Hi The O2 fb driver (or something else) has broken mmap interface, you probably know that. Anyway, I've tried to find the cause for it but I've haven't been that succesfull. I've patched a current cvs kernel with the old O2-fb driver (from: http://www.linux-mips.org/~glaurung/)(before gbefb merge/rename) and mmap does not work with the old driver, so something else seem to have changed so that the mmap things don't work. The 2.6.1 kernel on the above page does have a functional mmap (my test app and X works with it) but it's very old.. Does anyone have any hints or ideas ? Oh, and I've added some sysfs stuff to the gbefb driver, should I post the changes here ? -- Kaj-Michael Lang , milang@xxxxxxx
