So after talking about it at the last Linaro Connect, I've finally gotten around to making a first pass at providing config fragments for the linaro kernel. I'd like to propose merging this for 12.04, and doing so early so we can make sure that all the desired config options are present in the fragments and to allow the vairous linaro build systems to begin migrating their config generation over.
The current tree is here:
http://git.linaro.org/gitweb?p=people/jstultz/android.git;a=shortlog;h=refs/heads/linaro-configs-3.3[...]
I'd ask Landing teams to take a look at this, and report any missing config options or fragment chunks they'd like to see.
John, I've attached a config fragment for Versatile Express.
Great! I've merged that in! There's a few warnings though:
Value requested for CONFIG_ARCH_VEXPRESS_DT not in final .config Requested value: CONFIG_ARCH_VEXPRESS_DT=y Actual value:
Value requested for CONFIG_FB_ARMHDLCD not in final .config Requested value: CONFIG_FB_ARMHDLCD=y Actual value:
I'm guessing these are features not in the base 3.3 tree? If so you might want to break those out and re-add them with those patches.
This includes loadable module support because one of our topic branches adds the gator module with a default config of 'm'. I did this because Linaro kernels are expected to have this module available but I didn't see any reason for it to be built-in, and as there may be versioning issues between it and the separate user side daemon, I thought it wise to keep the door open for loading an alternate module obtained from elsewhere. That decision does mean that all Linaro kernels would need loadable module support built in, but I don't think that is a bad idea.
Tushar had similar request, but I don't think the android configs (at least the ones I've managed) use modules, so I've added the MODULES=y to the common ubuntu.conf file.
If this is still objectionable, it can be changed and we can push it down to the linaro-base.conf, but I want to make sure the Android tree doesn't run into trouble.
