The kernel is not compiled to have coresight enabled which would allow for very good program tracing with very little overhead.
Its basically these settings in the kernel .config:
Also the perf tool is in the Ubuntu repository, because of the custom kernel, perf does not have the necessary linux-tools-4.9.78-xxxx packages.
So could you please:
1. compile the kernel with coresight
2. make linux-tools-.... packages for that kernel available
3. make the hikey970 kernel available so I can make changes of my own and compile + install them. (e.g. via https://github.com/LeMaker ). As the kernel is GPL - dont you have to make the source available anyway?
EDIT: also supporting the "config" loadable module (or compiling it hard) would be nice!
