Subject: Re: KernelCI switch to new testing architecture - plan

Hello everyone,

It is for another update on the switch to the new testing architecture. 
As already highlighted in the previous
  email,we keep enabling new trees and tests, and enabling labs in the 
system. The new Web Dashboard is
  also under fast development, through a specialized supplier company 
hired by the KernelCI Foundation
  and a first beta version is expected by LPC.

We are also going through a major overhaul of the KernelCI project 
documentation to highlight the
  different ways different users can engage with KernelCI. For example: 
upstream kernel maintainers
  are interested in adding tests, Lab owners are interested in adding 
the labs, CI systems across the
  Linux community are interested in sending their data to KCIDB. It will 
take some time for all
  documentation changes to land, so hold tight and send an email to us 
at kernelci@...ts.linux.dev
  if you have any questions.

As for shutting down our legacy system, in the coming days both the 
BayLibre and Collabora
  will be disconnected from the legacy system, removing a significant 
amount of devices. The
  message is pretty clear: no one should be using legacy KernelCI anymore.

**If you are depending on legacy KernelCI, please speak up, so we can 
help you move your
  stuff over to the new system.**

## What is legacy KernelCI?

It is the old Jenkins based system with results showing up at 
linux.kernelci.org - if you are still
  using it you are using legacy KernelCI


## Where is the dashboard for the new KernelCI?

As highlighted in the beginning of this message, the new dashboard is 
under fast development
  after a good phase of UX research. In the meantime, we created a 
grafana dashboard that we
  will deploy in the coming days and share the link here.

Let me know any other questions you have. We'd be happy to answer them.

Best regards,

- Gus
