Hi,
I am writing a gfxdriver for Fujitsu mb86296 video card under DirectFB. When
I register layer in my driver, the example df_fire (
DirectFB-examples-1.0.0.tar.gz), there is no output in computer screen. the
error result looks like this:
sh-3.00# ./df_fire

my mb86296_layer.c refers to sh7722 gfxdriver and I don't understand some of
it since I don't have its munual. my mb86296_layer.c is as follows:

in driver_init_driver() , I called dfb_layers_register() to register three
layers since my video card support six layers.
/* Register three input system layers. */
sdrv->input1 = dfb_layers_register( sdrv->screen, driver_data,
&mb86296LayerFuncs );
sdrv->input2 = dfb_layers_register( sdrv->screen, driver_data,
&mb86296LayerFuncs );
sdrv->input3 = dfb_layers_register( sdrv->screen, driver_data,
&mb86296LayerFuncs );
I don't get what is wrong in my code. has anybody who has wriiten the
gfxdriver for the same video card help me out. Thanks in advance.
Sincerely yours,
liuxs
