Devices
IDE / AHCI
Added emulation layer for an ICH-9 AHCI controller (not yet stable). Tested with Linux, OpenBSD, Windows Vista and Windows 7. The AHCI emulation supports NCQ, so multiple read or write requests can be outstanding at the same time.
to use it, use the following command line snippet: -drive id=disk,file=<your image goes here>,if=none -device ahci,id=ahci -device ide-drive,drive=disk,bus=ahci.0
SCSI
Various bug fixes, no new features.
USB
Added USB support for remote wakeup, allowing the guest to suspend the USB bus when idle, which in turn reduces the CPU overhead of an idle machine.
The USB subsystem also got a bunch of patches to prepare it for USB 2.0 support.
virtio
virtio-pci can use ioeventfd for virtqueue notify. On systems that support KVM, the ioeventfd mechanism can be used to make virtqueue notify a lightweight exit by deferring hardware emulation to the iothread and allowing the VM to continue execution. This model is similar to how vhost receives virtqueue notifies. The result of this change is improved performance for userspace virtio devices. Virtio-blk throughput increases especially for multithreaded scenarios and virtio-net transmit throughput increases substantially. Read the commit message for more details.
Various fixes and stabilization for live-migration:
Various virtio-net improvements:
Make tx_timer timeout configurable
Limit number of packets sent per TX flush
Introduce a new bottom half packet TX
Fix cross-endianness support
PCI/PCI Express
Improved PCI Express support and functionalities with the implementation of:
flr (Function Level Reset)
aer (Advanced Error Reporting) and other improvements
A new monitor command to inject errors into the PCI bus: pcie_aer_inject_error
Implementation of Message Signaled Interrupts (MSI/MSI-X) support
Separation of the PCI bridge code from the main PCI code.
Sound
New Intel HD Audio support, adding three new devices:
intel-hda: Intel HD Audio Controller, the PCI device.
hda-duplex: HDA Codec. Attaches to the HDA bus. Supports 16bit stereo, rates 16k -> 96k, playback, recording and volume control (with CONFIG_MIXEMU=y).
hda-output: HDA Codec without recording support. Subset of the hda-duplex codec. Use this if you don't want your guests access your mic.
Usage: add '-device intel-hda -device hda-duplex' to your command line.
Tested guests:
Linux works.
Win7 works.
DOS (mpxplay) works.
WinXP doesn't work.
Real Time Clock
Fix binary/BCD mode switch
Video
Fix cirrus VGA crash with some guests
Fix curses big endian support
Block Drivers
qcow2
Added a writeback metadata cache. This improves performance of scenarios with lots of cluster allocations noticably (e.g. installation or after taking a snapshot), in some benchmarks by a factor of ten or more. Use cache=none or cache=writeback to take advantage from this change.
Copy snapshots out of QCOW2 disk, eg: qemu-img convert -f qcow2 -O qcow2 -s snapshot_name src_img bck_img
Zero-copy read and write operations
Other fixes and code cleanups:
qcow2: Invalidate cache after failed read
block: Allow bdrv_flush to return errors
qcow2: Simplify image creation
qcow2: Fixes unaligned access on IA64
qed
Introduction of the QEMU Enhanced Disk (qed) image format. It is a disk image format that forgoes features found in qcow2 in favor of better levels of performance and data integrity. Due to its simpler on-disk layout, it is possible to safely perform metadata updates more efficiently.
More information about qed: http://wiki.qemu.org/Features/QED
Initial thread discussion: http://lists.nongnu.org/archive/html/qemu-devel/2010-09/msg00310.html
ceph/rbd
Introduction of the new ceph/rbd block driver. RBD is an block driver for the distributed file system Ceph.
More information about ceph: http://ceph.newdream.net/
nbd
Improve qemu-nbd performance by 4400 %. This patch combines the reply header and payload send operation.
Introduce NBD named exports.
Spice
New support for the SPICE protocol. The project main focus is to provide high-quality remote access to QEMU virtual machines. More information about SPICE can be found at the project's web site: http://spice-space.org/
New qxl device. qxl is a paravirtual graphics card. The qxl device is the bridge between the guest and the spice server (aka libspice-server). The spice server will send the rendering commands to the spice client, which will actually render them. The spice server is also able to render locally, which is done in case the guest wants read something from video memory. Local rendering is also used to support display over vnc and sdl. qxl is activated using -vga qxl. qxl supports multihead, additional cards can be added via '-device qxl.
Relevant commits:
spice: core bits
spice: add keyboard
spice: add mouse
spice: simple display
spice: add tablet support
spice: tls support
spice: make compression configurable.
spice: add config options for channel security.
spice: add config options for the listening address
spice: add misc config options
spice: add audio
spice: add qxl device
spice: connection events.
QMP / monitor
TODO: QMP is now stable, except for error reporting?
The work to facilitate the management of QEMU instances has been improved. QMP has received various fixes. Now it is possible to call a traditional monitor command through QMP, in case your application depends on the output or the command is not yet ported to QMP.
New commands:
query-spice / info spice
human-monitor-command
set_password
drive_del
block_resize command, allowing resizing of block devices while qemu is running. For virtio-blk the size is updated automatically when this command is issued on the host. IDE is not supported. For SCSI devices the new size can be updated in Linux guests by doing the following shell command:
echo > /sys/class/scsi_device/0:0:0:0/device/rescan
Tracing
Introduction of platform-independent tracing, more information about it: http://wiki.qemu.org/Features/Tracing
Documentation and tutorial: http://git.qemu.org/qemu.git/plain/docs/tracing.txt
Some relevant commits:
Add trace-events file for declaring trace events
Add a DTrace tracing backend targetted for SystemTAP compatibility
Add LTTng Userspace Tracer backend
Add simple built-in tracing backend
Add stderr trace-event backend:
Support for dynamically enabling/disabling trace events
Specify trace file name
Add trace-file command to open/close/flush trace file
Other stuff
Extend -option-rom command to have additional parameter bootindex
Little endian / big endian MMIO framework. Until now, most devices had special hacks to allow them to work on big and little endian systems (ppc / x86). With that framework, they should mostly work with both and not require and device specific hacks anymore.
"Looks good" from wiz@ and obache@.

Also add a patch for e1000.c NIC to make wm(4) work on NetBSD guest:
---
* Reset EEPROM internal state on CS rise edge,
not SK rise edge during CS is low, per CS pin description in
the FM93C06 EEPROM manual:
"... a rising edge on this signal is required to reset the
internal state-machine to accept a new cycle ..."
Intel's em driver seems to explicitly raise and lower SK output
after CS is negated in em_standby_eeprom() so many other OSes
that use Intel's driver don't have this problem, but I can't find
articles that say the MICROWIRE or EEPROM spec requires such sequence.
* It isn't a good idea to use memset(,0,) to clear EEPROM state values,
so explicitly clear status members and preserve the previous EECD values
---
This patch is also filed as upstream QEMU bugs #581737.
While here, several tweaks in Makefile to appease pkglint.
tap backend work on NetBSD (NetBSD uses an ioctl to get the tap name).
patch-ab: add support for the "select without ATN" to the emulated
esp device. NetBSD's esp(4) uses this command and aborts after a timeout.
While there fix the homepage URL.
Now NetBSD/sparc 5.0.1 boots and runs fine in qemu-system-sparc on a
NetBSD/amd64 host.
Bump pkgrevision.
Unknown why it was using this.
This closes PR 39571 and PR 37786.
Another suggestion is to use pkgsrc's MACHINE_ARCH.
(Not completely tested on DragonFly as this still doesn't build
due to wrong gcc.)
Also note this release is not the latest.
Emulate the speaker port's refresh clock bit. This is supposed
to toggle between 0 and 1<<4 every 15 microseconds. XXX: We use
gettimeofday() in the real machine instead of a monotonic clock
in the virtual machine, and we are a bit sloppy about the 15
microseconds. This should be good enough for crude loops that
measure approximate delays by counting how often this line toggles.

Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.

QEMU is a FAST! processor emulator using dynamic translation to achieve
good emulation speed, QEMU has two operating modes:
* Full system emulation. In this mode, QEMU emulates a full system
(for example a PC), including a processor and various peripherals.
It can be used to launch different Operating Systems without rebooting
the PC or to debug system code.
* User mode emulation (Linux host only). In this mode, QEMU can launch
Linux processes compiled for one CPU on another CPU. It can be used
to launch the Wine Windows API emulator or to ease cross-compilation
and cross-debugging.

It's nice to see NetBSD/x86 running perfectly with QEMU!
