The Proposal
(Idea originally suggested by Mel Gorman)
Support for automatically building kernels with user-influenced configuration
an invention by vbabka
Sometimes a user might want to build her own kernel instead of using the provided binary, for various reasons. This means creating own .config and maintaining it through kernel version bumps, which often results in running "make oldconfig" and mostly holding down the enter button to accept upstream defaults. What I envision instead is a way to say where I want my own config to deviate from the distro default (as provided by e.g. kernel-stable on openSUSE), and only those options will override the distro default configuration. This distro default configuration is always updated for new upstream releases, so there should be no need to (manually or automatically) accept new upstream defaults, thus less risk of producing a broken kernel, as e.g. any new kernel options will be configured in the distro kernel so that they work with the distro itself (while upstream defaults might not be safe or desired).
Try to model check gfp_flags with cbmc
a project by vbabka
Paul McKenney's blog article inspired me to try apply his approach to kernel's memory allocation flags (gfp_flags) and how their combinations affect the decisions and actions taken during page allocation. Recent upstream development around these flags leads me to believe that the complexity is too high for me to reason about them and change the code without unintended changes in semantics. So it might be worth to let the computer do the hard work. If it works out, the approach should allow to verify that changing the code doesn't result in corner cases where some flag combinations don't work as intended. Then we can attempt to e.g. reduce the number of flags and perform other cleanups without fear of breaking everything.
Picopad development
