Linux on ARMLinux 4.7 introduced support for AMD Radeon RX480 GPUs, parallel directory lookups, the new “schedutil” frequency governor with lower latency, EFI ‘Capsule’ firmware updates, and much more.

Some notable Linux 4.8 changes include:

  • HDMI-CEC framework
  • Kernel documentation system is now based on Sphinx
  • GPIO subsystem has a new user-space ABI for the management of general-purpose I/O lines; it is based on char devices and replaces the long-deprecated sysfs interface. You can check out tools/gpio/ directory with lsgpio, gpio-hammer, and gpio-event-mon for examples
  • Various file systems improvements for Btrfs, EXT-4 (unified encryption), OrangeFS (better in-kernel caching), Ceph (RADOS namespace support), XFS (Reverse-mapping support), etc…
