130 list changes to major ports/packages or release engineering
131 practices. Clearly the release notes cannot list every single
132 change made to &os; between releases; this document focuses
133 primarily on security advisories, user-visible changes, and major

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

191 features via the <varname>kern.features</varname> sysctl tree.

200 scheduler is now the default process scheduler

213 (e.g. Nehalem and newer), but not on the lower-end Atom CPUs.</para>

216 name for the paravirtualization interface developed for the Linux KVM, but
217 since adopted to other virtual machine hypervisors (with the notable exception of Xen).
218 This work brings in a BSD-licensed clean-room implementation of the virtio kernel drivers

460 <para revision="243524">The zio nop-write improvement from Illumos
461 was imported into &os;. To reduce I/O, nop-write skips overwriting
462 data if the (cryptographically secure) checksum of new data
463 matches the checksum of existing data. It also saves space if
464 snapshots are in use. This improvement only works on
465 datasets with enabled compression, disabled deduplication and
466 sha256 checksums. ZFS will now compare the checksums of incoming writes to
467 the checksum of the existing on-disk data and avoid issuing any
468 write I/O for data that has not changed. This will reduce I/O
469 as well as space usage because if the old block is referenced
