Created attachment 143800 [details] Video showing the 4 MB leak in 25 seconds It was found that the kernel 5.0 has a memory leak when Vulkan applications are used. It seems this leak can be even more intense than the one from bug 107899. On drm-tip and linux-git, the commit 61a98b1b9a8c7a21a2d666a090dcf5f1c70c659f fixes this leak. However, the leak is present on the kernel 5.0.5, currently the latest stable. vulkan-smoketest is enough to trigger the leak. On slabtop, it shows: 80275 80275 100% 0,62K 3211 25 51376K i915_request Steps to reproduce: 1) Open a Vulkan application, for example, vulkan-smoketest. System information: OS: Xubuntu 18.04; Kernel: 5.0.0-8 (Disco Dingo) to 5.0.5; CPU: Intel Core i3-6100U; GPU: Intel HD Graphics 520; Memory: 8 GB.
iirc the fix is commit 61a98b1b9a8c7a21a2d666a090dcf5f1c70c659f Author: Christian König <ckoenig.leichtzumerken@gmail.com> Date: Tue Dec 11 18:34:41 2018 +0800 drm/syncobj: remove drm_syncobj_cb and cleanup This completes "drm/syncobj: Drop add/remove_callback from driver interface" and cleans up the implementation a bit.

Fix available in drm-tip and 5.1-rc1 but not in stable branch 5.0.5.

Fixed upstream and not our bug. Move to DRM/other, assign to Christian to decide what to do with the potential stable backport.
Linux 5.0 is EOLed. Please use a supported kernel (see https://www.kernel.org/). Closing!
