Linus Torvalds today announced the official version of the Linux Kernel 5.4 kernel. As an important version update, 5.4 not only updates drivers to provide better hardware support, enhances security, but also introduces many new features. The Linux Kernel 5.4 branch went into development in October with eight candidate version updates. Of the many new features introduced this time, the most interesting is the initial support for the Microsoft exFAT file system so that users can get the out-of-the-box experience when connecting to exFAT-format disks.
Another major improvement in Linux Kernel 5.4 is the Kernel Lock down feature, which restricts access to the kernel for certain applications by deploying in the Linux Security Module module. 5.4 A new layer of protection has been added to enable it to run the software as intended by its creator, thereby preventing malicious actors.
In addition, Linux 5.4 adds support for AMD Radeon Navi 12/14 GPU, AMD Radeon Arcturus GPU, and AMD Dali APU. In addition, the AMD Ryzen 3000 Series CPUs are supported by temperature reporting, and the AMD EPYC microprocessor now improves load balancing.
Other notable features include support for the Intel Tiger Lake CPU, support for Qualcomm Snapdragon 855 SoC, and support for Intel Lightning Mountain SoC. In addition, an application memory management mechanism called virtio-fs was introduced on Android, which is a high-performance virtio driver that shares files between hosts and guests There are also fs-verity for detecting whether a file has been tampered with and dm-clone for Live clone block devices.
Linus Torvalds, chief executive, said: “The merge window for Linux Kernel 5.5 is clearly open. While the upcoming Thanksgiving holiday isn’t an ideal development cycle, I hope it won’t be too much of a problem. If I’m behind (not because I’m lazy), the main reason is that I’m spending the holidays with my three kids, and I might merge some of the content into the second week. It depends on the situation. “
