fsl-dynamic-packagearch: on thumb builds, add MACHINE_SOCARCH arm feed

This ensures that all MACHINE_SOCARCH feeds are part of PACKAGE_EXTRA_ARCHS.

oe-core now puts packages into an arm feed dir when a recipe forces the ARM instruction set on a build configured to default to thumb.
http://cgit.openembedded.org/openembedded-core/commit/?id=3e760031f91fb87c3e2f62b77a117eb41164f259

This is true also for packages in MACHINE_SOCARCH, i.e. we get in deploy/ipk for an angstrom based build:
armv7ahf-vfp-neon-mx6qdl armv7at2hf-vfp-neon-mx6qdl
so we must put both into PACKAGE_EXTRA_ARCHS.

In theorie, but less likely, the opposite is also true. If a recipe explicitely sets thumb in a build configured for arm the resulting packages end up in a thumb feed.

---
v2:
- moved the functionality from imx-base.inc to fsl-dynamic-packagearch.bbclass
- implements the'vice versa' recipe with thumb on default arm configuration
- reads the datastore to construct the feed name rather than relying on "t2"

v3:
- removed PACKAGE_EXTRA_ARCHS from mxs-base.inc also.

Minimal Use Case to reproduce the issue:

- fsl-community-bsp setup, master
- default to thumb instruction set and add a SOCARCH package which forces arm:
local.conf:
ARM_INSTRUCTION_SET ?= "thumb"
DEFAULTTUNE_mx6 = "cortexa9thf-neon"
CORE_IMAGE_EXTRA_INSTALL += "libasound"

- build core-image-minimal

1.8.4.5

Hello Max,

(I have added some more people to the Cc list as I think this is a generic problem)

For reference of the source changes, the patch is online[1].

1. http://patchwork.openembedded.org/patch/90989/

I think when thumb is used, the normal ARM should be added but the inverse shouldn't be truth as I might want to not use thumb at all.

In any case, I think this should be handled in the generic code which adds the PACKAGE_EXTRA_ARCHES and not in our class.

Please people, I need your view on this...

Hi

2015-03-27 23:33 GMT+01:00 Otavio Salvador <[email protected]>:

Note that this use case is more academic. I have not found a single recipe which forces thumb mode in the layers I have on disk. Plus I did not test if and how a build would fail when adding such a recipe to an image.

Regards
Max
