I think a big part of the reason is also the fact that several parts of the userland don’t compile for aarch64.
See e.g. https://github.com/raspberrypi/userland/issues/314
One of the first comments there also say about the RPi 3:
> The GPU is a 32 bit processor. I haven't checked, but I'm expecting that there's a heck of a lot more work to do to get Khronos or other multimedia extension stuff up and running against a 64bit kernel than just getting userland to build.
Don’t know if that’s the case for the RPi 4 as well.
And another comment too:
> I'm sure there are certain applications where having a 64-bit kernel (let alone userland) may be beneficial, but I suspect the hoped-for performance improvements didn't materialise, otherwise people would be waving benchmark results at us demanding an RPi-supported aarch64 kernel.
I’m missing this
Read the rest
too, and am planning on eventually doing some benchmarking of my own to see if there is any advantage of running the aarch64 kernel for my applications.
