New &man.jail.8; parameters + allow.mount.devfs, + allow.mount.nullfs, and + allow.mount.zfs to control the per-jail + capabilities have been added. All of them are disabled by + default. + + A new &man.loader.8; tunable + kern.eventtimer.activetick has been added. + This tunable is to specify whether each hardclock tick should + be run on every active CPU or only one. Setting it to + 0, the number of interrupts can be reduced + on SMP machines. The default value is + 1. + + The &man.posix.fadvise.2; system call + has been implemented. This is a function similar to + &man.madvise.2; except that it operates on a file descriptor + instead of a memory region. + + The &man.filemon.4; pseudo device has + been added. This allows a process to collect file operations + data of its children. + + The &man.sysctl.8; variable + kern.stop_scheduler_on_panic is now set to + 1 by default. + + &os;/powerpc64 now + supports kernel profiling by using &man.kgmon.8;. + + The &os; Linux ABI compatiblity layer + now supports linux_fadvice64() and + linux_fadvice64_64() system call. + + The default value of the &man.loader.8; + tunable hw.memtest.tests is now + automatically set to 0 when &os; is running + on a virtual machine. + + A new &man.loader.8; tunable + kern.msgbuf_show_timestamp has been added. + When this is enabled, timestamp is added to each line of the + system message buffer. The default value is + 0 (disabled). + + The &man.null.4; and &man.zero.4; pseudo + device driver now supports non-blocking mode via &man.fcntl.2; + system call. + + The &os; &man.sched.ule.4; scheduler has + been improved on CPU load balancing of SMT (Simultaneous + MultiThreading) CPUs. It gives 10-15% performance improvement + when the number of threads is lesser than the number of + logical CPUs. + + PREEMPTION kernel option is + now enabled in GENERIC kernel. + + A new &man.sysctl.8; variable + security.bsd.unprivileged_idprio has been + added. This variable controls whether non-root users can set + an idle priority or not. This is disabled by default. + + The &man.splash.4; screen interface now + supports ASCII art in TheDraw + format. + + + Boot Loader Changes + + The &man.boot0cfg.8; utility now + supports configuration of PXE boot via + boot0 boot block temporarily on the + next boot. The slice number 6 or a + keyword PXE can be specified to enable + PXE boot in the option. + + The &os; &man.boot.8; block now + supports /boot/config in addition to + /boot.config as the boot block + parameter file. When both of them exist, the former will be + used. + + The gptboot boot + block now reads the backup GPT header from the last LBA only + when the primary GPT header and tables are invalid. This + mitigates interoperability issues with some &man.geom.4; + providers like MIRROR which use the last + LBA for the metadata. + + The zfsboot boot + block and zfsloader supports + filesystems within a ZFS storage pool. In + zfsloader, ZFS device name format now + is + zfs:pool/fs + and fully qualified file path is + zfs:pool/fs:/path/to/file. + The zfsboot accepts kernel/loader name + in a format + pool:fs:path/to/file + or, as before, + pool:path/to/file. + In the latter case a default filesystem is used (the pool + root or bootfs property). The + zfsboot passes GUIDs of the selected + storage pool and dataset to zfsloader + to be used as its defaults. + + The &os;/sparc64 now + supports booting from ZFS via zfsboot boot block and + zfsloader. For example, the following commands create a + mirrored storage pool rpool consisting of + da0a and da0b and + configure the storage pool as the root filesystem: + + &prompt.root; gpart create -s vtoc8 da0 +&prompt.root; gpart add -t freebsd-zfs -s 10g da0 +&prompt.root; gpart add -t freebsd-swap -s 10g da0 +&prompt.root; gpart add -t freebsd-zfs -s 10g da0 +&prompt.root; zpool create rpool mirror da0a da0b +&prompt.root; zpool set bootfs=rpool rpool +&prompt.root; zpool export rpool +&prompt.root; gpart bootcode -p /boot/zfsboot da0 +&prompt.root; sysctl kern.geom.debugflags=0x10 +&prompt.root; dd if=/boot/zfsloader of=/dev/da0a bs=512 oseek=1024 conv=notrunc +&prompt.root; dd if=/boot/zfsloader of=/dev/da0b bs=512 oseek=1024 conv=notrunc +&prompt.root; zpool import rpool +&prompt.root; cp -p /boot/zfs/zpool.cache /rpool/boot/zfs/zpool.cache +&prompt.root; zfs set mountpoint=/ rpool + + + + Hardware Support + + The &man.abtn.4; + driver, which supports ADB keyboards found on Apple laptops, + has been added. + + A workaround for Erratum + 721 for AMD Processor Family 10h and 12h has been + implemented. Under a highly specific and detailed set of + internal timing conditions, the processor may incorrectly + update the stack pointer after a long series of push and/or + near-call instructions, or a long series of pop and/or + near-return instructions. + + The atibl(4) driver, + which supports backlight control of ATI graphics chips on + PowerBooks and iBooks, has been added. + + The &man.acpi.wmi.4; driver now + supports attaching multiple instances. + + The adm1030(4) driver + for G4 MDD fan now shows its PWM parameter in the device + &man.sysctl.8; variable. + + The cesa(4) driver for + Marvell crypto engine and security accelerator has been + added. + + The &man.hwpmc.4; + driver now supports PowerPC G4+ (MPC745x/MPC744x). + + The &man.hwpmc.4; + driver now supports Intel Sandy Bridge + microarchitecture. + + The &man.hwpmc.4; driver now supports + software events. Simultaneous usage of software PMC and + hardware PMC is allowed. + + The pcf8563(4) driver for NXP + (Philips) PCF8563 RTC has been added. + + &os;/powerpc now + supports PWM-controlled fans found on PowerMac SMU (System + Management Unit). + + &os;/arm now supports Atmel + SAM9XE family of microcontrollers. + + The following &man.sysctl.8; + variables have been added: kern.proc.env + for environment strings, kern.proc.auxv + for ELF auxiliary vectors from a process stack, + kern.proc.groups for process groups, + kern.proc.rlimit for process resource + limits, and kern.proc.ps_strings for + ps_strings location, kern.proc.osrel for + osreldate for process binary. + + The &man.usb.4; driver now + handles suspend and resume correctly with no need of reloading + the kernel module. + + A bug in the &man.xhci.4; (USB 3.0) + driver has been fixed. It did not work with USB 3.0 + hubs. + + The &man.viawd.4; driver, which + supports watchdog timer found in VIA south bridge (VT8251, + CX700, VX800, VX855, VX900), has been added. + + The &man.wbwd.4; driver, which + supports watchdog timer found in Winbond Super I/O chips, + has been added. + + + Multimedia Support + + The drm2(4) Intel GPU driver, + which supports GEM, KMS, and works with new generations of + GPUs such as IronLake, SandyBridge, and IvyBridge, has been + added. The &man.agp.4; dirver now supports SandyBridge + and IvyBridge CPU northbridges. + + The &man.snd.hda.4; driver has been + updated. It now supports HDMI, new volume control, + automatic recording source selection, runtime + reconfigureation, more then 4 PCM devices on a controller, + multichannel recording, additional playback/record + streams, higher bandwidth, and more informative device + names. + + The &man.snd.hdspe.4; driver has + been added. This supports RME HDSPe AIO and RayDAT sound + cards. + + GPL-licensed + headers in the &man.snd.emu10kx.4;, &man.snd.maestro3.4;, + and &man.snd.csa.4; drivers have been replaced with + BSD-licensed one. These drivers are now fully + BSD-licensed and included in GENERIC + kernel on &os;/amd64 and &os;/i386. + + + + Network Interface Support + + A bug in &man.ae.4; driver which could + prevent from working under certain conditions has been + fixed. + + The &man.axe.4; driver now supports + TX/RX checksum offloading support for ASIX AX88772B + controller. + + The &man.bce.4; driver has been improved: + + + + Unnecessary link up/down has + been eliminated. + + + + A bug has been fixed. It could + prevent IPMI from working when the interface was + marked as down. + + + + It now supports remote PHYs, + which allow the controller to perform MDIO type accesses + to a remote transceiver by using message pages defined + through MRBE (MultiRate Backplane Ethernet). This is + found on machines such as Dell PowerEdge M610 + Blade. + + + + The &man.bge.4; and brgphy(4) driver have been + improved: + + + + A bug which could prevent the + DMA functionality from working correctly, has been + fixed. + + + + It now works with PCI-X BCM 5704 + controller that connected to AMD-8131 PCI-X bridge. + + + + It now supports + BCM 5720 and BCM 5720C PHY, and BCM 57780 1000BASE-T + media interface. + + + + It now supports a &man.loader.8; + tunable + dev.bge.N.msi + to control the use of MSI. The default value is + 1 (enabled). + + + + The &man.cxgbe.4; and + &man.cxgb.4; driver has been updated to firmware version + 1.5.2.0. This now supports device configuration via a + plain text configration file, IPv6 hardware checksumming, + IPv6 TSO and LRO, loadfw command in the + cxgbetool(8) utility which allows to install a firmware to + the card, &man.sysctl.8; variables under + dev.t4nex.N.misc + for various information. + + The &man.dc.4; driver now supports + NVIDIA (ULi) M5261/M5263 PCI FastEthernet controllers, which + are found on ULi M1563 South Bridge and M1689 Bridge. + + The &man.et.4; driver + now works on all platfomrs. A bug which could prevent + &man.altq.4; support from working has been fixed. A new + &man.sysctl.8; variables under + dev.et.N.stats + have been added for hardware MAC statistics. + + The &man.igb.4; driver has been + updated to version 2.3.4. It now supports newer i210/i211 + devices. + + The &man.iwn.4; driver now + supports Intel Centrino Wireless-N + WiMAX 6150 and + Wireless-N 100/130 series. + + The &man.miibus.4; bus driver now + supports device hints + hint.miibus.N.phymask + for PHY addresses being probed. This is useful to manually + probe PHYs which do not implement basic register set of + IEEE 802.3. Also, the &man.miibus.4; driver has been + changed to a hinted bus, allowing to add child devices via + hints and to set their attach arguments in addition to + automatically-probed PHYs. + + The &man.msk.4; driver now uses 64-bit + DMA addressing on 64-bit platforms. + + The &man.mxge.4; driver has been + updated to firmware version 1.4.55 from Myricom. + + The nsphyter(4) driver now supports + National DP83849. + + The &man.oce.4; driver, which + supports Emulex OneConnect 10Gbit Ethernet card, has been + added. + + The &man.ral.4; driver now supports + Ralink RT2800 and RT3000 chipsets. + + The &man.re.4; driver now + supports RTL8411 PCIe Gigabit Ethernet controller.

These allow to control initial timeout, idle time, + idle resend interval, and idle send count in a per-socket + basis. + + + + Disks and Storage + + The &man.arcmsr.4; driver has been + updated to version 1.20.00.25. + + The &man.ahci.4; driver now supports a + new &man.loader.8; tunable hw.ahci.force. + This controls whether it attempts to attach an AHCI-capable + device even if it is configured to use legacy emulation. + This is enabled by default. + + The new &man.cam.4;-based &man.ata.4; + driver now supports old &man.loader.8; tunables, + hw.ata.ata_dma and + hw.ata.atapi_dma, for backward + compatibility. + + The &man.cam.4; driver now supports + SEMB (SATA Enclosure Management Bridge) devices, which are + equivalent to the SCSI SES/SAF-TE devices. + + A new &man.sysctl.8; variable + kern.cam.pmp.hide_special has been added. + This controls whether special PMP ports such as PMP (Port + MultiPlier) configuration or SEMB (SATA Enclosure Management + Bridge) will be exposed or hidden. The default value is + 1 (hidden). + + The ctl(4) driver, which supports + &man.cam.4; Target Layer and &man.ctladm.8;, a userland + control utility, have been added. ctl(4) is a disk and + processor device emulation subsystem supporting tagged + queueing, SCSI task attribute, SCSI implicit command + ordering, full task management, multiple ports, multiple + simultaneous initiators, multiple simultaneous backing + stores, mode sense/select, and error injection + support. + + The &man.cd.4; driver now supports + Audio CDs in the same way as &man.acd.4; did. It will + report 2352-byte sector to &man.geom.4; subsystem and use + READ CD command for reading the data. + This fixes an interoperability issue with multimedia/vlc. + + The &man.da.4; driver now supports + BIO_DELETE. To select the method, a new + &man.sysctl.8; variable + kern.cam.da.N.delete_method + has been added for each device instance. The following + values are supported: + + + + + + Value + Method + + + + + + NONE + no provisioning support reported by the device + + + + DISABLE + provisioning support was disabled because of errors + + + + ZERO + WRITE SAME (10) command to write zeroes + + + + WS10 + WRITE SAME (10) command with UNMAP bit set + + + + WS16 + use WRITE SAME (16) command with UNMAP bit set + + + + UNMAP + use UNMAP command (equivalent of the ATA DSM TRIM command) + + + + + + When it was NONE, the device did not + report the logical block provisioning support via respective + VPD pages. One can set a specific method for testing and it + will be disabled automatically when not supported on the + device. + + The MIRROR + &man.geom.4; class now supports + BIO_DELETE. This means + TRIM command will be issued on the + supported devices when deleting data. + + The + MULTIPATH &man.geom.4; class has + been updated. It now supports Active/Active mode, + Active/Read mode as hybrid of Active/Active and + Active/Passive, keeping a failed path without removing the + geom provider, manual configuration without on-disk + metadata, and add, + remove, fail, + restore, configure + subcommands in &man.gmultipath.8; utility to manage the + configured paths. + + The + PART_LDM &man.geom.4; class has + been added. This partition scheme supports for Logical Disk + Manager, which is also known as dynamic volumes in Microsoft + Windows NT. Note that JBOD, RAID0, and RAID5 volumes are + not supported yet. + + PART_MBR + &man.geom.4; class now allows a primary or extended Linux + swap partition to be used as the system dump device. + + The + RAID &man.geom.4; class is now + included in GENERIC kernel. + + The RAID + &man.geom.4; class now supports disks with over 2TB capacity + for Intel metadata format. + + The RAID + &man.geom.4; class now supports DDF metadata format, which + is defined in the SNIA Common RAID Disk Data Format + Specification v2.0. + + The + UNCOMPRESS &man.geom.4; class and + the &man.mkulzma.8; utility have been added. This class + supports lzma compressed images like + UZIP &man.geom.4; class and the + &man.mkuzip.8; utility. + + The &man.hpt27xx.4; + dirver has been added. This supports HighPoint RocketRAID + 27xx-based SAS 6Gb/s HBA. + + The &man.isci.4; + driver, which supports the integrated SAS controller in the + Intel C600 (Patsburg) chipset, has been added. + + Bugs in &man.isp.4; target mode have + been fixed. + + The &man.ixgbe.4; driver now supports + Intel X540 adapter. + + A bug in &man.mfi.4; driver has been + fixed. It could cause some inconsistency due to missing of + interrupt acknowledge and output the following log + message: + + mfi0: COMMAND 0xffffffXXXXXXXXXX TIMEOUT AFTER XX SECONDS + + The &man.mfi.4; driver now + supports single-message MSI, and Drake Skinny and + ThunderBolt cards. The &man.loader.8; tunable + hw.mfi.msi has been added and it is + enabled by default. + + The &man.mps.4; driver + has been updated to version 14.00.00.01-fbsd. This now + supports Integrated RAID, WarpDrive controllers, WRITE12 and + READ12 for direct I/O, SCSI protection information (EEDP), + Transport Level Retries (TLR) for tape drives, and LSI's + userland utility. + + A bug in the &man.mpt.4; driver has + been fixed. It could attempt to attach MegaRAID cards which + should be handled by the &man.mfi.4; driver. + + The &man.usb.4; storage device driver + now enables power save mode by default. + + + + File Systems + + The &os; NFS filesystem has been improved: + + + + It now supports a timeout on + positive name cache entries on the client side. A new + mount option nametimeo has been added + and set to 60 (in second) by + default. + + + + A memory leak when a ZFS volume is + exported via the &os; NFS server has been fixed. + + + + A bug has been fixed. When a + process writes to an mmap-backed file on an NFS + filesystem, flushing changes to the data could fail + under some circumstances such as errors due to + permission mismatch and this failure could not detected + as an error. A new &man.sysctl.8; variable + vfs.nfs.nfs_keep_dirty_on_error has + been added to control the behavior on the client side + related to this issue. When this is set to + 1, the pages where a write operation + failed are kept dirty. The default value is set to + 0. + + + + The &man.nfsv4.4; filesystem now + supports a new &man.sysctl.8; variable + vfs.nfsd.disable_checkutf8. This + disables the check for a UTF-8 compliance in the + filenames. This is disabled by default. Note that + enabling this may help some interoperability issue but + results in an NFSv4 server that is non-RFC 3530 + compliant. + + + + The &man.tmpfs.5; filesystem is not an + experimental implementation anymore. + + The &man.tmpfs.5; filesystem now + supports a new &man.sysctl.8; variable + vfs.tmpfs.memory_reserved to set amount + of required free pages when &man.tmpfs.5; attempts to + allocate a new node. + + &os; ZFS filesystem has been + updated by merging improvements in illumos project. The + following changes are made: + + + New properties, clones and + written, have been added. + + &man.zfs.8; send command + now reports estimated size of the stream. + + &man.zfs.8; destroy command + now reports estimatated space which would be reclaimed when + flag is specified. + + &man.zfs.8; get command now + supports + flag to specify the data type. + + + A simple script + zfsboottest.sh has been added to the + source tree. This checks if the system is configured + correctly when using ZFS as the root filesystem. The script + is located at + /usr/src/tools/tools/zfsboottest.sh and + it uses zfsboottest binary program in the + same directory. + + The binary program can be built and installed by the + following command: + + &prompt.root; cd /usr/src/tools/tools/zfsboottest +&prompt.root; make +&prompt.root; make install + + After that, the following cmmand can be used to check the + system. poolname is the ZFS + storage pool name to boot: + + &prompt.root; sh /usr/src/tools/tools/zfsboottest/zfsboottest.sh poolname + + The &man.sysctl.8; variable + vfs.zfs.txg.timeout has been changed from + read-only to writable one. + + + *** DIFF OUTPUT TRUNCATED AT 1000 LINES ***
