To support configurations where active development is not being done within the oe/bitbake build environment and restricted bandwidth situations, this commit allows the SRC_URI to point to a kernel tgz instead of a full git repository.
Outside of the upstream tgz instead of a kernel git repository, the restrictions, config and patch process is the same as any linux-yocto-custom recipe. An example linux-yocto-custom based recipe would have a configuration like this to build the 3.7 kernel, using an externally supplied config, from the 3.7 tgz: SRC_URI = "http://kernel.org/pub/linux/kernel/v3.0/linux-3.7.tar.bz2"; PV = "3.7" S = "${WORKDIR}/linux-3.7" SRC_URI[md5sum] = "5323f3faadd051e83af605a63be5ea2e" SRC_URI[sha256sum] = "dc08d87a579fe2918362e6666e503a95a76296419195cb499aa9dd4dbe171a9e" [YOCTO #2686] Signed-off-by: Bruce Ashfield <bruce.ashfi...@windriver.com> --- meta/classes/kernel-yocto.bbclass | 34 +++++++++++++++++++++------------- 1 file changed, 21 insertions(+), 13 deletions(-) diff --git a/meta/classes/kernel-yocto.bbclass b/meta/classes/kernel-yocto.bbclass index 92ede6a..8494c16 100644 --- a/meta/classes/kernel-yocto.bbclass +++ b/meta/classes/kernel-yocto.bbclass @@ -158,22 +158,10 @@ do_kernel_checkout() { mkdir -p ${S} # We can fix up the kernel repository even if it wasn't a bare clone. - # If KMETA is defined, the branch must exist, but a machine branch - # can be missing since it may be created later by the tools. mv ${WORKDIR}/git/.git ${S} rm -rf ${WORKDIR}/git/ cd ${S} - if [ -n "${KMETA}" ]; then - git branch -a | grep -q ${KMETA} - if [ $? -ne 0 ]; then - echo "ERROR.
