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@tal.org From mboxrd@z Thu Jan 1 00:00:00 1970 Received: from fairytale.tal.org (cruel.tal.org [195.16.220.85]) by gw02.mail.saunalahti.fi (Postfix) with ESMTP id 5CE29177E8 for ; Mon, 16 Aug 2004 20:43:26 +0300 (EEST) Received: from amos (unknown [195.16.220.84]) by fairytale.tal.org (Postfix) with SMTP id 6AF428DB0 for ; Mon, 16 Aug 2004 20:51:57 +0300 (EEST) Message-ID: <001501c483b9$36dc6b60$54dc10c3@amos> From: "Kaj-Michael Lang" Subject: O2 framebuffer and mmap..
