Collabora developers working on the Linux kernel are reporting on the commits they made during the development cycle of the Linux 5.4 kernel series.

Released last month on November 24th, the Linux 5.4 kernel series brings exciting new features for Linux users everywhere, including the long-anticipated support for Microsoft's proprietary exFAT file system, as well as a new kernel lockdown feature for extra security, and a bunch of improvements for AMD gamers.

Linux Kernel 5.4 also adds a new security feature for detecting file tampering called fs-verity, a new dm-clone tool for live cloning of block devices, a new high-performance virtio driver for sharing files between hosts and guests called virtio-fs, improved app memory management on Android devices, and support for Intel Tiger Lake CPUs.

Collabora's contributions to Linux Kernel 5.4

Collabora's kernel developers have contributed a total of 95 commits to the Linux 5.4 kernel series, adding H.264 and VP8 video decoding on several Chromebooks using the Rockchip RK3288 and RK3399 chips, which are being used in ASUS Chromebook Flip and ASUS C201 Chromebook. This change along brings Chromebooks one step closer to running upstream, said Collabora.

"Continuing with our work on Chromebooks, Chrome OS Embedded Controller platform drivers were restructured, from an architecture point-of-view," reports Enric Balletbò i Serra, which managed to cleane up an old issue causing crossed references between the MFD (Multi-Function Devices) subsytem and the Chrome Platform subsystem, which paves the way for an easier and cleaner workflow for developers.

Collabora devs also contributed on improving upstream kernel quality, added support of the NOA1305 ambient light sensor, added new properties to the Chrome OS EC sensors core, and helped the Linux kernel maintainers by contributing 124 Reviewed-by tags.
