For a comprehensive list, see the changelog leading to 4.9. New/extended platforms: OpenBSD/amd64 and OpenBSD/i386: Enabled NTFS by default (read-only) on GENERIC kernels. Enabled the vmt(4) driver by default for VMWare tools support as a guest. SMP kernels can now boot on machines with up to 64 cores. Maximum allocation size for i386 bumped to 2G. Handle >16 disks when searching for kernel boot device. Added support for AES-NI instructions found in recent Intel processors. Further improvements in suspend and resume. Processes are now switched to TSS per cpu on the amd64 platform, resulting in removal of the old limit of ~4000 processes. OpenBSD/hppa: Multiprocessor support. OpenBSD/loongson and OpenBSD/sgi: All MIPS64 based platforms now use MI softfloat code, which implements all MIPS IV specified floating point operations. OpenBSD/sparc64: The vdsp(4) driver now supports the vDisk 1.1 protocol, allowing Solaris to run on top of an OpenBSD control domain. Improved hardware support, including: New vte(4) driver for RDC R6040 10/100 Ethernet devices. New rdcphy(4) driver for RDC Semiconductor R6040 10/100 Ethernet PHY. New rsu(4) driver for Realtek RTL8188SU/RTL8191SU/RTL8192SU USB IEEE 802.11b/g/n wireless devices. New urtwn(4) driver for Realtek RTL8188CU/RTL8192CU USB IEEE 802.11b/g/n wireless devices. New utwitch(4) driver for YUREX USB twitch/jiggle of knee sensor. Support for AR9271, AR9280+AR7010 and AR9287+AR7010 USB IEEE 802.11a/g/n wireless adapters has been added to athn(4).

MCLGETI support has been added to xl(4). Support for low latency interrupt modulation has been added to ix(4). Port multiplier support has been added to ahci(4) and sili(4). Support for Sun XVR-300 graphics has been added to radeonfb(4). Added workaround for BCM5906 A0/1/2 controller silicon bug in bge(4). ugen(4) can now be attached along with other drivers to multifunction devices. umodem(4) now supports more devices. umsm(4) now supports more mobile broadband devices. Support for more image processing controls was added to uvideo(4). Generic network stack improvements: Reworking of the MCLGETI livelock algorithm to improve forwarding and host performance under high network load. Added support for socket splicing; sockets can be t |
