As ARM CPUs are showing their competence as a replacement for x86 based CPUs more and more Linux distributions are trying to support ARM. We need to remind you that, Linux distros were supporting ARM for a long time. The first distribution to support ARM architecture was Debian back in the year 2000. Currently, many distros are supporting 64-bit ARM including Arch Linux, Ubuntu, Gentoo, Slackware, Manjaro, etc.
