I saw there is a patch serial that try to add tuning for ARMv8 a year ago, but at that time, there is not much tune opinions, even the NEON FPU is not optional in all the cortex.
But when the A35 comes and gcc support more opinions on them, I think it is necessary to add support those thing in armv8. I have no idea how to support those big.little combo, there is too much pattern, I would like to only create tuning file for echo cortex IPs first. This patch is just sending for early check, whether it would be welcome. ayaka (3): [WIP]: arch-arm64.inc: allow soft fpu configure arch-armv8a.inc: add tune include for armv8 tune-cortexa17: add tunes for ARM Cortex-A35 meta/conf/machine/include/arm/arch-arm64.inc | 2 +- meta/conf/machine/include/arm/arch-armv8.inc | 1 - meta/conf/machine/include/arm/arch-armv8a.inc | 49 +++++++++++++++++++++++++++ meta/conf/machine/include/tune-cortexa35.inc | 24 +++++++++++++ 4 files changed, 74 insertions(+), 2 deletions(-) delete mode 100644 meta/conf/machine/include/arm/arch-armv8.inc create mode 100644 meta/conf/machine/include/arm/arch-armv8a.inc create mode 100644 meta/conf/machine/include/tune-cortexa35.inc -- 2.14.3 -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
