On the same day as Ubuntu 22.10, Theo de Raadt released the latest version of the Unix-like operating system OpenBSD 7.2.
OpenBSD 7.2 now supports Ampere Altra Arm server processors. Various BSDs have been working hard to support Ampere Altra after the great success of Ampere Altra on Linux, and the acceptance of Altra/Altra Max in the market by various public cloud service providers and other organizations. OpenBSD 7.2 also includes initial support for the Apple M2 chip, with reverse engineering and driver writing in parallel with the work of Linux developers on Apple M1/M2 support. In OpenBSD 7.2, the exciting Arm support work also includes preliminary support for Lenovo ThinkPad X13s Arm notebooks and other hardware using high-end Qualcomm Snapdragon 8cx Gen 3 chips.
In addition to the initial support for Apple M2 and Ampere Altra, some other OpenBSD 7.2 changes include:
- Some different SMP kernel improvements.
- New hardware drivers for various Apple, Qualcomm, SiFive, StarFive, and Allwinner ASICs/IP blocks.
- Supports Intel AX210 / AX211 WiFi chipset.
- Privilege separation has been added to more components and various other security improvements.
- Updated DRM display driver support according to Linux 5.15.69 and enabled Intel DRM driver support for Alder Lake and Raptor Lake.
- Supports up to 256 CPU cores for OpenBSD ARM64 builds.
- Various CPU frequency scaling improvements.
- Enable kstat in the kernel, exporting kernel statistics to be read by the kstat tool.
