I have preprocessed code from nVidia, they released it last year.

I am currently working on the multi application core and can already run many applications on the same desktop sharing DirectFB. It's implemented via IPC, integrating it into the kernel would require way too much work and too much of DirectFB would have to be integrated. Besides that it's better to run with an unmodified kernel. > A kernel module is not a sin: > It would be easy to create (a i have tried yet). > Linux has web servers and a lot of other things in the kernel, i dont know > why it shouldn't handle graphics too!!! There are many people that don't want graphics support in the kernel, I also think that the kernel should only manage the device and give userspace the ability to use it. The kernel should be able to recover the device anytime, not more. For graphics cards this includes mode switching, that's why we have the Linux Framebuffer Device. > I have read in the site that the multiapplication core is at the end of > the todo section, while i think it should be at the beginning!!! I'm thinking the same and chose the multi app core as my current piece of work. > Even if it doesn't works well yet, let's make it usable first, then we'll > make it work!!!!!! I think the multi app core will be released as an alpha version in the next release, supposed to get out next week. -- Denis Oliver Kropp ( convergence ) ( integrated media gmbh ) -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
