Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine
list") broke the ordering of the machine types in the user-visible output
of
qemu-system-XXXX -M \?
This occurred because registration was rebased from a manually maintained
linked list to GLib hash tables:
qemu_register_machine()
type_register()
type_register_internal()
type_table_add()
g_hash_table_insert()
and because the listing was rebased accordingly, from the traversal of the
list to the traversal of the hash table (rendered as an ad-hoc list):
machine_parse()
object_class_get_list(TYPE_MACHINE)
object_class_foreach()
g_hash_table_foreach()
The current order is a "random" one, for practical purposes, which is
annoying for users.
Introduce new members QEMUMachine.family and MachineClass.family, allowing
machine types to be "clustered". Introduce a comparator function that
establishes a total ordering between machine types, ordering machine types
in the same family next to each other. In machine_parse(), list the
supported machine types sorted with the comparator function.
The comparator function:
- sorts whole families before standalone machine types,
- sorts whole families between each other in alphabetically increasing
order,
- sorts machine types inside the same family in alphabetically decreasing
order,
- sorts standalone machine types between each other in alphabetically
increasing order.
After this patch, all machine types are considered standalone, and
accordingly, the output is alphabetically ascending. This will be refined
in the following patches.

In case of -daemonize, we write non-zero to the daemon
pipe only if pidfile creation failed, so the parent will
report error about pidfile problem. There's no need to
make special case for this, since all other errors are
reported by the child just fine. Let the parent report
error and simplify logic in os_daemonize().
This way, we don't need os_pidfile_error() function, since
it only prints error now, so put the error reporting printf
into the only place where qemu_create_pidfile() is called,
in vl.c.
While at it, fix wrong indentation in os_daemonize().

commit abfd9ce3(migration: dump vmstate info as a json
file for static analysis) introduce a new command,
'-dump-vmstate', that takes a filename
as an argument. When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.
However, only one instance of the -dump-vmstate option is supported.
If more were given, the vmstate_dump_file variable would be overwritten.
This fix also helps silence a Coverity error.

atomic_xchg.
This provides a different fix for the problem which commit 15124e142

This command lists PCMCIA sockets and cards. Only a few ARM boards
have sockets (akita, borzoi, connex, mainstone, spitz, terrier, tosa,
verdex, z2), the only card is the DSCM-1xxxx Hitachi Microdrive (qdev
"microdrive"), and it is only inserted during machine init, if ever.
So this command doesn't really tell anybody anything new so far.
Moreover, pcmcia_socket_unregister() has a use-after-free bug, flagged
by Coverity. Has never been used, because there has never been code
to eject a PCMCIA card.
Not worth fixing & converting to QMP. Remove it.

This patch adds the 'units_per_default_bus' property which
allows individual boards to declare their desired
index => (bus,unit) mapping for their default HBA, so that
boards such as Q35 can specify that its default if_ide HBA,
AHCI, only accepts one unit per bus.
This property only overrides the mapping for drives matching
the block_default_type interface.
This patch also adds this property to *all* past and present
Q35 machine types. This retroactive addition is justified
because the previous erroneous index=>(bus,unit) mappings
caused by lack of such a property were not utilized due to
lack of initialization code in the Q35 init routine.
Further, semantically, the Q35 board type has always had the
property that its default HBA, AHCI, only accepts one unit per
bus. The new code added to add devices to drives relies upon
the accuracy of this mapping. Thus, the property is applied
retroactively to reduce complexity of allowing IDE HBAs with
different units per bus.
Examples:
Prior to this patch, all IDE HBAs were assumed to use 2 units
per bus (Master, Slave). When using Q35 and AHCI, however, we
only allow one unit per bus.
-hdb foo.qcow2 would become index=1, or bus=0,unit=1.
-hdd foo.qcow2 would become index=3, or bus=1,unit=1.
-drive file=foo.qcow2,index=5 becomes bus=2,unit=1.
These are invalid for AHCI. They now become, under Q35 only:
-hdb foo.qcow2 --> index=1, bus=1, unit=0.
-hdd foo.qcow2 --> index=3, bus=3, unit=0.
-drive file=foo.qcow2,index=5 --> bus=5,unit=0.
The mapping is adjusted based on the fact that the default IF
for the Q35 machine type is IF_IDE, and units-per-default-bus
overrides the IDE mapping from its default of 2 units per bus
to just 1 unit per bus.

When users use command line options like -hda, -cdrom,
or even -drive if=ide, it is up to the board initialization
routines to pick up these drives and create backing
devices for them.
Some boards, like Q35, have not been doing this.
However, there is no warning explaining why certain
drive specifications are just silently ignored,
so this function adds a check to print some warnings
to assist users in debugging these sorts of issues
in the future.
This patch will not warn about drives added with if_none,
for which it is not possible to tell in advance if
the omission of a backing device is an issue.
A warning in these cases is considered appropriate.

On a system with a low limit of open files the initialization
of the event notifier could fail and QEMU exits without printing any
error information to the user.
The problem can be easily reproduced by enforcing a low limit of open
files and start QEMU with enough I/O threads to hit this limit.
The same problem raises, without the creation of I/O threads, while
QEMU initializes the main event loop by enforcing an even lower limit of
open files.

Add Intel IOMMU emulation to q35 chipset and expose it to the guest.
1. Add a machine option. Users can use "-machine iommu=on|off" in the command
line to enable/disable Intel IOMMU. The default is off.
2. Accroding to the machine option, q35 will initialize the Intel IOMMU and
use pci_setup_iommu() to setup q35_host_dma_iommu() as the IOMMU function for
the pci bus.
3. q35_host_dma_iommu() will return different address space according to the
bus_num and devfn of the device.

We have the experience that the guest doesn't stop successfully
though it was instructed to shut down.
The root cause may be not in QEMU mostly. However, QEMU is often
suspected at the beginning just because the issue occurred in
virtualization environment.
Therefore, we need to affirm that QEMU received the shutdown
request and raised ACPI irq from "virsh shutdown" command,
virt-manger or stopping QEMU process to the VM .
So that we can affirm the problems was belonged to the Guset OS
rather than the QEMU itself.
When we stop guests by "virsh shutdown" command or virt-manger,
or stopping QEMU process, qemu_system_powerdown_request() or
qemu_system_shutdown_request() is called. Then the below functions
in main_loop_should_exit() of Vl.c are called roughly in the
following order.
if (qemu_powerdown_requested())
qemu_system_powerdown()
monitor_protocol_event(QEVENT_POWERDOWN, NULL)
OR
if(qemu_shutdown_requested()}
monitor_protocol_event(QEVENT_SHUTDOWN, NULL);
The tracepoint of monitor_protocol_event() already exists, but no
tracepoints are defined for qemu_system_powerdown_request() and
qemu_system_shutdown_request(). So this patch adds two tracepoints for
the two functions. We believe that it will become much easier to
isolate the problem mentioned above by these tracepoints.

This commit adds a new command, '-dump-vmstate', that takes a filename
as an argument. When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.
The JSON-format output can then be used to compare the vmstate info for
different QEMU versions, specifically to test whether live migration
would break due to changes in the vmstate data.
A Python script that compares the output of such JSON dumps is included
in the following commit.

This is a pc & q35 only machine opt.
If you add enough PCI devices then all mmio for them will not fit
below 4G which may not be the layout the user wanted. This allows
you to increase the below 4G address space that PCI devices can use
(aka decrease ram below 4G) and therefore in more cases not have any
mmio that is above 4G.
For example using "-machine pc,max-ram-below-4g=2G" on the command
line will limit the amount of ram that is below 4G to 2G.
Note: this machine option cannot be used to increase the amount
of ram below 4G.

There patch protects vmstop_requested with a lock and introduces
qemu_system_vmstop_request_prepare.
Together with the new call to qemu_vmstop_requested in vm_start,
qemu_system_vmstop_request_prepare avoids a race where the VM could remain
stopped even though the iostatus of a block device has already been set
(for example).
qemu_system_vmstop_request_prepare however also lets the caller thread
delay observation of the state change until it has itself communicated
that change to the user. This delay avoids any possibility of a wrong
reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.

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.

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.

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.

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'

Some machine (like pseries) initialization code determines if it has

vga_interface_type is evaluated to VGA_NONE even if a VGA is added

device configured. Add a new VGA device type to indicate that it has a

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).

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.

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

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)

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.

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.

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.

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

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.

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.

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

in a customer's system, we try to understand the problem by

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

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
$ upstream-qemu -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on
$ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=kvm,usb=on

xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error
xen be core: can't open xen interface
failed to initialize Xen: Operation not permitted
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.

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

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.

2. If -boot is given multiple times, options accumulate, just like for

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.

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.

memory locking is needed. Also, in the scenario with untrusted
guests, latency improvement due to mlock is desired.
This patch introduces a following new option to mlock guest and
qemu memory:
-realtime mlock=on|off

We have only one DisplayState, so there is no need for the "next"
linking, rip it. Also consolidate all displaystate initialization
into init_displaystate(). This function is called by vl.c after
creating the devices (and thus all QemuConsoles) and before
initializing DisplayChangeListensers (aka gtk/sdl/vnc/spice ui).

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.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

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.

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.
v2: add HALT entry in get_boot_devices_list()
v3: rebase to latest qemu upstream
