One of the biggest changes made in Linux kernel 4.7 is the support for the newly announced Radeon 480 GPUs from AMD. As expected, this support has been embedded directly into the AMDGPU video driver.
Another big change comes to Linux kernel in the form of a new security module LoadPin. It makes sure that modules loaded by the Linux kernel originate from a single file system.
Interestingly, kernel 4.7 release introduces a new cpufreq governor named schedutil to help you change
your CPU’s operating frequency in a manner that would be more efficient than the existing solutions.
The other changes in Linux kernel 4.7 include the support for parallel directory lookups and firmware upgrade by following the EFI ‘Capsule’ mechanism.
