Enhanced Hardware Support - Finalize Naming

This feature request will provide the final naming of the next machine

Marking as "Incomplete" while awaiting the final naming.

@IBM: Does it affect the kernel only, or also other packages (like for example qemu) ?

And btw. I think it will not be limited to eoan/19.10, but will also affect older Ubuntu releases (probably all the way down to xenial).

@CAN: Yes, a qemu patch is also required. For previous distros another LP is available.:  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1842916

s390: add support for IBM z15 machines

Add detection for machine types 0x8562 and 8x8561 and set the ELF platform
name to z15. Add the miscellaneous-instruction-extension 3 facility to
the list of facilities for z15.

And allow to generate code that only runs on a z15 machine.

Kernel SRU request submitted:
https://lists.ubuntu.com/archives/kernel-team/2019-September/thread.html#103839

Patch a0e2251132995b9 is a kernel patch, thus this is certainly not something we need to track in the upstream QEMU bugtracker.

The  QEMU patch is

commit 7505deca0bfa859136ec6419dbafc504f22fcac2
s390x/cpumodel: Add the z15 name to the description of gen15a

Hi,
since [1] doesn't change the identifier (it stays gen15a), so the only thing that is changing is the description of e.g. seen here:
$ qemu-system-s390x -cpu ? | grep gen15
s390 gen15a-base     IBM 8561 GA1                        (static, migration-safe)
s390 gen15a          IBM 8561 GA1                        (migration-safe)
s390 gen15b-base     IBM 8562 GA1                        (static, migration-safe)
s390 gen15b          IBM 8562 GA1                        (migration-safe)

As far as I see it has no functional impact - is that correct?

Under that assumption I'm considering this for Eoan as prio-medium (as it is still open), and for SRUs as whishlist.
It might be added there "along" some other SRU later, but isn't reasonable on its own triggering downloads for millions of users - if you don't agree please outline why we'd need this any sooner there.

FYI: Please note that changing the actual type "gen15a" to something else is even less of an option at least for SRUs as people could use it already and the update would break them.

[1]: https://git.qemu.org/?p=qemu.git;a=commit;h=7505deca

Test build [1] seems ok and MP opened [2].
But the change is trivial so that should be quick ...

[1]: https://launchpad.net/~paelzer/+archive/ubuntu/fix-1842774-z15-model-name-eoan
[2]: https://code.launchpad.net/~paelzer/ubuntu/+source/qemu/+git/qemu/+merge/373118

In fact while I was waiting to submit this the MP got reviewed.
Uploaded to Eoan ...

But since beta freeze is in place acceptance there might have to wait a few days.

------- Comment From <email address hidden> 2019-09-24 09:11 EDT-------
Yes this only updates the description. The name gen15a can not be changed without hurting migration compatibility.
We are looking into adding an alias for cpu names, but this would be a future change.
With that medium priority is fine.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

@SRU Team:
As outlined above this is important for IBM to get product names right everywhere. But at the same time this is "only" a change in a description which doesn't qualify an SRU on its own. So we agreed to only upload it once there is another SRU.

I now have an Qemu SRU for Bionic that I want to group this with, this will make the Disco SRU go without any other changes to not have Bionic->Disco->Eoan switch back and forth. Therefore I'll upload it for Disco as well when doing so.

disco is also good.

Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report.  In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
