FWIW, based on my trials: * DirectFB support on BE hosts is somehow easier than with carminefb: the patches from Nikita Egorov are working almost out of the box (they basically change every single access to memory so that it becomes ABGR, so that a simple memcpy to/from Carmine memory is already the right alignment. I don't know if it would be working without these patches on kernel >2.6.26 (with FOREIGN_ENDIAN defines) since I'm currently stuck to a vanilla 2.6.24.6 * However, DirectFB has some troubles with panning, which is working using a different approach by myself: I'll check it and see if it's worth posting here. * 800x600 resolution is supported if I try 800x600-24@60 before trying 640x480-16@60 Thank you, M Anatolij Gustschin ha scritto: > Matteo Fortini wrote: > > >> What about the mb86290 framebuffer driver directly from Fujitsu which is >> in the mainline kernel? >> > > This mb86290 framebuffer driver from Fujitsu isn't in mainline, it > is in the DENX Linux Kernel tree. > > >> It's from 2003 and supports only until 86293, but can it be used as a >> basis for a proper fb driver?
