They were turned off over two years ago: https://bugs.chromium.org/p/chromium/issues/detail?id=392620
The bug to re-enable load_library_perftests and cc_perftests and media_perftests was marked fixed even though media_perftests were never re-enabled.

Prabhu tried to get them re-enabled, but he was confused. the tests are not telemetry tests, so he was talking to the wrong people: https://bugs.chromium.org/p/chromium/issues/detail?id=518964

I should be able to trivially re-enable them so long as they are in good working condition.

Thanks John for the help with the investigation!

I'm going to see if I can get the owner of crbug/392620 to re-enable them since he forgot to do that (I think). If I can't get him to do it then I will.

After we re-enable them, we may have to talk with the chromeperf dashboard folks (sullivan@'s team) to get "monitoring" turned back on for them. Then they will be on the dashboard again.

Thanks for digging in!

I re-enabled them, but I got an error, so I am going to revert my change.

Enable media_perftests on linux perfbot.

This required
1. Adding media_perftests to gn_isolate_map so that isolate can understand how
   to run them
2. Adding data dependencies to media_perftests target that are needed by the
   isolate script.
3. Added media_perftests to generate_perf_json.py configuration file.

A previous version of this CL (https://codereview.chromium.org/2595123002) got
reverted because I didn't do step 2. For that CL, I only tested media_perftests
in a local run. This time, I also ran using isolates as well. (Thanks eyaich@!)
See test run: https://chromium-swarm.appspot.com/task?id=3390ffce2596c810&refresh=10&request_detail=true&show_raw=1

Follow up CL(s) will also add support on Mac, Windows, and Android.

Okay, they are enabled for linux. Next I will enable them for Windows and Mac and Android.

Dale, do we need them enabled for CrOS? It is unclear how to do that, so I may need to reach out to Speed Infra team for help if we need CrOS.

It'd be nice, but Android && Linux are a good proxy if that's difficult.

 Issue 518964  has been merged into this issue.

Graphs work for linux: https://chromeperf.appspot.com/report?sid=6be379dd118ce33f527b87d069f31daa7e1acdb87972388e084d1b758337195c

Still haven't re-enabled for CrOS or Android. Will likely not do that work until next quarter still other things have priority.

*Still haven't _enabled_. I don't think these tests ever ran on Android or CrOS previously.

issue 709161 has progress for CrOS. Currently in research stage.

issue 714812 is related as well.

I'm marking this fixed. Remaining work is in separate bugs: 

Android:  issue 772179 
CrOS: issue 772181
