* kernel: Clean DEPLOYDIR before do_deploy runsRichard Purdie2016-01-261-0/+1
| | | | | | | | | | | | If we don't do this, the deploy sstate object contains an every increasing number of modules tarballs and kernel images, one per execution of "-c deploy -f". Cleaning the directory before we start makes things much tidier. (From OE-Core rev: 3ac195bbd4ced24e6a132cfbe5e175b95fc4664b) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* kernel-yocto.bbclass: move do_kernel_link_vmlinux() into kernel.bbclassAndre McCurdy2016-01-181-0/+12
| | | | | | | | | | | | | | | | Move do_kernel_link_vmlinux() from kernel-yocto.bbclass into kernel.bbclass so that it's available to any kernel recipe. Note that the task is not enabled by default in kernel-yocto.bbclass, so don't enable by default in kernel.bbclass either.

* kernel/kernel-arch: Explicitly mapping between i386/x86_64 and x86 for ↵Jianxun Zhang2016-01-151-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | If externalsrc is enabled the 'do_unpack' task is run if the recipe has some local source files. In the case of kernel recipe this caused the (externalsrc) source tree to be moved/symlinked. This patch prevents the behaviour, making sure the source tree is not moved around when externalsrc is enabled. Instead of moving the source tree, STAGING_KERNEL_DIR will be a symlink to it.

* 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.

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: 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.

Add "mkdir -p ${D}/lib/modules/${KERNEL_VERSION}" here to avoid this failure and the need of similar changes in other scripts that also expect it to exist.

By ensuring that .so files are not copied, we avoid this incorrect split with no impact on future build phases.

* kernel.bbclass, base.bbclass: Fix support for old kernel configurationOtavio Salvador2014-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | This solves a regression introduced by OE-Core:9b75f6a (kernel: use oldnoconfig before yes '' | make oldconfig). The original oe_runmake explicitly calls 'die' command in case of failure so the fallback code never runs. The fallback code needs to handle the oe_runmake return code to call the backward compatible callback so we introduced a new command called oe_runmake_call which is used by oe_runmake. This does not change the functional behaviour of oe_runmake so it avoids any change except for the code which does need to handle the oe_runmake exit 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.)
