kernel.bbclass: remove unnecessary dead code

2021-09-28T16:55:04+00:00

The grep pattern seems to have been wrong ever since we stopped adding the -ffile-prefix-map via a patch in commit 20aea61385e, because the actual upstream gcc produces -ffile-prefix-map== and not -ffile-prefix-map= Besides, these *-prefix-map options are already used when building the kernel due to the setting of KERNEL_CC, and the kernel build system itself also probes for and uses at least -fmacro-prefix-map (hence taking care of __FILE__ etc., but not necessarily things that go in .debug_info sections).

base/kernel: Support zstd-compressed squashfs and cpio initramfs

2021-09-01T13:06:17+00:00

Enable zstd PACKAGECONFIG knob for squashfs-tools and add support for zstd compressed initramfs and squashfs. (From OE-Core rev: fa146049eec5f9730781830270cc9dc55a2146f7) Signed-off-by: Zoltán Böszörményi Signed-off-by: Richard Purdie

kernel: Use unexpanded EXTENDPKGV

2021-09-01T11:07:38+00:00

EXTENDPKGV can contain AUTOINC so use an expanded form in the variables allowing for later expansion during packaging to avoid race issues over the variable and the build failures that can result. (From OE-Core rev: 1f93d2426d22c74893e8daec9bb939133c5737c2) Signed-off-by: Richard Purdie

kernel.bbclass: Use full versions for inter-package dependencies

2021-08-27T10:54:34+00:00

If the kernel configuration enables module signing but no key is provided, then the kernel generates one during the kernel build. The current runtime-dependency references (with only package names without full versions) allow mixed package installations from different rebuilds of the same kernel version. This creates an issue because then the modules either don't work or taint the kernel. Tighten RDEPENDS with the full package version, i.e. use (= ${EXTENDPKGV}) markers for inter-package dependencies. The kernel will pull in the kernel-modules subpackage of the same exact version automatically if KERNEL_SPLIT_MODULES="0" is set. Otherwise the situation is the same as with the old default with one subpackage per kernel module where they have to be upgraded manually.

Allow opt-out of split kernel modules

2021-08-27T10:54:33+00:00

For some use cases, a monolithic kernel-modules package containing all modules built from the kernel sources may be preferred. For one, download time is shorter and installation time is faster. Set KERNEL_SPLIT_MODULES="0" for this in. The default is one subpackage per module. Also, adapt kernel.bbclass to KERNEL_SPLIT_MODULES != "1" case Extra RDEPENDS and other inter-package references are needed in this case.

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

kernel: Fix interaction when packaging disabled

2021-06-27T21:51:05+00:00

When packaging is disabled using the nopackages class, ensure we don't add to PACKAGES. This fixes builds where we have an unpackaged kernel alongside a packaged kernel. (From OE-Core rev: 2522daf22e2c27dd9c7926feda0345978217c6c3) Signed-off-by: Richard Purdie

kernel.bbclass: fix do_sizecheck() comparison

2021-06-14T14:05:11+00:00

The routine do_sizecheck() was historically needed by legacy devices with limited flash memory. The lowest extreme is probably with Zaurus collie having exactly 1024*1024 = 1048576 bytes for the kernel partition. In the years the KERNEL_IMAGE_MAXSIZE has been converted to kilobytes thus rounded so we have now KERNEL_IMAGE_MAXSIZE_collie = "1024". The effect is that now the check fails because we hit curiously this | WARNING: This kernel zImage (size=1024(K) > 1024(K)) is too big for... even though zImage is 1047288 bytes (kernel + kexecboot-klibc-initramfs). Fix this case using test -gt (greater) instead of -ge (greater or equal). (From OE-Core rev: 254ca956d63b4ce6aa294213b60bb943f9f3a9e6) Signed-off-by: Andrea Adami Signed-off-by: Richard Purdie

kernel.bbclass: fix deployment for initramfs images

2021-01-30T10:41:04+00:00

The do_bundle_initramfs() only processes kernel image types that are found in KERNEL_IMAGETYPE_FOR_MAKE whereas the build system can generate other types that are not directly supported by the kernel build system. In which case when we come to the deploy phase not all the images mentioned in KERNEL_IMAGETYPES would have a respective initramfs bundled image. An example is using vmlinux.gz in KERNEL_IMAGETYPES and enabling initramfs and then we see install: cannot stat 'arch/arm64/boot/vmlinux.gz.initramfs': No such file or directory So we align the deploy phase with bundle initramfs phase and pick up relevant initramfs bundled images using KERNEL_IMAGETYPE_FOR_MAKE instead of KERNEL_IMAGETYPES.

kernel: skip installing fitImage when using Initramfs bundles

2021-01-20T00:45:05+00:00

When including an initramfs bundle inside a FIT image, the fitImage is created after the install task by do_assemble_fitimage_initramfs. This happens after the generation of the initramfs bundle (done by do_bundle_initramfs). So, at the level of the install task we should not try to install the fitImage. The fitImage is still not generated yet. After the generation of the fitImage, the deploy task copies the fitImage from the build directory to the deploy folder.
