Linux 6.4 kernel released: initial support for Apple M2 chip

News on June 26th, the Linux 6.4 kernel has been officially released. This update brings many improvements, such as initial support for Apple M2 chips, improved storage performance, and sensor monitoring improvements, and more Rust code. While this isn't a major upgrade for the average user, it's a release worth keeping an eye on for those who want to take advantage of better hardware/software support.

It’s worth noting that this is a non-LTS release, so not everyone will need to upgrade to this release unless they encounter a specific issue that this kernel version solves.

This update has the following improvements:

• Initial support for Apple M2 chip
• Improvements in sensor monitoring
• AMD P-State guided autonomy Mode
• Storage performance improvement

Initial support for Apple's M2 chip

The Linux 6.4 kernel provides preliminary support for Apple's M2 system-on-chip (SoC) , and added device tree files for the current MacBook Air, Pro and Mac Mini systems. But there are still some problems, such as the inability of Apple M2 Mac Mini to display output and the inability to support new Apple laptop keyboards and touchpads. We can expect that these problems will be better solved when the Linux 6.5 kernel arrives.

Improvements in Sensor Monitoring

Similar to the previous kernel version, the Linux 6.4 kernel provides sensor monitoring capabilities for more than 100 ASUS motherboards, including both Intel and AMD platforms. PRIME, ROG, TUF, Pro, ProArt and other series are all supported.

AMD P-State Boot Autonomous Mode

After many efforts, AMD Boot Autonomous Mode has finally been integrated into the Linux kernel, which brings better performance to AMD EPYC and AMD Ryzen processors performance and power efficiency.

Improvement of storage performance

The Linux 6.4 kernel also brings many storage improvements, including:

• The EROFS file system has been optimized. Now Allows the use of subpage block support, which matches the AArch64 architecture.
• Various performance optimizations have been made to the EXT4 file system, as well as some minor tweaks to the NTFS file system, and the "No Access Rules" option is now removed.
• In addition, the Btrfs and F2FS file systems have also received some very nice enhancements, bringing performance improvements to different usage scenarios.

Other improvements and fixes

IT House noticed that in addition to the improvements mentioned above, there are some changes worth mentioning, such as:

• Support Intel linear address masking function.
• Stop supporting Intel Thunder Bay.
• Various optimizations have been made to LoongArch.
• Supports Intel Lunar Lake HD Audio.
• Improved the performance of VDUSE.
