Hello!
This is a new version for the patch, against master branch:
http://lists.openembedded.org/pipermail/openembedded-core/2016-February/117603.html
@Martin, I pushed the results from testing with your script in a personal repo:
Tune results without the patch - clean open-embedded (master branch):
https://github.com/ddragomi/tune_test/tree/3f4054dd96e9d96c18e1eb9c5fef9f5ebc77f4a3/tune
Tune results with this patch:
https://github.com/ddragomi/tune_test/tree/ff9c904fa6fff38efdc72c604e6d5677b64f76a5/tune
And a diff between those here:
https://github.com/ddragomi/tune_test/commit/ff9c904fa6fff38efdc72c604e6d5677b64f76a5
NOTE: I also added a new fake-machine (axxiaarm) that require arch-arm8a.inc
to test/parse armv8a tunes:
DEFAULTTUNE ?= "armv8a-neon"
require conf/machine/include/arm/arch-armv8a.inc
Previous message:
Starting with linux-yocto-4.1, Intel provides kernel support for its
ARM v8 Axxia platforms, both on 32-bit and 64-bit.
Poky already contains arm 64-bit compiler tunings, so I added 32-bit
tunings based on those for armv7.
The patch that I send you is a draft. Please review it and if it's ok
I will return with thumb and big-endian tunings.

This patch adds tunes for 32-bit armv8 platforms. The user can select
the vector floating-point instruction set: vfpv4 or fp-armv8
and the thumb, neon, crc and crypto extensions.

First I would like to thank you for working on this. This is very
helpful and a good step in extending the ARMv8 platform support in
OE-Core.
I think you should also change the arch-arm64.inc file to use the
armv8a.inc file. So it is more consistent.

When I tried to use armv8at-crc-crypto-fp-armv8-neon as default tune,
it fails with:
Error, the PACKAGE_ARCHS variable does not contain TUNE_PKGARCH
(armv8a-crc-crypto-fp-armv8-vfp).

Thanks, Otavio!
I'll update also the arch-arm64.inc file to have 64bit support for armv8a
in a new version for the patch.

Did you used master or jethro?
Did you get this kind of error only for this tuneor there are also other
armv8a tunes that fails?
Thanks,
Daniel
