Linux Kernel 6.0 official release

It seems that Linux Kernel 6.0 was officialy released a few days ago.
Here is the mail that Linus sent on 2 Oct.

Here are some key features:

Processors

AMD Zen systems gets a performance boost with updated NUMA balancing in the Kernel scheduler.

The Ratbleed speculative execution exploits fixing continues in this release affecting Intel 8th Gen+ and AMD Zen 1+ CPU family. Although the Ratbleed has not yet been found in the wild (only in Lab), the fix continues in this Kernel.

Lenovo and AMD bring the Automatic Mode Transition (AMT) support for Ryzen power ThinkPad laptops. This feature should give firmware-based power handling in those laptops with better efficiency.

New audio hardware support for AMD Ryzen 7000 desktop processors (Raphael) lands in this release with ACP 6.x support.

AMD is preparing for the release day with additional Instruction based sampling support for the Zen 4 series.

More CPU temperature monitoring code lands for AMD 17th and 19th family of models.

Initial work starts landing for Lenovo’s ARM Laptop X13 featuring Qualcomm Snapdragon 8cx Gen3 (SC8280XP) CPU.

Likewise, in all releases, a bunch of SOC chips get support in Linux Kernel 6. The most notable ones include NXP i.MX93 SoC (primarily used for smart devices in home solutions).

GPU

Work continues in this Kernel release for Intel DG2/Alchemist and AMD RDNA3 graphics cards; the support is entirely not there but is in progress for future versions.

A bunch of frame buffer device driver update (mostly fixes) arrives for Atari GPUs. Most noteworthy are the patchsets to fix VGA modes, colour handling and numerous code clean-ups.

Intel Meteor Lake GPU support is starting up in this release.
Storage and file systems

Like all releases, the famous and supported file systems are updated and improved.

Since the usage of SSDs is increasing, the flash-friendly file system (F2FS) enhances memory handling, garbage collection optimization and more.

One Microsoft employee provides a patch to improve locking performance & reliability for CIF/SMB3 protocol to improve multi-channel operation over the network.

Other assorted changes in Linux 6.0 include:

• Kernel support for NVMe in-band authentication
  

• Runtime verification subsystem
  

• Raspberry Pi 4 V3D kernel driver
  

• IO_uring user-space block driver 
  

• Buffered writes on XFS file systems
  

• Send Protocol V2 support for Btrfs
  

• H.265/HEVC API promoted to stable
  

In the following Linux Kernel 6.1 we will se implemented the Rust framework and many others.
