Public bug reported: Vulkan applications, as Dota 2 and DXVK games cause a memory leak where memory is never freed and can cause a system crash if the applications are used for long enough. Certain applications can make the leak be as high as 10 MB/minute.
Details about this bug can be seen at https://github.com/doitsujin/dxvk/issues/632 and https://bugs.freedesktop.org/show_bug.cgi?id=107899 This bug was fixed in 4.19-rc6 and was backported to 4.14 and 4.18. The particular commit is: commit a2cef7d049f07995406b403605119a54881daf15 Author: Jason Ekstrand <ja...@jlekstrand.net> Date: Wed Sep 26 02:17:03 2018 -0500 drm/syncobj: Don't leak fences when WAIT_FOR_SUBMIT is set commit 337fe9f5c1e7de1f391c6a692531379d2aa2ee11 upstream. We attempt to get fences earlier in the hopes that everything will already have fences and no callbacks will be needed. If we do succeed in getting a fence, getting one a second time will result in a duplicate ref with no unref. This is causing memory leaks in Vulkan applications that create a lot of fences; playing for a few hours can, apparently, bring down the system.
