Xen FuSa meeting minutes Jan 25

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxx>]

Hi all,

These are the notes from today's meeting.

Apologies for the "meeting ID is invalid" errors when joining the
meeting. We are choosing a different slot for the meeting anyway -- I'll
send a new invite for the next meeting and the error will go away also.

Cheers,

Stefano



# Conferences

A 2-hours session to discuss the MISRA-C code style in details with the
maintainers at the next Xen Summit.

Submitting a presentation to the next Elisa workshop in April.


# FuSa meeting

Stefano to send a Doodle poll to find another slot for the call.


# MISRA

Bertrand is about to send the cppcheck patch to xen-devel. We are
waiting for an answer from David Ward about the MISRA-C copyright text.

We could start by sending a cppcheck patch that only checks for cppcheck
issues (not MISRA-C issues). This is a good way to start for a couple of
reasons:
- we want to start by fixing cppcheck issues (not MISRA-C issues) anyway
- it reduces to total number of issues reported which makes the output
  easier to read and understand


# RCU

The RCU subsystem is not useful today on ARM and it doesn't work when
using sched=null vwfi=native. We have fixes but not committed yet.
Should we remove the RCU (with a kconfig) on ARM instead? If the RCU is
not useful to Xen in general, we could maybe change it to something
else.

Next step: understand why the RCU subsystem is useful today to x86.


# CI loop

We should add a cppcheck test to gitlab-ci. We could start by making the
test fail if new issues are reported of types we currently don't have
any reported issues for.

We also need a real-time test. Stefano has a real-time test, but where
to run it? Gitlab-ci only runs tests in emulators, we need to run this
on real hardware.

Do we need to add real hardware tests to gitlab-ci?
