I just took over my colleague work and I need to continue it.
Tunnings are new for meand I'm looking for a review about the actual
approach
from my colleague for adding ARMv8-a tunning for 32-bit.
No, I didn't ran such script.
Can you please tell me how to run it or at least where is this located.
It's scripts/tune/test.sh from
http://git.openembedded.org/openembedded-core-contrib/log/?h=jansa/tune2-test
?
It's there any Readme for it?
Thanks,
Daniel
