Linus Torvalds announced the release of the Linux kernel 4.18. The changes affect 13,067 files. Developers were able to make the kernel more compact by removing 677,480 and adding 578,788 code blocks.
It was a very calm week, and arguably I could just have released on schedule last week, but we did have some minor updates. Mostly networking, but some vfs race fixes (mentioned in the rc8 announcement as "pending") and a couple of driver fixes (scsi, networking, i2c). Some other minor random things (arm crypto fix, parisc memory ordering fix).
Two months passed since the announcement of the release candidate Linux 4.18-rc1, the developers conducted testing and eliminated kernel problems.
Most Important Changes
Changes affected the work with processors, file system and data storage, graphics processing. Some new features of Linux 4.18 should be highlighted:
- Basic support for Qualcomm Snapdragon 845 SoC.
- Support for Steam Controller from Valve.
- The core infrastructure is added to the kernel for BPFILTER, which processes the iptables API requests and passes them to BPF programs.
- DRM-driver AMDGPU now supports VegaM graphics processing on Intel Kabylake-G CPUs, as well as the forthcoming graphics card known as AMD Vega 20 GPU.
- Various AMDGPU power management enhancements, such as profiles for Vega.
- The AMDKFD kernel driver now supports GFX9 / Vega hardware.
- Intel finalized support for the micro-architecture of Ice Lake.
- Implemented by DM Writecache, which can be used to cache write operations of blocks on SSD-drives or in permanent memory.
- Improved support for USB 3.2 and USB Type-C.
- Already started work on a large update of Linux 4.19. It is assumed that this will be the latest version before 5.0.
Linux, open source OS, is developing rapidly. Only in 2018 came out the kernel versions 4.15, 4.16, 4.17, and now 4.18.
