This can be done via: a) shared/reference clones b) shallow clones c) git initialized repos based on a tgz It should be noted that a) and b) can be fully functional linux-yocto repositories, while c) cannot. As such, the tgz option can be an enhancement to linux-yocto-custom, but will not be a promoted method, since it goes against several best practices and kernel workflow options .. it also has a not insignificant carrying cost. Option c) only supports minimal configuration fragments and no git based merge options or feature descriptions. Options a) and b) are not currently planned for 1.3, but are listed here to be complete and as options for 1.3+ (in particular option a)). 25607 1 bruce.ashfield 2012-09-24 14:41:20 +0000 Update: in case it isn't clear, this one is going to wait until 1.4, since we don't want (yet again) something completely different for the kernel. It makes sense to wait for the fetcher changes with shallow clones, or other similar options before adding this support, since it is essentially free after that. tgz support can be considered and stacked AFTER the initial low bandwidth options are working, since most of the issues with the revision chain not being complete will already be tested and solved. 29119 2 bruce.ashfield 2013-01-24 04:35:26 +0000 tgz support is possible with linux-yocto-custom, shallow clones are still not available, so we'll go with plan B for now. This still isn't ideal, but it does fit the linux-yocto-custom model, so we can live with it. 29527 3 bruce.ashfield 2013-02-05 16:04:27 +0000 kernel-yocto/linux-yocto-custom: support low bandwidth options 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] (From OE-Core rev: 08b3a282ce75a9972694f0c4379179505b9ec91f) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> 31905 4 andreea.b.proca 2013-04-11 11:17:59 +0000 Verified.
