBIO_SET_BITMAP_BLEND_FACTOR" is not defined in the DaVinci
kernel driver.
So it seems that the Davinci DirectFB driver and the kernel DaVinci driver
do not match.
Have you any idea about this issue ?
-> I'm surprised of this issues because according to directfb.org, DirectFB
seems to have already been running on DaVinci with gfx driver acceleration
on.
Any ideas or suggestions would be nice.
Thanx a lot for your help.
Julien
