[opensuse-kernel] Kernel for ppc64le(not yet) and for OBS VM's
by Adrian Schröter 09 Jan '14

09 Jan '14

Hi, I have two commits in my git repo which I would like to get merged: https://github.com/adrianschroeter/kernel-source.git 1) A config for ppc64le. The kernel will still not compile due to code problems, but I like to get it merged anyway to show where we are with our ppc64le port. The standard kernel script tools did not work for me, but the kernel build in openSUSE:Factory:PowerLE project does accept at least the config. 2) A new spec file to repackage the kernel in a way that it will get picked up by OBS VM builders. We need this for a number of reasons: * ppc64 little endian switch on big endian hosts * build jobs which require further kernel modules will be able to load them now, since te code stream does match the running kernel (eg. kiwi using LVM tools) * QA checks depending on the kernel * validation of our kernels in general, the entire distro will use the the distro kernel during building. The reason why I want to have this spec file as part of the kernel package is that it should be also branched, when someone is branching any kernel-* package. OBS does create branches for all local linked packages, so the new and modified kernel will be used also directly in this project branching the kernel. To be discussed: shall we create the initrd in a way avoiding root permissions? On the other hand, we do test our default mkinitrd tool this way. It broke often enough in the past ... -- Adrian Schroeter email: adrian(a)suse.de SUSE LINUX GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 21284 (AG Nürnberg) Maxfeldstraße 5 90409 Nürnberg Germany -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] sequence-patch: Add support for xz-compressed archives and patches
by Jean Delvare 07 Jan '14

07 Jan '14

Hi all, While kernel.org still offers bz2 archives for download, the discussion about dropping them and only leaving gz and xz is coming back every now and then. So I believe we should anticipate a future removal of bz2 archives and get our scripts ready to deal with xz-compressed archives now. If nothing else, that would encourage everyone to use xz-compressed archives whenever possible, which is a great saving of network bandwidth and storage space, plus decompression is twice as fast as with bz2. Thus I'd like to add support for xz-compressed files to sequence-patch for a starter. I'm attaching the patch. It's only tested locally (outside of the suse network) so not all code paths were tested. Some more testing and review would be welcome. We could also consider using xz to compress all tar files in tar-up.sh (and update the spec files accordingly.) This may make submission somewhat slower, as compressing with xz is significantly slower than with bzip2, but this would save some upload time, storage space in IBS/OBS and should also improve the build times by a small bit. -- Jean Delvare Suse L3 Support
