81b2b81062 fw_cfg: insert fw_cfg file blobs via qemu cmdline
Allow user supplied files to be inserted into the fw_cfg
device before starting the guest. Since fw_cfg_add_file()
already disallows duplicate fw_cfg file names, qemu will
exit with an error message if the user supplies multiple
blobs with the same fw_cfg file name, or if a blob name
collides with a fw_cfg name programmatically added from
within the QEMU source code. A warning message will be
printed if the fw_cfg item name does not begin with the
prefix "opt/", which is recommended for external, user
provided blobs.

1640b200d5 QemuOpts: Drop qemu_opt_foreach() parameter abort_on_failure
When the argument is non-zero, qemu_opt_foreach() stops on callback
returning non-zero, and returns that value.

When the argument is zero, it doesn't stop, and returns the callback's
value from the last iteration.

The two callers that pass zero could just as well pass one:

* qemu_spice_init()'s callback add_channel() either returns zero or
  exit()s.

* config_write_opts()'s callback config_write_opt() always returns
  zero.

Drop the parameter, and always stop.

a4c7367f7d QemuOpts: Drop qemu_opts_foreach() parameter abort_on_failure
When the argument is non-zero, qemu_opts_foreach() stops on callback
returning non-zero, and returns that value.

When the argument is zero, it doesn't stop, and returns the bit-wise
inclusive or of all the return values.  Funky :)

The callers that pass zero could just as well pass one, because their
callbacks can't return anything but zero:

* qemu_add_globals()'s callback qdev_add_one_global()

* qemu_config_write()'s callback config_write_opts()

* main()'s callbacks default_driver_check(), drive_enable_snapshot(),
  vnc_init_func()

Drop the parameter, and always stop.

8122928a52 vl: Fail right after first bad -object
Failure to create an object with -object is a fatal error.  However,
we delay the actual exit until all -object are processed.  On the one
hand, this permits detection of genuine additional errors.  On the
other hand, it can muddy the waters with uninteresting additional
errors, e.g. when a later -object tries to reference a prior one that
failed.

We generally stop right on the first bad option, so do that for
-object as well.

use_virtcon, use_sclp, no_floppy, no_cdrom, default_display,
compat_props, and hw_version.

97edf3bd5e gtk: add opengl support, using egl
This adds opengl rendering support to the gtk ui, using egl.
It's off by default for now, use 'qemu -display gtk,gl=on'
to play with this.

Note that gtk got native opengl support with release 3.16.
There most likely will be a separate implementation for 3.16+,
using the native gtk opengl support.  This patch covers older
versions (and for the time being 3.16 too, hopefully without
rendering quirks).

f05f47bb5f bootdevice: check boot order argument validation before vm running
Either 'once' option or 'order' option can take effect for -boot at
the same time, that is say initial startup processing can check only
one. And pc.c's set_boot_dev() fails when its boot order argument
is invalid. This patch provide a solution fix this problem:

 1. If "once" is given, register reset handler to restore boot order.

 2. Pass the normal boot order to machine creation.  Should fail when
   the normal boot order is invalid.

 3. If "once" is given, set it with qemu_boot_set().  Fails when the
   once boot order is invalid.

 4. Start the machine.

 5. On reset, the reset handler calls qemu_boot_set() to restore boot
   order.  Should never fail.

f43e47dbf6 QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix use
qemu_opt_set() is a wrapper around qemu_opt_set() that reports the
error with qerror_report_err().

Most of its users assume the function can't fail.  Make them use
qemu_opt_set_err() with &error_abort, so that should the assumption
ever break, it'll break noisily.

Just two users remain, in util/qemu-config.c.  Switch them to
qemu_opt_set_err() as well, then rename qemu_opt_set_err() to
qemu_opt_set().

Some are called do_COMMAND() (old ones, usually), some hmp_COMMAND(),

Normalize to hmp_COMMAND(), where COMMAND is exactly the command name
with '-' replaced by '_'.

Exceptions:

* do_device_add() and client_migrate_info() *not* renamed to
  hmp_device_add(), hmp_client_migrate_info(), because they're also
  QMP handlers.  They still need to be converted to QAPI.

* do_memory_dump(), do_physical_memory_dump(), do_ioport_read(),
  do_ioport_write() renamed do hmp_* instead of hmp_x(), hmp_xp(),
  hmp_i(), hmp_o(), because those names are too cryptic for my taste.

* do_info_help() renamed to hmp_info_help() instead of hmp_info(),
  because it only covers help.

46ede58bb4 vl: Fix bogus error message for implied mon ID clashing
monitor_parse() desugars --monitor, --qmp and -qmp-pretty to --mon.
The ID it picks can clash with a user-specified ID.  When it happens,
the error message is misleading.

Reproducer:

    $ qemu --mon id=compat_monitor0 --monitor stdio

Message before the patch:

    duplicate chardev: compat_monitor0

There's no "duplicate chardev" here.  The problem is a duplicate
monitor ID.  Moreover, the message provides no clue which option
caused the problem.  The patch changes the message to:

    qemu: --monitor stdio: Duplicate ID 'compat_monitor0' for mon

monitor_parse() is also used for creating a default monitor, but
that's not done when the user specifies a monitor, so an ID clash is
impossible then.

f8b6f8edac hw/ppc: modified the condition for usb controllers to be created for some ppc machines
Some ppc machines create a default usb controller based on a 'machine condition'.
Until now the logic was: create the usb controller if:
 -  the usb option was supplied in cli and value is true or
 -  the usb option was absent and both set_defaults and the machine
    condition were true.

Modified the logic to:
Create the usb controller if:
 - the machine condition is true and defaults are enabled or
 - the usb option is supplied and true.

The main for this is to simplify the usb_enabled method.

a38bb0792c Add the "-semihosting-config" option.
The usual semihosting behaviour is to process the system calls locally and
return; unfortuantelly the initial implementation dinamically changed the
target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb,
is not implemented. The result was that during debug sessions the semihosting
calls were discarded.

This patch adds a configuration variable and an option to set it on the
command line:

    -semihosting-config [enable=on|off,]target=native|gdb|auto

This option enables semihosting and defines where the semihosting calls will
be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which
means 'gdb' during debug sessions and 'native' otherwise.

33cd52b5d7 sysbus: Make devices spawnable via -device
Now that we can properly map sysbus devices that haven't been connected to
something forcefully by C code, we can allow the -device command line option
to spawn them.

For machines that don't implement dynamic sysbus assignment in their board
files we add a new bool "has_dynamic_sysbus" to the machine class.
When that property is false (default), we bail out when we see dynamically
spawned sysbus devices, like we did before.

caad057bb6 smbios: Encode UUID according to SMBIOS specification
Differently from older versions, SMBIOS version 2.6 is explicit about
the encoding of UUID fields:

> Although RFC 4122 recommends network byte order for all fields, the PC
> industry (including the ACPI, UEFI, and Microsoft specifications) has
> consistently used little-endian byte encoding for the first three fields:
> time_low, time_mid, time_hi_and_version. The same encoding, also known as
> wire format, should also be used for the SMBIOS representation of the UUID.
>
> The UUID {00112233-4455-6677-8899-AABBCCDDEEFF} would thus be represented
> as 33 22 11 00 55 44 77 66 88 99 AA BB CC DD EE FF.

The dmidecode tool implements this and decodes the above "wire format"
when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when
we started building the SMBIOS entry point inside QEMU, on commit
c97294ec1b.

Change smbios_build_type_1_table() to encode the UUID as specified.

To make sure we won't change the guest-visible UUID when upgrading to a
newer QEMU version, keep the old behavior on pc-*-2.1 and older.

2709f26395 well-defined listing order for machine types
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.

Effects on the x86_64 output:

fee78fd6d2 pidfile: stop making pidfile error a special case
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().

522abf6999 vl.c: Fix Coverity complaining for vmstate_dump_file
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.

817ef04db2 Make qemu_shutdown_requested signal-safe
qemu_shutdown_requested may be interrupted by qemu_system_killed. If the
latter sets shutdown_requested after qemu_shutdown_requested has read it
but before it was cleared, the shutdown event is lost. Fix this by using
atomic_xchg.

This provides a different fix for the problem which commit 15124e142
attempts to deal with. That commit breaks use of ^C to drop into gdb,
and so this approach is better (and 15124e142 can be reverted).

7797a73947 hmp: Remove "info pcmcia"
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.

1602651833 pc/vl: Add units-per-default-bus property
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.

a66c9dc734 blockdev: Orphaned drive search
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.

If we configure mlock=on and memory policy=bind at the same time,
It will consume lots of time for system to treat with memory,

2f78e491d7 async: aio_context_new(): Handle event_notifier_init failure
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.

This commit adds an error message on failure:

 # qemu [...] -object iothread,id=iothread0 -object iothread,id=iothread1
 qemu: Failed to initialize event notifier: Too many open files in system

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

bc78cff975 trace: add qemu_system_powerdown_request and qemu_system_shutdown_request trace events
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.

abfd9ce341 migration: dump vmstate info as a json file for static analysis
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.

c87b152072 pc & q35: Add new machine opt max-ram-below-4g
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.

74892d2468 vl: allow other threads to do qemu_system_vmstop_request
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.

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.

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

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.

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

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'

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.

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.

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)

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.
