Add -mon switch which maps pretty straight forward into the QemuOpts
internal representation:

  -mon chardev=<name>[,mode=[control|readline]][,[no]default]

Via config file:

[mon]

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.

6875204c78 Enable host-clock-based RTC
Switch RTC emulations to the new host_clock instead of vm_clock by
default. This has the advantage that the emulated RTC will follow
automatically the host time while it might be tuned via NTP. vm_clock
can still be selected by passing '-rtc clock=vm' on the command line.

Note that some RTC emulations (at least M48T59) already use the host
time unconditionally while others (namely MC146818) do not. This patch
introduces the required infrastructure for selecting the base clock but
only converts MC146818 for now.

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 ...

5c6c3a6c54 raw-posix: add Linux native AIO support
Now that do have a nicer interface to work against we can add Linux native
AIO support.  It's an extremly thing layer just setting up an iocb for
the io_submit system call in the submission path, and registering an
eventfd with the qemu poll handler to do complete the iocbs directly
from there.

This started out based on Anthony's earlier AIO patch, but after
estimated 42,000 rewrites and just as many build system changes
there's not much left of it.

To enable native kernel aio use the aio=native sub-command on the
drive command line.  I have also added an option to qemu-io to
test the aio support without needing a guest.

0d6b0b1d81 Make the e1000 the default network adapter for the pc target.
The ne2k is an ancient card that performs pretty terribly under QEMU.  In many
modern OSes, there is no longer drivers available for the ne2k.

Switch the default network adapter to e1000.  This card is more widely
suppported and performs rather well under QEMU.  There may be very old OSes
that had a ne2k driver but not an e1000 driver but I think this is likely the
exception.

I think the average user is better served with an e1000 vs ne2k.

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.

Paul, please Ack or Nack this patch.

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.
