An anonymous reader writes "With work done by ARM and Linaro, there is now a bootable image of Debian/Ubuntu that works for ARM64, the new 64-bit ARM architecture. There are still some caveats and work ahead, but Linux is once again the first platform that has software ready to run on a new architecture when released. This 64-bit ARM Linux support also includes the ability to run 32-bit ARM software side-by-side."
You can grab a bootable rootfs
, but there's no hardware to actually run it on now (the developers are using the free-as-in-beer simulator from ARM). Kernel support for the architecture
was released around a year ago; this is more a tale of getting from a bootable kernel to a bootable operating system.
