kernel: Fix packaging issue

2012-09-28T15:53:13+00:00

Remove /etc since it is empty, when creating a machine that does not deliver any module config files, the /etc is empty and is then warned about not being shipped, so we remove it. This occurs in the routerstationpro with the following warning: WARNING: For recipe linux-yocto, the following files/directories were installed but not shipped in any package: WARNING: /etc (From OE-Core rev: 961498e3b4c4a93070bf278e67fc48c02333cd63) Signed-off-by: Saul Wold Signed-off-by: Richard Purdie

kernel.bbclass: add non-santized kernel provides

2012-09-28T15:53:09+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: 0af1d1412add1baf3f6c1a5cfb2e4f92fb6a85dc) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

kernel: Add kernel headers to kernel-dev package

2012-09-28T15:53:09+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.

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

2012-09-28T15:53:09+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

2012-09-28T15:53:08+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: 2a7cdf088e484bb123a72826a02c3169a418ed0a) Signed-off-by: Martin Jansa Signed-off-by: Richard Purdie

kernel.bbclass: Copy bounds.h only if it exists, needed for 2.6.x.

Linux 2.6.x kernels did not (all) have the bounds.h file, so copy only iff exists. (See OE-Core 02ac0d1b65389e1779d5f95047f761d7a82ef7a4) (From OE-Core rev: 6e9cfa4ba34d8899dfb271818ef30730de8353fa) Signed-off-by: Leon Woestenberg Signed-off-by: Scott Garman Signed-off-by: Richard Purdie

{kernel, module}.bbclass: don't run depmod for module packages during do_rootfs

2012-05-31T20:15:09+00:00

* depmod already gets executed by pkg_postinst_kernel-image. * If you build a module using module.bbclass, pkg_postinst returns 1 in do_rootfs, causing pkg_postinst to run again on first boot. To improve this situation, I copied pkg_postinst from kernel.bbclass to module.bbclass. This was rejected by Koen, because he doesn't like the code from kernel.bblcass, which uses ${STAGING_DIR_KERNEL}. Richard then suggested that calling depmod during do_rootfs wasn't necessary at all, because it already gets done by kernel-image.
