Andreas Färber 1b71f7c14f qom: Register QOM infrastructure early
The constructors for QOM TYPE_INTERFACE were executed rather late in
vl.c's main(). Call them very early so that QOM can safely be used for
machines and CPUs.

Eduardo Habkost ecf40beae7 initialize CPU model list after handling -readconfig options
To properly load cpudefs using -readconfig, we have to call
cpudef_init() after finishing the command-line option handling.

Consequently, the handling of "-cpu ?" has to be done after the
command-line option handling loop, too.

Without this patch, "-readconfig configfile -cpu ?" fails to list the
CPU definitions read from 'configfile'.

Jan Kiszka 3741715cf2 usb: Resolve warnings about unassigned bus on usb device creation
When creating an USB device the old way, there is no way to specify the
target bus. Thus the warning issued by usb_create makes no sense and
rather confuses our users.

Resolve this by passing a bus reference to the usbdevice_init handler
and letting those handlers forward it to usb_create.

Gerd Hoffmann 95b363b5c6 suspend: add infrastructure
This patch adds some infrastructure to handle suspend and resume to
qemu.  First there are two functions to switch state and second there
is a suspend notifier:

 * qemu_system_suspend_request is supposed to be called when the
   guest asks for being be suspended, for example via ACPI.

 * qemu_system_wakeup_request is supposed to be called on events
   which should wake up the guest.

 * qemu_register_suspend_notifier can be used to register a notifier
   which will be called when the guest is suspended.  Machine types
   and device models can hook in there to modify state if needed.

 * qemu_register_wakeup_notifier can be used to register a notifier
   which will be called when the guest is woken up.  Machine types
   and device models can hook in there to modify state if needed.

 * qemu_system_wakeup_enable can be used to enable/disable wakeup
   events.

Ronnie Sahlberg f9dadc9855 iSCSI: add configuration variables for iSCSI
This patch adds configuration variables for iSCSI to set
initiator-name to use when logging in to the target,
which type of header-digest to negotiate with the target
and username and password for CHAP authentication.

This allows specifying a initiator-name either from the command line
-iscsi initiator-name=iqn.2004-01.com.example:test
or from a configuration file included with -readconfig
    [iscsi]
      initiator-name = iqn.2004-01.com.example:test
      header-digest = CRC32C|CRC32C-NONE|NONE-CRC32C|NONE
      user = CHAP username
      password = CHAP password

If you use several different targets, you can also configure this on a per
target basis by using a group name:
    [iscsi "iqn.target.name"]
    ...

The configuration file can be read using -readconfig.
Example :
qemu-system-i386 -drive file=iscsi://127.0.0.1/iqn.ronnie.test/1
 -readconfig iscsi.conf

Michael Roth d34e8f6e9d main-loop: For tools, initialize timers as part of qemu_init_main_loop()
In some cases initializing the alarm timers can lead to non-negligable
overhead from programs that link against qemu-tool.o. At least,
setting a max-resolution WinMM alarm timer via mm_start_timer() (the
current default for Windows) can increase the "tick rate" on Windows
OSs and affect frequency scaling, and in the case of tools that run
in guest OSs such has qemu-ga, the impact can be fairly dramatic
(+20%/20% user/sys time on a core 2 processor was observed from an idle
Windows XP guest).

This patch doesn't address the issue directly (not sure what a good
solution would be for Windows, or what other situations it might be
noticeable), but it at least limits the scope of the issue to programs
that "opt-in" to using the main-loop.c functions by only enabling alarm
timers when qemu_init_main_loop() is called, which is already required
to make use of those facilities, so existing users shouldn't be
affected.

SeaBIOS always expects to setup max_cpus number of SRAT cpu entries
(MaxCountCPUs variable in build_srat function of Seabios). When qemu-kvm runs
with smp_cpus != max_cpus (e.g. -smp 2,maxcpus=4), Seabios will mistakenly use
memory SRAT info for setting up CPU SRAT entries for the offline CPUs. Wrong
SRAT memory entries are also created. This breaks NUMA in a guest.

The caller of qemu_timedate_diff() does not expect that tm it passes to
the function will be modified, but mktime() is destructive and modifies
its argument. Pass a copy of tm to it and set tm_isdst so that mktime()
will not rely on it since its value may be outdated.

Andreas Färber db529aabfa vl.c: Guard against GThread double-initialization
GThread-ERROR **: GThread system may only be initialized once.
aborting...

Making the g_thread_init() call in vl.c conditional resolves an abort on
Mac OS X, where coroutine-gthread.c seems to call it before vl.c.

Aneesh Kumar K.V 9db221ae73 hw/9pfs: Add synthetic file system support using 9p
This patch create a synthetic file system with mount tag
v_synth when -virtfs_synth command line option is specified
in qemu. The synthetic file system can be mounted in guest
using 9p using the below command line

mount -t 9p -oversion=9p2000.L,trans=virtio v_synth  <mountpint>

Synthetic file system enabled different qemu subsystem to register
callbacks for read and write events from guest. The subsystem
can create directories and files in the synthetic file system as show
in ex below

    qemu_v9fs_synth_mkdir(NULL, 0777, "test2", &node);
    qemu_v9fs_synth_add_file(node, 0777, "testfile",
                             my_test_read, NULL, NULL);

is given to 9p export.

Luiz Capitulino f795e743bd Drop qemu-objects.h from modules that don't require it
Previous commits dropped most qobjects usage from qemu modules
(now they are a low level interface used by the QAPI). However,
some modules still include the qemu-objects.h header file.

This commit drops qemu-objects.h from some of those modules
and includes qjson.h instead, which is what they actually need.
