Description Dan Horák 2009-09-16 08:39:39 EDT
Created attachment 361265 [details] patch with s390x support Currently QEMU can't be built on s390x because mainly the tcg part is missing. It looks like that Ulrich Hecht from SUSE is working on full s390x support for upstream QEMU (see http://lists.gnu.org/archive/html/qemu-devel/2009-07/msg01910.html for recent patches). I took them and updated for qemu-kvm, the result is in attachment. I don't think there is an immediate need for a s390x emulator, but we need the other ones to be built on s390x.
Comment 3 Glauber Costa 2009-09-16 08:51:23 EDT
I am not that used to that platform, but as far as I understand, host and target support for s390 should be orthogonal. What we need to support your case is pieces of patches 2 and 3. Also, how urgent, and on which basis does your request come? If those patches are likely to be included upstream, they will eventually reach our package anyway
Comment 4 Dan Horák 2009-09-16 10:40:09 EDT
Some related discussion is in bug #523228 and it all depends on what will be supported configurations in RHEL-6.
Comment 5 Mark McLoughlin 2009-09-21 09:01:38 EDT
Please keep the Fedora request separate from the RHEL6 request When this gets upstream, we'll certainly enable it in Fedora I'm a bit reluctant to include the patch because, if for whatever reason, it stops working we'll just disable it again rather than trying to fix it. And I'm not keen on removing features once we've added them Dan: would you be willing to maintain the patch for Fedora until it gets upstream? e.g. if we re-base to an upstream would you fix up the conflicts? Or if there are bugs, could we assign them to you?

I will track the situation in upstream and eventually open a new request, if some action from qemu maintainers will be needed.
