Question on the state of aarch64 support for Raspberry Pi 3

Post by espressobeanies » 2018/10/18 17:04:30

This might be a bit off-topic for this kind of forum, but I popped a question on the 'arm-dev' mailing list for CentOS 7 about asking if CentOS 7 'aarch64' would include RPi3's and I haven't heard anything back. To be honest, the entire mailing list seems dead. I know it would require a lot of work to achieve, but wanted to see if anyone was looking at doing it or whether something is already in the pipeline. Thanks!

According to the search option people had already installed CentOS7 on raspberry.

Yes, but the current CentOS distro available is only 32bits and the RPi3 CPU operates at 64.

Hardware support for ARMv8 can be found on the following page. The Raspberry Pi hardware is not on the list of those.

https://wiki.centos.org/SpecialInterest ... ch/AArch64

I’ve got a Raspberry Pi 3B+ and for the 32-bit builds only the RPi image works, the generic one fails to boot (AFAICT).

The question is whether or not 64-bit is worth it. There’s only 1GB of RAM, so there goes the use case of addressing more than 4GB of RAM. And pointers and some data sizes can double, taking up more memory than their 32-bit counterparts. I don’t know anyone looking to do 64-bit integer/floating calculations on a Pi, but to each theo own ;)

I’d rather see a patched kernel that correctly identifies the Pi’s hardware.

Cheers,
Mike
