* kernel.bbclass: Create modules directory even if there is no modules installedHe Zhe2014-10-241-0/+1
| | | | | | | | | | | | | | | During kernel_do_install it needs to make symbol link at ${D}/lib/modules/${KERNEL_VERSION}/build, but there will not be ${D}/lib/modules/${KERNEL_VERSION} if there is no modules installed for current image, which will result in a build failure. 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.

* kernel.bbclass: enable a link for external module buildingNitin A Kamble2014-10-061-1/+2
| | | | | | | | | | | | | | | | | | Even though the kernel-dev package provides the required support for building external kernel modules on the target, some commonly used scripts and utilities fail as they are not finding the kernel module build support files at the desired location. Create the /lib/modules/<kernel-version>/build link on target pointing to the sources provided by the kernel-dev package, to fix the issue.

* kernel: don't copy .so.dbg files into kernel source installBruce Ashfield2014-07-251-1/+1
| | | | | | | | | | | | | | | In 3.16+ x86-64 kernel builds produce a vdso64.so.dbg file. If this file is copied into the kernel source install multiple QA failures are triggered. Specifically, this file triggers a debug package split that results in files installed but not shipped, and invalid .debug file errors. 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.)

| | | | | | | | | | | | | | | | | | | | 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.

* 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.

| | | | | | | | | | | | | | | | | | Compiling the Linux kernel requires binutils; kernel.bbclass uses INHIBIT_DEFAULT_DEPS so it had better depend on binutils explicitly. (The lack of this dependency isn't always a problem because binutils is required to build gcc-cross but if gcc-cross is reconstructed from the sstate cache then gcc-cross's dependency on binutils-cross is ignored due to being in the safe dependency list in setscene_depvalid.)

* kernel.bbclass: do_strip: allow recipes to strip the kernelMichel Thebeau2013-04-111-2/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow recipes to specify sections to be stripped from the kernel output using KERNEL_IMAGE_STRIP_EXTRA_SECTIONS. For example: KERNEL_IMAGE_STRIP_EXTRA_SECTIONS = ".comment .unwanted" The kernel output is stripped in place. Since the toolchain does not give indication when the specified sections are absent, we read the sections first and make this report by issuing a warning to the developer. The toolchain by default strips the image with the -s option (even when -s is not specified): -s --strip-all Remove all symbol and relocation information For example, these sections are always removed: .debug_aranges .debug_info .debug_abbrev .debug_line .debug_frame .debug_str .debug_loc .debug_ranges .symtab .strtab In addition to these, the sections listed in KERNEL_IMAGE_STRIP_EXTRA_SECTIONS will also be removed. Only stripping of vmlinux (elf) is supported at this time. A warning will be given if the image type is not vmlinux. Stripping the image could also be done in the kernel, but that would only work for linux-yocto based kernels, so it's not the route we decided to go.

* kernel.bbclass: do_sizecheck: update path to build image and do not deleteMichel Thebeau2013-04-081-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | do_sizecheck has a few issues especially with vmlinux image type. It breaks because KERNEL_OUTPUT is a path relative to ${B}. When do_sizecheck runs it does not find the file (because the working directory is elsewhere) and does not fail. Also, the image file referenced by KERNEL_OUTPUT may be a link. Finally, when do_sizecheck deletes the oversized kernel image it leaves the previously run do_compile task with inaccurate status. So, do the following: - specify that the working directory should be ${B} - use ls -L to reference to the real file, and ensure that the link file is created - keep the oversized image file so the status of do_compile is valid [YOCTO #3514] (From OE-Core rev: f0b19ddce3c92c5d06976cf73d4c4c480e053dff) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Michel Thebeau <michel.thebeau@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* kernel bbclass: return to original directory in do_deployChase Maupin2013-03-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * During the base kernel_do_deploy function the directory is changed to DEPLOYDIR in order to do some cleanup and symlinking. However, the directory is not changed back to the original starting directory ${S} at the end. For append functions this means that the starting directory is not ${S} as expected but instead ${DEPLOYDIR}. For functions like the do_deploy_append in recipes-kernel/linux/linux-dtb.inc there is an assumption that you are still in the source directory and not the DEPLOYDIR. Without this change the .dtb files are not copied because the check for the existence of ${DTS_FILE} which is a relative path from the ${S} directory fails. This means that the .dtb files are not copied into the deploy directory and subsequently the deploy/images directory. In the log.do_deploy file you will see lines like: Warning: arch/arm/boot/dts/xxxxx.dts is not available!

We avoid this behavior by generating a special depmodwrapper script.

* kernel: avoid copying unnecessary files during do_installMark Asselstine2013-02-011-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | kernel_do_install() populates $kerneldir with files needed to build external modules. To accomplish this there are several copy commands to get source from the kernel source tree and build trees after which a 'clean' is performed. Since we are copying from the build tree we get about 1G of .o and .cmd files copied over only to have them removed when we clean. This adds additional IO overhead as well as overhead caused by pseudo. By avoiding copying these files in the first place we get multiple gains: * avoid initial copy * avoid file deletes during clean * reduce pseudo overhead Additionally we are making use of cpio vs cp which tends to be significantly faster at performing copies. With these changes I observe a 15-30% decrease in the time to complete the do_install() operation on the kernel.
