2014-12-20kernel: Rearrange for 1.8Richard Purdie1
In 1.8 we want to streamline the kernel build process. Basically we currently have multiple copies of the kernel source floating around and the copying/compression/decompression is painful. Lets assume we have a kernel source per machine since in most cases this is true (and we have a sysroot per machine anyway). Basically, instead of extracting a source into WORKDIR, then copying to a sysroot, we now set S to point straight at STAGING_DIR_KERNEL. Anything using kernel source can then just point at it and use: do_configure[depends] += "virtual/kernel:do_patch" to depend on the kernel source being present. Note this is different behaviour to DEPENDS += "virtual/kernel" which equates to do_configure[depends] += "virtual/kernel:do_populate_sysroot". Once we do this, we no longer need the copy operation in do_populate_sysroot, in fact there is nothing to do there (yay). The remaining part of the challenge is to kill off the horrible do_install. This patch splits it off to a different class, the idea here is to have a separate recipe which depends on the virtual/kernel:do_patch and just installs and packages the source needed to build modules on target into a specific package. Right now this code is proof of concept. It builds kernels and kernel modules. perf blows up in do_package with issues on finding the kernel version which can probably be fixed by adding back the right bit of do_install, and adding a dependency of do_package[depends] += "virtual/kernel:do_install" to perf. The whole thing needs a good write up, the corner cases testing and probably a good dose of cleanup to the remaining code. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2010-05-20linux-kernel-base.bbclass: merge version detection updates from upstreamJoshua Lock1
Kernels after 2.6.33 store the utrelease.h file, used to detect the kernels version, in a different location. Merged from oe.dev Signed-off-by: Joshua Lock <josh@linux.intel.com>
