99 <para>This section describes
100 the most user-visible new or changed features in &os;

102 In general, changes described here are unique to the &release.branch;
103 branch unless specifically marked as &merged; features.
106 <para>Typical release note items
107 document recent security advisories issued after
109 new drivers or hardware support, new commands or options,
110 major bug fixes, or contributed software upgrades. They may also
111 list changes to major ports/packages or release engineering
112 practices. Clearly the release notes cannot list every single
113 change made to &os; between releases; this document focuses
114 primarily on security advisories, user-visible changes, and major

125 <title>Kernel Changes</title>
127 <para revision="248508">The use of unmapped VMIO buffers eliminates the need to perform
128 TLB shootdown for mapping on buffer creation and reuse, greatly reducing the
129 amount of IPIs for shootdown on big-SMP machines and eliminating up to 25-30%
130 of the system time on i/o intensive workloads.</para>
132 <para arch="amd64" revision="254466">The maximum amount of memory the &os; kernel
133 can address has been increased from 1TB to 4TB.</para>
135 <para>A new &man.cpuset.2; API has been added
136 for thread to CPU binding and CPU resource grouping and
137 assignment. The &man.cpuset.1; userland utility has been added
138 to allow manipulation of processor sets.</para>
140 <para role="merged">The &man.ddb.4; kernel debugger now has an output capture
141 facility. Input and output from &man.ddb.4; can now be captured
142 to a memory buffer for later inspection using &man.sysctl.8; or
143 a textdump. The new <command>capture</command> command controls
146 <para role="merged">The &man.ddb.4; debugger now supports a simple scripting
147 facility, which supports a set of named scripts consisting of a
148 set of &man.ddb.4; commands. These commands can be managed from
149 within &man.ddb.4; or with the use of the new &man.ddb.8;
150 utility. More details can be found in the &man.ddb.4; manual
153 <para role="merged">The kernel now supports a new textdump format of kernel
154 dumps. A textdump provides higher-level information via
155 mechanically generated/extracted debugging output, rather than a
156 simple memory dump. This facility can be used to generate brief
157 kernel bug reports that are rich in debugging information, but
158 are not dependent on kernel symbol tables or precisely
159 synchronized source code. More information can be found in the
160 &man.textdump.4; manual page.</para>
162 <para>Kernel support for M:N threading has been removed. While
163 the KSE (Kernel Scheduled Entities) project was quite successful
164 in bringing threading to FreeBSD, the M:N approach taken by the
165 KSE library was never developed to its full potential.
166 Backwards compatibility for applications using KSE threading
167 will be provided via &man.libmap.conf.5; for dynamically linked
168 binaries. The &os; Project greatly appreciates the work of
169 &a.julian;, &a.deischen;, and &a.davidxu; on KSE support.</para>
171 <para>The &os; kernel now exports information about certain kernel
172 features via the <varname>kern.features</varname> sysctl tree.

181 scheduler is now the default process scheduler

185 the new Intel on-CPU Bull Mountain random number
186 generator, found on IvyBridge and supposedly later CPUs,

193 support. These features are on all Nehalem models and beyond
194 (e.g. Nehalem and newer), but not on the lower-end Atom CPUs.</para>
196 <para revision="227652">&man.virtio.4; support has been added. &man.virtio.4; is the
197 name for the paravirtualization interface developed for the Linux KVM, but
198 since adopted to other virtual machine hypervisors (with the notable exception of Xen).
199 This work brings in a BSD-licensed clean-room implementation of the virtio kernel drivers
200 for disk IO (&man.virtio_blk.4; and &man.virtio_scsi.4;), network IO (&man.vtnet.4;),

445 snapshots are in use. This improvement only works only on
446 datasets with enabled compression, disabled deduplication and

449 <para>ZFS will now compare the checksums of incoming writes to
450 the checksum of the existing on-disk data and avoid issuing any
451 write I/O for data that has not changed. This will reduce I/O
452 as well as space usage because if the old block is referenced
