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 |~~~~~~~~~~~~~~~~~~~~~~~~~~ (c) 2001-2008 The world wide DirectFB Open Source Community (c) 2000-2004 Convergence (integrated media) GmbH ---------------------------------------------------------------- (*) DirectFB/Core: Single Application Core. (2008-08-20 16:19) (*) Davinci/Driver: Mapped fb0 with length 1658880 at 0x87800000 to 0x41193000 (*) Davinci/Driver: Mapped fb1 with length 2488320 at 0x87c00000 to 0x41328000 (*) Davinci/Driver: Mapped fb2 with length 442368 at 0x87e80000 to 0x41588000 (*) Davinci/Driver: Mapped fb3 with length 2488320 at 0x87400000 to 0x415f4000 (!) 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.
