kernel: Use consistent make flags for menuconfig

2022-09-16T16:53:22+00:00

We're currently only passing in a subset of the kernel make flags to menuconfig. Fix this to be consistent with all the other kernel operations since these are becomming increasingly reliant on host compilers and flags and target toolchains as well.

kernel: Always set CC and LD for the kernel build

2022-09-16T16:53:22+00:00

It as been bothering me a bit that we don't set CC and LD consistently for the kernel make calls and this can lead to interesting bugs as the kernel increases in complexity. Add them to EXTRA_OEMAKE so they're always passed in. This makes everything slightly more consistent and less likely to break in future.

kernel.bbclass: Fix the do_strip() malfunction

2022-04-12T08:43:43+00:00

The BB variable can't be referenced directly in a python function, this misusage of the variable reference causes strip function to be always skipped.

kernel.bbclass: avoid config changes based on the availability of pahole

2022-03-26T09:33:32+00:00

CONFIG_PAHOLE_HAS_SPLIT_BTF shows up in the config only when pahole is installed on the host system. As a result, the config changes depending on whether pahole is installed or not. Set PAHOLE=false to ensure that it is never found. If this is actually needed in the future, then we can add an option for it and create a host package for pahole.

kernel: make kernel-base recommend kernel-image, not depend

2022-02-21T21:53:52+00:00

As kernel modules depend on the base kernel package, and the base kernel recipe depends on the kernel image, it's impossible to build file system images which contain kernel modules but not the kernel itself, such as an initramfs. Change the RDEPENDS to RRECOMMENDS so that the disk images can set PACKAGE_EXCLUDE = "kernel-image-*" to remove the kernel.

kernel.bbclass: Allow initramfs to be built from a separate multiconfig

2022-01-26T06:27:00+00:00

There may be a case where we want to build an initramfs image that doesnt inherit the same DISTRO_FEATURES (or others) from the main image being built. For example we may want our initramfs not to inherit a certain conf or feature, say we want to use musl for a smaller footprint, but if we are using TCLIBC=glibc for our DISTRO (and inherently our main image), the initramfs image would inherit that conf and be forced to use glibc, growing in size as a side effect, currently avoiding this is not supported. Allow the kernel class to create a multiconfig dependency (mcdepends) vs depends for do_bundle_initramfs and define our INITRAMFS_IMAGE from a separate multiconfig via two new variables: INITRAMFS_MULTICONFIG and INITRAMFS_DEPLOY_DIR_IMAGE which define the multiconfig where the initramfs image should be coming from and its deploy directory respectively, these two keep a default definition which preserves current behavior (do_bundle_initramfs uses depends). Example usage: - Create and use multiconfig initramfscfg.conf and set TCLIBC=musl there, along with its TMPDIR. - Add the following to our DISTRO.conf: INITRAMFS_MULTICONFIG = "initramfscfg" and set INITRAMFS_DEPLOY_DIR_IMAGE to the DEPLOY_DIR_IMAGE of the initramfscfg multiconfig (hence our main kernel will be able to grab it from there and bundle it). This will result in our musl based initramfs bundled in our main kernel and our main image to be glibc based.

kernel.bbclass: use common strip()

2022-01-13T13:57:26+00:00

Re-use the runstrip() code from oe.packaging, for the kernel stripping process. Since runstrip() is python the kernel do_strip() need to be converted to Python also. The stripped kernel image will be used for deployment in do_deploy(). This will allow the package.bbclass to split an unstripped kernel binary for the debug information and extended packagedata. The extended package data is used by create-spdx. (From OE-Core rev: e8d9caede5f08154ca615fdaba676b7a4ae05b01) Signed-off-by: Saul Wold Signed-off-by: Richard Purdie
