Dear Daniel, many thanks, > You can have BDI_CAP_MAP_DIRECT for this architecture. > You just need to define HAVE_ARCH_FB_UNMAPPED_AREA and implement > get_fb_unmapped_area. Take a look at the Blackfin implementation > of this function. It might work without modification on m68k-nommu. > yes, should be quite easy to do as you mentioned, but requires minimal changes in the kernel, and i must keep the unofficial changes stored here locally with the current tree. Of course, i can send a patch to the list, but i am using kernel 2.6.x. and also not sure it can be useful to anyone except me, so easy to be unaccepted. For this reasons, my idea is to setup 2 or 3 ioctl's at driver level: - one to get memory address (direct memory map) - one to update all the screen - one to update a specific surface area What do you think is better ?
