Comment 1 Marta Löfstedt 2017-09-25 13:16:32 UTC

<marta_> Adrinael, you mentioned something about being wrong testlist for shards on CI_DRM_3026, could you elaborate. I have already filed bugs for this run...
<Adrinael> CI_DRM_3126
<Adrinael> It was running everything ever on accident
<Adrinael> ivyl, ^ right?
<marta_> but it was only 3 new drv_selftests and 3 new gem tests, for sure we have more than that blacklisted
<ivyl> yep, due to elaborated nature of deployment method, and streamilining it to use just "make install" an inevitable error occured on the human-Jenkins boundary.
<ivyl> marta_: it run with ALL ALL, but it got cancelled pretty quickly
<ivyl> and then rerun properly
<ivyl> what you see is the merge of both
<Adrinael> tools_test@* got "broken" by make install -deployment btw
* Weine (~dweineha@134.134.139.76) has joined
<ivyl> as jenkins haven't cleaned staging area for results
<Adrinael> marta_, if you file a bug on igt@tools_test@tools_test, make it an IGT bug
<ivyl> so sorry about confusion, it wasn't intended and I hoped the rerun will fix it
<ivyl> but as you can see we have the few leftovers
<marta_> OK, I will archive if needed when I results from the next run.
* Ahuj (Thunderbir@nat/intel/x-ngcmqbhsvahecvri) has joined
<ivyl> results from -27 already came in and they look clean, we also should have results for -28 in half an hour or so
<marta_> dolphin, disregard my comments on BUGS: 102970 and 102971 ^^. These test should not have been part of CI_DRM_3026, I will archive the bugs from cibuglog, but of course we will keep them in fdo.

Comment 2 Chris Wilson 2017-09-25 13:29:31 UTC

Nothing here indicts gem_busy.
