Don
Attendees: Riku, Don, Glen, Matteo, Shebu, Anton, Joanna, Dave Rodgman
Minutes:
- TFC-20: Git performance - infrastructure changes happened including
Leonardo infrastructure changes. Tested on stage. Should keep an eye on it
for next few days. New machine already added back in. Better performance
will be seen as well since more jobs can focus on builds and not clones.
- Expect scripts: Should wrap up this week
- Joanna: Brought up LAVA timeouts TFC-176. Pass on 2nd or 3rd
attempts. Initial analysis is too many parallel LAVA jobs. Starting out by
increasing timeout. Would prevent re-running jobs.

timeouts

- Chromebooks still dealing w/ import issues.
- *ACTION: Don* ask Julius to reject and resend the 3 boards to the
Cambridge lab

agreed, begin the work.
- Glen: Meeting set up for tomorrow to discuss code coverage state and
how Arm might be able to help.
Hi Sherry,
I'm adding the triage maillist to the thread. As a best practice, let's cc
that list on items like this as it includes the stakeholders that
prioritize OpenCI tasks on a weekly basis(minimum) so it's helpful info in
that decision making.
I see you're already subscribed to the list which is great! :) Reviewing
the Aug 31st sync minutes, Expect scripts were determined to be the
priority. Code Coverage next steps are also discussed. Looks like Glen
was going to set up a sync meeting to further discuss this one... The
minutes could have called out this action more clearly:
- Code Coverage:
- A sync w/ Leonardo and Joanna to discuss next steps/Current status
on CC shall be planned. Glen to set up
> Is it suspended for pure priority reason, or any technical reason?
So with the above said, this is a prioritization decision made by the
triage stakeholders, not technical.
Hope this helps, please let me know if any questions or suggestions on
improving the process. :)
Best,
don

Hi Xinyu,
Thanks for the escalation.
I see Ben is in the loop, so that's the correct first step. I've also cc'd
the triage maillist to make sure all stakeholders are looped in.
In general, as a best practice, I would suggest having as much quantifiable
data as possible upfront in tickets like this to help better understand the
magnitude as well as how to reproduce. It looks like the tickets have
already started to capture this, but I also see Ben in the ticket
requesting more. Datapoints of interest in my mind:
- Clear details on how to reproduce: The task(s) where noticeable
degradation is seen - is this in parallel to when large builds have kicked
off? etc.
- Tasks invoked and level of degradation: for example, "Gerrit reviews -
previously took xyz seconds/minutes, now taking 20% more time (or 2x, 10x?,
failing & never completing?)," frequency, etc. The more details the
better! This will help determine the priority we place on resolving. :)
Perhaps coming up with a general template for this could be helpful.
- Is there other degradations beyond Gerrit?
Ben is most certainly much more qualified than me in knowing what support
is needed to isolate/resolve, and, as noted in the ticket, he is asking for
more details as well. Let's get the details captured in the ticket(s) in
preparation for next Tuesday's Triage meeting where we can prioritize the
resolution over other TFC tasks. :)
Ben, feel free to chime in and correct any of my assumptions/suggestions.
Regards,
Don

*Attendees*: Riku, Anton, Glen, Shebu, Ben C, Joanna, Janos, Matteo, Don,
Xinyu
*Minutes*:
- Glen: Begin w/ TFC Kanban Board
- Glen: H/W Status
- Working thru getting Chromebooks imported. In progress
- Cypress boards flashing and booting, starting on jobs work. In a
week ready for boards to be shipped to Cambridge.
- NXP board is in the queue.
- MBedTLS:
- Glen: Have advanced as far as can. Need AMI files from Dean A.
Blocked awaiting AMI files.
- Janos: Progressed since last week, but working on resolving
internal issues. No estimate yet from Dean.
- Glen: Plan to move to expect script efforts with team approval
- Matteo: Agree Expect Scripts are the next item to work. Would like
completed, so good direction to go.
- Code Coverage:
- A sync w/ Leonardo and Joanna to discuss next steps/Current status
on CC shall be planned. Glen to set up
- Glen: Performance/Fixes needed?
- Riku: Nightly jobs failing due to too many parallel checkouts of
same repo/same version. TFC-20. Need to decide how to implement
- For TF-M, looks currently like 1 week work to modify CI to reduce
parallel checkouts, TF-A still looking to get an estimate.
- Ben: TF-A may be a bit larger task, but still need to look.
- Ben: Other solutions?
- Glen: Could Arm TF-A / TF-M team do this to offload the work?
- Not currently
- Ben: Need a short-term and long-term solution. Short-term - added
a server, long-term, change the configuration changes.
- Can use Staging Server to test it out.
- Git checkout taking lots of the build time.
- Shebu: Failing every night?
- Not sure.
- Riku: Last week, 1 success all other failed.
- Ben: The new server increasing capacity has caused this issue to
show itself.
- Work around is to potentially limit the number of parallel jobs.
- Next Steps:
- Leonardo scope TF-A.
- Create two subtasks for TF-A and TF-M
- Riku: Put in work-around to limit number of parallel jobs
- Need a TFC ticket here?
