kernel-devsrc is responsible for creating and a packaging an environment appropriate for kernel development (on or off target). To create this support, we only need to copy/install the results of the virtual/kernel providers build in the staging dir ... with some minor manipulations to the source tree (.git removal and a clean up). This produces a source tree that is capable of rebuilding the kernel on the target. Installing the kernel-devsrc package on a target (along with a toolchain) is all that remains to be done. $ cd /usr/src/kernel $ make oldconfig $ make -j2 bzImage (From OE-Core rev: 6412dc1df434f774c434ec08bf9b3706edb756f2) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
