[FEATURE] sof-test needs to support Fedora 34

[plbossart]

With the transition in Fedora34 from PulseAudio to Pipewire, some of our scripts dealing with PulseAudio need to be updated.

Adding Wim to the chain. @wtay

Could you link us to scripts which should be checked / modified?

[lgirdwood]

We have a lot of test scripts here https://github.com/thesofproject/sof-test/tree/master/test-case and IIIUC they all use the ALSA APIs (i.e. none use any PA APIs) so my expectation is that these should work (or require minimal configuration changes).

I think the largest task is probably to integrate the Jenkins based audio test infrastructure we have to additionally support RPM pagkages. Today, Debian based tooling is used to update kernels, modules and tooling on each DUT and we need to make sure we can support RPM here too on F34 and beyond.

@kv2019i @aiChaoSONG @marc-hb any further comments here ?

Agreed: 95% of sof-test should just work on Fedora (please report bugs and/or submit fixes) whereas the Debian packaging of the kernel and ALSA packages is obviously not going to work.

Custom ALSA packages are less often required on Fedora though :-) thesofproject/sof#2543

Installing dependencies is straightforward:

dnf install expect python3-graphviz python3-numpy python3-scipy

the rest is less clear:

Checking group memberships:		Warning
Solution:

	Missing permission to run command as sudo

		Please use the following command to add current user to the group sudo:

	 sudo usermod --append --groups sudo 

why is this needed?

	Missing /var/log/kern.log file, which is where we'll catch the kernel log

		Please create the link of your distribution kernel log file at /var/log/kern.log

I thought we are now using journalctl? What is this dependency, is it still needed?

[plbossart]

cut: /var/log/kern.log: No such file or directory

fantastic.

[marc-hb]

There are many commands in sof-test that need sudo, starting with inserting and removing modules.

I thought we are now using journalctl? What is this dependency, is it still needed?

It's unfortunately not complete, see internal issue 477 and others.

cut: /var/log/kern.log: No such file or directory [INFO] Test Result: PASS!

#312 should help, it has been implemented on some tests but not others. Does every test "PASS" like this?

The good news is: these are not new issues and not specific to Fedora. The bad news is: all this is down to prioritization. When everything is urgent, nothing is.

@plbossart check this ongoing PR, it totally removes /var/log/kern.log, and use journalctl.

Edit: PR #639, @marc-hb thanks.

cut: /var/log/kern.log: No such file or directory

Unfortunately, only Ubuntu use this file

[marc-hb]

I guess @aiChaoSONG is referring to #639

[mengdonglin]

PR #639 was separated to two other PRs #643, #649 that were merged. So sof-test is ready. The remaining work is remove usage of sudo group but to use audio group for all OSes. Close this issue.
