Kernel 4.14 Released – Install Linux Kernel 4.14 On Ubuntu

Linux Kernel 4.14 Released. Update and install Linux Kernel 4.14 on Ubuntu Systems. Linux Kernel 4.14 LTS “Fearless Coyote” brings many new drivers and improvements.

Linux Kernel 4.14 brings support for bigger memory limits in x86 hardware (128PiB of virtual address space, 4PiB of physical address space); support for AMD Secure Memory Encryption; a new unwinder that provides better kernel traces and a smaller kernel size; support for the zstd compression algorithm has been added to Btrfs and Squashfs; support for zero-copy of data from user memory to sockets; support for Heterogeneous Memory Management that will be needed in future GPUs; better cpufreq behaviour in some corner cases; Longer-lived TLB entries by using the PCID CPU feature; asynchronous non-blocking buffered reads; and many new drivers and other improvements.

Announcing the release, Linus Torvalds wrote:

The biggest thing that stands out in the diffstat is the “leaking_addresses” perl script, which is actually under active development, but I put the first version in for 4.14 just so that people could see that initial state and start looking at the end result and perhaps ask themselves “should my code make these kernel addresses visible to user space”. The most noticeable last-minute change is probably that we had to revert the code that showed a good MHz value in /proc/cpuinfo even for the modern “CPU picks frequency dynamically” case. It worked fine, but it was much too expensive on machines with tens or hundreds of CPU cores. There’s a cunning plan, but it didn’t make 4.14, so we’ll get it working and then back-port.

Anyway, go out and test the new 4.14 release, that is slated to be the next LTS kernel – and start sending me pull request for the 4.15 merge window.
