[Bug 31412] radeon memory leak
https://bugzilla.kernel.org/show_bug.cgi?id=31412 --- Comment #10 from Kevin kjs...@gmail.com 2011-03-20 20:40:04 --- echo 3 /proc/sys/vm/drop_caches cleared all of the memory. Thank you! See output below (ran after exiting X). I didn't try unloading the gpu stack. I can try it if you like. I also saved /proc/slabinfo before and after I dropped the caches. If I'm interpreting the file correctly, I only notice large drops in ext4 filesystem stuff. Is there a way to tell which slabs are considered buffers or cache? # free -m total used free sharedbuffers cached Mem: 5920 4318 1602 0113 2465 -/+ buffers/cache: 1740 4180 Swap: 7998 0 7998 # echo 3 /proc/sys/vm/drop_caches # free -m total used free sharedbuffers cached Mem: 5920225 5695 0 3 12 -/+ buffers/cache:209 5711 Swap: 7998 0 7998 -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel

It includes what Dave asked for.

https://bugzilla.kernel.org/show_bug.cgi?id=31412 --- Comment #9 from Dave Airlie airl...@linux.ie 2011-03-19 22:07:30 --- I'm having trouble reconciling this with the graphics driver. a) you claim it happens with fglrx as well, there is nothing shared between them (so it can't be a common gpu bug) b) nothing is leaking according to that debug info in anywhere obvious. One last test would be unload the gpu stack to see what happens got to runlevel 3 or anywhere X isn't rnunig echo 0 /sys/class/vtconsole/vtcon1/bind rmmod radeon ttm drm_kms_helper drm see if memory is still gone. maybe you can watch /proc/slabinfo to see where the memory might be going. It might also just be page cache from the pdf loading, does echo 3 /proc/sys/vm/drop_caches help? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel

Unless something we've done since is causing it or another race to happen. So logging out of X doesn't get the memory back? can you attach the contents of /sys/kernel/debug/dri/0/radeon_vram_mm and radeon_gtt_mm? (after mounting debugfs). -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel

https://bugzilla.kernel.org/show_bug.cgi?id=31412 --- Comment #4 from Kevin kjs...@gmail.com 2011-03-18 21:25:15 --- The problem occurred in 2.6.37 also. Logging out of X doesn't get the memory back. I'm also not sure if just scrolling a lot causes the problem. It seems to be easier for me to consume memory by opening many .pdf files.
