I suspect we'll need an ubuntu specific fragment as well as all the

The Ubuntu packaging scripts check that various config options are set,
using these I have created an unbuntu.conf (attached) - I doubt this is

Very cool! Thanks so much for providing this! I'll add it to my tree.
The packaging scripts also have various checks for Linaro config options
which I believe are missing from linaro-base.conf, these are:
CONFIG_HW_PERF_EVENTS=y
CONFIG_ENABLE_DEFAULT_TRACERS=y || CONFIG_GENERIC_TRACER=y
I'll add these as well, thanks so much!
Finally, where can I find links to any docs on config fragments? I
started trying to create a fragment for vexpress which just contained:
CONFIG_ARCH_VEXPRESS=y
CONFIG_ARCH_VEXPRESS_CA9X4=y
but merge_config.sh said "Value requested for CONFIG_ARCH_VEXPRESS not
in final .config".
So this is likely due to the ARCH_VEXPRESS option having dependencies
that aren't met.
They way I usually sort this out is, after building the config. I call
make menuconfig and hit "/ARCH_VEXPRESS" and it will show the current
state of the dependencies for that option. The ones that aren't set, I
then add to the config fragment.
But as the larger point about documentation, its severely lacking right
now. My apologies for that. I'll see if I can find some time in the
near future to improve this. If you have any specific documentation
suggestions, I'd be happy to incorporate them .
thanks
