Bot(s) for this bug's original alert(s):

android-galaxy-s5
chromium-rel-win7-dual

+kbr: i am also getting this same error for smoothness.tough_webgl_cases on chromium-rel-win7 bot only (other Windows bots are fine). Same revision range 405221:405764.

Any ideas?

indicates that only the on-board Matrox GPU is being recognized on this machine.

Something's misconfigured on the machine.

Thanks, Ken! I filed bug 635723 on how we can detect this more easily in the future, can you please weigh in there if you have any ideas?

Vince, I'm assigning you this bug for triage. The GPU on build186-m1 is not being recognized, any ideas how to fix this?

That would be because this machine doesn't have a GPU. It's in a non-GPU rack.

Which GPU is needed?

Thanks, dba! I'm sorry I had this mixed up with the bots that do have GPUs. Assigning back to Justin, the test owner--it seems like it's expected that there's no data?

Ken, Justin, any idea if these tests may have gotten better at disabling themselves? They used to produce data on this machine, but the hardware has been the same for years.

I can only speak for smoothness.tough_webgl_cases, but that test's only supposed to run on the bots on https://build.chromium.org/p/chromium.perf/builders/ which have GPUs -- for example, the multiple "Win 7 Nvidia GPU Perf" bots.

I don't remember how the perf tests are assigned to bots and sharded among multiple bots. If that changed recently, that would explain why smoothness.tough_webgl_cases might have started spontaneously running on machines like https://build.chromium.org/p/chromium.perf/builders/Win%207%20Perf%20%282%29 , which apparently don't have GPUs. I can't explain why the test might have previously been passing on this machine.

I think it's okay to close this as WontFix since we're not actually getting data from bots without GPUs. I'm still not quite sure how we ever got data, though.
