Hi!
Hsin-Yi - can I work with you to get this work better understood? Either a
Vidyo/Hello meeting or IRC to talk through some details?
Hi Selena,
I was asked by various people the current status of emu-x86-kk porting;
hence I think it's great to post to dev-b2g, based on my limited
experience in emu porting, so that everybody knows where we are and how
far we are from the target. Thank you very much for the comments that
point out the necessary effort on in-tree configuration and to clarify
my misunderstanding. I have no idea who is working on b2g in-tree
configuration stuff right now, but I am willing to have a chat with you
first.
I haven't worked directly with B2G teams in the past -- I am the new manager
for the TaskCluster team, and work for Lawrence Mandel as a Technical Lead in
Release Engineering.
I mentioned this at Whistler: we need dedicated people inside B2G org to "own"
these in-tree configurations.
I wasn't at Whistler and not following this discussion. But I agree with
you that we ultimately need dedicated b2g in-tree config/build peers.
The TaskCluster team is available to train people on how to create task
definitions for build and test automation. We do not have enough staff to
manage greening up individual tests. This team is focused this quarter on
making the TaskCluster platform production ready for Firefox Desktop and
migrating off of BuildBot.
I've responded in detail below:

Stabilize TaskCluster. By monitoring Treeherder [1], it
looks that emu-ics tests on TC are not stable enough,
while results of the same tests are much greener on old
mechanism. Wondering if the failures result from
instability of TaskCluster. If so, we should fix the
instability first.
Fixing the tests requires a bunch of in-tree work. TaskCluster is designed so
that development teams can manage their own builds. All build configuration
will be moved in-tree for this purpose.
In looking at the builds that are failed, there appear to be configuration
errors in the task definitions:
https://tools.taskcluster.net/task-inspector/#d5ktZVx1Tc-0JguzfzdM5Q/
This is trying to execute a task with the command-line option
'--test-packages-url', but the necessary URL is not specified.
As I mentioned above, I can work with you on identifying the failures on each
build and helping identify fixes. If there are TaskCluster-specific failures,
we can address those. So far in my looking at the tasks, I've only seen in-tree
task definition errors.
Bug 1159091 - gecko:
Show emulator-x86-kk as it's own platform
This seems to be well underway.
Bug 1192118 - To
be able to enable tests per module on TackCluster
This request is for in-tree decision task changes, not a TaskCluster feature.
The in-tree stuff is just configuration, and chunking tests not something that
TaskCluster itself could do automatically. Someone has to rewrite that config
and/or the build itself.
Great to learn that and sorry for my misunderstanding. :)
Best regards,
Hsinyi

Thank you for assembling this!
I had a look through and, as I mentioned above, noticed that there's quite a
bit of bustage in-tree, that I think can be addressed if we work together.
