kernel.bbclass: Add force flag to rm calls

2023-09-30T19:43:59+00:00

The latest 6.5 kernels do not appear to create the source file in ${D}${nonarch_base_libdir}/modules/${KERNEL_VERSION}/source so the recipe errors out when trying to remove it. Simple fix is to add the -f (force) flag to the call.

kernel: Fix path comparison in kernel staging dir symlinking

2023-08-26T14:24:02+00:00

Due to an oversight in the do_symlink_kernsrc function, the path comparison between "S" and "STAGING_KERNEL_DIR" is broken. The code obtains both variables, but modifies the local copy of "S" before comparing them, causing the comparison to always return false. This can cause the build to fail when the EXTERNALSRC flag is enabled, since the code will try to create a symlink even if one already exists. This patch resolves the issue by comparing the variables before they are modified.

kernel: add missing path to search for debug files

2023-08-02T14:47:13+00:00

Since explicit debug package creation via ${KERNEL_PACKAGE_NAME}-dbg has been added to kernel, it has to cover all PACKAGE_DEBUG_SPLIT_STYLE options. For ex. when the variable "debug-file-directory" package search path has to be set explicitly, otherwise it will not find any files.

kernel: don't force PAHOLE=false

2023-06-23T14:16:41+00:00

If a specific kernel provider or configuration wants to enable BTF and pahole analysis, it isn't currently possible due to the explicit definition to false in the base kernel build arguments. pahole is now detected by the kernel built itself, so unless pahole-native is enabled, the result is the same. If a kernel does require an explicit disable of pahole, it is better to carry PAHOLE=false in those specific recipes.

kernel-devicetree: make shell scripts posix compliant

2023-06-02T02:24:07+00:00

Use the notation suggested by Martin Jansa to avoid a bashism. Also switch KERNEL_DTBVENDORED to the more common 0/1 notation instead of true/false.

kernel-devicetree: allow specification of dtb directory

2023-06-02T02:24:07+00:00

Fedora/Redhat and Arch are somewhat standardized on their dtb directory structure. Let's add some flags to configure yocto to mimic that behavior. Add the following variables to the kernel class: - KERNEL_DTBDEST (controls the destination directory for dtbs) - KERNEL_DTBVENDORED (controls if vendor subdirectories are to be respected) Currently KERNEL_DTBDEST is expected to be a subdir of KERNEL_IMAGEDEST and KERNEL_DTBVENDORED is expected to be "true"/"false". This only applies to the package directory structure. The deploydir structure is purposely left untouched for compatibility with existing recipes. By default this is configured to behave the same as the current recipe and produce a flat dtb directory at KERNEL_IMAGEDEST.

kernel: improve initramfs bundle processing time

2023-05-12T14:04:52+00:00

This is a partial fix for bugzilla 15059 [https://bugzilla.yoctoproject.org/show_bug.cgi?id=15059] It has been noted by several people that when an initramfs is bundled: - a lot of the kernel is rebuilt - it takes a really long time When looking at the logs, the second kernel compilation (that performs the bundle) is not using the parallel make settings, and builds with -j1. We are already explicitly passing PARALLEL_MAKE when building kernel modules, and by extending that explicit use to the main kernel compilation, we ensure that we always get a parallel build. Build times chnaged from more than 30 minutes for the bundle, to 3 minutes in local testing. The question of whether or not too much is rebuilding during the bundle step is still an open question, but with this tweak, at least the build time is back in the realm of acceptable.

linux: inherit pkgconfig in kernel.bbclass

2023-03-20T17:20:44+00:00

pkgconfig is being required to find dependencies for building kernel native tools, move "inherit pkgconfig" to kernel.bbclass so BSP kernel recipes can also benefit from it.

kernel/linux-kernel-base: Fix kernel build artefact determinism issues

2023-02-15T21:46:56+00:00

With the 6.1 kernel we've seen reproducibility/determinism issues where the kernel seems to rebuild headers referencing the hostname or local user. kernel-devsrc building after the kernel seemed to trigger it in some cases. Moving the definitions to the bbclass used by all the kernel recipe code including kernel-devsrc seems to be the best way to ensure this doesn't happen.
