kernel-yocto: allow multiple / shared kernel feature directories
To promote the reuse and sharing of configuration fragments this change allows any kernel-yocto based recipe to have multiple alternate git repositories which provide kernel feature directory trees listed on the SRC_URI. These feature directories are in addition to any in-tree kernel meta data branches that may be available (described via the KMETA variable in linux-yocto recipes). Features found within these directories can be used from recipes via the KERNEL_FEATURES variable. Features found within a feature directory are free to include any other features that are available in any directories. In both cases the path to a feature description (a .scc file) is relative to the root of a given feature directory (which is how existing .scc files work) The search order for features is determined by the order that repositories appear on the SRC_URI. Normal SRC_URI rules apply to any repository that is added as a kernel feature container. A SRCREV must be supplied and it must be unpacked to a unique directory, which is controlled via the "destsuffic" url parameter. In addition to these standard requirements, any kernel feature repository reference should identify itself via the "type=kmeta" url parameter. If type=kmeta is not supplied, the repository will not be processed for kernel features. As an example, the following in a linux-yocto bbappend makes two additional feature directories available to KERNEL_FEATURES and fragments. SRC_URI += "git://git.yoctoproject.org/yocto-kernel-cache;protocol=git;branch=master;type=kmeta;name=feat1;destsuffix=kernel-cache/" SRC_URI += "git://${KSRC_linux_yocto_3_4};protocol=file;branch=meta;name=feat2;type=kmeta;destsuffix=kernel-features-experimental/" SRCREV_feat1 = "${AUTOREV}" SRCREV_feat2 = "${AUTOREV}" (From OE-Core rev: 02ad603a104b70ab74548c8018e738bfbb3c59db) 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>
