Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizens Wu Yanzu in South China for the delivery of clues! CTOnews.com June 26, the Linux 6.4 kernel has been officially released, and this update has brought a number of improvements, such as initial support for Apple's M2 chip, improved storage performance, improved sensor monitoring, and more Rust code. While this is not a major upgrade for the average user, it is a noteworthy version for those who want to take advantage of better hardware / software support.

It is worth noting that this is a non-long-term supported (non-LTS) version, so not everyone needs to upgrade to this version unless they encounter specific problems that this kernel version can solve.

This update is improved as follows:

Initial support for Apple M2 chip

Improvement of sensor monitoring

AMD P-State Boot Autonomous Mode

Improvement in storage performance

Preliminary support for Apple M2 Core Linux 6.4 kernel provides preliminary support for Apple's M2 system-on-chip (SoC), and adds device tree files for current MacBook Air, Pro and Mac Mini systems. But there are still some problems, such as the inability of the Apple M2 Mac Mini to display output and the lack of support for the new Apple laptop keyboard and touchpad, which can be expected to be better resolved with the arrival of the Linux 6.5 kernel.

The sensor monitoring improvements are similar to the previous kernel version, which provides sensor monitoring capabilities for more than 100 Asustek motherboards, including Intel and AMD platforms. PRIME, ROG, TUF, Pro, ProArt and other series are within the scope of support.

After many efforts, AMD P-State boot autonomous mode has finally been integrated into the Linux kernel, which brings better performance and power efficiency for AMD EPYC and AMD Ryzen processors.

Improvement in storage performance Linux 6.4 kernel also brings a number of storage improvements, including:

-the EROFS file system has been optimized to allow sub-page block support, which matches the AArch64 architecture.

-with various performance optimizations for the EXT4 file system and some minor adjustments to the NTFS file system, the option of "no access rule" is now removed.

-in addition, the Btrfs and F2FS file systems have also received some very good enhancements, resulting in performance improvements for different usage scenarios.

Other improvements and fixes CTOnews.com noted that in addition to the improvements mentioned above, there are some changes worth mentioning, such as:

-supports Intel linear address masking.

-stop supporting Intel Thunder Bay.

-various optimizations have been made to LoongArch.

-support Intel Lunar Lake HD audio.

-improves the performance of VDUSE.
