Bug Description
As far as we understand all firmware upgrades (and the firmware itself) is coming from the HMC on case of IBM Z and LinuxONE.
This not only incl. the CEC code, but also all the firmware for the different cards and adapters.
If this is the case (and will be in future), it would make sense for us to get rid of the linux-firmware package for s390x - this would make things leaner, reduce size and eventually increase (installation) performance ...
So please IBM can you confirm that all firmware updates (MCLs) are always done via the HMC and that is therefore the linux-firmware package is obsolete on s390x? Thx

Yes, all CEC, OSA, fibre channel cards will get their firmware via HMC. This is also true for the ROCE express cards.
The only thing that I do not know about is, are the NVMe cards that are provided by the customers. Not sure if we do support customer provides firmware updates for those.
But as far as I know this is extra tooling and not part of linux-firmware.
So yes, we should be able to avoid linux-firmware on s390.
(adding some people for double checking).
