kernel.bbclass: add non-santized kernel provides

2012-07-09T15:59:00+00:00

If the kernel version string uses characters or symbols that need to be santized for the package name, we can end up with a mismatch between module requirements and what the kernel provides. The kernel version is pulled from utsrelease.h, which contains the exact string that was passed to the kernel build, not one that is santized, this can result in: echo "CONFIG_LOCALVERSION="\"MYVER+snapshot_standard\" >> ${B}/.config % rpm -qp kernel-module-uvesafb-3.4-r0.qemux86.rpm --requires update-modules kernel-3.4.3-MYVER+snapshot_standard % rpm -qp kernel-3.4.3-myver+snapshot-standard-3.4-r0.qemux86.rpm --provides kernel-3.4.3-myver+snapshot-standard = 3.4-r0 At rootfs assembly time, we'll have a dependency issue with the kernel providing the santizied string and the modules requiring the utsrelease.h string. To not break existing use cases, we can add a second provides to the kernel packaging with the unsantized version string, and allowing the kernel module packaging to be unchanged. RPROVIDES_kernel-base += "kernel-${KERNEL_VERSION}" % rpm -qp kernel-3.4.3-myver+snapshot-standard-3.4-r0.qemux86.rpm --provides kernel-3.4.3-MYVER+snapshot_standard kernel-3.4.3-myver+snapshot-standard = 3.4-r0 (From OE-Core rev: 7be043178f5b9d16d9a06696bc0b96689f202a8d) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

kernel: Add kernel headers to kernel-dev package

2012-07-04T16:40:33+00:00

[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. All *-sdk image recipes include dev-pkgs, so the kernel-dev package will be installed by default on all such images.

recipes-kernel: make perf a standalone package

2012-06-21T12:03:04+00:00

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. No new functionality is provided above what the linux-tools.inc variant provided, but the separate recipe provides baseline for adding new functionality.

kernel: save $kerndir/tools and $kerndir/lib from pruning

2012-06-21T12:03:03+00:00

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.

kernel.bbclass: pass KERNEL_VERSION to depmod calls in postinst

2012-06-21T12:03:02+00:00

* 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 (From OE-Core rev: 4bd5c17f55bc96ce6bbaccf6559aa4ea123ff4cb) Signed-off-by: Martin Jansa Signed-off-by: Richard Purdie

Revert "meta: replace os.popen with subprocess.Popen"

2012-05-30T13:21:29+00:00

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. Signed-off-by: Richard Purdie

meta: replace os.popen with subprocess.Popen

2012-05-30T11:04:45+00:00

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.
