2017-01-11kernel.bbclass: do not copy bundled initramfs to /bootAndreas Oberritter1
These files cause warnings because they don't get packaged, now that they don't land in kernel-vmlinux anymore.

With multiple kernel images enabled starting with 'vmlinux', e.g. vmlinux.gz and vmlinux.bin, all files landed inside the kernel-vmlinux package. On top of that, even initramfs images were included, e.g. vmlinux.gz-initramfs-*.

2016-07-25kernel.bbclass: explicitly set workdir in do_bundle_initramfsAndré Draszik1
bitbake rev 67a7b8b02 "build: don't use $B as the default cwd for functions" (included in current bitbake master) breaks the assumption that do_bundle_initramfs runs inside the build directory. This causes kernel_do_compile() as called from within do_bundle_initramfs() to fail, as the former is not being executed from the correct directory anymore. (Note that kernel_do_compile() as called from bitbake directly doesn't suffer from that problem, as it inherits the workdir from base_do_compile() in that case.) Set workdir explicitly.

2016-07-01classes/kernel: fix symlink logic when bundling initramfs imagesAndré Draszik1
If linkpath points to the a file in KERNEL_OUTPUT_DIR, rather than outside, then symlink creation for the bundled initramfs image files fails. This is because in that case $linkpath.initramfs and $realpath.initramfs are in the same directory, KERNEL_OUTPUT_DIR, and hence are the same. Since we just created $realpath.initramfs, creating a symlink with the same name will fail. Given that $linkpath is not necessarily the same as the kernel image type, just removing this symlink creation is not the right thing to do, as in that case kernel_do_deploy() wouldn't find the bundled file. What we really want is a symlink from the name of the initramfs-bundled kernel image type to the real initramfs-bundled kernel image, as that is what is actually used later in do_deploy(). This brings the code path for when $KERNEL_OUTPUT_DIR/$type is a symlink in line with when it is not.

2016-07-01classes/kernel: fix symlink creation in DEPLOYDIR for bundled initramfsAndré Draszik1
If multiple kernel image types have been specified, only the very first one would receive a symlink in DEPLOYDIR. The reason is that we're looping over the list of image types and check if a bundled initramfs images exists using a relative path. As part of the loop we're changing the current directory, hence all additional iterations fail to see the files we're looking for, and hence no symlinks are being created.

2016-02-04Revert "kernel/kernel-arch: Explicitly mapping between i386/x86_64 and x86 ↵Ioan-Adrian Ratiu1
for kernel ARCH" This reverts commit 8d310b24927d0f348fb431895f0583733db2aad0. That commit completely breaks KBUILD_DEFCONFIG because it relies on $ARCH to match between the target OE arch and the kernel subdirectory containing the defconfigs. In the kernel all defconfigs for everything x86-based (including x86_64) is stored in dir arch/x86/configs/ kernel-yocto.bbclass correctly searches for all the defconfigs inside ${S}/arch/${ARCH}/configs/${KBUILD_DEFCONFIG} Commit 8d310b249 makes it search in wrong places and _only_ if you define TARGET_ARCH = "athlon" will it search x86 which is nonsensical. The commit further adds an if clause to hack the mungled kernel arches back to their original values (ugh) in do_shared_workdir which is run after do compile, but of course the build breaks before that in do_kernel_metadata because of the KBUILD_DEFCONFIG mentioned above (so that hack is useless). Please fix that corner case bug in another way which does not completely screw up the kernel arch mapping & defconfig logic. If 64bit configs are generated in the kernel for 32bit machines because the host is asked, then it it a bug in the kernel, it is of no use to hack around it in OE.

kernel ARCH For a bare-bone kernel recipe which specifies 32 bit x86 target, a 64 bit .config will be generated from do_configure task when building 32-bit qemux86, once all of these conditions are true: * arch of host is x86_64 * kernel source tree used in build has commit ffee0de41 which actually chooses i386 or x86_64 defconfig by asking host when ARCH is "x86" (arch/x86/Makefile) * bare-bone kernel recipe inherits directly from kernel without other special treatments. Build will fail because of the mismatched kernel architecture. The patch sets ARCH i386 or x86_64 explicitly to configure task to avoid this host contamination. Kernel artifact is also changed so that it can map i386 and x64 back to arch/x86 when needed.

2015-05-15kernel/rm_work: Improve interactionRichard Purdie1
The do_shared_workdir task does leave behind the necessary information in shared-work after it completes. We don't make this a "full" sstate task however since that means tarring up and copying what is usually a large amount of data which would be better extracted straight from the original SCM. The issue with rm_work occurs since it removes the do_shared_workdir stamp meaning subsequent builds will add it back if they need to touch any kernel modules for example. This ends up triggering a near enough complete kernerl rebuild since if configure reruns, populate_sysroot has to rerun. This change promotes the task to have a "setscene" variant but it doesn't use any of the sstate class lifting to generate the sstate file. The sstate function will therefore never get called since the sstate object will never exist. We can add the task to the list of tasks rm_work promotes to a setscene variant and unwanted rebuilds of the kernel should be avoided.

With the rpm package backend enabled, running: bitbake <image> bitbake virtual/kernel -c clean bitbake <image> -c rootfs -f results in an image with incorrect kernel module dependency information. The problem is that the System.map and kernel-abiversion files are needed for depmod and after the recent kernel changes, these are no longer in sstate. Its reasonable to require the kernel to unpack/build if you're about to build a module against it. It is not reasonable to require this just to build a rootfs. Therefore stash the needed files specifically for depmod. Also fix some STAGING_KERNEL_DIR references which were incorrect, found whilst sorting through his change.

2015-01-16kernel: move source and build output to work-sharedBruce Ashfield1
commit 3b3f7e785e279 [kernel: Rearrange for 1.8] began the process of moving the kernel source and build artefacts out of sstate control and into a shared location. This changed triggered some workflow issues, as well as bugs related to the kernel source containing build output, and hence being dirty and breaking kernel rebuilds. To solve these issues, and to make it clear that the kernel is not under sstate control, we move the source and build outputs to: work-shared/MACHINE/kernel-source work-shared/MACHINE/kernel-build-artifacts Where kernel-build-artifacts is the kernel build output and kernel-source is kept "pristine". The build-artifacts contain everything that is required to build external modules against the kernel source, and includes the defconfig, the kernel-abiversion, System.map files and output from "make scripts". External module builds should either pass O= on the command line, or set KBUILD_OUTPUT to point to the build-artifacts. module-base.bbclass takes care of setting KBUILD_OUTPUT, so most existing external module recipes are transparently adapted to the new source/build layout. recipes that depend on the kernel source must have a depedency on the do_shared_workdir task: do_configure[depends] += "virtual/kernel:do_shared_workdir" With this dependency added, the STAGING_KERNEL_DIR will be populated and available to the rest of the build.

2014-12-21kernel: Fix non linux-yocto buildsRichard Purdie1
After the recent kernel changes, non linux-yocto builds stopped working properly for two reasons: a) ${S} was being reset to ${WORKDIR}/git for example and STAGING_KERNEL_DIR did not contain the source b) Most builds were using ${B} == ${S} This patch adds a fixup to the unpack function to handle the case where ${S} != ${STAGING_KERNEL_DIR} and also set up the infrastrcture so that B != S for kernel builds from now on. The kernel build system is one of the best for supporting this and there is no good reason not to take advantage of it. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-12-20kernel: Clean ${S} before unpackRichard Purdie1
Currently unpack just forces sources over the current files. This change ensures ${S} is cleaned out before sources are unpacked. This resolves issues seen when upgrading to the new kernel class changes. Ultimately, this should probably move to base.bbclass but one step at a time, this solves an immediate problem blocking the other patches from merging.
