* kernel: Pull out the linux.bin generationMarek Vasut2015-05-261-17/+23

* kernel: Rework do_uboot_mkimageMarek Vasut2015-05-261-11/+21
| | | | | | | | | | | | | | | | | | | | Rework the function so part it's internals can be re-used by fitImage image type. The name of the temporary file , linux.bin , is recycled a little more as it's now used for both the case where it is gzip compressed and where it is not. This should be fine, since the file is temporary and removed after the uImage was created anyway. There is no functional change here.

* kernel: Clean up KERNEL_IMAGETYPE_FOR_MAKEMarek Vasut2015-05-261-2/+4
| | | | | | | | | | | | | | | | | | | | Remove the lambda function setting KERNEL_IMAGETYPE_FOR_MAKE and instead set it in the anonymous python function. This also allows us to handle image types which are not supported directly by kernel, but require some other kernel target to be built. This is the case for example with the fitImage, which is the uImage successor. There is no functional change.

* kernel/rm_work: Improve interactionRichard Purdie2015-05-151-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* kernel.bbclass: Fix race conditionEd Bartosh2015-05-071-1/+1
| | | | | | | | | | | | | | | | | Race condition between do_compile_kernelmodules and do_shared_workdir tasks occurs when do_compile_kernelmodules changes files in include/generated/* while do_shared_workdir tries to copy them to shared working directory.

* kernel: Fix depmod for multilibRichard Purdie2015-01-291-15/+11
| | | | | | | | | | | | Using populate_sysroot for this data was a nice idea but flawed as it doesn't work in multilib builds. Instead we can use PKGDATA_DIR since this is consistent over multilib builds. It also turns out to be slightly neater code too. Hopefully this resolves the problem once and for all.

* kernel/image/depmodwrapper: Fixups for depmodRichard Purdie2015-01-231-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* kernel: move source and build output to work-sharedBruce Ashfield2015-01-161-12/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* kernel: Fix non linux-yocto buildsRichard Purdie2014-12-211-4/+25
| | | | | | | | | | | | | | | | | | | | 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.

* kernel: Rearrange for 1.8Richard Purdie2014-12-211-88/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 1.8 we want to streamline the kernel build process. Basically we currently have multiple copies of the kernel source floating around and the copying/compression/decompression is painful. Lets assume we have a kernel source per machine since in most cases this is true (and we have a sysroot per machine anyway). Basically, instead of extracting a source into WORKDIR, then copying to a sysroot, we now set S to point straight at STAGING_DIR_KERNEL. Anything using kernel source can then just point at it and use: do_configure[depends] += "virtual/kernel:do_patch" to depend on the kernel source being present. Note this is different behaviour to DEPENDS += "virtual/kernel" which equates to do_configure[depends] += "virtual/kernel:do_populate_sysroot". Once we do this, we no longer need the copy operation in do_populate_sysroot, in fact there is nothing to do there (yay). The remaining part of the challenge is to kill off the horrible do_install. This patch splits it off to a different class, the idea here is to have a separate recipe which depends on the virtual/kernel:do_patch and just installs and packages the source needed to build modules on target into a specific package. Right now this code is proof of concept. It builds kernels and kernel modules. perf blows up in do_package with issues on finding the kernel version which can probably be fixed by adding back the right bit of do_install, and adding a dependency of do_package[depends] += "virtual/kernel:do_install" to perf. The whole thing needs a good write up, the corner cases testing and probably a good dose of cleanup to the remaining code.

* kernel: stop using -exec rm for deleting filesBruce Ashfield2014-02-111-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removing files from the source tree via find, exec and rm is not the most efficient operation, due to (among other things) the many forked processes. If we use -delete, it saves a significant amount of time. But -delete does not work with -prune (since it forces -depth). To maintain the lib, tools and scripts source files, we can hide them temporarily, skip their hidden directories and then finally restore them. Time for install before this change: real 2m48.563s user 0m35.220s sys 0m33.036s Time for install after this change: real 1m21.301s user 0m33.160s sys 0m28.388s We could further speed this up by using inline perl to delete the files, but that complexity is avoided for now.

* kernel.bbclass: Fix empty modules directory QA issueNathan Rossi2014-02-021-0/+2
| | | | | | | | | | | | | | | | | | | | | If a kernel is built without any external modules (aka no CONFIG_*=m), then during a modules_install of the kernel an empty directory is created at /lib/modules/${KERNEL_VERIONS}/kernel. This is behaviour of the kernel infrastructure, the directory would normally be populated with the modules that were built. However because of the expectations of kernel-modules-split, no packages are created when there are no modules and an empty directory lingers. This raises QA issues as warning or errors (depending on the distro). The following patch changes the kernel_do_install task to check if the directory is empty and if so removes it.

* kernel.bbclass: Stop bundle_initramfs thwarting sstate cache and fix raceMike Crowe2013-11-241-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | The new do_bundle_initramfs task introduced in 609d5a9ab9e58bb1c2bcc2145399fbc8b701b85a defeats using the sstate cache. The kernel is resurrected from the sstate cache but ends up being built again since do_bundle_initramfs depends on do_compile. The task is no longer nostamp to avoid causing unnecessary rebuilds. The sstate checksum stamps should know when to rebuild. The task now runs before do_deploy and part of the work has been moved to do_deploy where it now writes to ${DEPLOYDIR} rather than ${DEPLOY_DIR_IMAGE} so that the files end up in sstate. The task can also race against do_install since both call into the kernel build system. This is fixed by making do_bundle_initramfs run after do_install (which therefore also fixes the problem that 3baa63b4d588c3262254528b406ede265dd117bf was addressing.)

| | | | | | | | | | | | | | | | | | | | Whilst the comment says we can't do this, its incorrect, install operates on WORKDIR and its hard for different parts of WORKDIR to be on different filesystems. Hardlinking instead of copying is therefore a nice performance gain. Also, completely skip the Documentation directory (adding a dummy Makefile to keep make happy) and tweak the other cp commands to link since if we don't we'd get "this is the same file" type errors from cp for some kernel versions. For do_install on linux-yocto, this takes it from 227s -> 84s.

For the kernel source in the staging dir, these scripts have been removed to avoid mixing archiectures when packaging kernel-dev (among other things). Rather than further complicate the kernel's install rule, or its packaging, we can restore the scripts by building them in the kernel staging directory after the sstate is installed, making them available to packages that need them.

| | | | | | | | | | | | | | | | | | | | Activating the INITRAMFS_TASK can cause circular dependencies, but that is up to the end user to resolve in recipes.

This was a subtle regression introduced by: 609d5a9ab (kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency and bundling).

* kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency and ↵Jason Wessel2013-09-061-12/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bundling This patch aims to fix the following two cases for the INITRAMFS generation. 1) Allow an image recipe to specify a paired INITRAMFS recipe such as core-image-minimal-initramfs. This allows building a base image which always generates the needed initramfs image in one step 2) Allow building a single binary which contains a kernel and the initramfs. A key requirement of the initramfs is to be able to add kernel modules. The current implementation of the INITRAMFS_IMAGE variable has a circular dependency when using kernel modules in the initramfs image.bb file that is caused by kernel.bbclass trying to build the initramfs before the kernel's do_install rule. The solution for this problem is to have the kernel's do_bundle_initramfs_image task depend on the do_rootfs from the INITRAMFS_IMAGE and not some intermediate point. The image.bbclass will also sets up dependencies to make the initramfs creation task run last. The code to bundle the kernel and initramfs together has been added. At a high level, all it is doing is invoking a second compilation of the kernel but changing the value of CONFIG_INITRAMFS_SOURCE to point to the generated initramfs from the image recipe.
