Subject: [ELISA Development Process WG] Linux architecture

Hi,

A term that is frequently referenced in both the Development Process and
Safety Architecture working groups is 'architecture'.

This occasionally leads to misunderstandings because the term
'architecture' is used to refer to a number of different things in
different contexts: system architecture, component architecture, etc

John MacGregor has written a really useful document proposing a
definition of what we mean by the 'Linux architecture':

https://openjohnmacgregor.github.io/ElisaPages/LinuxArchitecture.html

I think it would be useful to discuss this document, to work out whether
John's proposal requires further refinement, and how it can inform our
various approaches and studies. For example, does this architecture need
to be extended to include other elements that are required to provide a
complete embedded OS based on the Linux kernel?

Would one of the working groups like to 'host' this in a regular
session, or should we schedule a separate Zoom call?

Yes I think we need to go over this document and more specifically we need to
follow up on this email thread
https://lists.elisa.tech/g/safety-architecture/topic/elisa_technical_community/82583176?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,82583176
to come to a common understanding.
Maybe the development process wg is a better forum to discuss this
but I don't mind to host this in the arch wg eventually.
@Elana what is your view on this?

Thanks
Gab

Regards,

Paul
