kernel-yocto.bbclass: Fixup do_kernel_configcheck usage of KMETA

2022-05-04T12:07:33+00:00

The do_kernel_configcheck task requires a meta directory, normally set by ${KMETA}. The meta directory is taken as a relative path from ${S}: outfile = "{}/{}/cfg/mismatch.txt".format( s, kmeta ) However, when checking for the presence of ${KMETA} the current working directory is searched. This will almost always fail and "kgit --meta" is used instead. If the user does have a path in their current working directory that matches the ${KMETA} variable but the path is not present within the kernel source directory, the build will fail if it tries to write config errors/ warnings to that path. If ${KMETA} is not set, the same problem exists with the hard-coded "meta" directory. Fix these issues by checking for ${KMETA} within ${S} rather than the current working directory. Additionally, drop the hardcoded backup directory "meta" as it hasn't been functioning and probably has no users (From OE-Core rev: c322272a51d923cda9b0e5e388e32b7dd3a6bd22) Signed-off-by: Russ Dill Signed-off-by: Luca Ceresoli (cherry picked from commit f4a3e80a4a6f4f709d09940dcaf45b2b00654496) Signed-off-by: Steve Sakoman Signed-off-by: Richard Purdie

kernel-yocto: Simplify no git repo case in do_kernel_checkout

2021-08-04T09:38:26+00:00

If the kernel sources are not fetched via git, a local git repository is created in do_kernel_checkout. In this case we know that there will be no remote branches and we will already be on the correct branch (since only one branch will exist). So we can simplify things by skipping these steps. This also removes the assumption that the default git branch name will be "master". Prior to this change, the final git checkout command in do_kernel_checkout could fail if a local git repo was created and the user had changed init.defaultBranch in their gitconfig.

Convert to new override syntax

2021-08-02T14:44:10+00:00

This is the result of automated script conversion: scripts/contrib/convert-overrides.py converting the metadata to use ":" as the override character instead of "_". (From OE-Core rev: 42344347be29f0997cc2f7636d9603b1fe1875ae) Signed-off-by: Richard Purdie

linux-yocto-dev: base AUTOREV on specified version

2021-06-17T12:42:31+00:00

linux-yocto-dev tracks the latest mainline kernel, and uses standard/* for that support. Archived -dev versions are under v/standard/base. This policy works, except that a released branch will still follow the new kernel versions, causing potential breakage with newer kernels than are supported in that release. Rather than lock the SRCREVs and update branches in old releases, we can preserve the AUTOREV nature of -dev, and allow them to switch automatically to the archived branch based on the LINUX_VERSION in the -dev recipe (which is unchanged in the release branch). This is consistent with the other branch switching done for the kernels and with the -dev workflow.

kernel-yocto: provide debug / summary information for metadata

2021-05-18T22:52:53+00:00

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 Signed-off-by: Richard Purdie

kernel-yocto.bbclass: chdir to ${WORKDIR} for do_kernel_checkout

2021-04-24T16:53:05+00:00

It chdirs to ${S} at the beginning of task do_kernel_checkout. Then it removes ${S} when it still resides in ${S}. It may fail to run the task do_kernel_checkout when bitbake is called by third-part wrapper script. So chdir to ${WORKDIR} by default for do_kernel_checkout. And it will chdir to ${S} afterwards in task do_kernel_checkout. (From OE-Core rev: cf0e3397d3f86c7ea1f3c66c50a44d6205f5921b) Signed-off-by: Kai Kang Signed-off-by: Richard Purdie

2020-09-25T09:54:30+00:00

It was pointed out that since the check for the existence of KBUILD_DEFCONFIG knows where it is looking, that should be part of the error/log message. We only look in one location for the defconfigs, so add where we checked to the message.
