4171d32e6e Introduce -display none
New option -display none. This option differs from -nographic by not
trying to take control of stdio etc. but instead behaves as if a
graphics display is enabled, except that it doesn't show one.

5430a28fe4 vhost: force vhost off for non-MSI guests
When MSI is off, each interrupt needs to be bounced through the io
thread when it's set/cleared, so vhost-net causes more context switches and
higher CPU utilization than userspace virtio which handles networking in
the same thread.

We'll need to fix this by adding level irq support in kvm irqfd,
for now disable vhost-net in these configurations.

Added a vhostforce flag to force vhost-net back on.

cbcc6336ce spice: add chardev (v5)
Adding a chardev backend for spice, where spice determines what
to do with it based on the name attribute given during chardev creation.
For usage by spice vdagent in conjunction with a properly named
virtio-serial device, and future smartcard channel usage.

Example usage:
 qemu -device virtio-serial -chardev spicevmc,name=vdagent,id=vdagent \
 -device virtserialport,chardev=vdagent,name=com.redhat.spice.0

v4->v5:
 * add tracing events
 * fix missing comma
 * fix help string to show debug is optional

v3->v4:
 * updated commit message

v1->v3 changes: (v2 had a wrong commit message)
 * removed spice-qemu-char.h, folded into ui/qemu-spice.h
 * removed dead IOCTL code
 * removed comment
 * removed ifdef CONFIG_SPICE from qemu-config.c and qemu-options.hx help.

a19cbfb346 spice: add 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".

[ v2: add copyright to files                     ]

3a75e74c76 net/sock: option to specify local address
Add an option to specify the host IP to send multicast packets from,
when using a multicast socket for networking. The option takes an IP
address and sets the IP_MULTICAST_IF socket option, which causes the
packets to use that IP's interface as an egress.

This is useful if the host machine has several interfaces with several
virtual networks across disparate interfaces.

6c6b6ba20a move 'unsafe' to end of caching modes in help
Libvirt parses qemu help output to determine qemu features. In particular
it probes for the following: "cache=writethrough|writeback|none". The
addition of the unsafe cache mode was inserted within this string, as
opposed to being added to the end, which impacted libvirt's probe.
Unbreak libvirt by keeping the existing cache modes intact and add
unsafe to the end.

This problem only manifests itself if a caching mode is explicitly
specified in the libvirt xml, in which case older syntax for caching is
passed to qemu, which it  no longer understands.

016f5cf6ff Add cache=unsafe parameter to -drive
Usually the guest can tell the host to flush data to disk. In some cases we
don't want to flush though, but try to keep everything in cache.

So let's add a new cache value to -drive that allows us to set the cache
policy to most aggressive, disabling flushes. We call this mode "unsafe",
as guest data is not guaranteed to survive host crashes anymore.

This patch also adds a noop function for aio, so we can do nothing in AIO
fashion.

98b19252cf virtio-console: qdev conversion, new virtio-serial-bus
This commit converts the virtio-console device to create a new
virtio-serial bus that can host console and generic serial ports. The
file hosting this code is now called virtio-serial-bus.c.

The virtio console is now a very simple qdev device that sits on the
virtio-serial-bus and communicates between the bus and qemu's chardevs.

This commit also includes a few changes to the virtio backing code for
pci and s390 to spawn the virtio-serial bus.

As a result of the qdev conversion, we get rid of a lot of legacy code.
The old-style way of instantiating a virtio console using

    -virtioconsole ...

is maintained, but the new, preferred way is to use

    -device virtio-serial -device virtconsole,chardev=...

With this commit, multiple devices as well as multiple ports with a
single device can be supported.

For multiple ports support, each port gets an IO vq pair. Since the
guest needs to know in advance how many vqs a particular device will
need, we have to set this number as a property of the virtio-serial
device and also as a config option.

In addition, we also spawn a pair of control IO vqs. This is an internal
channel meant for guest-host communication for things like port
open/close, sending port properties over to the guest, etc.

This commit is a part of a series of other commits to get the full
implementation of multiport support. Future commits will add other
support as well as ride on the savevm version that we bump up here.

c9f398e53f debugcon: support for debugging consoles (e.g. Bochs port 0xe9)
Add generic support for debugging consoles (simple I/O ports which
when written to cause debugging output to be written to a target.)
The current implementation matches Bochs' port 0xe9, allowing the same
debugging code to be used for both Bochs and Qemu.

There is no vm state associated with the debugging port, simply
because it has none -- the entire interface is a single, stateless,
write-only port.

Most of the code was cribbed from the serial port driver.

v2: removed non-ISA variants (they can be introduced when/if someone
wants them, using code from the serial port); added configurable
readback (Bochs returns 0xe9 on a read from this register, mimic that
by default)  This retains the apparently somewhat controversial user
friendly option, however.

v3: reimplemented the user friendly option as a synthetic option
("-debugcon foo" basically ends up being a parser-level shorthand for
"-chardev stdio,id=debugcon -device isa-debugcon,chardev=debugcon") --
this dramatically reduced the complexity while keeping the same level
of user friendliness.

v4: spaces, not tabs.

v5: update to match current top of tree.  Calling qemu_chr_open()
already during parsing no longer works; defer until we are parsing the
other console-like devices.

d0fef6fbea qdev: add command line option to set global defaults for properties.
This patch adds infrastructure and command line option for setting
global defaults for device properties, i.e. you can for example use

  -global virtio-blk-pci.vectors=0

to turn off msi by default for all virtio block devices.  The config
file syntax is:

[global]
  driver = "virtio-blk-pci"
  property = "vectors"
  value = "0"

This can also be used to set properties for devices which are not
created via -device but implicitly via machine init, i.e.

  -global isa-fdc,driveA=<name>

This patch uses the mechanism which configures properties for the
compatibility machine types (pc-0.10 & friends).  The command line
takes precedence over the machine type values.

adcb181afe monitor: Command-line flag to enable control mode
This commit adds a flag called 'control' to the '-monitor'
command-line option. This flag enables control mode.

The syntax is:

qemu [...] -monitor control,<device>

Where <device> is a chardev (excluding 'vc', for obvious reasons).

For example:

$ qemu [...] -monitor control,tcp:localhost:4444,server

Will run QEMU in control mode, waiting for a client TCP connection
on localhost port 4444.

NOTE: I've tried using QemuOpts for this, but turns out that it
will try to parse the device part, which should be untouched.

715a664ac4 QemuOpts: command line switches for the config file.
Adds -readconfig and -writeconfig command line switches to read/write
QemuOpts from config file.

In theory you should be able to do:

  qemu < machine config cmd line switches here > -writeconfig vm.cfg
  qemu -readconfig vm.cfg

In practice it will not work.  Not all command line switches are
converted to QemuOpts, so you'll have to keep the not-yet converted ones
on the second line.  Also there might be bugs lurking which prevent even
the converted ones from working correctly.

default. This has the advantage that the emulated RTC will follow
automatically the host time while it might be tuned via NTP. vm_clock

Note that some RTC emulations (at least M48T59) already use the host

191bc01bc9 switch chardev to QemuOpts: infrastructure, null device
start switching chardevs to QemuOpts.  This patch adds the
infrastructure and converts the null device.

The patch brings two new functions:

qemu_chr_open_opts()
	same as qemu_chr_open(), but uses QemuOpts instead of a
	option char string.

qemu_chr_parse_compat()
	accepts a traditional chardev option string, returns the
	corresponding QemuOpts instance, to handle backward
	compatibility.

The patch also adds a new -chardev switch which can be used to create
named+unconnected chardevs, like this:

	-chardev null,id=test

This uses the new qemu_chr_open_opts.  Thus with this patch alone only
the null device works.  The other devices will follow ...

AIO support.  It's an extremly thing layer just setting up an iocb for

from there.

This started out based on Anthony's earlier AIO patch, but after

there's not much left of it.

To enable native kernel aio use the aio=native sub-command on the

4a1418e07b Unbreak large mem support by removing kqemu
kqemu introduces a number of restrictions on the i386 target.  The worst is that
it prevents large memory from working in the default build.

Furthermore, kqemu is fundamentally flawed in a number of ways.  It relies on
the TSC as a time source which will not be reliable on a multiple processor
system in userspace.  Since most modern processors are multicore, this severely
limits the utility of kqemu.

kvm is a viable alternative for people looking to accelerate qemu and has the
benefit of being supported by the upstream Linux kernel.  If someone can
implement work arounds to remove the restrictions introduced by kqemu, I'm
happy to avoid and/or revert this patch.

N.B. kqemu will still function in the 0.11 series but this patch removes it from
the 0.12 series.

fc5b81d1f6 net: set a default value for sndbuf=
On reflection, perhaps it does make sense to set a default value for
the sndbuf= tap parameter.

For best effect, sndbuf= should be set to just below the capacity of
the physical NIC.

Setting it higher will cause packets to be dropped before the limit
is hit. Setting it much lower will not cause any problems unless
you set it low enough such that the guest cannot queue up new packets
before the NIC has emptied its queue.

In Linux, txqueuelen=1000 by default for ethernet NICs. Given a 1500
byte MTU, 1Mb is a good choice for sndbuf.

If it turns out that txqueuelen is actually much lower than this, then
sndbuf is essentially disabled. In the event that txqueuelen is much
higher, it's unlikely that the NIC will be able to empty a 1Mb queue.

Thanks to Herbert Xu for this logic.

0df0ff6de7 net: add '-net tap,sndbuf=nbytes'
2.6.30 adds a new TUNSETSNDBUF ioctl() which allows a send buffer limit
for the tap device to be specified. When this limit is reached, a tap
write() will return EAGAIN and poll() will indicate the fd isn't
writable.

This allows people to tune their setups so as to avoid e.g. UDP packet
loss when the sending application in the guest out-runs the NIC in the
host.

There is no obviously sensible default setting - a suitable value
depends mostly on the capabilities of the physical NIC through which the
packets are being sent.

Also, note that when using a bridge with netfilter enabled, we currently
never get EAGAIN because netfilter causes the packet to be immediately
orphaned. Set /proc/sys/net/bridge/bridge nf-call-iptables to zero to
disable this behaviour.

d4ebe1934a slirp: Enhance host-guest redirection setup (Jan Kiszka)
Allow to establish a TCP/UDP connection redirection also via a monitor
command 'host_net_redir'. Moreover, assume TCP as connection type if
that parameter is omitted.

bb9ea79e7a net: Add support for capturing VLANs (Jan Kiszka)
This patch is derived from Tristan Gingold's patch. It adds a new VLAN
client type that writes all traffic on the VLAN it is attached to into a
pcap file. Such a file can then be analyzed offline with Wireshark or
tcpdump.

Besides rebasing and some minor cleanups, the major differences to the
original version are:
 - support for enabling/disabling via the monitor (host_net_add/remove)
 - no special ordering of VLAN client list, qemu_send_packet now takes
   care of properly ordered packets
 - 64k default capturing limit (I hate tcpdump's default)

b6f6e3d3a7 qemu: Add support for SMBIOS command line otions (Alex Williamson)
Create a new -smbios option (x86-only) to allow binary SMBIOS entries
to be passed through to the BIOS or modify the default values of
individual fields of type 0 and 1 entries on the command line.

Binary SMBIOS entries can be generated as follows:

dmidecode -t 1 -u | grep $'^\t\t[^"]' | xargs -n1 | \
        perl -lne 'printf "%c", hex($_)' > smbios_type_1.bin

These can then be passed to the BIOS using this switch:

 -smbios file=smbios_type_1.bin

Command line generation supports the following syntax:

 -smbios type=0[,vendor=str][,version=str][,date=str][,release=%d.%d]
 -smbios type=1[,manufacturer=str][,product=str][,version=str][,serial=str]
              [,uuid=$(uuidgen)][,sku=str][,family=str]

For instance, to add a serial number to the type 1 table:

 -smbios type=1,serial=0123456789

Interface is extensible to support more fields/tables as needed.

59030a8cd4 gdbstub: Rework configuration via command line and monitor (Jan Kiszka)
Introduce a more canonical gdbstub configuration (system emulation only)
via the new switch '-gdb dev'. Keep '-s' as shorthand for
'-gdb tcp::1234'. Use the same syntax also for the corresponding monitor
command 'gdbserver'. Its default remains to listen on TCP port 1234.

Changes in v4:
 - Rebased over new command line switches meta file

Changes in v3:
 - Fix documentation

Changes in v2:
 - Support for pipe-based like to gdb (target remote | qemu -gdb stdio)
 - Properly update the qemu-doc

5824d65122 Syncing documentation vs. -help vs. qemu_options table
Try to keep documentation about command line switches, -help text and
qemu_options table synchronized. 

In true Qemu tradition, an include file is generated from single .hx file
containing all relevant information in one place. The include file is
parsed once for getting the enums, another time for getopt tables and
hird time for help messages. Texi documentation for the options is
generated from the same .hx file.
