Linux kernel 4.18 was released two weeks ago, and it’s currently the most advanced Linux kernel series featuring mention Spectre V1 and V2 mitigations for 32-bit ARM architectures, Spectre V4 mitigations for ARM64 (AArch64) and ARMv8 architectures, as well as a just-in-time compiler for eBPF programs on 32-bit (x86) architectures. But that’s not all that is new in the Linux kernel 4.18, as Collabora’s devs did a great job to improve support for Chromebook devices by adding support for PWM-powered blacklight devices, a patchset containing various improvements, bug fixes, and cleanups for the Rockchip DRM driver and PSR support, as well as improvements to the defconfig for the Rockchip RK3399 platforms.
