tree I want to use to build kernel: https://nv-tegra.nvidia.com/gitweb/?p=manifest/android/binary.git;a=tree;h=refs/heads/rel-32-shield-opensource;hb=refs/heads/rel-32-shield-opensource
there is even no build tools in updated tree...
I wanted to just do mp bootimage -j5 to build boot image but it's impossible.
Also I don't know how to build kernel outside AOSP tree.
Hint: somebody compiled kernel for Pie here but author is not answering question how to do this by ourself https://forum.xda-developers.com/t/kernel-rooted-pie-performance-enhanced-overclock-kernel.3943079/
Please point me a direction how can I build this kernel. I'd like to backport DVB support to it and aff some firmware blobs.
