Linux Kernel 4.5 officially arrives, has major improvements for AMD GPU drivers

The Linux Kernel 4.5 is now officially released and is up for download right now

Linux kernel 4.5 is officially here after being under development for over two months. Linux kernel 4.5 received a total of seven Release Candidate builds since January 25, 2016, with the last one having been officially announced by Linus Torvalds on March 6.

So what exactly is so promising about Linux Kernel 4.5? It includes the implementation of initial support for the AMD PowerPlay power management technology, and also brings in high performance to the AMD GPU open-source driver for Radeon GPUs. As a result, it will improve scalability in the free space handling of the Btrfs file system, and better epoll multithreaded scalability.

Furthermore, GCC, or GNU Compiler Collection’s UndefinedBehaviorSanitizer (UBSan) is now supported in Linux kernel 4.5 by using ‘-fsanitize=undefined,’ which is the memory controller now offers proper memory accounting of sockets.

Aside from that, madvise() has received support for the MADV_FREE flag. Linus Torvalds expresses his feelings over the release of the latest Kernel as he says the following:

“So this is later on a Sunday than my usual schedule, because I just couldn’t make up my mind whether I should do another rc8 or not, and kept just waffling about it. In the end, I obviously decided not to, but it could have gone either way. And on the whole, everything here is pretty small.”

Another key area in which Linux Kernel 4.5 brings an improvement is the addition of a copy_file_range system. This system implements support for copying files without the need to transfer any data through userspace and if you want a better term, it is called copy offloading.
