|
|
<para>This section describes

|
the most user-visible new or changed features in &os;

since &release.prev;.

In general, changes described here are unique to the &release.branch;

branch unless specifically marked as &merged; features.

<para>Typical release note items
|

document recent security advisories issued after

&release.prev;,

|
new drivers or hardware support, new commands or options,
|
|
major bug fixes, or contributed software upgrades. They may also
|
|
list changes to major ports/packages or release engineering

|
practices. Clearly the release notes cannot list every single
|
|
change made to &os; between releases; this document focuses

|
primarily on security advisories, user-visible changes, and major

architectural improvements.</para>

<title>Kernel Changes</title>
|
|
|
|
<para revision="248508">The use of unmapped VMIO buffers eliminates the need to perform
|
|
TLB shootdown for mapping on buffer creation and reuse, greatly reducing the
|
|
amount of IPIs for shootdown on big-SMP machines and eliminating up to 25-30%
|
|
of the system time on i/o intensive workloads.</para>
|
|
|
|
<para arch="amd64" revision="254466">The maximum amount of memory the &os; kernel
|
|
can address has been increased from 1TB to 4TB.</para>
|
|
|
|
<para>A new &man.cpuset.2; API has been added
|
|
for thread to CPU binding and CPU resource grouping and
|
|
assignment. The &man.cpuset.1; userland utility has been added
|
|
to allow manipulation of processor sets.</para>
|
|
|
|
<para role="merged">The &man.ddb.4; kernel debugger now has an output capture
|
|
facility. Input and output from &man.ddb.4; can now be captured
|
|
to a memory buffer for later inspection using &man.sysctl.8; or
|
|
a textdump. The new <command>capture</command> command controls
|
|
this feature.</para>
|
|
|
|
<para role="merged">The &man.ddb.4; debugger now supports a simple scripting
|
|
facility, which supports a set of named scripts consisting of a
|
|
set of &man.ddb.4; commands. These commands can be managed from
|
|
within &man.ddb.4; or with the use of the new &man.ddb.8;
|
|
utility. More details can be found in the &man.ddb.4; manual
|
|
page.</para>
|
|
|
|
<para role="merged">The kernel now supports a new textdump format of kernel
|
|
dumps. A textdump provides higher-level information via
|
|
mechanically generated/extracted debugging output, rather than a
|
|
simple memory dump. This facility can be used to generate brief
|
|
kernel bug reports that are rich in debugging information, but
|
|
are not dependent on kernel symbol tables or precisely
|
|
synchronized source code. More information can be found in the
|
|
&man.textdump.4; manual page.</para>
|
|
|
|
<para>Kernel support for M:N threading has been removed. While
|
|
the KSE (Kernel Scheduled Entities) project was quite successful
|
|
in bringing threading to FreeBSD, the M:N approach taken by the
|
|
KSE library was never developed to its full potential.
|
|
Backwards compatibility for applications using KSE threading
|
|
will be provided via &man.libmap.conf.5; for dynamically linked
|
|
binaries. The &os; Project greatly appreciates the work of
|
|
&a.julian;, &a.deischen;, and &a.davidxu; on KSE support.</para>
|
|
|
|
<para>The &os; kernel now exports information about certain kernel
|
|
features via the <varname>kern.features</varname> sysctl tree.
|
|
The &man.feature.present.3; library call provides a convenient
|
|
interface for user applications to test the presence of
|
|
features.</para>
|
|
|
|
<para arch="amd64">The &os; kernel now has support for large
|
|
memory page mappings (<quote>superpages</quote>).</para>
|
|
|
|
<para arch="amd64,i386,ia64,powerpc" role="merged">The ULE

|
|
<para arch="amd64,i386" revision="240135">Support was added for

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

<para arch="amd64,i386" revision="255524">Paravirtualized drivers which

<para revision="243524">The zio nop-write improvement from Illumos
|
|
was imported into &os;. To reduce I/O, nop-write skips overwriting
|
|
data if the checksum (cryptographically secure) of new data
|
|
matches the checksum of existing data. It also saves space if
|
|
snapshots are in use. This improvement only works only on
|
|
datasets with enabled compression, disabled deduplication and
|
|
sha256 checksums.</para>

<para>ZFS will now compare the checksums of incoming writes to
|
|
the checksum of the existing on-disk data and avoid issuing any
|
|
write I/O for data that has not changed. This will reduce I/O
|
|
as well as space usage because if the old block is referenced
|
|
by a snapshot, both copies of the block are kept even though
|
|
both contain the same data.</para>
