kernel-yocto: provide debug / summary information for metadata
It was mentioned that when developing a BSP, the information about what definition was used, or what fragments have been applied is not obvious and requires looking at the code. With this change, we can trigger a full summary of the meta data gathering phase when KCONF_AUDIT_LEVEL > 0. Sample output follows: NOTE: do_kernel_metadata: for summary/debug, set KCONF_AUDIT_LEVEL > 0 NOTE: kernel meta data summary for qemux86-64 (standard): NOTE: ====================================================================== NOTE: BSP entry point / definition: /build/tmp/work/qemux86_64-poky-linux/linux-yocto/5.10.34+gitAUTOINC+bca3bfbc74_85c17ad073-r0/kernel-meta/bsp/common-pc-64/common-pc-64-standard.scc NOTE: Fragments from SRC_URI: /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/xt-checksum.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/ebtables.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/vswitch.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/lxc.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/docker.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/cgroup-hugetlb.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/xen.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/kubernetes.scc NOTE: KERNEL_FEATURES: features/nfsd/nfsd-enable.scc features/debug/printk.scc features/kernel-sample/kernel-sample.scc features/netfilter/netfilter.scc cfg/virtio.scc features/drm-bochs/drm-bochs.scc cfg/sound.scc cfg/paravirt_kvm.scc features/scsi/scsi-debug.scc features/gpio/mockup.scc features/aufs/aufs-enable.scc cfg/fs/flash_fs.scc cfg/virtio.scc NOTE: Final scc/cfg list: /build/tmp/work/qemux86_64-poky-linux/linux-yocto/5.10.34+gitAUTOINC+bca3bfbc74_85c17ad073-r0/kernel-meta/bsp/common-pc-64/common-pc-64-standard.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/xt-checksum.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/ebtables.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/vswitch.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/lxc.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/docker.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/cgroup-hugetlb.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/xen.scc /poky/meta-virtualization/recipes-kernel/linux/linux-yocto/kubernetes.scc features/nfsd/nfsd-enable.scc features/debug/printk.scc features/kernel-sample/kernel-sample.scc features/netfilter/netfilter.scc cfg/virtio.scc features/drm-bochs/drm-bochs.scc cfg/sound.scc cfg/paravirt_kvm.scc features/scsi/scsi-debug.scc features/gpio/mockup.scc features/aufs/aufs-enable.scc cfg/fs/flash_fs.scc cfg/virtio.scc (From OE-Core rev: b95b11e130e91cb7c5e65f0f9a1c655bcbcbc919) Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
