Two months in the works and eight RC (Release Candidate) builds later, the final Linux 5.3 kernel is now available, bringing quite some interesting additions to improve hardware support, but also the overall performance. Linux kernel 5.3 had an extra Release Candidate because of Linus Torvalds’ travel schedule, but it also brought in a few needed fixes. Highlights of the Linux 5.3 kernel series include support for Intel Speed Select to make power tuning much easier on certain Xeon servers, support for AMD Radeon Navi graphics cards, such as the AMD Radeon RX5700, in the AMDGPU driver, support for Zhaoxin x86 processors, as well as support for the utilization clamping mechanism in power-asymmetric CPUs.
