classes: Update classes to match new bitbake class scope functionality

2022-08-12T14:27:17+00:00

Move classes to classes-global or classes-recipe as appropriate to take advantage of new bitbake functionality to check class scope/usage. (From OE-Core rev: f5c128008365e141082c129417eb72d2751e8045) Signed-off-by: Richard Purdie

classes: Add SPDX license identifiers

2022-08-12T10:58:01+00:00

As stated in our top level license files, the license is MIT unless otherwise stated. Add SPDX identifers accordingly. Replace older license statementa with the standardised syntax. Also drop "All Rights Reserved" expression as it isn't used now, doesn't mean anything and is confusing. (From OE-Core rev: 081a391fe09a21265881e39a2a496e4e10b4f80b) Signed-off-by: Richard Purdie

classes: Add copyright statements to files without one

2022-08-12T10:58:01+00:00

Where there isn't a copyright statement, add one to make it explicit. Also drop editor config lines where they were present. (From OE-Core rev: 880c1ea3edc8edef974e65b2d424fc36809ea034) Signed-off-by: Richard Purdie

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

2022-06-04T10:28:23+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.bbclass: say what SRC_URI entry is being dropped

2022-05-15T07:57:15+00:00

If there is a defconfig set by KBUILD_DEFCONFIG and something that looks like a defconfig in SRC_URI, the SRC_URI is dropped. This happens even if the entry in SRC_URI is called my_defconfig_frag.cfg. Arguably, this is a bug and the behaviour should be changed, but for now if we're going to remove entries from SRC_URI we should make it clear what entry is being removed.

kernel-yocto: allow patch author date to be commit date

2022-04-30T21:00:20+00:00

In situations where a buid needs to be reproducible, it is sometimes desireable to use a patches author date, versus the time when it is applied. This generates a consistent hash between different patch applications. We leverage the existing KERNEL_DEBUG_TIMESTAMPS to trigger the use of a new option to kgit-s2q. This allows us to use the author date in a reproducible configuration, but disable it if we need the current time/date.

kernel-yocto.bbclass: Fixup do_kernel_configcheck usage of KMETA

2022-04-21T19:58:15+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: f4a3e80a4a6f4f709d09940dcaf45b2b00654496) Signed-off-by: Russ Dill Signed-off-by: Luca Ceresoli 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
