[meta-freescale] Tuning for e600 target?

[zhenhua.luo at freescale.com]

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,

Subject: [meta-freescale] Tuning for e600 target?

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
