a663fbd9e2 vnc: Wrap vnc initialization code with CONFIG_VNC
commit f8c75b2486 (vnc: Initialization stubs) removed CONFIG_VNC in vl.c
code. However qemu_find_opts("vnc") is NULL when vnc is configured out.
Crash will happen in qemu_opts_foreach() before stub vnc_init_func() is
called. This patch add it back.

0544edd88a vl: smp_parse: cleanups
No functional changes; only some code movement and removal of
dead code (impossible conditions). Also, max_cpus can be
initialized to 1, like smp_cpus, because it's either set by the
user or set to smp_cpus, when smp_cpus is set by the user, or
set to 1, when nothing is set.

37146e7eaf vl.c: Add '-L help' which lists data dirs.
QEMU compiles a list of data directories from various sources.  When
consuming a QEMU binary it's useful to be able to get this list of
data directories: a primary reason is so you can list what BIOSes or
keymaps ship with this version of QEMU.  However without reproducing
the method that QEMU uses internally, it's not possible to get the
list of data directories.

This commit adds a simple '-L help' option that just lists out the
data directories as qemu calculates them:

$ ./x86_64-softmmu/qemu-system-x86_64 -L help
/home/rjones/d/qemu/pc-bios
/usr/local/share/qemu

$ ./x86_64-softmmu/qemu-system-x86_64 -L /tmp -L help
/tmp
/home/rjones/d/qemu/pc-bios
/usr/local/share/qemu

Include the header in .c files where the macro is referenced. It's not

Instead of reusing DT_SDL for Cocoa, use DT_COCOA to indicate

configure already ensures CONFIG_COCOA and CONFIG_SDL are never
set at the same time. The only case where DT_SDL is used outside
a #ifdef CONFIG_SDL block is in the no_frame/alt_grab/ctrl_grab
check. That means the only user-visible change is that we will
start printing a warning if the SDL-specific options are used in
Cocoa mode. This is a bugfix, because no_frame/alt_grab/ctrl_grab
are not used by Cocoa code.

51b9b478cc qom: -object error messages lost location, restore it
qemu_opts_foreach() runs its callback with the error location set to
the option's location.  Any errors the callback reports use the
option's location automatically.

Commit 90998d5 moved the actual error reporting from "inside"
qemu_opts_foreach() to after it.  Here's a typical hunk:

	 if (qemu_opts_foreach(qemu_find_opts("object"),
    -                          object_create,
    -                          object_create_initial, NULL)) {
    +                          user_creatable_add_opts_foreach,
    +                          object_create_initial, &err)) {
    +        error_report_err(err);
	     exit(1);
	 }

Before, object_create() reports from within qemu_opts_foreach(), using
the option's location.  Afterwards, we do it after
qemu_opts_foreach(), using whatever location happens to be current
there.  Commonly a "none" location.

This is because Error objects don't have location information.
Problematic.

Reproducer:

    $ qemu-system-x86_64 -nodefaults -display none -object secret,id=foo,foo=bar
    qemu-system-x86_64: Property '.foo' not found

Note no location.  This commit restores it:

    qemu-system-x86_64: -object secret,id=foo,foo=bar: Property '.foo' not found

Note that the qemu_opts_foreach() bug just fixed could mask the bug
here: if the location it leaves dangling hasn't been clobbered, yet,
it's the correct one.

bab47d9a75 Sort the fw_cfg file list
Entries are inserted in filename order instead of being

Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Added machine type handling for compatibility.  This was
a fairly complex change, this will preserve the order of fw_cfg
for older versions no matter what order the firmware files
actually come in.  A list is kept of the correct legacy order
and the entries will be inserted based upon their order in
the list.  Except that some entries are ordered (in a specific
area of the list) based upon what order they appear on the
command line.  Special handling is added for those entries.

efdaf797de vl: Move cpu_synchronize_all_states() into qemu_system_reset()
There are currently 3 calls to qemu_system_reset() in vl.c.  Two of them
are immediately preceded by a cpu_synchronize_all_states9) and the
remaining one should be.

The one which doesn't is the very first reset called directly from main().
Without a cpu_synchronize_all_states(), kvm_vcpu_dirty is false at this
point from the earlier cpu_synchronize_all_post_init().  That's incorrect
because the reset path is quite likely to update the CPU state, and that
updated state should be pushed back to KVM, not overwritten with stale
data pushed to KVM immediately after init.

This patch moves the call to cpu_synchronize_all_states() into
qemu_system_reset() for safety, so it is always called.  AFAICT this should
be safe for the handful of callers outside vl.c - these all appear to be in
places where the cpu state is already synchronized so the extra call
will be a no-op.

0e066b2cc5 input-linux: switch over to -object
This patches makes input-linux use -object instead of a new command line
switch.  So, instead of the switch ...

    -input-linux /dev/input/event$nr

... you must create an object this way:

    -object input-linux,id=$name,evdev=/dev/input/event$nr

Bonus is that you can hot-add and hot-remove them via monitor now.

3514552e04 qemu-log: new option -dfilter to limit output
When debugging big programs or system emulation sometimes you want both
the verbosity of cpu,exec et all but don't want to generate lots of logs
for unneeded stuff. This patch adds a new option -dfilter which allows
you to specify interesting address ranges in the form:

  -dfilter 0x8000..0x8fff,0xffffffc000080000+0x200,...

Then logging code can use the new qemu_log_in_addr_range() function to
decide if it will output logging information for the given range.

e0d2bd5195 input: linux evdev support
This patch adds support for reading input events directly from linux
evdev devices and forward them to the guest.  Unlike virtio-input-host
which simply passes on all events to the guest without looking at them
this will interpret the events and feed them into the qemu input
subsystem.

Therefore this is limited to what the qemu input subsystem and the
emulated input devices are able to handle.  Also there is no support for
absolute coordinates (tablet/touchscreen).  So we are talking here about
basic mouse and keyboard support.

The advantage is that it'll work without virtio-input drivers in the
guest, the events are delivered to the usual ps/2 or usb input devices
(depending on what the machine happens to have).  And for keyboards
qemu is able to switch the keyboard between guest and host on hotkey.
The hotkey is hard-coded for now (both control keys), initialy the
guest owns the keyboard.

Probably most useful when assigning vga devices with vfio and using a
physical monitor instead of vnc/spice/gtk as guest display.

Usage:  Add '-input-linux /dev/input/event<nr>' to the qemu command
line.  Note that udev has rules which populate /dev/input/by-{id,path}
with static names, which might be more convinient to use.

43fa1e0bd9 vl: Reset location after handling command-line arguments
After looping through all command-line arguments, error location
info becomes obsolete, and any function calling error_report()
will print misleading information. This breaks error reporting
for some option handling, like:

  $ qemu-system-x86_64 -icount rr=x -vnc :0
  qemu-system-x86_64: -vnc :0: Invalid icount rr option: x

  $ qemu-system-x86_64 -m size= -vnc :0
  qemu-system-x86_64: -vnc :0: missing 'size' option value

Fix this by resetting location info as soon as we exit the
command-line handling loop.

With this, replay_configure() and set_memory_options() won't
print any location info yet, but at least they won't print
incorrect information.

34f405ae6d vl.c: Fix regression in machine error message
Commit e1ce0c3cb (vl.c: fix regression when reading machine type
from config file) fixed the error message when the machine type
was supplied inside the config file. However now the option name
is not displayed correctly if the error happens when the machine
is specified at command line.

Running
    ./x86_64-softmmu/qemu-system-x86_64 -M q35-1.5 -redir tcp:8022::22
will result in the error message:
    qemu-system-x86_64: -redir tcp:8022::22: unsupported machine type
    Use -machine help to list supported machines

Fixed it by restoring the error location and also extracted the code
dealing with machine options into a separate function.

90998d5896 qom: add helpers for UserCreatable object types
The QMP monitor code has two helper methods object_add
and qmp_object_del that are called from several places
in the code (QMP, HMP and main emulator startup).

The HMP and main emulator startup code also share
further logic that extracts the qom-type & id
values from a qdict.

We soon need to use this logic from qemu-img, qemu-io
and qemu-nbd too, but don't want those to depend on
the monitor, nor do we want to duplicate the code.

To avoid this, move some code out of qmp.c and hmp.c
adding new methods to qom/object_interfaces.c

 - user_creatable_add - takes a QDict holding a full
   object definition & instantiates it
 - user_creatable_add_type - takes an ID, type name,
   and QDict holding object properties & instantiates
   it
 - user_creatable_add_opts - takes a QemuOpts holding
   a full object definition & instantiates it
 - user_creatable_add_opts_foreach - variant on
   user_creatable_add_opts which can be directly used
   in conjunction with qemu_opts_foreach.
 - user_creatable_del - takes an ID and deletes the
   corresponding object

The existing code is updated to use these new methods.
