Date: Tue, 9 May 2006 23:01:49 -0400 From: Mike Frysinger Subject: [SDL] [patch] fall back to using MAP_PRIVATE with mmap() in fbcon dri trying to use MAP_SHARED with mmap() on uClinux (aka non-mmu) hosts nowadays will simply fail since the kernel disallows it ... falling back to using MAP_PRIVATE on these hosts is acceptable ... as such, ive attached a patch for the fbcon driver that will fall back to using MAP_PRIVATE if mmap() with MAP_SHARED failed going by a grep of MAP_SHARED, the only other drivers that utilize this flag are video/wscons, video/ps2gs, and sound/dmaaudio ... i dont think these would appear on a non-mmu host so the patch i wrote is restricted to just SDL_fbvideo.c ... -mike
