The latest Linux kernel has been released and there are many that we can offer to users and administrators alike. However, this particular release is especially pleasing to users who use Linux as a device that needs to be used by connecting to a file sharing server or NTFS partitioned drive. In addition to these heading changes, we see other new additions and improvements.

Let’s dive in and find out what they are.

NTFS is important

The most important feature introduced in the 5.15 kernel is a new NTFS filesystem driver named NTFS3. Prior to this release, anyone using the NTFS file system had to rely on the ntfs-3g userspace driver. It was buggy, slow, and lacked some important features. With NTFS3 (enhanced by Paragon Software’s code), users can:

  • Significantly improved read / write support
  • NTFS journal playback
  • Acl support
  • Usually compression and sparse file support
  • Support for NTFS file and folder creation dates from Windows drives.

Sure, most people are migrating beyond NTFS to exFAT, but that doesn’t mean they don’t need NTFS support. And given that Paragon Software has promised to keep this new kernel drive in the future, it’s clear that NTFS support will continue to play a role.

In-kernel SMB server

The latest Linux kernel also includes a new in-kernel SMB file service. The goal of ksmbd is not to replace Samba, but to provide a lightweight and fast kernel module compatible with userspace tools and libraries. This new in-kernel server can provide much faster SMB3 files and supports more features implemented directly in the kernel, such as SMB Direct’s RDMA support.

Hardware support

As expected, every time a new kernel is released, there is new hardware supported. The Linux kernel 5.15 is no exception. The following is a list of added or improved hardware support.

  • Temperature monitoring support has been added to AMD CPU and GPU improvements (AMD Zen 3 APU (Accelerated Processing Unit)).
  • Audio driver for Van Gough APU.
  • Support for more RDNA2 graphics cards (next generation AMD graphics cards should work right out of the box).
  • Added support for Intel Alder Lake (12th Generation Intel CPUs) (including the addition of the Time Coordinated Computing driver used to change the performance of Intel CPUs).
  • Initial support for Intel DG2 / Alchemist Discrete Graphics and XeHP (next generation Intel Xeon processor for HPC platforms).
  • Improved Apple M1 support (IOMMU driver integrated, USB and PCIe support added)
  • Added basic support for AMD Cyan Skillfish graphics
  • Optimization of C3 cache processing on AMD CPUs
  • The AMD PTDMA driver has been integrated to support high bandwidth memory-to-memory and I / O copy operations.
  • Realtek RTL8118 EU WiFi driver support
  • Support for Cirrus Logic Dolphin audio devices
  • Support for the NVIDIA Jetson TX2NX development kit.

Other additions

Other notable additions that come with the 5.15 kernel are Amazon’s DAMON (Data Access Monitor) support, support, XFS, EXT4, F2FS, and Btrfs filesystem optimizations that improve performance while reducing memory. Includes support for high resolution scrolling. Power profile support on specific Acer laptops using Apple Magic Mouse.

Do I need to install 5.15?

In a nutshell, no. The best bet is to wait for the kernel to be available through the Linux distribution of your choice. You can download and compile the latest kernel, but you cannot upgrade from your distribution’s package manager.

If you use a rolling release such as Arch or openSUSETumbleweed, you will receive the 5.15 kernel much faster than if the distribution you selected is a static release. Land for kernel 5.15 may be found on Ubuntu 22.04, which will be released in late April 2022. Therefore, unless these latest additions are absolutely urgent, it’s best to postpone until the distribution maintainer includes 5.15 in the official release. ..
