kernel-yocto.bbclass: Reset to exiting on non-zero return code at end of task

2022-06-22T22:46:32+00:00

Several tasks deactivate exiting on non-zero return codes via set +e because they run subcommands that have legitimate non-zero return codes. However when appending to those tasks, this behavior is not expected and can lead to builds silently proceeding in case of an error. Therefore reset the default behavior at the end of the respective tasks via set -e.

kernel-yocto: Simplify no git repo case in do_kernel_checkout

2021-08-18T17:00:19+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.

kernel-yocto: provide debug / summary information for metadata

2021-06-03T15:30:56+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: 8c299837622795408f4e4a9e8c2b3b3d6f409acd) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie (cherry picked from commit b95b11e130e91cb7c5e65f0f9a1c655bcbcbc919) Signed-off-by: Steve Sakoman Signed-off-by: Richard Purdie

kernel-yocto: add KBUILD_DEFCONFIG search location to failure message

2020-10-06T13:15:22+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: checksum all modifications to available kernel fragments directories

2020-09-10T18:07:40+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.

kernel-yocto: account for extracted defconfig in elements check

2020-07-23T15:51:07+00:00

The test for whether or not scc should to invoked to generate a config.queue was missing the newly created sccs_defconfig variable. We need to test for that variable as well, or we may miss generating the config.queue in some cases.

kernel/yocto: fix search for defconfig from src_uri

2020-07-16T21:28:40+00:00

Fetcher provides full paths to defconfig and scc files, which awk comparison operator does not catch during construction of src_uri_defconfig and sccs_from_src_uri lists. This causes the src_uri_defconfig variable to come out empty, and fails further validation if defconfig is only supplied via SRC_URI. Replace comparison operator with awk match function which searches for sub-string during filtering, effectively placing defconfig from SRC_URI into src_uri_defconfig and scc files in sccs_from_src_uri respectively.

kernel/yocto: ensure that defconfigs are processed first

2020-07-16T21:28:40+00:00

It is uncommon that a BSP definition and a defconfig are used in a single configuration. That being said, it is a valid way to organize kernel configuration meta data. When a defconfig is used, either on the src_uri or from in the kernel tree, it is normally expected that it is the baseline, with all options applied on top of it. With this commit, we detect either type of defconfig and ensure that it is used first, followed by the fragments in their previous order. This allows existing configuration stacks to remain the same, while ensuring that a defconfig combined stack works as expected.

kernel-yocto.bbclass: Fix deps when externalsrc is used

2020-05-05T07:45:30+00:00

do_kernel_configme was recently removed from SRCTREECOVEREDTASKS so this task still runs when externalsrc is used. This task normally runs after do_patch but when externalsrc is used, do_patch is removed and this ordering restriction does nothing. This allows bitbake to execute do_kernel_configme too early, causing races with do_unpack. This is fixed by adding in a dependency on do_unpack when externalsrc is used.

kernel-yocto.bbclass: Support config fragments with externalsrc

2020-03-10T23:20:33+00:00

The merging of config fragments is performend in the do_kernel_configme task and so config fragments will not be supported when this task is removed from the dependency tree. kernel-yocto adds additional tasks which may modify the source directory to SRCTREECOVEREDTASKS so that they are removed when using externalsrc. However, do_kernel_configme should be safe to use, the only modification to the source tree is the potential creation of the '.kernel-meta' directory and the '.metadir' file.
