Public bug reported: In order to resolve some bugs, to workaround some hardware quirk, or to help developers test some bug-fixing patch it would be able to:
- Get the sources of the *current* (non mainline) ubuntu kernel - Apply some patch - Rebuild the kernel in a PPA (so that it can be made available to multiple people for testing). Unfortunately, there is no documentation on how to do this. In fact, to the best of my understanding there is no documentation on how to build patched kernels in PPAs at all. This seems to be both possible and involving some special recipes, because in some occasions I've been pointed by ubuntu developers to try some specially patched version of the current kernel made available via a PPA. Specifically, at the present time, I would like to try and help trying the patch in git://github.com/vsyrjala/linux.git plane_assert_v4.13 which is not yet available in mainline. In other occasions I had similar situations with other patches. Please let me remark again that I am not looking for ways of building patched versions of the mainline kernel in a PPA (for this I have found some informal instructions in https://askubuntu.com/questions/784796 /ppa-upload-of-custom-kernel-package/841981#841981 (incidentally, this too should in my opinion be officially documented). I am looking for ways to build a patched current kernel, so that: - systems needing proprietary drivers can be supported - patches can be tested with the current ubuntu kernel - as new versions of the ubuntu kernel for some distro come out, it is easy to bring forward the patch if needed. Thanks!
