Hi,
I'd like to try and see if we can get a secondary arch sort of effort underway to build and deliver a PowerPC ( power7 ? ) distro based on the CentOS-7.
Power hardware is hard to come by, and we're going to mostly bootstrap from the powerpc community resources hosted at OSUOSL - but we do have enough resources to get the buildsystem up and keep it running for the ppc64 and ppc tree's. To complement this, we also have a power7 machine for the time being, on loan from a sponsor. But its future is uncertain, we might only have it for another 6 months. The resouces at OSL should, however, persist.
Also, as most people on this list will realise - there is quite a lot of momentum inside the project, so the existing contributors dont have enough time to contribute towards another arch as well, so the effort to run this will need to come from the community.
So the purpose of my email is two fold, (1) is there enough community interest to undertake this effort ? and (2) are there enough community folks willing to put in the time to make it happen. Ideally some of you lot will have local hardware to test and qa the builds as well.
Regards,

at the moment I can provide a Power5+ machine (besides that, an older IntelliStation 275, which features a Power4+ and thus might be plain too old), with perspectively another Power6+-based machine, soon.

I think so. The Fedora ppc-Port is humming along very nicely.
and (2) are there enough community folks willing to put in the time to make it happen. Ideally some of you lot will have local hardware to test and qa the builds as well.
I can provide rack space and the machines I have, including access via console for selected users. Furthermore, I could provide rack space and unlimited traffic for any machine of decent size that would be placed here, if needed.
Last year I started to rebuild RHEL 6 SRPMs on my Power5+ machine, however, due to lack of spare time, I came to a point where efforts stopped.

Best,
Timo

So, we have enough to do the builds - what we need are people to do the tracking of buildlogs, help with the bootstrap for ppc ( ppc64 is mostly good, and we can import noarch from x86 builds ), and ideally we need some of these people to have local hardware to test on, since thats not something we can provide on.

yeah, same same. How are you placed for time at the moment ?

given that my RHEL 7 iso boots on that 285. I'll check it. Had some issues last time I tried.

Short. Guess from Monday on it will be better.

Got approval to use one of our Power7 boxes, so I can do local testing.
What is needed for the ppc bootstrap?

Effectively, we need a git repo ( I'll do one ) that holds mock configs, that are then injected into the buildsystem. The buildsystem keeps looping over srpms till it gets to a point where either they are all built, or there are only failing rpms left in the stack and each one has failed 5 times.
each new commit to the git repo restarts the buildsystem ( if its paused at the moment )
we need to bootstrap all of ppc64 ( has someone got a list from 7rc ? ) and we need enough ppc ( 32bit stuff ) to build the multilib side of things ( again, who's got a list from 7rc ? )
I will setup some repos that can be used for the bootstrap.
the OSL folks are going to reprovision some lpar's for us to use as the buildsystem, should be done in a day or so ( but that should not stop us from going ahead and getting the mock configs setup, or atleast a few basic templates ).
specifics, including example mock configs later today.
Work from OSL folks ( they might even be on this list! ) is that we are likely to have builders setup by Monday.
I'll get the git repos etc in place before then, so we have something to play with.

Should we have seen any traffic on centos-build from the ppc(64) side of the house yet? I'd tried to set filters to weed out all the success and x86_64/i386 messages, but I'm a little concerned now (particularly since JH mentioned the ppc64 build in another thread) that I'm missing stuff I should be looking at.
Thanks,

no ppc builds for c7, nothing worth writing home about anyway.
the nodes at OSL are up, just running out of b/w getting them online along with the build metadata. Hopefully early this coming week.

Yeah, that's something we discussed already several times, and some people even noticed the #centos-ppc channel on Freenode .. :-)
Power hardware is hard to come by, and we're going to mostly bootstrap from the powerpc community resources hosted at OSUOSL - but we do have enough resources to get the buildsystem up and keep it running for the ppc64 and ppc tree's.

So the goal would be to have a "secondary arch" support, but even that can be divided into two things : ppc64 and ppc. ppc64 is the default target (for quite some time) upstream, but I expect the ppc part being the most difficult one to rebuild (with all the different patches and optimization even for Power6+ - depending on the release -)
Also, as most people on this list will realise - there is quite a lot of momentum inside the project, so the existing contributors dont have enough time to contribute towards another arch as well, so the effort to run this will need to come from the community.
That's true, so "let's surf on the wave" ....

I've asked my management for the use of one of our Power7 boxes. I don't think we'll be able to expose it to the outside world, but we should be able to build and test locally. We're also very interested in having the ability to build and run 32-bit PPC applications (although we don't need a full ppc32 distro).
