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

214 name for the paravirtualization interface developed for the Linux KVM, but
215 since adopted to other virtual machine hypervisors (with the notable exception of Xen).
