[Nouveau] [Bug 104340] New: Memory leak with GEM objects
https://bugs.freedesktop.org/show_bug.cgi?id=104340 Bug ID: 104340 Summary: Memory leak with GEM objects Product: xorg Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/nouveau Assignee: nouveau at lists.freedesktop.org Reporter: sgilles at math.umd.edu QA Contact: xorg-team at lists.x.org Created attachment 136291 --> https://bugs.freedesktop.org/attachment.cgi?id=136291&action=edit dmesg (up to last nouveau messages) I have a gk106, current versions of libdrm, mesa, kernel (observed both with -mainline and https://github.com/skeggsb/linux branch linux-4.15 as of a few minutes ago), and there appears to be a memory leak with nouveau that eats up about .5 GB every day. Killing X does nothing. Attached is output of dmesg from the most recent boot of this machine. I've also attached (in case it matters) dumps of /proc/meminfo and output of slabtop after I ran X for about two weeks, then exited and killed all major daemons. More importantly, I've attached a few hundred lines of /sys/kernel/debug/kmemleak (from the most recent boot). After the first few entries, they all start looking the same (except for the address and age). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=104340 --- Comment #4 from Ben Skeggs <skeggsb at gmail.com> --- I've pushed a fix for a rather stupid memory leak bug that's likely the cause of what you're seeing. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
