kernel: drop unnecessary True options from calls to getVar

2018-01-19T12:37:13+00:00

The older style calls (plus a bashism in kernel.bbclass, fixed separately) were introduced via the recent change to add support for multiple kernel packages: http://git.openembedded.org/openembedded-core/commit/?id=6c8c899849d101fd1b86aad0b8eed05c7c785924 (From OE-Core rev: e660ef68de3b3891a26ed6e10d96dc4efaf03ffc) Signed-off-by: Andre McCurdy Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

kernel: Add support for multiple kernel packages

2018-01-02T17:24:37+00:00

Some distros may want to provide alternate kernel "flavors" via feeds or within bootable images. For example, readily available builds which provide certain diagnostic features can enable developers and testers to more quickly resolve issues by avoiding lengthy kernel builds. This change allows for building multiple flavors of the kernel and module packages by templatizing kernel package names via a new KERNEL_PACKAGE_NAME variable in kernel.bbclass. It defaults to the old name of "kernel", but can be overridden by certain recipes providing alternate kernel flavors. To maintain compatibility, recipes providing alternate kernel flavors cannot be the "preferred provider" for virtual/kernel. This is because OE puts the preferred provider's build and source at "tmp-glibc/work-shared/$MACHINE/kernel-build-artifacts/" and "tmp-glibc/work-shared/$MACHINE/kernel-source/" instead of "tmp-glibc/work/*/$PN/" like other recipes. Therefore, recipes using the default KERNEL_PACKAGE_NAME="kernel" follows the old semantics -- build in the old location and may be preferred provider -- while recipes using all other KERNEL_PACKAGE_NAME's build from the normal WORKDIR and don't provide "virtual/kernel". Testing: 1. Add `KERNEL_PACKAGE_NAME_pn-linux-yocto-tiny = "tiny-linux"` to local.conf so that linux-yocto-tiny may build alongside the main kernel (linux-yocto). 2. `bitbake linux-yocto linux-yocto-tiny` to build both kernel flavors. 3. Verified image and modules IPKs exist for both: tmp-glibc/deploy/ipk/qemux86/kernel-* for linux-yocto tmp-glibc/deploy/ipk/qemux86/tiny-linux* for linux-yocto-tiny 4. Verified linux-yocto is the "preferred provider", and was built in shared directory: tmp-glibc/work-shared/qemux86/kernel-* 5. Add `CORE_IMAGE_BASE_INSTALL_append_pn-core-image-base = "tiny-linux"` to local.conf to install both kernel flavors in core-image-base. 6. `bitbake core-image-base` to build an image. 7. Verified image contains two bzImage's under /boot/, with "yocto-standard" (linux-yocto recipe) selected to boot via symlink.

Revert "kernel-module-split: rrecommend kernel-image instead of rdepend"

2017-09-12T22:55:28+00:00

This reverts commit e0ed52c51464855e9a6a37ea49df7efde7e91076. Commit e0ed52c514 ('kernel-module-split: rrecommend kernel-image instead of rdepend') changed kernel modules to rrecommend kernel-image instead of rdepend on kernel. This broke existing setups, where the kernel is omitted by setting RDEPEND_kernel-base = "". Revert the patch, as the existing way of omitting kernel-image in images works just fine.

kernel-module-split: rrecommend kernel-image instead of rdepend

2017-08-23T07:47:02+00:00

Hard depending on the kernel makes it impossible to install kernel modules without getting the kernel image installed too. This is inconvenient in e.g. initramdisks, where the kernel is loaded from outside the initramdisk. Making the kernel modules rrecommend kernel-image- instead of rdepending on it, makes it possible to install kernel modules without the kernel image by setting "kernel-image" in BAD_RECOMMENDATIONS.

meta: Fix return value checks from subprocess.call()'s

2017-06-28T19:55:08+00:00

Python function subprocess.call() returns the return value of the executed process. If return values are not checked, errors may go unnoticed and bad things can happen. Change all callers of subprocess.call() which do not check for the return value to use subprocess.check_call() which raises CalledProcessError if the subprocess returns with non-zero value. https://docs.python.org/2/library/subprocess.html#using-the-subprocess-module All users of the function were found with: $ git grep "subprocess\.call" | \ egrep -v 'if.*subprocess\.call|=\ +subprocess\.call|return.*subprocess\.call' Tested similar patch on top of yocto jethro. Only compile tested core-image-minimal on poky master branch.

The OVS fails to function and the kernel modules cannot be found by any of the kernel tools such as depmod because they are installed into the wrong directory in multilib 64bit/32bit bulids.
