kernel: add objtool to shared workdir when CONFIG_UNWINDER_ORC is set

2019-03-02T16:49:07+00:00

Based on: https://patchwork.openembedded.org/patch/148047/ When x86_64 enables CONFIG_UNWINDER_ORC [ORC (Oops Rewind Capability) unwinder for unwinding kernel stack traces], objtool is required to generate the required information. If we don't copy objtool to the shared workdir, out-of-tree modules cannot generate object files. For instance, meta-skeleton/hello-mod fails with: | make[3]: *** No rule to make target 'tools/objtool/objtool', needed by ...

kernel: Ensure an initramfs is added if configured

2019-02-25T10:43:06+00:00

If ${DEPLOY_DIR_IMAGE}/${INITRAMFS_IMAGE_NAME}.cpio does not exist, nor any of the compressed variants, nothing is copied to kernel build's ./usr directory. The code does not fail, but silently proceeds without a bundled initramfs. Change to fail and tell the user something is wrong. Also, if an initramfs is found, contrary to the comments, it does not stop at the first uncompressed/compressed cpio image found. Instead it keeps processing all so the last is used. Fix this to behave as per the comments. [YOCTO #12909] (Patch by Leon Woestenberg) (From OE-Core rev: 5b5604e288af755eb5553a97d26533445b2cf94b) Signed-off-by: Richard Purdie

meta: Fix Deprecated warnings from regexs

2019-01-16T15:35:07+00:00

Fix handling of escape characters in regexs and hence fix python Deprecation warnings which will be problematic in python 3.8. Note that some show up as: """ meta/classes/package.bbclass:1293: DeprecationWarning: invalid escape sequence \. """ where the problem isn't on 1293 in package.bbclass but in some _prepend to a package.bbclass function in a different file like mesa.inc, often from do_package_split() calls.

kernel.bbclass: Fix incorrect deploying of fitimage.initramfs

2019-01-07T10:54:13+00:00

When kernel-fitimage and initramfs is enabled using INITRAMFS_IMAGE_BUNDLE = "1", kernel do_deploy tries to deploy fitImage.initramfs with following error | install: cannot stat 'arch/arm64/boot/fitImage.initramfs': No such file or directory Skip deploying fitimage.initramfs, since fitimage does not create fitimage.initramfs (From OE-Core rev: 0f87f8522a2c1b5a7042738887952b98060fbd9d) Signed-off-by: Manjukumar Matha Signed-off-by: Richard Purdie

kernel: don't assign the build user/host

2018-12-08T17:17:01+00:00

The KBUILD_BUILD_USER and KBUILD_BUILD_HOST variables were assigned at the kernel class level, which made it impossible to override them in the local configuration. By setting only the default values of those variables in the kernel class, it is now possible to override them as expected.

kernel: use olddefconfig as the primary target for KERNEL_CONFIG_COMMAND

2018-11-14T11:14:38+00:00

As was warned by commit 312ee68752fa [kconfig: announce removal of oldnoconfig if used], oldnoconfig has been removed from the 4.20 kernel. So we switch our default mode to olddefconfig. commit fb16d8912 [kconfig: replace 'oldnoconfig' with 'olddefconfig', and keep the old name as an alias] introduced olddefconfig in the 3.10 kernel, we shuffle oldnoconfig to the fallback target. The fallback mode allows kernels between 3.10 and the currently listed oldest kernel of 3.2 to continue to configure.

kernel.bbclass: allow custom KERNEL_IMAGEDEST

2018-10-25T13:53:44+00:00

Some distros want to install the kernel in a custom location other than /boot and have it properly packaged, so it's useful to use a weaker assignment. (From OE-Core rev: cadd91655a336eb6d65ca43dc1231bbe5271e1cf) Signed-off-by: Ioan-Adrian Ratiu Signed-off-by: Richard Purdie

kernel.bbclass: Avoid iterating over KERNEL_IMAGETYPES twice

During deploy we iterate over KERNEL_IMAGETYPES twice, with no consumer of our changes in the interim. Collapse these two loops into one. (From OE-Core rev: 8d3139640ed4cd4e196dc2d1f6ae02d612fb9564) Signed-off-by: Alex Kiernan Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

kernel: Fix modules tarball generation with usrmerge

2018-09-22T22:52:12+00:00

When usrmerge is enabled the kernel modules aren't under /lib, but /usr/lib; ensure we fetch the modules from the correct location so we don't have a tarball which consists of a single symlink.

Revert "kernel.bbclass: do not deploy fitImage; kernel-fitimage.bbclass does that."

2018-09-22T22:52:12+00:00

This reverts commit 65cded55fa96b1ba72149a31689c081ac27af7f7. The fitImage deployed here is the one generated in kernel-fitimage.bbclass, whereas the one deployed by kernel-fitimage.bbclass is a raw image, so we need the one deployed here keeping.
