Hi! I was wondering how to apply some extra kernel configuration from a custom layer via a bbappend. I know that with meta-raspberrypi there exist some variables you can define in local.conf that will drive how the kernel is configured: but what about some very specific device driver nobody than me is interest in? To me it seems it doesn't deserve a dedicated global oe variable.
Some investigation showed this topic already came up on the list from time to time in the past (most recently in [1]). To me it looks like there is some common desire to get rid of the current "magic" carried out by linux-rpi.inc by moving the linux-raspberrypi recipes into the configuration fragments style. In the short term, my question are: how do you guys manage to add your custom kernel configurations? Do you rely on full blown static defconfigs? Have you found any reliable way to do "differential" configurations with the current state of metadata? In a longer term, I'd really like to help moving towards supporting configuration fragments for linux-raspberrypi, but I suspect it'd be a too much hard task for my current understanding of the whole kernel configuration workflow. Do you know of anyone already working on this or does anyone have a clear idea of what is needed to get the work done? Some times ago I tried to resurrect [2], but with no luck, probably due to some changes that happened in the linux-yocto files in the meanwhile. Comments from gurus are welcome! ;-) [1] https://lists.yoctoproject.org/pipermail/yocto/2016-December/033559.html [2] https://lists.yoctoproject.org/pipermail/yocto/2015-October/027034.html
