      kernel.bbclass: add non-santized kernel provides · 3f45ebc8
      Bruce Ashfield authored 
      

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

 <build>

 % 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

      kernel: Add kernel headers to kernel-dev package · 8c724c4a
      Darren Hart authored 
      

[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 · 9ab875fb
      Liang Li authored 
      

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 · 72c4d30d
      Bruce Ashfield authored 
      

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.

      cpuburn-neon: fix packaging to use a date as version and valid sources · a17cda6e
      Otavio Salvador authored 
      

* The package were not versioning the sources as the files had no
   version on its name. We workaround it mangling the DL_DIR;

 * We now dynamically check if the machine has or not neon feature and
   set COMPATIBLE_MACHINE.
