Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.
Therefore, it should be safe to just drop it from curl's protocol list.
[Jeff Cody: Below is additional summary pulled, with some rewording,
from followup emails between Max and Markus, to explain what
worked and what didn't]
TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero. By default,
that readahead size is 256KB.
Reads starting at a non-zero offset would also have returned data from a
zero offset. It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.
In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.

Filter-rewriter is a part of COLO project.
It will rewrite some of secondary packet to make
secondary guest's tcp connection established successfully.
In this module we will rewrite tcp packet's ack to the secondary
from primary,and rewrite tcp packet's seq to the primary from
secondary.
usage:

In COLO-compare, we do packet comparing job.
Packets coming from the primary char indev will be sent to outdev.
Packets coming from the secondary char dev will be dropped after comparing.
colo-comapre need two input chardev and one output chardev:

outdev=chardev3-id

QEMU compiles a list of data directories from various sources. When
consuming a QEMU binary it's useful to be able to get this list of
data directories: a primary reason is so you can list what BIOSes or
keymaps ship with this version of QEMU. However without reproducing
the method that QEMU uses internally, it's not possible to get the
list of data directories.
This commit adds a simple '-L help' option that just lists out the
data directories as qemu calculates them:
$ ./x86_64-softmmu/qemu-system-x86_64 -L help
/home/rjones/d/qemu/pc-bios
/usr/local/share/qemu
$ ./x86_64-softmmu/qemu-system-x86_64 -L /tmp -L help

FW CFG's primary user is QEMU, which uses it to expose configuration
information (in the widest sense) to Firmware. Thus the name FW CFG.
FW CFG can also be used by others for their own purposes. QEMU is
merely acting as transport then. Names starting with opt/ are
reserved for such uses. There is no provision, however, to guide safe
sharing among different such users.
Fix that, loosely following QMP precedence: names should start with
opt/RFQDN/, where RFQDN is a reverse fully qualified domain name you
control.
Based on a more ambitious patch from Michael Tsirkin.

This patches makes input-linux use -object instead of a new command line
switch. So, instead of the switch ...
-input-linux /dev/input/event$nr
... you must create an object this way:
-object input-linux,id=$name,evdev=/dev/input/event$nr
Bonus is that you can hot-add and hot-remove them via monitor now.

When debugging big programs or system emulation sometimes you want both
the verbosity of cpu,exec et all but don't want to generate lots of logs
for unneeded stuff. This patch adds a new option -dfilter which allows
you to specify interesting address ranges in the form:
-dfilter 0x8000..0x8fff,0xffffffc000080000+0x200,...
Then logging code can use the new qemu_log_in_addr_range() function to
decide if it will output logging information for the given range.

This patch adds parameters to manage some new options in the qemu -net
command.
Slirp IPv6 address, network prefix, and DNS IPv6 address can be given in
argument to the qemu command.
Defaults parameters are respectively fec0::2, fec0::, /64 and fec0::3.

This patch adds support for reading input events directly from linux
evdev devices and forward them to the guest. Unlike virtio-input-host
which simply passes on all events to the guest without looking at them
this will interpret the events and feed them into the qemu input
subsystem.
Therefore this is limited to what the qemu input subsystem and the
emulated input devices are able to handle. Also there is no support for
absolute coordinates (tablet/touchscreen). So we are talking here about
basic mouse and keyboard support.
The advantage is that it'll work without virtio-input drivers in the
guest, the events are delivered to the usual ps/2 or usb input devices
(depending on what the machine happens to have). And for keyboards
qemu is able to switch the keyboard between guest and host on hotkey.
The hotkey is hard-coded for now (both control keys), initialy the
guest owns the keyboard.
Probably most useful when assigning vga devices with vfio and using a
physical monitor instead of vnc/spice/gtk as guest display.
Usage: Add '-input-linux /dev/input/event<nr>' to the qemu command
line. Note that udev has rules which populate /dev/input/by-{id,path}
with static names, which might be more convinient to use.

With this property, users can control if this filter is 'on'
or 'off'. The default behavior for filter is 'on'.
For some types of filters, they may need to react to status changing,
So here, we introduced status changing callback/notifier for filter class.
We will skip the disabled ('off') filter when delivering packets in net layer.

Migration of pseries-2.3 doesn't have configuration section. Unfortunately,
QEMU 2.4/2.4.1/2.5 are buggy and always stream and expect the configuration
section, and break migration both ways.
This patch introduces a property which allows to enforce a configuration
section for machines who don't have one.
It can be set at startup:
-machine enforce-config-section=on
or later from the QEMU monitor:
qom-set /machine enforce-config-section on
It is up to the tooling to set or unset this property according to the
version of the QEMU at the other end of the pipe.

This adds support for dma-buf passing to spice. This makes virtio-gpu
with 3d acceleration work with spice.
Workflow:
* virglrenderer renders the guest command stream into a texture.
* qemu exports the texture as dma-buf and passes on that dma-buf
to spice-server.
* spice-server passes the dma-buf to spice-client, using unix
socket file descriptor passing.
* spice-client asks the window systems composer to render the
dma-buf to the screen.
Requires cutting edge spice (server) and spice-gtk (client) builds,
from git master branch.
Also requires libvirt managing your qemu instance, and using
"virt-viewer --attach $guest". libvirt will connect spice-server and
spice-client using unix sockets instead of tcp sockets then, which
is required for file descriptor passing.
Works for the local case (spice server and client on the same machine)
only. Supporting remote too is planned (by feeding the dma-bufs into
gpu-assisted video encoder), but not there yet.
gl mode is turned off by default, use "-spice gl=on,$otherargs" to
enable it.

The Microsoft spec about the SLIC and MSDM ACPI tables at
<http://go.microsoft.com/fwlink/p/?LinkId=234834> requires the OEM ID and
OEM Table ID fields to be consistent between the SLIC and the RSDT/XSDT.
That further affects the FADT, because a similar match between the FADT
and the RSDT/XSDT is required by the ACPI spec in general.
This patch wires up the previous three patches.

qemu-system-x86_64 -trace bdrv_aio_writev -trace bdrv_aio_readv
or with globbing too:
qemu-system-x86_64 -trace 'bdrv_aio_*'
if an appropriate backend is enabled (simple, stderr, ftrace).
