Hello!

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.

Thank you,
Cristian Bercaru (1):
  add tunings for 32-bit ARMv8-a

This patch adds tunes for 32-bit armv8 platforms. The used can select
the vector floating-point instruction set: vfpv3, vfpv4 or fp-armv8
and the Neon, crc and crypto extensions.

So, what do you guys think about my patch? Is the armv8a support a 
valuable addition to poky?

Wrong ML, it belongs to oe-core ML.

Please check this patchset:
http://git.openembedded.org/openembedded-core-contrib/log/?h=jansa/tune3
and test script provided in:
http://git.openembedded.org/openembedded-core-contrib/log/?h=jansa/tune2-test

It was sent couple months ago, you can find the discussion in various
threads, e.g.:
http://lists.openembedded.org/pipermail/openembedded-core/2015-October/111318.html
http://lists.openembedded.org/pipermail/openembedded-core/2015-November/112907.html

It fixes some of these issues and simplifies implementing the rest.

feature-arm-vfp.inc is included in armv5.inc, so it makes a lot of these
features added to TUNEVALID actually invalid for armv[56] MACHINEs.

* [PATCH] ARMv8 32-bit compiler tunings
@ 2016-02-16 14:28 Daniel Dragomir

Hello!

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.

Thank you,
Cristian Bercaru (1):
  add tunings for 32-bit ARMv8-a
