[yocto] The kernel *.cfg system

[Koehler, Yannick (HP Networking)]

I am currently using Yocto Daisy (and daisy also for meta-fsl-ppc).

Note that I noticed in recent freescale meta layer they added code to inherit kernel and to handle partial cfg.  So I think the issue was with the linux-qorik-sdk package recipe and not yocto itself.  Since they have not based themselved on yocto-linux they do not offer fragment config support.

But in more recent of the linux-qorik I now see reference to partial cfg.

Hi Yannick,

I don't know if this could be related but was playing with kernel .cfg with meta-fsl and changing cfg didn't change I had to change the entire .config?


From:
https://lists.yoctoproject.org/pipermail/yocto/2015-February/023616.html

hmm I just notice that adding CONFIG_BT=m, when it was =y, in defconfig.cfg didn't change it even tried cleansstate. But it worked if I copy the original .config to my bbappend and change it inside...

I'm with yocto 1.7.1

NATIVELSBSTRING   = "Ubuntu-14.04"
TARGET_SYS        = "arm-poky-linux-gnueabi"
MACHINE           = "wandboard-quad"
DISTRO            = "poky"
DISTRO_VERSION    = "1.7.1"


Which version of yocto are you using by curiosity?

thx,

-KA

I attempted to alter the configuration file using a systemd.cfg for the pleasure, to my surprise, the .cfg didn't change anything at all.  Is FreeScale playing Yocto rules properly or is it me that missed something ?  I did the same as with linux-yocto:

I was wondering if it was because the Qoriq Kernel didn't include specific Yocto recipe instructions or class and it was something that I could easily add or if this needed to come from FreeScale itself, or if it was really just my setup having a problem.  Note that I did copy the systemd.cfg file at a proper location and bitbake did find it, even thought the final config under the /tmp/work/... didn't contain the changes.
