139 <title>Kernel Changes</title>
141 <para revision="248508">The use of unmapped VMIO buffers
142 eliminates the need to perform TLB shootdown for mapping on
143 buffer creation and reuse, greatly reducing the amount of IPIs
144 for shootdown on big-SMP machines and eliminating up to 25-30%
145 of the system time on i/o intensive workloads.</para>
147 <para arch="amd64" revision="254466">The maximum amount of memory
148 the &os; kernel can address has been increased from 1TB to
151 <para>A new &man.cpuset.2; API has been added for thread to CPU
152 binding and CPU resource grouping and assignment. The
153 &man.cpuset.1; userland utility has been added to allow
154 manipulation of processor sets.</para>
156 <para role="merged">The &man.ddb.4; kernel debugger now has an
157 output capture facility. Input and output from &man.ddb.4; can
158 now be captured to a memory buffer for later inspection using
159 &man.sysctl.8; or a textdump. The new
160 <command>capture</command> command controls this feature.</para>
162 <para role="merged">The &man.ddb.4; debugger now supports a simple
163 scripting facility, which supports a set of named scripts
164 consisting of a set of &man.ddb.4; commands. These commands can
165 be managed from within &man.ddb.4; or with the use of the new
166 &man.ddb.8; utility. More details can be found in the
167 &man.ddb.4; manual page.</para>
169 <para role="merged">The kernel now supports a new textdump format
170 of kernel dumps. A textdump provides higher-level information
171 via mechanically generated/extracted debugging output, rather
172 than a simple memory dump. This facility can be used to
173 generate brief kernel bug reports that are rich in debugging
174 information, but are not dependent on kernel symbol tables or
175 precisely synchronized source code. More information can be
176 found in the &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.

211 Nehalem and newer), but not on the lower-end Atom CPUs.</para>

214 &man.virtio.4; is the name for the paravirtualization
215 interface developed for the Linux KVM, but since adopted to
216 other virtual machine hypervisors (with the notable exception
217 of Xen). This work brings in a BSD-licensed clean-room
218 implementation of the virtio kernel drivers for disk IO
219 (&man.virtio_blk.4; and &man.virtio_scsi.4;), network IO
220 (&man.vtnet.4;), memory ballooning (&man.virtio_balloon.4;),
