2013-05-24kernel.bbclass: Add dependency on binutilsMike Crowe
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.)

Currently the names used for the kernel in deploy will contain "AUTOINC" instead of the final incremental numbering.

2013-04-11kernel.bbclass: do_strip: allow recipes to strip the kernelMichel Thebeau
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.

2013-04-08kernel.bbclass: do_sizecheck: update path to build image and do not deleteMichel Thebeau
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] 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>
2013-03-18kernel bbclass: return to original directory in do_deployChase Maupin
* 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!

2013-03-01Add KERNEL_EXTRA_ARGS parameterWolfgang Denk
With recent kernel versions, some ARM configurations need may fail to build with errors like this: multiple load addresses: 0x80008000 0x80008000 This is incompatible with uImages Specify LOADADDR on the commandline to build an uImage We cannot pass this information in EXTRA_OEMAKE, as "meta/classes/kernel.bbclass" explicitly ignores all EXTRA_OEMAKE settings. So add KERNEL_EXTRA_ARGS parameter so affected boards can add for example KERNEL_EXTRA_ARGS = "LOADADDR=0x80008000" to their configuration.

Previously the build path to STAGING_KERNEL_DIR was being embedded into the package post install scripts. We avoid this behavior by generating a special depmodwrapper script. This script contains that hard-coded path, ensuring that re-use of the sstate-cache (and/or packages) will always run through the wrapper generated by the current build with a checksum that includes STAGING_KERNEL_DIR.

2013-02-06package.bbclass: Add PACKAGESPLITFUNCS variableRichard Purdie
Prepending to populate_packages is rather ugly and means its hard to trace errors and also profiling informaiton is summed together in one function. This patch starts to split out the prepends to become separate functions to avoid these issues. This is generally a neater way to write functions than prepending to where there can sometimes be variable scope issues and we've been bitten by whitespace issues in the past.

2013-02-01kernel: avoid copying unnecessary files during do_installMark Asselstine
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.

2012-10-19kernel.bbclass: remove explicit version.h targetBruce Ashfield
The compilation routine for the kernel has an explicit call to build version.h, which works fine for most kernels, but the location of it has recently changes. commit d183e6f5 [UAPI: Move linux/version.h] commit 10b63956 [UAPI: Plumb the UAPI Kbuilds into the user header installation and checking] moves the file to include/generated/linux/version.h and then to include/generated/uapi/linux/version.h. As a result kernel builds of 3.7 or bisection builds of intermediate kernel commits will fail with: make[2]: *** No rule to make target `include/linux/version.h'. Stop. Making the explicit version.h build conditional on the version, or via a file test would fix the problem, but it introduces some complexity to the build. Even without an explicit call to build version.h, it is always produced by the kernel build, so it can simply be removed. This extra make line was originally so that the kernel version could be determined, so that then different instructions could be executed depending on whether it was a 2.4 or 2.6 kernel. Since we no longer support 2.4, this code is no longer needed.

[YOCTO #1614] Add the kernel headers to the kernel-dev package. This packages what was already built and kept in sysroots for building modules with bitbake. Making this available on the target requires removing some additional host binaries. Move the location to /usr/src/kernel Before use on the target, the user will need to: # cd /usr/src/kernel # make scripts This renders the kernel-misc recipe empty, so remove it. As we use /usr/src/kernel in several places (and I missed one in the previous version), add a KERNEL_SRC_DIR variable and use that throughout the class to avoid update errors in the future. Now that we package the kernel headers, drop the kernel_package_preprocess function which removed them from PKGD.

2012-06-21recipes-kernel: make perf a standalone packageLiang Li
perf has been coupled to the kernel packages via kernel.bbclass. While maintaining the build of perf out of the kernel source tree is desired the package coupling has proved to be awkward in several situations such as: - when a kernel recipe doesn't want to build/provide perf - when licensing of dependencies would prohibit perf and hence the kernel from being built. To solve some of these problems, this recipe is the extraction of the linux-tools.inc provided perf compilation into a standalone perf recipe that builds out of the kernel source, but is otherwise independent.

2012-06-21kernel: save $kerndir/tools and $kerndir/lib from pruningBruce Ashfield
The kernel source tree in the sysroot has all unecessary source code removed. The existing use case is to support module building out of the sysroot, but as more toolsa are moved into the kernel tree itself there are new use cases for the kernel sysroot source. To avoid putting dependencies on the kernel, and to be able to individually build and package these tools out of the source tree, we can save $kerndir/tools and $kernddir/lib from being removed. This enables tools like perf to be built our of the kernel source in the sysroot, without significantly increasing the amount of source in the sysroot.

2012-06-21kernel.bbclass: pass KERNEL_VERSION to depmod calls in postinstMartin Jansa
* without this, kernel upgrades where KERNEL_VERSION is changed e.g. 3.4.2 -> 3.4.3 generate .dep for running 3.4.2 and after reboot user ends up without any module loaded to make it worse after reboot nothing is upgraded to trigger another kernel(-module) postinst to generate .dep for now running 3.4.3 Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>
2012-05-30Revert "meta: replace os.popen with subprocess.Popen"Richard Purdie
This reverts commit e83d8e58a6b107eea87df0ec233a1bc932b2c6e as the conversion is not correct. Its replacing readlines() calls which generate an array with what are effectively strings. There are split("\n") calls missing in many cases so this needs to be reverted until it gets fixed.
2012-05-30meta: replace os.popen with subprocess.PopenRobert Yang
Replace os.popen with subprocess.Popen since the older function would fail (more or less) silently if the executed program cannot be found There are both bb.process.run() and bb.process.Popen() which wraps the subprocess module, use it for simplifying the code. Note: We don't need the "2>/dev/null" or "2>&1" since bb.process.run() can handle it, it will raise exception when error occurs, we should handle the exception ourselves if we want to ignore the error.
