129 list changes to major ports/packages or release engineering
130 practices. Clearly the release notes cannot list every single

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

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