kernel: Fix interaction when packaging disabled

2021-07-10T21:46:19+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.

kernel.bbclass: fix do_sizecheck() comparison

2021-06-19T15:59:29+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).

kernel.bbclass: Remove do_install[prefunc] no longer needed

2021-05-13T21:10:06+00:00

Prior work has refactored the do_install task multiple times, and any references to PKGV and PKGR (even indirect ones) have been removed.

kernel.bbclass: Configuration for environment with HOSTCXX

2021-05-04T21:57:55+00:00

When compiling xilinx-zynq board linux-kernel-dev(v5.8) if "GCC_PLUGINS=y", The following error will appear: "HOSTCXX -fPIC scripts/gcc-plugins/arm_ssp_per_task_plugin.o fatal error: gmp.h: No such file or directory" the GCC_PLUGINS depend on return result of gcc-plugin.sh execution however in gcc-plugin.sh use HOSTCC to detect the feature of GNU extension of gcc, this will result that HOSTCC can compile the file successfully, but HOSTCXX is used in the actual compilation process.

kernel.bbclass: fix deployment for initramfs images

2021-02-10T23:55:53+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: set COMPATIBLE_HOST to *-linux

2021-01-01T11:55:35+00:00

The target system triple contains whether the target is Linux or not, so use it to avoid situations where you can attempt to build a kernel for systems which don't support Linux.

kernel: Set proper LD in KERNEL_KCONFIG_COMMAND

2020-12-09T23:49:01+00:00

With 'ld-is-gold' and linux kernel 5.4 or later, menuconfig task for kernel recipes will fail with: $ bitbake -c menuconfig virtual/kernel ... scripts/kconfig/mconf Kconfig scripts/Kconfig.include:43: gold linker 'x86_64-poky-linux-ld' not supported /OE/build/tmp/work-shared/qemux86-64/kernel-source/scripts/kconfig/Makefile:29: recipe for target 'menuconfig' failed make[2]: *** [menuconfig] Error 1 /OE/build/tmp/work-shared/qemux86-64/kernel-source/Makefile:606: recipe for target 'menuconfig' failed make[1]: *** [menuconfig] Error 2 /OE/build/tmp/work-shared/qemux86-64/kernel-source/Makefile:185: recipe for target '__sub-make' failed make: *** [__sub-make] Error 2 Command failed. This is because that the KERNEL_LD variable already set in kernel-arch.bbclass isn't used by do_menuconfig function of cml1.bbclass. To fix this issue specify LD variable while calling the kernel menuconfig command through KERNEL_KCONFIG_COMMAND.

kernel: relocate copy of module.lds to module compilation task

2020-12-09T23:49:00+00:00

There were two copies of this patch floating around, and the merged variant has the copy in the wrong place. module.lds is only created during modules_prepare, and that target is not invoked during our main build of the kernel. We aren't about to change the kernel build (there's no need), so we move the copy into the compile_kernelmodules task. After that runs, we have module.lds availble to copy. This has been tested against clean kernel + out of tree module builds, and the dependencies are correct that the file is copied before the out of tree module build starts.

kernel: provide module.lds for out of tree builds in v5.10+

2020-12-09T23:49:00+00:00

The upstream commit 596b0474d3d [kbuild: preprocess module linker script], adds a dependency on module.lds for external module building. Since module.lds is generated as part of 'modules_prepare', we must make it available with the other kernel artifacts in the kernel shared workdir, otherwise out of tree builds fail. This fixes errors like: | make[4]: *** No rule to make target 'scripts/module.lds', needed by 'build/tmp/work/qemuarm64-poky-linux/cryptodev-module/1.11-r0/git/cryptodev.ko'. Stop. | make[4]: *** Waiting for unfinished jobs.... We also ensure that kernel-devsrc has a copy to support on target module builds that are often prepared with 'make scripts prepare'. Those targets won't regenerate it, so the build fails. If 'make modules_prepare' is used, the file will be regenerated and overwrite our copy (as expected).
