From 4b6f29ddb00480896f47d96ea376f3a6f6d8451e Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Mon, 11 Jun 2012 16:21:12 -0400 Subject: meta-skeleton: add linux-yocto-custom reference recipe Adding a skeleton/refrence recipe for using a subset of the yocto kernel tools against kernel git repositories. Sample/reference configuration fragments, features and a patch are provided and documented in the recipe. From the recipe itself: Provides an example/minimal kernel recipe that uses the linux-yocto and oe-core kernel classes to apply a subset of yocto kernel management to git managed kernel repositories. Notes: kconfig(s): the kernel must be configured with a defconfig, or via configuration fragment(s). Either of these can be added via bbappend. patches: patches can be merged into to the source git tree itself, added using standard bbappend syntax or controlled via .scc feature descriptions (also via bbappends) example configuration addition: SRC_URI += "file://smp.cfg" example patch addition (for kernel v3.4 only): SRC_URI += "file://0001-linux-version-tweak.patch example feature addition (for kernel v3.4 only): SRC_URI += "file://feature.scc" Warning: Building the sample kernel tree (kernel.org) without providing any configuration will result in build or boot errors. This is not a bug it is a required element for creating a valid kernel.
