Linux 5.12 – Main Changes, Arm, MIPS and RISC-V Architectures

Linux 5.12

Linux 5.12 release was expected last Sunday, but Linus Torvalds decided to release one more release candidate, namely Linux 5.12-RC8, to “make sure things are all settled down“, so the latest Linux kernel is now expected this weekend.  Tihs should not yield any significant changes, so we can check what’s new in Linux 5.12, notably with regards to Arm, MIPS, and RISC-V architectures often used in SoC’s found in embedded systems. Around two months ago, the release of Linux 5.11 added support for Intel’s software guard extensions (SGX) and Platform Monitoring Technology (PMT), AMD “Van Gogh” and “Dimgrey cavefish” graphics processors, MIPI I3C host controller interfaces, and much more. Some interesting changes in Linux 5.12 include: Added support for ACRN hypervisor designed for IoT & embedded devices Added support for Playstation DualSense & Nintendo 64 game controllers, as well as Nintendo 64 data cartridges Dynamic thermal power management via a subsystem that allows the power usage of groups of devices […]

RK3566 & RK3568 processors to get Linux mainline support soon

Rockchip RK3566 RK3568 mainline Linux

Rockchip RK3566 & RK3568 processors were just officially announced at the end of the year, and soon followed with announcements of related such as Core-3568J AI Core system-on-module, some Android 11 TV boxes, Station P2 mini PC, and RK3566/RK3568 development boards. But it did not take long, as RK3566/RK3568 are about the get support for mainline Linux, with engineers from Collabora and Rockchip having recently committed preliminary support for RK356x platforms, notably using Pine64 Quartz64 SBC for testing. The most recent commits target power management, networking, and the PCI host controller. It’s not clear when code will be merged to mainline, but Collabora said “Pine64 Quartz64 SBC out-of-the-box support is right around the corner” in a recent tweet. In any case, it’s good news there’s active development for mainline Linux on the new Rockchip processors, as that means it will be possible to run the latest version of Linux on RK3566 & RK3568 without having to rely on an often […]
