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 ...

| 32 An SDL_QUITEVENT is generated when the user tries to close the application | |
| 33 window. If it is ignored or filtered out, the window will remain open. | |
| 34 If it is not ignored or filtered, it is queued normally and the window | |
| 35 is allowed to close. When the window is closed, screen updates will | |
| 36 complete, but have no effect. | |
| 37 | |
| 38 SDL_Init() installs signal handlers for SIGINT (keyboard interrupt) | |
| 39 and SIGTERM (system termination request), if handlers do not already | |
| 40 exist, that generate SDL_QUITEVENT events as well. There is no way | |
| 41 to determine the cause of an SDL_QUITEVENT, but setting a signal | |
| 42 handler in your application will override the default generation of | |
| 43 quit events for that signal. | |
