On low performance SBCs it’s usually a good idea to turn off all debugging
inside the kernel.
Tz always good to gain some horsepower. That’s seen from a “user” perspective.
I did understand and do know that maintaining several kernels is helluva work. I wouldn’t expect a debugging-off kernel, being well aware that a designer usually appreciates debugging options turned on.
I do guess the only way around is to build a custom kernel. (Yes??)
If that is so. Is there a (reliable!) wiki/howto showing how to build a custom aarch64 ML kernel for a Manjaro PI installation?
