Many 64-bit ARM Changes Coming To Linux 4.4 Kernel

Written by Michael Larabel in Arm on 4 November 2015 at 05:14 PM EST. Add A Comment

Many 64-bit ARM (ARM64) changes are inbound for the Linux 4.4 kernel.

First up with the Xen feature pull there is support for 64 KiB guest pages on 64-bit ARM along with CPU hot-plug support on ARM.

Also sent in today was the heavy ARM64 updates. Work there includes KAddressSanitizer (KASan) support, a rework of CPU feature detection for ARM64 CPU cores exposing different levels of fuunctionality, support for 16KB pages, native atomics, and a variety of other changes.

Of course, more changes are still pending with the ARM platform updates and more that have yet to be sent out with just being a few days into the Linux 4.4 merge window.

It's great to see the ARM 64-bit support maturing upstream with many -- exciting -- 64-bit ARM boards still working their way out there.
