[PATCH 1/3] base.bbclass: Avoid explicit ${MAKE} in do_configure

[Otavio Salvador]

The do_configure may eventually call 'make clean' when the sstate
signature does not match. We should respect EXTRA_OEMAKE when doing
so, so use 'oe_runmake' for it.

[PATCH 2/3] module.bbclass: Add KERNEL_SRC in EXTRA_OEMAKE

[Otavio Salvador]

When the sstate hash changes for do_configure task, the do_configure
default implementation triggers the 'clean' to be run. For it to
succeed we need to have KERNEL_SRC defined in EXTRA_OEMAKE. Fixes
following error:

,----
| DEBUG: Executing shell function do_configure
| NOTE: make -e MAKEFLAGS= clean
| make -C  M=.../tmp/work/... clean

| Makefile:20: recipe for target 'clean' failed

[PATCH 3/3] kernel.bbclass: When linux/version.h exists, copy it

[Otavio Salvador]

Old Linux kernel versions rely on linux/version.h for modules; this
needs to be published for external modules to use. Copy it when
available.

Re: [PATCH 3/3] kernel.bbclass: When linux/version.h exists, copy it

[Bruce Ashfield]

Unless anyone needs these really fast, I'll queue the two kernel
patches and take them
for a spin today.

I have a variant of the version.h here (and when the directories
shuffle again, we can drop
explicit copies all together), but will make the switch for this in
the short term.

We have failures due this in meta-fsl-arm; it is for master only so we
can live with failures for some days.

I am happy you have something in same line.

I wanted to reproduce this locally, since I've never seen the problem
myself.

What's the best way to trigger the sstate hash change ?

I also have a question below ...

I'm not seeing very well at the moment and my ability to browse the code
is restricted, so bear with a potentially stupid question.

It's clear from the error message above why this is needed, but I'm not
seeing the code that is respecting/using KERNEL_SRC to trigger the
clean in the right directory. Where exactly is this being used (I know your
related base.bbclass change will pull in the extra make args, but I'm just
not seeing the Makefile that respects it).

Basically, I'm trying to decide if it would be better to handle this all in
the module class, and add a do_configure to the do_compile and
do_install we already have.

Since I'm not seeing it, others might not as well .. and we can enhance the
comments to make it clear.

This was triggered when I did a change in the kernel-module-mcc; so
when I changed the recipe it triggered the configure.

No worries.

It was triggered from the module Makefile. So it basically runned:

make clean

and it tried to load it from kernel source, which obviously failed.
