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

kernel-yocto: add KBUILD_DEFCONFIG search location to failure message

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.

kernel-yocto: only replace leading -I in include paths

We just want to remove the first '-I' in $d, hence removing the g' of sed avoid changing the real path which is include '-I' We also add an anchor to the regex to only match -I at the start of the path.

kernel-yocto: checksum all modifications to available kernel fragments directories

2020-08-28T06:08:37+00:00

This is based on the patch from Zhaolong Zhang [kernel-yocto: checksum indirect cfg and scc files] While the recommended manner to share/reuse feature fragments is to maintain them in a kernel-meta repository and track the changes via the standard SRCREV fetcher mechanism, that method is not always practical for small sets of features or for quick testing of changes. These other flows use .scc files on the SRC_URI. It has been noted that config fragments or other features indirectly included by those .scc files will not trigger the kernel meta-data to be re-run and hence a build can continue with stale data (or not be triggered at all). To solve this issue, we can collect the directories that are searchable via FILESEXTRAPATHS and add them to the do_kernel_metadata task checksum. This allows modifications, additions and removals from the potential kernel feature directories to trigger a re-execution of the meta data task.
