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

chromium-rel-win7-gpu-intel

kbr, zmo: this is the commit range where the test started being skipped:
https://chromium.googlesource.com/chromium/src/+log/5ec1c6df6c10a2eb6911dcf6aa01b5ffcfe6eabe%5E..de6e057645ab4d0085bcd65f69463b6e6b0d0c04?pretty=fuller

I think CanRunOnBrowser here became false:
https://cs.chromium.org/chromium/src/tools/perf/page_sets/webgl_supported_shared_state.py?type=cs&q=CanRunOnBrowser&l=9

Could it have been one of the angle rolls?

Argh. Is it possible to get a narrower regression range?

CC'ing Geoff and Jamie.

Was there any other out-of-band upgrade to this bot (hardware update, driver update)?

Can we find the host names for the machines running these tests, or find any kind of failure log for them? I don't know where to look.

The drivers for some Intel bots were ugpraded in issue 680708 and the hosts were 

build164-m1
build165-m1
build166-m1
build167-m1
build168-m1
build183-m1

Re #5: Yes, these tests are running on the machines with upgraded drivers (build164-m1, build165-m1, build166-m1, build167-m1, build168-m1, build183-m1) and the date overlaps with the upgrade of the drivers (for the non-bisect slaves) in the bug. So I think this started happening with the driver upgrade.

Jamie, Ken, based on #6 should the driver upgrade be rolled back?

I don't really understand what's going on here. I don't think the driver should be rolled back.

Please do not roll back the driver upgrade. The new driver is being run on other machines that are running WebGL tests just fine. Again, we need to debug into this and figure out what is going wrong on these machines. Could someone please provide links to the machines on which the tests are failing? https://build.chromium.org/p/chromium.perf is currently returning 503 "Service Temporarily Unavailable".

To get the logs:

1) I use luci-milo.appspot.com when buildbot ui is down:
https://luci-milo.appspot.com/buildbot/chromium.perf/Win%207%20Intel%20GPU%20Perf/
https://luci-milo.appspot.com/buildbot/chromium.perf/Win%207%20Intel%20GPU%20Perf/485

2) Then I clicked the "cached" link next to stdio for logdog logs:

Thanks very much Annie for the links. Something looks badly misconfigured on this machine. These portions of the log:

mean that the GPU on this machine isn't being detected at all, even by a PCI bus scan. I can't guess how this is possible.

Our team has an Intel GPU bot deployed here:
https://build.chromium.org/p/chromium.gpu.fyi/builders/Win10%20Release%20%28Intel%20HD%20530%29

and it's working fine. Here's a similar log excerpt from that machine:

Who can administer these Windows machines with Intel GPUs that are in the Swarming pool and see what the desktop UI thinks about their state? Vince, could you find someone from the Labs team to help? build165-m1 and build166-m1 are a couple of machine that ran webgl-related tests in this job:

https://luci-milo.appspot.com/buildbot/chromium.perf/Win%207%20Intel%20GPU%20Perf/487

e.g.:

https://chromium-swarm.appspot.com/task?id=34bed84451149e10&refresh=10&show_raw=1

Thanks.

The intel gpu slaves in the chrome-perf swarming pool are build{164..168}-m1 and are the xeon based cpus with the embedded p4600 graphics.

I connected to all the consoles and only build164-m1 is displaying any video.
Looking at a sample task on build164-m1 ( https://chromium-swarm.appspot.com/task?id=34c1a6e6826a5610&refresh=10&show_raw=1 )

Will look at build{165..168}-m1

Power cycled them and the console display came back.

Looking at this shard that was run on build166-m1 it now runs the test

https://chromium-swarm.appspot.com/task?id=34c1a7587a1bbd10&refresh=10&show_raw=1

Not sure what to do about this.  They are running bios version 03.03.0002
The latest is 03.03.0006 but the release notes don't mention anything wrt to what the cpu microcode updates fix.

Long term it may make sense to migrate the Perf Intel slaves to the same platform that the gpu folks are using?   

btw might as well add build183-m1 to the chrome-perf pool.  It's available for use.

It's not my decision to make, but I would support switching the Win Intel Perf slaves to the same platform as these Intel HD 530 machines:

https://build.chromium.org/p/chromium.gpu.fyi/builders/Win10%20Debug%20(Intel%20HD%20530)
https://build.chromium.org/p/chromium.gpu.fyi/builders/Win10%20Release%20%28Intel%20HD%20530%29

These machines have been reliable since they were put on the waterfall.

If Annie agrees, then maybe we could put several of these slaves into the Chrome Perf Swarming pool.

+benhenry WDYT about using the hardware GPU team has found to be reliable as suggested in #14?

 Issue 737679  has been merged into this issue.

Can we put a couple on our FYI to see how they perform? We'd just need 1 to start (right?) with the option to order more for the main and tryserver (bisect) waterfalls

Note: at this point, pschmidt@ has been helping us deploy the revised version of this hardware:
https://luci-milo.appspot.com/buildbot/chromium.gpu.fyi/Win10%20Release%20%28Intel%20HD%20630%29/
