[poky] Defconfig mods, Zynq-zx3 netmodule

[Michael Davis]

Hi David,

I am currently using the netmodule meta layer in yocto to build a kernel and ramdisk for my zynq zx3 on a starter board.  I need to enable kernel function tracing and a few other configurations in my build.  I need help on the correct way to enable kernel configurations (specifically I need CONFIG_FTRACE and CONFIG_PROFILING) using the meta layer.

 My attempts have been based on the KERNEL_DEFCONFIG_zynq_zx3_starter variable in recipes-kernel/linux/linux-zynq-git.bb.  I have tried specifying my own patch to create this file as well as pointing it to my own modified copy of the defconfig created by the patches in meta-netmodule.  After building, the modified defconfig file with the flags shows up in my work directory as .config but no changes ever appear in /proc/config.gz after booting my image.  I am able to verify that the 'make zynq_zx3_defconfig' step was run.  I wonder if the steps to do this are different here using the linux-zynq recipe as opposed to linux-yocto.  Any input on the correct way to do this would be greatly appreciated.

Thanks for the help in advance.

-Mike
