Linux Kernel 5.3 – the most important changes
Support for AMD Navi cards and Zhaoxin processors
Along with the debut of Linux Kernel 5.3, support for AMDGPU drivers and AMD Navi graphics cards is coming – we are talking about the Radeon RX 5700 series. Additionally, x86 Zhaoxin processors are now supported, which will be of marginal importance for Poles.
Support for Intel Speed Select
Intel Speed Select (Intel SST) technology introduced at the launch of Intel Cascade Lake is now supported. It allows the user to configure a single server according to its workload. Intel SST offers an interface that allows you to control and set the core frequency of cores.
New pidfd_open (2) system call and other improvements
The pidfd_open (2) system call is intended to help solve problems when reusing the PID controller, adds support for umwait x86 instructions to increase user space energy efficiency, and support for a light and flexible built-in ACRN hypervisor. Don't forget to support 16 million new IPv4 addresses in the 0.0.0.0/8 range.
The use of Linux Kernel 5.3 is not yet recommended for production environments. The release will be marked as stable only after the release of the first minor update for this version.
