The failing tests are disabled on Linux Intel.

Yunchao, can I assign it to you to take a look?  It's really weird these tests will time out.  Assuming you have a Linux Intel HD 530 in house.

@zmo, I am not sure whether we have a Intel HD 530 at hand. I can own this bug if we have such a device to reproduce the issue.

Yang, can you get Intel HD 530 on your side for both Windows / Linux?  So your machines and the chromium waterfall bots can be aligned.

We have all the machines for GEN8 and GEN9 in house on Linux, Windows and MacOS. For Linux and Windows, we happen to have exactly the same HD 530. 
For this issue, Qiankun already investigated and this case failed due to long link time of large shader in Mesa. We will follow up with Mesa team. 
Let me change the owner to Qiankun.

Issue 680618 has been merged into this issue.

The assigned owner "qiankun.miao@intel.com" is not able to receive e-mails, please re-triage.

The link time of the GLSL tests on Intel HD 530 decreased if we update mesa to 17.0.0 which is released in February 13, 2017(https://www.mesa3d.org/).The link time costs about 4097ms with mesa 17.0.0 incomparision to previous version, mesa 11.2.2 costs 140032 ms.

That's great news!

How do we conveniently upgrade our machines to pick up this version of Mesa? Is there an Ubuntu package available for it?

You can update Ubuntu to 17.04, the Mesa version will upgrade to 17.03 simultaneously.

OK, thanks for the info. Filed a request with our Labs team to upgrade these machines to Ubuntu 17.04 if possible.

Again, if there's just an Ubuntu package which can be installed on 16.10 (which is what these machines are currently running) that would probably be easier. They're currently running Mesa 13.0.2; see:

https://luci-logdog.appspot.com/v/?s=chromium%2Fbb%2Fchromium.gpu.fyi%2FLinux_Release__Intel_HD_530_%2F782%2F%2B%2Frecipes%2Fsteps%2Fgpu_process_launch_tests%2F0%2Fstdout

Intel graphics update tool for linux published by Intel official only support mesa 13.0.2 on ubuntu 16.10 till now(https://01.org/linuxgraphics/downloads/intel-graphics-update-tool-linux-os-v2.0.4).  You could build mesa source code and apply it by LD_LIBRARY_PATH to use mesa library in the run-time(https://www.mesa3d.org/download.html). 

Once the HD 530 machines have been removed from the waterfall in Issue 754857, these tests should be able to be re-enabled on Intel (on the HD 630 bots that were recently added).

The Intel HD 530 bots have been removed. The new Intel HD 630 bot is running Mesa 17.0.3:

https://luci-milo.appspot.com/buildbot/chromium.gpu.fyi/Linux%20Release%20%28Intel%20HD%20630%29/

Could someone please re-enable the previously disabled gl_tests on Intel GPUs? Thanks.

Clean up end2end tests for Intel Linux platform.

Removed tests can pass on Intel Linux Desktop (Intel KabyLake, Ubuntu 17.04)
with system default mesa and latest upstream mesa.
