Hi, >>I will try to write down the main points of my concern and then see how it will help you all to provide me with the required help.
>>1) Out Board had Linux Framebuffer, as STLinux is The Operating system for the hardware, So how can i really make the present DirectFB run on the board. If you have framebuffer device then you can port DirectFB by cross-compiling it for your target. On x86, the default frame buffer device is VESA, similary there will be something for your target depending upon your architecture,say XScale(ARM) or MIPS(AMD, Philips). You need to enable it and then use the cross-compiled DFB. 2) The second portion of the problem is How to write the hardware accelerated driver for the required board, and what all things that are to be considered for writing the driver. Again, this depends on the graphics card. The OS should have the framebuffer driver for that graphics card. After this, DirectFB should also have the chipset driver for this. If OS has the FB Driver for the card, and DFB doesn't then DFB chipset driver has to be written. If the OS itself doesn't have the FB Driver for that card, then that also needs to be written, meaning it will be something like device driver programming. Even if the card doen't driver in OS and/or DirectFB, you can always use the generic FB Driver(equivalent of VESA) for running DFB on your hardware, though it won't be HW Accelerated.

Hi, The help was great but the problem is that for my hardware the DirectFB is not ported. So i cannot do something like what is mentioned in the Link. >http://embeddedlinux.movial.fi/index.php?title=Port_Direct_FB#Writing_Dir ect_FB_driver I just wanted to know that in the DirectFB site it is written and i quote - Supported Hardware & Media Graphics Drivers If you have documentation about a card not supported by DirectFB but already has a framebuffer driver we encourage you to write an accelerated driver for DirectFB. Graphics drivers are located in the subdirectory "gfxdrivers" and will be built as modules. While there is no driver development guide the Matrox and the Voodoo driver give a good example. If you have to write a framebuffer driver because there is not one for that card yet, go for it! So How can i start writing these driver for the new board. I will try to write down the main points of my concern and then see how it will help you all to provide me with the required help. 1) Out Board had Linux Framebuffer, as STLinux is The Operating system for the hardware, So how can i really make the present DirectFB run on the board. 2) The second portion of the problem is How to write the hardware accelerated driver for the required board, and what all things that are to be considered for writing the driver. Please reply if i am not clear with my problem.
