gpu_rasterization_tests: GpuRasterization.BlueBox flaky on new Win/AMD hardware

Project Member Reported by jmad...@chromium.org, Oct 6 2016

Issue description

Started failing here:

https://build.chromium.org/p/chromium.gpu.fyi/builders/Win7%20Release%20%28ATI%29/builds/24070

Several other flaky builds:
https://build.chromium.org/p/chromium.gpu.fyi/builders/Win7%20Debug%20%28ATI%29/builds/6143
https://build.chromium.org/p/chromium.gpu.fyi/builders/Win7%20Release%20%28ATI%29/builds/24084

https://build.chromium.org/p/tryserver.chromium.angle/builders/win_angle_rel_ng/builds/2427

Unsure if this affects only the new hardware/drivers.

Mark GpuRasterization.BlueBox flaky on new Win/AMD drivers.

This test seems to have started flaking since the change to new AMD.
It looks as though it had been flaking before we switched the swarming
pool to the new cards.

Blockedon: 491419
Thanks for finding and suppressing the flaky failure Jamie. Unfortunately it looks like the longstanding D3D driver problem which affects ANGLE's glReadPixels implementation still isn't fixed.

Comment 4 by kbr@chromium.org, Oct 7 2016

Blockedon: -491419
Status: Available (was: Unconfirmed)
Jamie pointed out in a separate thread that these tests were reliable on the older AMD GPUs that were just replaced, so it's unlikely to be the same bug.

Additionally, I'd forgotten that these tests read back their pixel results in a completely different way than the WebGL conformance tests.

It seems likely there's a bug in GPU rasterization on this AMD hardware. The symptom looks like the CSS 3D-transformed div is occasionally not being rendered. Someone should try to reproduce this locally on similar hardware:

./content/test/gpu/run_gpu_test.py gpu_rasterization --story-filter=GpuRasterization.BlueBox --pageset-repeat=100 --max-failures=1

Labels: Hotlist-PixelWrangler
My suppression didn't seem to do the trick, test is still failing:

https://build.chromium.org/p/chromium.gpu.fyi/builders/Win7%20Release%20%28ATI%29/builds/24135

Can someone take a look at this next week? I'll be out for a while.

Thanks for trying. I'll take it.

I wonder if  Issue 546575  could be related.
Gpu Rasterization actually appears really broken with latest AMD drivers in general. I'm guessing this is causing the flakes (the test flakes for me with this change, but a lot of other things are wrong as well).

I'm getting black bars all over chrome. I wasn't seeing this with previous drivers (had to update).

I'm currently on AMD Radeon version 16.9.2 on an AMD E2-7110 APU

Given that I have a machine that repros this, I'm happy to investigate.

Wow. That looks pretty bad. That's surely the cause of the test failure.

Thanks Eric for agreeing to take this. Let me assign it to you. A revised suppression for the failing test is in the CQ in https://codereview.chromium.org/2400373002 , btw.

Please tell me if you'd like me to put you in touch with our contacts at AMD if you triage this to a driver bug (almost surely, given the regression).

So, from what I can tell this issue persists pretty far back (checked a Jan. build) with Gpu Raster enabled.

Additionally, I tried capturing a trace with Visual Studio, but the issue disappears while capturing frames in VS. This makes me suspect that we're dealing with a synchronization issue.
Adding additional glFinishes around potentially problematic sync points doesn't help things, but using D3D9 Angle does fix this, so likely a D3D11 issue.

Comment 13 by kbr@chromium.org, Oct 11 2016

That's quite disconcerting. Please talk directly with geofflang@ tomorrow about this.

Cc: geoffl...@chromium.org
Discussed with geofflang@, he will look into this tomorrow.

I was able to capture a trace which shows the error. You can find it attached (capture.vsglog).

The trace can be played back using DXCap.exe on windows. If played back with an ATI card on latest drivers, the final frame will include blue in it (see screenshot_1). If played back with WARP, the screenshot shows the correct pixels (screenshot_2).

To play this back locally you can run:
DXCap.exe -p capture.vsglog
or
DSCap.exe -p capture.vsglog -warp

The fact that this DX playback is different on WARP/Driver almost certainly indicates a driver bug. We should forward this trace along to someone at AMD.

The capture can also be opened in Visual Studio, which allows you to browse through all the DX commands that generated the frame. Note that when debugging under VS you won't see the error visually.

Comment 15 by kbr@chromium.org, Oct 12 2016

Excellent work Eric. Bonus points for using a cute cat picture in the test case.

Fyi - the issue seems to have appeared in the 16.7.3 driver - 16.7.2 doesn't show the bug, but 16.7.3+ does.
Dug into this a bit today but not many results.

It appears draw calls or texture data are getting corrupted on this driver but it's hard to narrow it down to where the corruption first happens because all the playback tools use software emulation.

AMD PerfStudio and RenderDoc also don't seem to be able to capture anything despite being able to connect to Chrome.

I think the next action is to forward the capture file to AMD as it is almost certainly a driver bug.

Comment 20 by kbr@chromium.org, Oct 22 2016

Status: ExternalDependency (was: Assigned)
Marking ExternalDependency until a driver's been released fixing this issue.

If "GPU rasterization has been disabled on this configuration", why does it fail here:
https://build.chromium.org/p/tryserver.chromium.angle/builders/win_angle_rel_ng/builds/2567?
Do the tests enable GPU rasterization via flags? I believe that still overrides the blacklist - maybe we still need the suppression.
Yes, I see "--force-gpu-rasterization" in the log. Will revert https://chromiumcodereview.appspot.com/2442963002 then.
Oh, you already did that. Thanks!

Revert of Remove GpuRasterization.BlueBox suppression for Win/AMD. (patchset #1 id:1 of https://chromiumcodereview.appspot.com/2442963002/ )

Reason for revert:
Looks like the tests use --force-gpu-rasterization, which overrides the blacklist. I think we still need this suppression.

I see it failed 3 retries here:
https://build.chromium.org/p/chromium.gpu.fyi/builders/Win7%20Debug%20%28AMD%29/builds/173
Though, I don't see any logs related to retrying other than
FLAKY TEST FAILURE, retrying: GpuRasterization.BlueBox
FLAKY TEST FAILURE, retrying: GpuRasterization.BlueBox
So, maybe the harness doesn't really flaky tests.
It seems possible the flaky handling in the harness isn't working properly.

Comment 39 by kbr@chromium.org, Dec 1 2016

gpu_rasterization_tests desperately needs to be ported to the gpu_integration_test harness, similarly to how pixel_test was in  Issue 352807 . This will fix any issues with broken retries. If you have any time to help with that I'd greatly appreciate it.

Comment 40 by acci...@gmail.com, Dec 12 2016

The new driver version 16.12.1 released 12/8/16 fixes these issues.

The blacklist has been updated to allow GPU rasterization on drivers which contain the fix.

I've opened a new bug to track updating the gpu_rasterization_tests to the gpu_integration_test_harness (comment #39).
Brand new Radeon RX 480, Radeon Software Version 16.12.2, still seeing black boxes in chrome. Specifically in google sheets when editing cells, and on soundcloud. Looks like rasterization is enabled, although I don't know how to read the GPU page on chrome. I've completely reinstalled both the drivers and chrome.

This seems to be fixed on RX 480 with Radeon Software Version 17.2.1. I tested all of my usual tabs, as well as the Pangolin Love Google Doodle, which I assume to be raster dependent to some degree. Not sure if it matters that I'm on Windows 10 with the Anniversary Update.

I also verified that the DXCap capture log above ends like the WARP screen shot, not with any blue corruption, first before I attempted to test rasterization in the browser, worried that I may render the flags page unusable due to glitches.

kbr@, do you know if we have plans to upgrade our drivers to the new 17.3.1 driver? I think the only thing left to do here is to re-enable the test once a driver update has happened.

I remember we tried to update to 16.12.1, but hit a number of issues.

eric: I just filed Issue 702393 about upgrading the sole non-Swarmed Windows AMD bot to the latest driver. If that one's upgraded and it looks good then we can try upgrading the machines in the Swarming pool.

It's a fair amount of work to do the driver update completely safely -- see https://www.chromium.org/developers/testing/gpu-testing/gpu-bot-details#TOC-How-to-test-and-deploy-a-driver-update . If you or someone else would like to drive that process, I'll gladly support you. Otherwise we'll take the risk of upgrading the machines in the Swarming pool without first putting that exact hardware and device driver configuration on the waterfall.
