Hi Janosh,
the patch is fine to be added to the new qemu in the next Ubuntu Release.
To be able to add it to Bionic/Cosmic as requested I'd need some sort of a test case that can verify the fix working in the backported version as well.
308 was re-IPL, would you have a test case to share that we could use to test unknown diag 308 subcodes that trigger the new code?

The attached test case is a minimal kernel generated via the kvm unit test repo.
It has to be executed via qemu kernel boot, the command and expected output in both cases are below.
The path to qemu at the start of the command might need adjustment.

Command:
/usr/local/bin/qemu-system-s390x -nodefaults -nographic -machine s390-ccw-virtio,accel=kvm -chardev stdio,id=con0 -device sclpconsole,chardev=con0 -kernel s390x/diag308.elf

Output on unfixed qemu:

Hi Heinz,
I added and tested it when I was prepping the SUR template on 22nd January.
Currently this is already part of the qemu in Disco-proposed.
=> https://launchpad.net/ubuntu/+source/qemu/1:3.1+dfsg-2ubuntu1

I wait for it to fully migrate into Disco which then will unblock preparing the related SRUs for the former releases. That migration (into Disco) is currently blocked by bug 1813730 which is being worked on by rbalint. If that bug seems to stall I will ask for a test override (to ignore the bad result of livecd-rootfs temporarily).

        reference 256k path

        handle incoming migrations from former releases.
    - d/control-in: Disable capstone disassembler library support (universe)
  * Added Changes:
    - d/p/ubuntu/define-ubuntu-machine-types.patch: update machine type changes
      for qemu 3.1 in the Ubuntu Disco release
    - d/p/ubuntu/lp-1759509-* fix waking up VMs from dompmsuspend (LP: #1759509)
    - Move s390x roms to a new qemu-system-data-s390x

        some SLOF bits stripped in DFSG to be able to build s390x-netboot roms
        As that hack to build s390-ccw.img rom can't build s390x-netboot.img
        replace it with a build-indep using the upstream makefiles.
        This is less prone to miss future changes/fixes that are done to the
        makefiles

      unimplement.patch: properly return archicture defined exception

FYI the backport for qemu 2.11 is prior to [1]
Since the requested patch doesn't need the return address for its own purpose I'll just use:
program_interrupt(env, PGM_SPECIFICATION, ILEN_AUTO);
which I think should work fine.

FYI - the fix for this bug as an SRUs is ready and testable from a PPA for
Cosmic [1] and Bionic [2].

I'm gonna check the test instructions myself by testing that from the PPA before uploading to the SRU queue.

In addition I'll push these PPAs through the automated regression tests for qemu/libvirt.

@SRU Team - I beg your pardon and wanted to make clear that I try to care for my SRUs.
This looks all good except autopkgtest failing for other reasons.
Those are handled in bug 1817721.
IMHO: Feel free to release this as-is and/or to help getting the MP associated to 1817721 accepted.
