While it's arriving late, FreeBSD 9.1
has been officially released just in time for 2013.
FreeBSD 9.1 has been months behind schedule
, but the FreeBSD 9.1-RELEASE announcement was finally issued yesterday on 30 December.
Key highlights of FreeBSD 9.1 include the Intel GEM/KMS kernel driver that was ported from Linux, the netmap fast user-space packet I/O framework, ZFS improvements from Illumos, the CAM target layer, an optional C++11 stack using LLVM/libc++/libcxxrt, various new hardware drivers, kernel support for the AVX FPU extension, and numerous improvements for IPv6 hardware offloading. The long-awaited Intel KMS support for FreeBSD
is quite exciting though it's a constant challenge of back-porting changes from the Linux kernel. There's also no official Radeon or Nouveau driver KMS/DRM drivers in FreeBSD.
The FreeBSD 9.1 release announcement with more details can be found at FreeBSD.org
. Earlier this month on Phoronix were FreeBSD 9.1 benchmarks against Linux
and other operating systems.
