Richard/Saul,
Here is the re-work of the standalone perf build patch
series. We isolated the errors that Saul was seeing on the
autobuilder, and it stemmed from the misuse of the sources
symlink back into the working kernel directory. As Richard
pointed out, this would also break in a rm_work enabled
build.
I've also removed parts of the standalone recipe that were
inherited from its former life as a sub-part of the kernel
recipes (the non-standard depends usage, etc) as part of this
v2.
To build completely out of the sysroot patch 1/3 tells the
story. We just need to save $kerndir/tools and $kerndir/lib
from being removed during the pruning. As far as I'm concerned
this is small and reasonable, since there are a few tools in
the kernel source tree that are of interest and may want to
be built and packaged separately.
The find now has a couple more prunes in it, which of course
makes it a bit harder to read. If we really want, a new magic
variable could be created where recipes/kernel could specify
what should be saved in the sysroot .. but I didn't want to
go there yet.
I've built and runtime tested things here, and everything
looks sane.

We've wanted to do this for some time, and now have finally split
out perf from being a sub-part of the kernel packages into a
standalone package that is built out of the kernel sources.
I've built and tested this by adding task-core-tools-profile to
my IMAGE_INSTALL, and perf behaves just as it did before. I've
also tested this on my oe-core checkout/repo, and it works fine
there as well (but I'm using my easier to access contrib
branch for now).
There's additional work that can be done more easily once this
is split, so please consider this for inclusion, but I'd like
to keep this initial version as an exact functional match as
what was previously in place.
I've removed the old linux-tools.inc and updated any kernel
recipes that I know about that have references to it. If there
are other dependent recipes, they'll need to be updated.
From the patch itself:
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.
