Add following parameters:
  "slots" - total number of hotplug memory slots
  "maxmem" - maximum possible memory

"slots" and "maxmem" should go in pair and "maxmem" should be greater
than "mem" for memory hotplug to be enabled.

5b808275f3 trace: Multi-backend tracing
Adds support to compile QEMU with multiple tracing backends at the same time.

For example, you can compile QEMU with:

  $ ./configure --enable-trace-backends=ftrace,dtrace

Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system.

This patch allows having both available without recompiling QEMU.

9f9260a3be qdev: Display warning about unused -global
This can help a user understand why -global was ignored.

For example: with "-vga cirrus"; "-global vga.vgamem_mb=16" is just
ignored when "-global cirrus-vga.vgamem_mb=16" is not.

This is currently clear when the wrong property is provided:

out/x86_64-softmmu/qemu-system-x86_64 -global cirrus-vga.vram_size_mb=16 -monitor pty -vga cirrus
char device redirected to /dev/pts/20 (label compat_monitor0)

The 'name' option silently failed when used in config files
( http://lists.gnu.org/archive/html/qemu-devel/2014-04/msg00378.html )

-readconfig stores the configuration read in QemuOpts.  Command line
option parsing should do the same, and no more.  In particular it should
not act upon the option.  That needs to be done separately, where both
command line and -readconfig settings are visible in QemuOpts.

02ce232c50 vl.c: remove init_clocks call from main
Clocks are initialized in qemu_init_main_loop. They are not needed before it.
Initializing them twice is not only unnecessary but is harmful: it results in
memory leak and potentially can lead to a situation where different parts of
QEMU use different sets of timers.

To avoid it remove init_clocks call from main and add an assertion to
qemu_clock_init that corresponding clock has not been initialized yet.

ae2990c259 osdep: initialize glib threads in all QEMU tools
glib versions prior to 2.31.0 require an explicit g_thread_init() call
to enable multi-threading.

Failure to initialize threading causes glib to take single-threaded code
paths without synchronization.  For example, the g_slice allocator will
crash due to race conditions.

Fix this for all QEMU tool programs (qemu-nbd, qemu-io, qemu-img) by
moving the g_thread_init() call from vl.c:main() into a new
osdep.c:thread_init() constructor function.

thread_init() has __attribute__((constructor)) and is automatically
invoked by the runtime during startup.

We can now drop the "simple" trace backend's g_thread_init() call since
thread_init() already called it.

Note that we must keep coroutine-gthread.c's g_thread_init() call which
is located in a constructor function.  There is no guarantee for
constructor function ordering so thread_init() may only be called later.

30e32af746 vl.c: Extend get_boot_devices_list() to ignore suffixes
As suffixes do not make sense for sPAPR's device tree and
there is no way to filter them out on the BusState::get_fw_dev_path()
level, let's add an ability for the external caller to specify
whether to apply suffixes or not.

We could handle suffixes in SLOF (ignored for now) but this would require
serious rework in the node opening code in SLOF, which has no obvious
benefit for the currently emulated sPAPR machine.

==54082==    by 0x80013B91: main (vl.c:3000)

Turns out that valgrind is right. We simply forget the memory that
g_strconcat() has allocated. Lets free it after the type_register().
We need a 2nd variable due to constness of the name part of the
type structure.

7effdaa321 spapr: Fix return value of vga initialization
Before spapr_vga_init will returned false if the vga is specified by
the command '-device VGA' because vga_interface_type was evaluated to
VGA_NONE. With the change in previous patch of this series,
spapr_vga_init should return true if it's told that the vga will be
initialized in flow of the generic devices initialization.

To keep '-nodefaults' have the semantics of bare minimum, it adds a
check of 'has_defaults' in usb_enabled() to avoid that a USB controller
is added by '-nodefautls, -device VGA' implicitly.

This patch also makes two cleanups:
1. skip initialization for VGA_NONE
2. remove the useless 'break'

d44229c54f Fix vga_interface_type for command line argument '-device VGA'
Some machine (like pseries) initialization code determines if it has
graphics according to vga_interface_type. In the original code,
vga_interface_type is evaluated to VGA_NONE even if a VGA is added
via '-device VGA'. It causes the machine not aware of the graphics
device configured. Add a new VGA device type to indicate that it has a
VGA device, which will be initialized in QOM device initialization.

af87bf290f sun4m: Add Sun CG3 framebuffer initialisation function
In order to allow the user to choose the framebuffer for sparc-softmmu, add
-vga tcx and -vga cg3 options to the QEMU command line. If no option is
specified, the default TCX framebuffer is used.

Since proprietary FCode ROMs use a resolution of 1152x900, slightly relax the
validation rules to allow both displays to be initiated at the higher
resolution used by these ROMs upon request (OpenBIOS FCode ROMs default to
the normal QEMU sun4m default resolution of 1024x768).

Finally move any fprintf(stderr ...) statements in the areas affected by this
patch over to the new error_report() function.

84d18f065f Use error_is_set() only when necessary
error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out.  Unnecessarily hard for
optimizers, static checkers, and human readers.  Dumb it down to
obvious.

Gets rid of several dozen Coverity false positives.

Note that the obvious form is already used in many places.

b33276a7a8 vl: trim includes
Over time, lots of stuff moved from vl.c into separate
files.  But include statements has never been cleaned,
and they continue to carry lots of anymore-unused stuff.

Remove includes which are not relevant for vl.c anymore.
Apparently there are more includes like this, because
many are included from qemu-common.h and the like, or,
for example, I don't see were we use win32-specific
stuff in vl.c (so that maybe #include <windows.h> might
be removed too).

f31c41ff5e block: Handle "rechs" and "large" translation options
Sure, CHS translation is an obscure topic, and legacy options for
hard-disk geometries are obscure as well.  But since QEMU does nothing
with it except telling the BIOS, and since there "large" and "rechs"
are listed in the enums, parsing them seems to be the bare minimum.

269e09f3fc add optional 2nd stage initialization to -object/object-add commands
Introduces USER_CREATABLE interface that must be implemented by
objects which are designed to created with -object CLI option or
object-add QMP command.

Interface provides an ability to do an optional second stage
initialization of the object created with -object/object-add
commands. By providing complete() callback, which is called
after the object properties were set.

It allows to:
 * prevents misusing of -object/object-add by filtering out
   objects that are not designed for it.
 * generalize second stage backend initialization instead of
   adding custom APIs to perform it
 * early error detection of backend initialization at -object/
   object-add time rather than through a proxy DEVICE object
   that tries to use backend.

When running with trace backend e.g. "simple" the writer thread needs to be
implemented in the same process context as the trace points that will be
processed. Under libvirtd control, qemu gets first started in daemonized
mode to privide its capabilities. Creating the writer thread in the initial
process context then leads to a dead lock because the thread gets termined
together with the initial parent. (-daemonize)

f46e720a82 qemu_opts_parse(): always check return value
qemu_opts_parse() can always return NULL, even if the QemuOptsList.desc in
question would be trivial to satisfy (eg. because it's empty). For
example:

qemu_opts_parse()
  opts_parse()
    qemu_opts_create()
      id_wellformed()

In practice:

  $ .../qemu-system-x86_64 -acpitable id=3
  qemu-system-x86_64: -acpitable id=3: Parameter 'id' expects an identifier
  **
  ERROR:vl.c:3491:main: assertion failed: (opts != NULL)
  Aborted (core dumped)

  $ .../qemu-system-x86_64 -smbios id=3
  qemu-system-x86_64: -smbios id=3: Parameter 'id' expects an identifier
  Segmentation fault (core dumped)

I checked all qemu_opts_parse() invocations (and all drive_def()
invocations too, because it blindly forwards the former's retval). Only
the two above examples look problematic.

d4fce24f3a qtest: split configuration of qtest accelerator and chardev
qtest uses the icount infrastructure to implement a test-driven vm_clock.  This
however is not necessary when using -qtest as a "probe" together with a normal
TCG-, KVM- or Xen-based virtual machine.  Hence, split out the call to
configure_icount into a new function that is called only for "-machine
accel=qtest"; and disable those commands when running with an accelerator
other than qtest.

This also fixes an assertion failure with "qemu-system-x86_64 -machine
accel=qtest" but no -qtest option.  This is a valid case, albeit somewhat
weird; nothing will happen in the VM but you'll still be able to
interact with the monitor or the GUI.

Now that qtest_init is not limited to an int(void) function, change
global variables that are not used outside qtest_init to arguments.

And finally, cleanup useless parts of include/sysemu/qtest.h.  The file
is not used at all for user-only emulation, and qtest is not available
on Win32 due to its usage of sigwait.

df39076850 vl: allow "cont" from panicked state
After reporting the GUEST_PANICKED monitor event, QEMU stops the VM.
The reason for this is that events are edge-triggered, and can be lost if
management dies at the wrong time.  Stopping a panicked VM lets management
know of a panic even if it has crashed; management can learn about the
panic when it restarts and queries running QEMU processes.  The downside
is of course that the VM will be paused while management is not running,
but that is acceptable if it only happens with explicit "-device pvpanic".

Upon learning of a panic, management (if configured to do so) can pick a
variety of behaviors: leave the VM paused, reset it, destroy it.  In
addition to all of these behaviors, it is possible to dump the VM core
from the host.

However, right now, the panicked state is irreversible, and can only be
exited by resetting the machine.  This means that any policy decision
is entirely in the hands of the host.  In particular there is no way to
use the "reboot on panic" option together with pvpanic.

This patch makes the panicked state reversible (and removes various
workarounds that were there because of the state being irreversible).
With this change, management has a wider set of possible policies: it
can just log the crash and leave policy to the guest, it can leave the
VM paused.  In particular, the "log the crash and continue" is implemented
simply by sending a "cont" as soon as management learns about the panic.
Management could also implement the "irreversible paused state" itself.
And again, all such actions can be coupled with dumping the VM core.

Unfortunately we cannot change the behavior of 1.6.0.  Thus, even if
it uses "-device pvpanic", management should check for "cont" failures.
If "cont" fails, management can then log that the VM remained paused
and urge the administrator to update QEMU.

9fa032866d spice: fix multihead support
This patch fixes spice display initialization to handle
multihead properly.

spice-core now keeps track of which QemuConsole has a spice
display channel attached to it and which has not.  It also
manages display channel ids.

spice-display looks at all QemuConsoles and will pick up any
graphic console not yet bound to a spice channel (which in practice
are all non-qxl graphic devices).

Result is that
 (a) you'll get a spice client window for each graphical device
     now (first only without this patch), and
 (b) mixing qxl and non-qxl vga cards works properly.

fc3b32958a smbios: Make multiple -smbios type= accumulate sanely
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with
value VAL to fw_cfg for each unique NAME.  If NAME occurs multiple
times, the last one's VAL is used (before the QemuOpts conversion, the
first one was used).

Multiple -smbios can add multiple fields with the same (T, NAME).
SeaBIOS reads all of them from fw_cfg, but uses only the first field
(T, NAME).  The others are ignored.

"First one wins, subsequent ones get ignored silently" isn't nice.  We
commonly let the last option win.  Useful, because it lets you
-readconfig first, then selectively override with command line
options.

Clean up -smbios to work the common way.  Accumulate the settings,
with later ones overwriting earlier ones.  Put the result into fw_cfg
(no more useless duplicates).

Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by
side effect.

4bc78a8772 qemu: Adjust qemu wakeup
Currently Xen hvm s3 has a bug coming from the difference between
qemu-traditioanl and qemu-xen. For qemu-traditional, the way to
resume from hvm s3 is via 'xl trigger' command. However, for
qemu-xen, the way to resume from hvm s3 inherited from standard
qemu, i.e. via QMP, and it doesn't work under Xen.

The root cause is, for qemu-xen, 'xl trigger' command didn't reset
devices, while QMP didn't unpause hvm domain though they did qemu
system reset.

We have two qemu patches and one xl patch to fix Xen hvm s3 bug.
This patch is the qemu patch 1. It adjusts qemu wakeup so that
Xen s3 resume logic (which will be implemented at qemu patch 2)
will be notified after qemu system reset.

c165473269 hw: Clean up bogus default boot order
We set default boot order "cad" in every single machine definition
except "pseries" and "moxiesim", even though very few boards actually
care for boot order, and "cad" makes sense for even fewer.

Machines that care:

* pc and its variants

  Accept up to three letters 'a', 'b' (undocumented alias for 'a'),
  'c', 'd' and 'n'.  Reject all others (fatal with -boot).

* nseries (n800, n810)

  Check whether order starts with 'n'.  Silently ignored otherwise.

* prep, g3beige, mac99

  Extract the first character the machine understands (subset of
  'a'..'f').  Silently ignored otherwise.

* spapr

  Accept an arbitrary string (vl.c restricts it to contain only
  'a'..'p', no duplicates).

* sun4[mdc]

  Use the first character.  Silently ignored otherwise.

Strip characters these machines ignore from their default boot order.

For all other machines, remove the unused default boot order
alltogether.

Note that my rename of QEMUMachine member boot_order to
default_boot_order and QEMUMachineInitArgs member boot_device to
boot_order has a welcome side effect: it makes every use of boot
orders visible in this patch, for easy review.

Per Markus's comment below, A conversion from fprintf() to

But, it is not reasonable to convert them at one time
because fprintf() is used everwhere in qemu.

Spice has two display interface implementations:  One integrated into

The generic one is activated in case spice is used without qxl.  The
logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes
unnoticed.  Fix that by adding a check in the spice interface
registration so we'll notice the qxl card no matter how it is created.

[Issue]
When we offer a customer support service and a problem happens
in a customer's system, we try to understand the problem by
comparing what the customer reports with message logs of the
customer's system.

In this case, we often need to know when the problem happens.

But, currently, there is no timestamp in qemu's error messages.
Therefore, we may not be able to understand the problem based on
error messages.

[Solution]
Add a timestamp to qemu's error message logged by
error_report() with g_time_val_to_iso8601().

36ad0e948e Fix -machine options accel, kernel_irqchip, kvm_shadow_mem
Multiple -machine options with the same ID are merged.  All but the
one without an ID are to be silently ignored.

In most places, we query these options with a null ID.  This is
correct.

In some places, we instead query whatever options come first in the
list.  This is wrong.  When the -machine processed first happens to
have an ID, options are taken from that ID, and the ones specified
without ID are silently ignored.

Example:

    $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on
    $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen

Option usb is queried correctly, and the one without an ID wins,
regardless of option order.

Option accel is queried incorrectly, and which one wins depends on
option order and ID.

Affected options are accel (and its sugared forms -enable-kvm and
-no-kvm), kernel_irqchip, kvm_shadow_mem.

Additionally, option kernel_irqchip is normally on by default, except
it's off when no -machine options are given.  Bug can't bite, because
kernel_irqchip is used only when KVM is enabled, KVM is off by
default, and enabling always creates -machine options.  Downstreams
that enable KVM by default do get bitten, though.

Use qemu_get_machine_opts() to fix these bugs.

12b7f57e2c vl: convert -smp to qemu_opts_parse()
This also introduces a new suboption, "cpus=",
which is the default.  So after this patch,

 -smp n,sockets=y

is the same as

  -smp cpus=n,sockets=y

(with "cpu" being some generic thing, referring to
either cores, or threads, or sockets, as before).

We still don't validate relations between different
numbers, for example it is still possible to say

  -smp 1,sockets=10

and it will be accepted to mean sockets=1.

8281abd548 vl: Fix -boot order and once regressions, and related bugs
Option "once" sets up a different boot order just for the initial
boot.  Boot order reverts back to normal on reset.  Option "order"
changes the normal boot order.

The reversal is implemented by reset handler restore_boot_devices(),
which takes the boot order to revert to as argument.
restore_boot_devices() does nothing on its first call, because that
must be the initial machine reset.  On its second call, it changes the
boot order back, and unregisters itself.

Because we register the handler right when -boot gets parsed, we can
revert to an incorrect normal boot order, and multiple -boot can
interact in funny ways.

Here's how things work without -boot once or order:

* boot_devices is "".

* main() passes machine->boot_order to to machine->init(), because
  boot_devices is "".  machine->init() configures firmware
  accordingly.  For PC machines, machine->boot_order is "cad", and
  pc_cmos_init() writes it to RTC CMOS, where SeaBIOS picks it up.

Now consider -boot order=:

* boot_devices is "".

* -boot order= sets boot_devices to "" (no change).

* main() passes machine->boot_order to to machine->init(), because
  boot_devices is "", as above.

  Bug: -boot order= has no effect.  Broken in commit e4ada29e.

Next, consider -boot once=a:

* boot_devices is "".

* -boot once=a registers restore_boot_devices() with argument "", and
  sets boot_devices to "a".

* main() passes boot_devices "a" to machine->init(), which configures
  firmware accordingly.  For PC machines, pc_cmos_init() writes the
  boot order to RTC CMOS.

* main() calls qemu_system_reset().  This runs reset handlers.

  - restore_boot_devices() gets called with argument "".  Does
    nothing, because it's the first call.

* Machine boots, boot order is "a".

* Machine resets (e.g. monitor command).  Reset handlers run.

  - restore_boot_devices() gets called with argument "".  Calls
    qemu_boot_set("") to reconfigure firmware.  For PC machines,
    pc_boot_set() writes it into RTC CMOS.  Reset handler
    unregistered.

    Bug: boot order reverts to "" instead of machine->boot_order.  The
    actual boot order depends on how firmware interprets "".  Broken
    in commit e4ada29e.

Next, consider -boot once=a -boot order=c:

* boot_devices is "".

* -boot once=a registers restore_boot_devices() with argument "", and
  sets boot_devices to "a".

* -boot order=c sets boot_devices to "c".

* main() passes boot_devices "c" to machine->init(), which configures
  firmware accordingly.  For PC machines, pc_cmos_init() writes the
  boot order to RTC CMOS.

* main() calls qemu_system_reset().  This runs reset handlers.

  - restore_boot_devices() gets called with argument "".  Does
    nothing, because it's the first call.

* Machine boots, boot order is "c".

  Bug: it should be "a".  I figure this has always been broken.

* Machine resets (e.g. monitor command).  Reset handlers run.

  - restore_boot_devices() gets called with argument "".  Calls
    qemu_boot_set("") to reconfigure firmware.  For PC machines,
    pc_boot_set() writes it into RTC CMOS.  Reset handler
    unregistered.

    Bug: boot order reverts to "" instead of "c".  I figure this has
    always been broken, just differently broken before commit
    e4ada29e.

Next, consider -boot once=a -boot once=b -boot once=c:

* boot_devices is "".

* -boot once=a registers restore_boot_devices() with argument "", and
  sets boot_devices to "a".

* -boot once=b registers restore_boot_devices() with argument "a", and
  sets boot_devices to "b".

* -boot once=c registers restore_boot_devices() with argument "b", and
  sets boot_devices to "c".

* main() passes boot_devices "c" to machine->init(), which configures
  firmware accordingly.  For PC machines, pc_cmos_init() writes the
  boot order to RTC CMOS.

* main() calls qemu_system_reset().  This runs reset handlers.

  - restore_boot_devices() gets called with argument "".  Does
    nothing, because it's the first call.

  - restore_boot_devices() gets called with argument "a".  Calls
    qemu_boot_set("a") to reconfigure firmware.  For PC machines,
    pc_boot_set() writes it into RTC CMOS.  Reset handler
    unregistered.

  - restore_boot_devices() gets called with argument "b".  Calls
    qemu_boot_set("b") to reconfigure firmware.  For PC machines,
    pc_boot_set() writes it into RTC CMOS.  Reset handler
    unregistered.

* Machine boots, boot order is "b".

  Bug: should really be "c", because that came last, and for all other
  -boot options, the last one wins.  I figure this was broken some
  time before commit 37905d6a, and fixed there only for a single
  occurence of "once".

* Machine resets (e.g. monitor command).  Reset handlers run.

  - restore_boot_devices() gets called with argument "".  Calls
    qemu_boot_set("") to reconfigure firmware.  For PC machines,
    pc_boot_set() writes it into RTC CMOS.  Reset handler
    unregistered.

    Same bug as above: boot order reverts to "" instead of
    machine->boot_order.

Fix by acting upon -boot options order, once and menu only after
option parsing is complete, and the machine is known.  This is how the
other -boot options work already.

6ef4716cec vl: Clean up parsing of -boot option argument
Commit 3d3b8303 threw in some QemuOpts parsing without replacing the
existing ad hoc parser, resulting in a confusing mess.  Clean it up.

Two user-visible changes:

1. Invalid options are reported more nicely.  Before:

        qemu: unknown boot parameter 'x' in 'x=y'

   After:

        qemu-system-x86_64: -boot x=y: Invalid parameter 'x'

2. If -boot is given multiple times, options accumulate, just like for
   -machine.  Before, only options order, once and menu accumulated.
   For the other ones, all but the first -boot in non-legacy syntax
   got simply ignored.

a1077090ce vl: always define no_frame
Commit 047d4e151d "Unbreak -no-quit for GTK, validate SDL options" broke
build of qemu without sdl, by referencing `no_frame' variable which is defined
inside #if SDL block.  Fix that by defining that variable unconditionally.

This is a better fix for the build issue introduced by that patch than
a revert.  This change keeps the new functinality introduced by that patch
and just fixes the compilation.  It still is not a complete fix around the
original issue (not working -no-frame et al with -display gtk), because it
makes only the legacy interface working, not the new suboption interface,
so a few more changes are needed.

047d4e151d Unbreak -no-quit for GTK, validate SDL options
Certain options (-no-frame, -alt-grab, -ctrl-grab) only make sense with SDL.
When compiling without SDL, these options (and -no-quit) print an error message
and exit qemu.

In case QEMU is compiled with SDL support, the three aforementioned options
still do not make sense with other display types. This patch addresses that
issue by printing a warning. I have chosen not to exit QEMU afterwards because
having the option is not harmful and before this patch it would be ignored
anyway.

By delaying the sanity check from compile-time with some ifdefs to run-time,
-no-quit is now also properly supported when compiling without SDL.

bdee56f546 tpm: reorganize headers and split hardware part
The TPM subsystem does not have a full front-end/back-end separation.
The sole available backend, tpm_passthrough, depends on the data
structures of the sole available frontend, tpm_tis.

However, we can at least try to split the user interface (tpm.c) from the
implementation (hw/tpm).  The patches makes tpm.c not include tpm_int.h,
which is shared between tpm_tis.c and tpm_passthrough.c; instead it
moves more stuff to tpm_backend.h.

chardev-frontends need to explictly check, increase and decrement the
avail_connections "property" of the chardev when they are not using a
qdev-chardev-property for the chardev.

This fixes things like:
qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \
  -mon chardev=foo

Working, where they should fail. Most of the changes here are due to
old hardware emulation code which is using serial_hds directly rather then
a qdev-chardev-property.

c8a6ae8bb9 add a boot option to do strict boot
Seabios already added a new device type to halt booting.
Qemu can add "HALT" at the end of bootindex string, then
seabios will halt booting after trying to boot from all
selected devices.

This patch added a new boot option to configure if boot
from un-selected devices.

This option only effects when boot priority is changed by
bootindex options, the old style(-boot order=..) will still
try to boot from un-selected devices.

4524051c32 Add search path support for qemu data files.
This patch allows to specify multiple directories where qemu should look
for data files.  To implement that the behavior of the -L switch is
slightly different now:  Instead of replacing the data directory the
path specified will be appended to the data directory list.  So when
specifiying -L multiple times all directories specified will be checked,
in the order they are specified on the command line, instead of just the
last one.

Additionally the default paths are always appended to the directory
data list.  This allows to specify a incomplete directory (such as the
seabios out/ directory) via -L.  Anything not found there will be loaded
from the default paths, so you don't have to create a symlink farm for
all the rom blobs.

For trouble-shooting a tracepoint has been added, logging which blob
has been loaded from which location.

92dcc234ec Add support for cancelling of a TPM command
This patch adds support for cancelling an executing TPM command.
In Linux for example a user can cancel a command through the TPM's
sysfs 'cancel' entry using

echo "1" > /sysfs/class/misc/tpm0/device/cancel

This patch propagates the cancellation of a command inside a VM
to the host TPM's sysfs entry.
It also uses the possibility to cancel the command before QEMU VM
shutdown or reboot, which helps in preventing QEMU from hanging while
waiting for the completion of the command.
To relieve higher layers or users from having to determine the TPM's
cancel sysfs entry, the driver searches for the entry in well known
locations.

d1a0cf738d Support for TPM command line options
This patch adds support for TPM command line options.
The command line options supported here are

./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id>
           -device tpm-tis,tpmdev=<id>,id=<other id>

and

./qemu-... -tpmdev help

where the latter works similar to -soundhw help and shows a list of
available TPM backends (for example 'passthrough').

Using the type parameter, the backend is chosen, i.e., 'passthrough' for the
passthrough driver. The interpretation of the other parameters along
with determining whether enough parameters were provided is pushed into
the backend driver, which needs to implement the interface function
'create' and return a TPMDriverOpts structure if the VM can be started or
'NULL' if not enough or bad parameters were provided.

Monitor support for 'info tpm' has been added. It for example prints the
following:

(qemu) info tpm
TPM devices:
 tpm0: model=tpm-tis
  \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel

b09995aef1 qdev: drop extra references at creation time
qdev_free and qbus_free have to do unparent+unref, because nobody else
drops the initial reference (the one included by object_initialize)
before them.

For device_init_func and do_device_add, this is trivially correct,
since the DeviceState goes out of scope.

For qdev_create, qdev_try_create and qbus_init, it is a bit more tricky.
What we are doing here is just assuming that the caller knows what it's
doing, and won't call qdev_free/qbus_free while the device is still there.
This is a pretty reasonable assumption and (behind the scenes) is also
what GObject/GTK does.  GTK actually has a "floating reference" that
goes away as soon as the caller does gtk_container_add or something
like that, but in the end qbus_init and qdev_try_create are already
adding the new object to its qdev parent!  So in the end the two solutions
are the same.

Happens to work on my x86_64 box (64 bit little endian): the least

e4ada29e90 Make default boot order machine specific
This patch makes default boot order machine specific instead of
set globally. The default boot order can be set per machine in
QEMUMachine boot_order. This also allows a machine to receive a
NULL boot order when -boot isn't used and take an appropriate action
accordingly. This helps machine boots from the devices as set in
guest's non-volatile memory location in case no boot order is
provided by the user.

ab51b1d568 disallow -daemonize usage of stdio (curses display, -nographic, -serial stdio etc)
Curses display requires stdin/out to stay on the terminal,
so -daemonize makes no sense in this case.  Instead of
leaving display uninitialized like is done since 995ee2bf46,
explicitly detect this case earlier and error out.

-nographic can actually be used with -daemonize, by redirecting
everything to a null device, but the problem is that according
to documentation and historical behavour, -nographic redirects
guest ports to stdin/out, which, again, makes no sense in case
of -daemonize.  Since -nographic is a legacy option, don't bother
fixing this case (to allow -nographic and -daemonize by redirecting
guest ports to null instead of stdin/out in this case), but disallow
it completely instead, to stop garbling host terminal.

If no display display needed and user wants to use -nographic,
the right way to go is to use
  -serial null -parallel null -monitor none -display none -vga none
instead of -nographic.

Also prevent the same issue -- it was possible to get garbled
host tty after

  -nographic -daemonize

and it is still possible to have it by using

  -serial stdio -daemonize

Fix this by disallowing opening stdio chardev when -daemonize
is specified.

2d0d2837dc Support default block interfaces per QEMUMachine
There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a
default/standard interface to their block devices / drives. Therefore,
this patch introduces a new field default_block_type per QEMUMachine
struct. The prior use_scsi field becomes thereby obsolete and is
replaced through .default_block_type = IF_SCSI.

This patch also changes the default for s390x to IF_VIRTIO and
removes an early hack that converts IF_IDE drives.
Other parties have already claimed interest (e.g. IF_SD for exynos)

To create a sane default, for machines that dont specify a
default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1.
I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c)
as well as IF_IDE and it seems that it is ok to change the defines -
in other words, I found no obvious (to me) assumption in the code
regarding IF_NONE==0. IF_NONE is only set if there is an
explicit if=none. Without if=* the interface becomes IF_DEFAULT.

I would suggest to have some additional care, e.g. by letting
this patch sit some days in the block tree.

fa5358c69d vl.c: Fix broken -usb option
Commit 094b287f0b accidentally broke the "-usb" command line
option, so it would have no effect if the user had not specified
any machine options at that point. (the return value from
'qemu_opts_find(qemu_find_opts("machine"), 0);' is NULL if there
are no user specified options, so it is only to be used for
looking up an option, not when trying to set one.) Similarly,
would '-usbdevice' no longer cause USB to default to enabled.

Fix this regression by using the same style of code for forcing
the usb=on machine option that we use for other aliases such as
'-enable-kvm'.

49cf57281b vl: delay thread initialization after daemonization
Commit ac4119c (chardev: Use timer instead of bottom-half to postpone
open event, 2012-10-12) moved the alarm timer initialization to an earlier
point but failed to consider that it depends on qemu_init_main_loop.

Later, commit 1c53786 (vl: init main loop earlier, 2012-10-30) fixed
this, but left -daemonize in two different ways.  First, timers need to
be reinitialized after forking.  Second, the global mutex was being held
by the parent, and thus dropped after forking.

The first is now fixed using pthread_atfork.  For the second part,
make sure that the global mutex is not taken before daemonization,
and similarly delay qemu_thread_self.

ac4119c023 chardev: Use timer instead of bottom-half to postpone open event
As the block layer may decide to flush bottom-halfs while the machine is
still initializing (e.g. to read geometry data from the disk), our
postponed open event may be processed before the last frontend
registered with a muxed chardev.

Until the semantics of BHs have been clarified, use an expired timer to
achieve the same effect (suggested by Paolo Bonzini). This requires to
perform the alarm timer initialization earlier as otherwise timer
subsystem can be used before being ready.

094b287f0b Add USB option in machine options
When -usb option is used, global varible usb_enabled is set.
And all the plaform will create one USB controller according
to this variable. In fact, global varibles make code hard
to read.

So this patch is to remove global variable usb_enabled and
add USB option in machine options. All the plaforms will get
USB option value from machine options.

USB option of machine options will be set either by:
  * -usb
  * -machine type=pseries,usb=on

Both these ways can work now. They both set USB option in
machine options. In the future, the first way will be removed.

29ed72f15a migration: go to paused state after finishing incoming migration with -S
At the end of migration the machine has started already, and cannot be
destroyed without losing the guest's data.  Hence, prelaunch is the
wrong state.  Go to the paused state instead.  QEMU would reach that
state anyway (after running the guest for the blink of an eye) if the
"stop" command had been received after the start of migration.

587ed6be0b qemu-config: Add new -add-fd command line option
This option can be used for passing file descriptors on the
command line.  It mirrors the existing add-fd QMP command which
allows an fd to be passed to QEMU via SCM_RIGHTS and added to an
fd set.

This can be combined with commands such as -drive to link file
descriptors in an fd set to a drive:

    qemu-kvm -add-fd fd=3,set=2,opaque="rdwr:/path/to/file"
             -add-fd fd=4,set=2,opaque="rdonly:/path/to/file"
             -drive file=/dev/fdset/2,index=0,media=disk

This example adds dups of fds 3 and 4, and the accompanying opaque
strings to the fd set with ID=2.  qemu_open() already knows how
to handle a filename of this format.  qemu_open() searches the
corresponding fd set for an fd and when it finds a match, QEMU
goes on to use a dup of that fd just like it would have used an
fd that it opened itself.

5f072e1f30 create struct for machine initialization arguments
This should help us to:
- More easily add or remove machine initialization arguments without
  having to change every single machine init function;
- More easily make mechanical changes involving the machine init
  functions in the future;
- Let machine initialization forward the init arguments to other
  functions more easily.

This change was half-mechanical process: first the struct was added with
the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local
variable initialization to all functions. Then the compiler helped me
locate the local variables that are unused, so they could be removed.

ac05f34924 add a boot parameter to set reboot timeout
Added an option to let qemu transfer a configuration file to bios,
"etc/boot-fail-wait", which could be specified by command
    -boot reboot-timeout=T
T have a max value of 0xffff, unit is ms.

With this option, guest will wait for a given time if not find
bootabled device, then reboot. If reboot-timeout is '-1', guest
will not reboot, qemu passes '-1' to bios by default.

This feature need the new seabios's support.

Seabios pulls the value from the fwcfg "file" interface, this
interface is used because SeaBIOS needs a reliable way of
obtaining a name, value size, and value. It in no way requires
that there be a real file on the user's host machine.

995ee2bf46 curses: don't initialize curses when qemu is daemonized
Current qemu initializes curses even if -daemonize option is
passed. This cause problem because shell prompt appears without
calling endwin().

This patch adds new function, is_daemonized(), to OS dependent
code. With this function, curses_display_init() can check that qemu is
daemonized or not. If daemonized, curses_display_init() isn't called
and the problem is avoided.

Of course, -daemonize && -curses doesn't make sense. Users shouldn't
pass the arguments at the same time. But the problem is very painful
because Ctrl-C cannot be delivered to the terminal.

f278d4947f i8259: add -no-spurious-interrupt-hack option
This patch provides a way to optionally suppress spurious interrupts,
as a workaround for systems described below:

Some old operating systems do not handle spurious interrupts well,
and qemu tends to generate them significantly more often than
real hardware.

Examples:
  - Microport UNIX System V/386 v 2.1 (ca 1987)
    (The main problem I'm fixing: Without this patch, it panics
    sporadically when accessing the hard disk.)
  - AT&T UNIX System V/386 Release 4.0 Version 2.1a (ca 1991)
    See screenshot in "QEMU Official OS Support List":
    http://www.claunia.com/qemu/objectManager.php?sClass=application&iId=9
    (I don't have this system to test.)

482f7bf86b vga: add some optional CGA compatibility hacks
This patch adds some optional compatibility hacks (default
disabled) to allow Microport UNIX to function under qemu.

I've tried to structure it to be easy to add more hacks for other
old CGA programs, if anyone ever needs them.

Microport UNIX System V/386 v 2.1 (ca 1987) tries to program
the CGA registers directly with neither the assistance of BIOS, nor
with proper handling of EGA/VGA-only registers.  Note that it didn't
work on real VGA hardware, either (although in that case, the most
obvious problems seemed to be out-of-range hsync and/or vsync
signalling, rather than the issues in this patch).

Eventually real MDA and/or CGA support might provide an alternative to
this patch, although a hybrid approach like this patch might still
be useful in marginal cases.

be52202902 Allow QEMUMachine to override reset sequencing
qemu_system_reset() function always performs the same basic actions on
all machines.  This includes running all the reset handler hooks,
however the order in which these will run is not always easily predictable.

This patch splits the core of qemu_system_reset() - the invocation of
the reset handlers - out into a new qemu_devices_reset() function.
qemu_system_reset() will usually call qemu_devices_reset(), but that
can be now overriden by a new reset method in the QEMUMachine
structure.

Individual machines can use this reset method, if necessary, to
perform any extra, machine specific initializations which have to
occur before or after the bulk of the reset handlers.  It's expected
that the method will call qemu_devices_reset() at some point, but if
the machine has really strange ordering requirements between devices
resets it could even override that with it's own reset sequence (with
great care, obviously).

For a specific example of when this might be needed: a number of
machines (but not PC) load images specified with -kernel or -initrd
directly into the machine RAM before booting the guest.  This mostly
works at the moment, but to make this actually safe requires that this
load occurs after peripheral devices are reset - otherwise they could
have active DMAs in progress which would clobber the in memory images.
Some machines (notably pseries) also have other entry conditions which
need to be set up as the last thing before executing in guest space -
some of this could be considered "emulated firmware" in the sense that
the actions of the firmware are emulated directly by qemu rather than
by executing a firmware image within the guest.  When the platform's
firmware to OS interface is sufficiently well specified, this saves
time both in implementing the "firmware" and executing it.

17c8660b0b qmp: emit the WAKEUP event when the guest is put to run
Today, the WAKEUP event is emitted when a wakeup _request_ is made.
This could be the system_wakeup command, for example.

A better semantic would be to emit the event when the guest is
already running, as that's what matters in the end. This commit does
that change.

In theory, this could break compatibility. In practice, it shouldn't
happen though, as clients shouldn't rely on timing characteristics of
the events. That is, a client relying that the guest is not running
when the event arrives may break if the event arrives after the guest
is already running.

This commit also adds the missing documentation for the WAKEUP event.
