Hello
i'm building a yocto image for MPC641D (e600) PowerPC processor.
The problem is that i don't know which tuning parameters to choose for this
target.
Openembedded seems to have a tuning configuration in tune-ppce600.inc.
Unfortunately this information doesn't exist in yocto project.
Can you tell me how to get a valid tuning config for ppce600 ?
Kind regards,
chris

Hello Chris,
I don't know whether existent tune file can be used for this platform, following is my suggestion.
Find out the cpu type(-mcpu=<cpu-type>, -with-cpu=<cpu-type>) of the machine, and then search if there is match tune file. If there is no match one, you can create a new tune for ppce600.
Below is the available ppc tune file in poky.
· ./meta/conf/machine/include/tune-ppce300c2.inc
· ./meta/conf/machine/include/tune-ppce500v2.inc
· ./meta/conf/machine/include/tune-ppc476.inc
· ./meta/conf/machine/include/tune-ppce6500.inc
· ./meta/conf/machine/include/tune-ppce5500.inc
· ./meta/conf/machine/include/tune-ppc7400.inc
· ./meta/conf/machine/include/tune-ppce500.inc
· ./meta/conf/machine/include/tune-ppc603e.inc
· ./meta/conf/machine/include/tune-ppce500mc.inc
· ./meta/conf/machine/include/tune-ppce300c3.inc
Best Regards,
Zhenhua
