[PATCH] kernel.bbclass: Allow INITRAMFS_TASK to trigger copy initramfs code

[PATCH] kernel.bbclass: Allow INITRAMFS_TASK to trigger copy initramfs code

[Jason Wessel]

Activating the INITRAMFS_TASK can cause circular dependencies, but
that is up to the end user to resolve in recipes.  The INITRAMFS_TASK
should also trigger immediate linking of the cpio task in the first
compile pass.  This was a subtle regression introduced by: 609d5a9ab
(kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency
and bundling).

This patch restores the previous behavior and only affects the
INITRAMFS_TASK which is not set by any of the default build profiles
in oe-core.

Re: [PATCH] kernel.bbclass: Allow INITRAMFS_TASK to trigger copy initramfs code

[Andrea Adami]

Jason,

there is one more problem here:

| DEBUG: Executing shell function do_compile
| Copying initramfs into ./usr ...
| cp: cannot create regular file
'/oe/oe-core/build/tmp-eglibc/work/poodle-oe-linux-gnueabi/linux-yocto-tiny-kexecboot/3.10.11+gitAUTOINC+dad2b7e1ce_e1aa804148-r0/linux-poodle-tiny-build/usr/.':
No such file or directory

I'm solving it this way:

copy_initramfs() {
        echo "Covpying initramfs into ./usr ..."
+        mkdir -p ${B}/usr
        # Find and use the first initramfs image archive type we find


Please take care of this.
Thanks

Andrea

I suppose that one makes sense given that the compile directory might not exist.  My testing did not show this problem because my working env was "dirty".

Thanks for the report, your fix is perfectly fine.  I'll send a v2.

Jason.
