* kernel/bbclass: rework kernel and module classes to allow for building ↵Darren Hart2011-03-231-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | out-of-tree modules The existing infrastructure uses an external build tree which references the kernel source in the work dir. If run with rm work, building external modules will fail. This patch places a configured source tree in sysroots. Striking a balance between minimal size and minimal maintenance is difficult. A fully configured tree is about 500MB after a clean. This version leans on the side of caution and removes only the obviously unecessary parts of the source tree to conserve space, resulting in about 170MB. The arch directories would be some additional pruning we could do. Given examples from the devel package from distributions, I suspect this size could be reduced to 75MB or so, but at the cost of a much more complex recipe which is likely to require a great deal more maintenance to keep current with kernel releases. Care is also taken to clean the hostprogs in scripts, and the modules are responsible for building them as needed. Although it is unclear to me if this is really necessary, especially considering that modules put these bits back as soon as they compile. If we are not generating an sstate package, I suspect we can ignore these. Please try this with your modules and let me know how it does. I tried to take non linux-yocto kernel recipes into account, but I have only tested with linux-yocto and the hello-mod recipe so far.

* module: build hostprogs for each moduleDarren Hart2011-03-041-1/+11
| | | | | | | | | | | | | | | | | | | | | This fixes [BUGID #241] The kernel hostprogs are built for the host architecture. They should not be deployed to the target, and they should not be included in an sstate package which might get reused on a host of a different architecture. As we don't build many out-of-tree modules, this patch takes the approach of building the hostprogs as part of the module compile process with a do_compile_prepend() routine in module.bbclass. We don't have to clean the hostprogs as modules depend on the kernel being populate_staging, so its done with the staging directory by the time we run.
