description |
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 <jason@jlekstrand.net>

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.

== SRU Justification ==
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.
This commit has been cc'd to upstream stable, but it has not landed in
Bionic or Cosmic as of yet.
Details about the upstream bug can be seen at:

https://bugs.freedesktop.org/show_bug.cgi?id=107899
== Fix ==
337fe9f5c1e7 ("drm/syncobj: Don't leak fences when WAIT_FOR_SUBMIT is set")
== Regression Potential ==
Low. This commit has been cc'd to stable, so it has had additional
upstream review.
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
