OpenBSD 8.0 Ships With Intel Arc Support and a Larger Kernel Address Space

OpenBSD 8.0, the project's 61st release, adds Intel Arc graphics support, a 512 GB kernel virtual address space on AMD64, ARM64 hibernation and a new RPKI-to-router daemon, while founder Theo de Raadt says the project's security record remains intact.

The release keeps to a semiannual schedule that the project has followed since 1996. OpenBSD began more than 30 years ago as a fork of NetBSD and has since become one of the most security-conscious operating systems in active development, Ars Technica reported on 20 October.

Much of the change in 8.0 concerns hardware and memory support. The release adds support for Intel Arc A-Series graphics cards, known as DG2 or Alchemist. On AMD64, the kernel virtual address space grows from 4 GB to 512 GB, which allows the system to map more than 4 GB of video memory. ARM64 systems gain hibernation support.

The release newsletter cited by Ars Technica also lists a new RPKI-to-router daemon, rtrd(8), and several RISC-V improvements, including kernel support for the "V" vector extension and support for Advanced Interrupt Architecture. Wireless network drivers received additions and fixes, among them 802.11n and 40 MHz channel support for the qwx(4) driver.

Virtualization changes appear in both the guest and host layers. A guest virtual machine can now be given up to 64 virtual CPUs, and the vmm/vmd virtualization stack received further improvements. LibreSSL 4.4.0 and OpenSSH 10.6 are included with security and internal changes.

The announcement follows the pattern of previous OpenBSD releases, in which a broad set of driver, kernel and userland updates ships alongside the bundled cryptographic and remote-access tools. De Raadt's message centred on the project's long-standing claim about the number of remotely exploitable flaws in a default installation, a figure the project has cited for years.
