Aloha all, Does anyone know if something similar has started within openSUSE? None of the work being undertaken by Fedora at this point is covered by any restrictions, so there should be nothing stopping openSUSE from doing something similar. I'm happy to make a start, so long as someone can confirm what process/steps is desired for the bootstarp process on openSUSE. Many thanks, Andy ---------- Forwarded message ---------- From: Al Stone Date: 21 November 2012 21:30 Subject: [fedora-arm] ARMv8 Bootstrap Project To: arm@lists.fedoraproject.org Howdy.

Howdy.

It's time to announce a little project I've been working on for the last few weeks: the ARMv8 bootstrap project for Fedora.

Last time the bootstrap required Adrians magic hands :). The main problem I'm facing with AArch64 bootstrap is speed. The emulator is incredibly slow. Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

I can't comment about Adrians powers of voodoo :) With regards to speed, yes it is slow but there is no QEMU support yet so it will have to do. Does SUSE have a Cloud instance that we could use to parellelise the build? If not, maybe we could look at getting something up on AWS? -- Andrew Wafaa IRC: FunkyPenguin GPG: 0x3A36312F -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Yes, we have a cloud, but the bootstrap can't be parallelized and needs quite a bit of manual intervention every now and then :). So that won't help _too_ much. Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Without qemu support the only way is to go the cross compile approach. B1-Systems is currently pushing patches for OBS to support this, but since it is invasive it is a time consuming work to merge them. However, it may be interessting to run another OBS instance where we just take all of their patches and try to cross build for aarch64. In any case, it would be helpfull if people can find out which patches esp. for binutils and gcc are used to support that aarch and adapt them for the suse packages, so that they apply at least. -- Adrian Schroeter SUSE Linux Products GmbH email: adrian@suse.de -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

But please do not wait for OBS for that task. It is absolute okay to import manual cross build binary packages from a trusted person into OBS for initial setup. -- Adrian Schroeter SUSE Linux Products GmbH email: adrian@suse.de -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

It would be useful to see how things compare between v8 & v7, but not essential. If it is possible to do thisa it could be useful.

Do you mean go through [0] and pull out all the aarch64 patches and try and apply them to factory based packages? Interestingly enough, Fedora also have a list of unchanged packages [1] which may help with prioritising what packages need work. Not sure how similar things would be for us, but...

In this early phase this is not really important, I guess. Atm all dirty tricks are allowed to get initial versions of packages :)

Yes, esp for binutils and gcc in first place. bye adrian -- Adrian Schroeter SUSE Linux Products GmbH email: adrian@suse.de -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
