OpenBSD 6.0 发布多项功能改进增强

OpenBSD 6.0 发布了，OpenBSD是一个从NetBSD衍生出来的类Unix操作系统。专案领导人Theo de Raadt在1995年]发起了OpenBSD专案，希望创造一个注重安全的操作系统，此外OpenBSD也以高品质的文件、坚持开放程式码以及严格的软件授权著名。OpenBSD的吉祥物是河豚。

该版本改进如下：

New/extended platforms:

armv7:
- EFI bootloader added, kernels are now loaded from FFS instead of FAT or EXT filesystems, without U-Boot headers.
- A single kernel and ramdisk are now used for all SoCs.
- Hardware is dynamically enumerated via Flattened Device Tree (FDT) instead of via static tables based on board id numbers.
- Miniroot installer images include U-Boot 2016.07 with support for EFI payloads.
vax:
- Removed.
Improved hardware support, including:
- New bytgpio(4) driver for the Intel Bay Trail GPIO controller.
- New chvgpio(4) driver for the Intel Cherry View GPIO controller.
- New maxrtc(4) driver for the Maxim DS1307 real time clock.
- New nvme(4) driver for the Non-Volatile Memory Express (NVMe) host controller interface.
- New pcfrtc(4) driver for the NXP PCF8523 real time clock.
- New umb(4) driver for the Mobile Broadband Interface Model (MBIM).
- New ure(4) driver for RealTek RTL8152 based 10/100 USB Ethernet devices.
- New utvfu(4) driver for audio/video capture devices based on the Fushicai USBTV007.
- The iwm(4) driver now supports Intel Wireless 3165 and 8260 devices, and works more reliably in RAMDISK kernels.
- Support for I2C HID devices with GPIO signalled interrupts has been added to dwiic(4).
- Support for larger bus widths, high speed modes, and DMA transfers has been added to sdmmc(4), rtsx(4), sdhc(4), and imxesdhc(4).
- Support for EHCI and OHCI compliant USB controllers on Octeon II SoCs.
- Many USB device drivers have been enabled on OpenBSD/octeon.
- Improved support for hardware-reduced ACPI implementations.
- Improved support for ACPI 5.0 implementations.
- AES-NI crypto is now done without holding the kernel lock.
- Improved AGP support on PowerPC G5 machines.
- Added support for the SD card slot in Intel Bay Trail SoCs.
- The ichiic(4) driver now ignores the SMBALERT# interrupt to prevent an interrupt storm with buggy BIOS implementations.
- Device attachment problems with the axen(4) driver have been fixed.
- The ral(4) driver is more stable under load with RT2860 devices.
- Problems with dead keyboards after resume have been fixed in the pckbd(4) driver.
- The rtsx(4) driver now supports RTS522A devices.
- Initial support for MSI-X has been added.
- Support MSI-X in the virtio(4) driver.
- Added a workaround for hardware DMA overruns to the dc(4) driver.
- The acpitz(4) driver now spins the fan down after cooling if ACPI uses hysteresis for active cooling.
- The xhci(4) driver now performs handoff from an xHCI-capable BIOS correctly.
- Support for multi-touch input has been added to the wsmouse(4) driver.
- The uslcom(4) driver now supports the serial console of Aruba 7xxx wireless controllers.
- The re(4) driver now works around broken LED configurations in APU1 EEPROMs.
- The ehci(4) driver now works around problems with ATI USB controllers (e.g. SB700).
- The xen(4) driver now supports domU configuration under Qubes OS.
