** Description changed: Impact: During the Bionic cycle, a decision was made to incorporate the linux-snapdragon kernel into the master branch, thus reducing the number of topic kernels and the stable maintenance burden. But as time passed and new patches were produced by Qualcomm, incorporating them into master while avoiding to destabilize generic became more and more problematic, down to the point where it was not a viable approach anymore. At that point, the decision was made to fork out linux-snapdragon into its own topic kernel (e.g. linux-raspi2), giving more room to incorporate new code coming from the Qualcomm tree and avoiding to destabilize any other target in generic. Fix: This is a three step process: 1) disable building linux-snapdragon from master by applying the attached patch to bionic/master - 2) create a new bionic/linux-snapdragon branch and reset hard to my + 2) create a new bionic/linux-snapdragon branch and reset hard to my lp:snapdragon-topic-kernel branch (see below) 3) update bionic-meta to point to the new bionic/linux-snapdragon kernel Regression potential From the point of view of bionic/master, this pull request doesn't introduce any substantial change, and in the future will let us purge generic from several external patches. - While from the point of view of linux-snapdragon, with ~900 code commits and ~8k + While from the point of view of linux-snapdragon, with ~600 code commits and ~4k config changes, this represent a brand new kernel and while great care was used while putting together this branch, there's clearly a regression potential here but we can't leave linux-snapdragon stagnate behind the curve, so the sooner we bite the bullet, the better we can the deal with the eventual fallout.
