SDL support for Multi-layer vga-controller

SDL Development
1

Hi all,

I am searching for correct graphic library for my framebuffer device.
We have multi-layer (5 layers) framebuffer vga-controller, i.e. layer-0 for background,
layer-1 for video, layer-2 for text …

I have gone through some of the Documentation over SDL but none specifies these info.

Please help me with these questions (if you can ans any)

  1. Do we have any multi-layer handlling functionality in SDL ??

  2. Can SDL drive multiple framebuffers at a time over same fb-dev (if fb-device supports) ??

  3. I am trying to build SDL over Nios2 (No-MMU) platform, is there already done support for it or
    if I need to create one then approximatly what needed to be done for same ???

thanks in advance,

Cool, never heard of such a thing,
why are you using them ? Why does your apps need them ?

Hi Torsten,

Thanks for the interest and reply,

Actually I am not looking from app point of view, but from driver point of view.

why are you using them ?
I am using it because no other options are available for Nios board.
My vga chip supports layers so I thought why not select a graphic library which can handle layering (like directfb), if graphic library doesn’t supports layering then I have to implement handling of layers in framebuffer driver : )

Ok I can use only one layer and disable other, but my other question are still not answered !!!

Kindly help !!!

thanks
