Will the Android kernel and underpinnings eventually go away? What are the plans for newer kernel releases?
We currently use an Android 3.1 kernel so we can interface with the binary drivers for the Tegra3 chipset that nVidia provides. We are currently working on merging this kernel with the official Ubuntu kernel.
This includes configuration and patches, assuming the patches can apply to a 3.1 kernel. If newer kernels are released for the Nexus7 by Google, then we will investigate the effort in migrating our changes to the new version and release one if feasible.
