1. ./gem_fence_upload
Comment 1 Daniel Vetter 2014-06-18 09:24:51 UTC 
This is a new testcase for a regression ... Can you please run the testcase from latest igt on older kernels to double-check whether it's not a regression?
Comment 2 Chris Wilson 2014-06-18 09:26:59 UTC 
It is not a regression, this just highlights the performance degradation due to fence contention.
Comment 3 Guo Jinxian 2014-06-19 08:36:42 UTC 
Test failed on BDW too.

Note the comment from Bug 97939 related to ./gem_fence_upload --r thread-contention
Chris Wilson 2016-10-05 09:35:31 UTC
This test is intended to fail as it is something that the driver cannot handle yet. The change is that we got faster at the baseline, but since the contention point itself is unchanged the highly contended cases are still slow, and so slower relative to the new baseline.

First of all. Sorry about spam.
This is mass update for our bugs. 

Sorry if you feel this annoying but with this trying to understand if bug still valid or not.
If bug investigation still in progress, please ignore this and I apologize!

If you think this is not anymore valid, please comment to the bug that can be closed.
If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug.
Comment 88 Elizabeth 2018-04-05 19:55:13 UTC 
This is still valid with the tests and in all the platforms:
