http://bugs.freedesktop.org/show_bug.cgi?id=26521 Summary: Bug in kernel module - ttm_bo_pci_offset Product: xorg Version: 7.4 Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/nouveau AssignedTo: nouveau at lists.freedesktop.org

Just a gentle ping on this. Already got the Acked-by from Daniel, but I need some of the nouveau guys to test this since I can only compile test it. Regards, Christian.

While working on TTM cleanups I've found that the io_reserve_lru used by Nouveau is actually not working at all. In general we should remove driver specific handling from the memory management, so this patch moves the io_reserve_lru handling into Nouveau instead. The patch should be functional correct, but is only compile tested! Signed-off-by: Christian König <christian.koenig at

Hi guys, I've already send this out in September last year, but only got a response from Daniel. Could you guys please test this and tell me what you think about it? Basically I'm trying to remove all driver specific features from TTM which don't need to be inside the framework. Thanks, Christian.
