What is this "GitHub APP"?

Apps on GitHub are integrations with the GitHub APIs. This "GitHub APP" should be installed on repository and it will enable requests for arm-based runners . Sorry for not specifying this APP in the above comment. It is to avoid unnecessary access from public. The installation link will be provided, as well as document, after release.

So GitHub has no native Arm support?

Where it will run? Which servers?

> Sorry for not specifying this APP in the above comment.
> It is to avoid unnecessary access from public.

You want to control who can run on these servers?
There is no access control other than app installation?

> The installation link will be provided, as well as document, after release.

After release of the app? You mean it is not ready yet?

In current state of assumptions, it is a nack.

No, GitHub has no native Arm support.

Runners will run in AWS EC2 on Graviton2.

Whitelist mentioned in the comment is for access control, but we hope the link is not shared with anyone who has no repo get whitelisted.

The APP has been ready. It's waiting for a release date.

You mean the link is enough to run on your AWS instance?
There is no key control when running?
It looks really weak, and I don't want to merge anything in DPDK related
to some secret app.

Adding a new workflow should work on our 0-day-bot. We now support 
having multiple workflows so this looks good

I think I understand. I think you mean s/GitHub APP/GitHub/ . otherwise 
I dont know what that is. From my understanding you had to request 
special arm-based runners from github

Are DPDK/dpdk and ovsrobot/dpdk whitelisted to use the arm-based runners?

Maybe there was a thread about this in the past that I missed, but where 
and how do you get these arm-based runners from github?

GitHub APPs are integrations with the GitHub APIs and this one provided here will send requests for arm-based runners from AWS cloud. Document will be provided along with the APP to make better understanding after release. DPDK/dpdk and ovsrobot/dpdk are both whitelisted to use.
