Hi, I just checked the MAINTAINERS file in Linus tree and writing as a newbie in concerns of ARM architectures. So that's why I CCed people from whom I think I can get a helpful answer. Dunno how long my "lifetime-battery" will hold and it looks like such a cool Nexus-4 can make my life more happy. Getting older and wiser I want to use "stable" versions of whatever I use on any computer-systems, now. one of my next projects is to get a more modern Linux-kernel running on this beast. Linux v4.4.y LTS is currently my (stable) base on Ubuntu/precise AMD64. But I have no experiences with Linux on ARM. [ First steps ] First of all, I have updated my first smartphone a Google Nexus-4 (LG-E960 with 16Gbyte) with all available software-updates. AFAICS there is no more support than Android v5.1.1. Latest build is "lmy48t" and the codename "mako". [ Alternatives? ] Before flashing an alternative OS like CyanogenMod (CM) I wanted to get familiar with vanilla Android. [ A real alternative? ] I gasped at CM Git and there is a "cm-13.0" development branch for Android 6 "marshmallow" kernel. So there is a big pull-request where I looked into - it is still based on Linux v3.4. [ First questions ] Where moved "arch/arm/mach-msm" (don't see it in Linus Git)? Has Linux v4.4.y support for all the devices? Is it a solid base? Need a more modern Linux-version. ( I have not looked into the official tarballs from Google in [1] ). The CM-wiki says ARM-SoC is Qualcomm APQ8064 and GPU is Adreno 320. I guess I need a cross-toolchain for AMD64. As said I am new to all this. If you have any cool hints... Thanks in advance.
