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

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