[Arm-dev] ?==?utf-8?q? supported 64bit hardware

[Jacco Ligthart]

Hi,

I previously build and packaged an aarch64 kernel for the C2 based on their kernel source on github. If there is interest in that, I could share that.

The building was a bit troublesome, as it did not work with the standard gcc in CentOS7. So I also rebuild a newer gcc from SCL.

I don’t know the advantages of a set of small, physically discrete, devices running a set of services, and I’d like to find out. I know they’d be a trainwreck for a customer-facing dynamically generated website. But what about NTP? True randomness maybe? How would they handle generating Kerberos tickets, or providing service discovery? Does XEN slow them down to a crawl? Can they generate synthetic load, and monitor the results? No idea.

So there’s no avoiding u-boot tinkering, /boot/ copying or kernel compiling when dealing with consumer boards like these. Does that sound right?
