I'm trying to understand how user space can efficiently manipulate physical memory, and I'm sure that X11 does that great. So this is just a learning exercise for me about X11.. I know that it can be done via: 1. mmap'ing /dev/mem 2. creating a char device driver that allocates physical memory and expose it via mmap() support and now i understand it can also be done via sysfs ? can you please comment on that and maybe tell what's the best way ? thank you for helping! > _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
