[opensuse-buildservice] Making kernel modules for specific kernel versions
I have been looking through http://www.novell.com/communities/node/9226/using-opensuse-build-service-cre... to see how to make kernel drivers in OBS. I have one question: can I specify the specific kernel version to be used? For example, openSUSE 11.2 came out with some release of the kernel, and there have since been updates. I would like to make the kernel driver for the original kernel that was delivered with openSUSE. How would I specify that? Is there a better way to do this? Is it possible to make a kernel driver that would load into any release of the kernel for an openSUSE release? For example, if I compile the driver for the -desktop kernel, can I do so in such a way that it can be installed on all -desktop kernels for that openSUSE release? -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.

Build against openSUSE:11.2 project. When you want to build against the current released update kernel, build against openSUSE:11.2:Update instead.

We do not store in-between updates atm.
For example, if I compile the driver for the -desktop kernel, can I do so in such a way that it can be installed on all -desktop kernels for that openSUSE release?

As Adrian said, you can build either against openSUSE:11.2 (shipping kernel) or openSUSE:11.2:Update (current update kernel).

Yes, you just build a KMP... ... KMPs can be used for multiple kernels (the built against one and laters), if the kabi for those stays stable. While we do not guarantee that for openSUSE, we try to keep it that way. A KMP built against the 11.2 GA kernel will for instance still work with the current update kernel.

I am a real newbie with OBS. I have one simple package. So bear with my simple questions... If I make a kernel driver package, can I trigger it getting rebuilt automatically when a kernel update is released? Without me having to trigger anything by hand? It is not a matter of laziness so much as wanting to be sure there is a version of the driver for each openSUSE kernel and update. Section 4.6 in the link I referenced implies that this is possible. Would it happen automatically if I build against openSUSE:11.2:Update and a kernel update is released? -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.

Often, KMPs still work across a minor kernel update, by means of the weak-modules mechanism.

It should. -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org
