The Colorado developer team reports on the many contributions made to the Linux 5.4 kernel

In the latest submission of Commit, the Collabora developer team reports on the efforts made during the development of the Linux 5.4 kernel branch. Launched on November 24th, the Linux Kernel 5.4 Stable Edition bringsĀ  exciting features to Linux users around the world, including the much-anticipated exFAT file system support, the ability to enable new kernel locking features for security, and a range of improvements for AMD gamers.

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.

The Colorado developer team submitted 95 Commits to the Linux 5.4 kernel, adding H.264 and VP8 video decoding to multiple Chromebooks using rockchip RK3288 and RK3399 chips, which have been used in ASUS Used in Chromebook Flip and ASUS C201 Chromebook. The change brings Chromebooks one step closer to upstream products, says Collabora.

“From an architectural point of view, we continued to do a lot of work on chromebooks and reorganised the Chrome OS embedded controller platform drivers,” enricballetb?i Serra reports. “The file managed to address a subsystem that led to the MFD (Multi-Functional Device) subsystem and the Chrome Platform subsystem, paving the way for developers to simplify and clean their workflows.

The Colorado developers also contributed to improving upstream kernel quality by adding support for the NOA1305 ambient light sensor, adding new properties to the Chrome OS EC sensor kernel, and contributing 124 “reviewer” tags to help Linux kernel maintainers.
