The biggest new features of Linux kernel 4.7 are support for the recently announced Radeon RX 480 GPUs (Graphic Processing Units) from AMD, which, of course, has been implemented directly into the AMDGPU video driver, a brand-new security module, called LoadPin, that makes sure the modules loaded by the kernel all originate from the same file system, and support for generating virtual USB Device Controllers in USB/IP.
Furthermore, Linux kernel 4.7 is the first one to ensure the production-ready status of the sync_file fencing mechanism used in the Android mobile operating system, allow Berkeley Packet Filter (BPF) programs to attach to tracepoints, as well as to introduce the long-anticipated “schedutil” frequency governor to the cpufreq dynamic frequency scaling subsystem, which promises to be faster and more accurate than existing ones.
