243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

virtio-input-hid.c undefines CONFIG_CURSES before including
ui/console.h. However since commits e2f82e924d and b0766612d1
that header does not have behaviour dependent on CONFIG_CURSES.

167f1667b1 adb: fix adb-mouse read length and revert disable-reg3-direct-writes workaround
Commit 84051eb400 "adb: add property to disable direct reg 3 writes" introduced
a workaround for spurious writes to ADB register 3 when MacOS 9 enables
autopoll on the mouse device. Further analysis shows that the problem is that
only a partial request is sent, and since the len parameter is ignored then
stale data from the previous request is used causing the incorrect address
assignment.

Remove the disable-reg3-direct-writes workaround and instead check the length
parameter when the write is attempted, discarding the invalid request.

b69c3c21a5 qdev: Unrealize must not fail
Devices may have component devices and buses.

Device realization may fail.  Realization is recursive: a device's
realize() method realizes its components, and device_set_realized()
realizes its buses (which should in turn realize the devices on that
bus, except bus_set_realized() doesn't implement that, yet).

When realization of a component or bus fails, we need to roll back:
unrealize everything we realized so far.  If any of these unrealizes
failed, the device would be left in an inconsistent state.  Must not
happen.

device_set_realized() lets it happen: it ignores errors in the roll
back code starting at label child_realize_fail.

Since realization is recursive, unrealization must be recursive, too.
But how could a partly failed unrealize be rolled back?  We'd have to
re-realize, which can fail.  This design is fundamentally broken.

device_set_realized() does not roll back at all.  Instead, it keeps
unrealizing, ignoring further errors.

It can screw up even for a device with no buses: if the lone
dc->unrealize() fails, it still unregisters vmstate, and calls
listeners' unrealize() callback.

bus_set_realized() does not roll back either.  Instead, it stops
unrealizing.

Fortunately, no unrealize method can fail, as we'll see below.

To fix the design error, drop parameter @errp from all the unrealize
methods.

Any unrealize method that uses @errp now needs an update.  This leads
us to unrealize() methods that can fail.  Merely passing it to another
unrealize method cannot cause failure, though.  Here are the ones that
do other things with @errp:

* virtio_serial_device_unrealize()

  Fails when qbus_set_hotplug_handler() fails, but still does all the
  other work.  On failure, the device would stay realized with its
  resources completely gone.  Oops.  Can't happen, because
  qbus_set_hotplug_handler() can't actually fail here.  Pass
  &error_abort to qbus_set_hotplug_handler() instead.

* hw/ppc/spapr_drc.c's unrealize()

  Fails when object_property_del() fails, but all the other work is
  already done.  On failure, the device would stay realized with its
  vmstate registration gone.  Oops.  Can't happen, because
  object_property_del() can't actually fail here.  Pass &error_abort
  to object_property_del() instead.

* spapr_phb_unrealize()

  Fails and bails out when remove_drcs() fails, but other work is
  already done.  On failure, the device would stay realized with some
  of its resources gone.  Oops.  remove_drcs() fails only when
  chassis_from_bus()'s object_property_get_uint() fails, and it can't
  here.  Pass &error_abort to remove_drcs() instead.

Therefore, no unrealize method can fail before this patch.

device_set_realized()'s recursive unrealization via bus uses
object_property_set_bool().  Can't drop @errp there, so pass
&error_abort.

We similarly unrealize with object_property_set_bool() elsewhere,
always ignoring errors.  Pass &error_abort instead.

Several unrealize methods no longer handle errors from other unrealize
methods: virtio_9p_device_unrealize(),
virtio_input_device_unrealize(), scsi_qdev_unrealize(), ...
Much of the deleted error handling looks wrong anyway.

One unrealize methods no longer ignore such errors:
usb_ehci_pci_exit().

Several realize methods no longer ignore errors when rolling back:
v9fs_device_realize_common(), pci_qdev_unrealize(),
spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(),
virtio_device_realize().

d2623129a7 qom: Drop parameter @errp of object_property_add() & friends
The only way object_property_add() can fail is when a property with
the same name already exists.  Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.

Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent.  Parentage is
also under program control, so this is a programming error, too.

We have a bit over 500 callers.  Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.

The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.

Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.  ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.

When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.

Drop parameter @errp and assert the preconditions instead.

There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification".  Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

Hi,

 There are a few places where such substitution isn't possible. For
 those places, it seems reasonable to use a specific setter method
 instead, and keep the user_creatable = false. In other places,
 proper usage of qdev or other facilies is the solution.
 
 The serial code wasn't converted to qdev, which makes it a bit more
 archaic to deal with. Let's convert it first, so we can more easily
 embed it from other devices, and re-export some properties and drop
 QDEV_PROP_PTR usage.

54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h.  Include hw/qdev-core.h there
instead.

hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

e0e312f352 build: switch to Kconfig
The make_device_config.sh script is replaced by minikconf, which
is modified to support the same command line as its predecessor.

The roots of the parsing are default-configs/*.mak, Kconfig.host and
hw/Kconfig.  One difference with make_device_config.sh is that all symbols
have to be defined in a Kconfig file, including those coming from the
configure script.  This is the reason for the Kconfig.host file introduced
in the previous patch. Whenever a file in default-configs/*.mak used
$(...) to refer to a config-host.mak symbol, this is replaced by a
Kconfig dependency; this part must be done already in this patch
for bisectability.

Whenever a symbol is referenced from multiple subdirectories, the

These symbols have to be added manually to the Kconfig files.

Kconfig.host and hw/Kconfig were created manually.

Fix this by replacing the culprit fprintf(stderr) calls by a more

are left untouched.

fb06411210 qmp hmp: Make system_wakeup check wake-up support and run state
The qmp/hmp command 'system_wakeup' is simply a direct call to
'qemu_system_wakeup_request' from vl.c. This function verifies if
runstate is SUSPENDED and if the wake up reason is valid before
proceeding. However, no error or warning is thrown if any of those
pre-requirements isn't met. There is no way for the caller to
differentiate between a successful wakeup or an error state caused
when trying to wake up a guest that wasn't suspended.

This means that system_wakeup is silently failing, which can be
considered a bug. Adding error handling isn't an API break in this
case - applications that didn't check the result will remain broken,
the ones that check it will have a chance to deal with it.

Adding to that, the commit before previous created a new QMP API called
query-current-machine, with a new flag called wakeup-suspend-support,
that indicates if the guest has the capability of waking up from suspended
state. Although such guest will never reach SUSPENDED state and erroring
it out in this scenario would suffice, it is more informative for the user
to differentiate between a failure because the guest isn't suspended versus
a failure because the guest does not have support for wake up at all.

All this considered, this patch changes qmp_system_wakeup to check if
the guest is capable of waking up from suspend, and if it is suspended.
After this patch, this is the output of system_wakeup in a guest that
does not have wake-up from suspend support (ppc64):

(qemu) system_wakeup
wake-up from suspend is not supported by this guest
(qemu)

And this is the output of system_wakeup in a x86 guest that has the
support but isn't suspended:

(qemu) system_wakeup
Unable to wake up: guest is not in suspended state
(qemu)

a1f2ed2ad8 ps2: prevent changing irq state on save and load
Commit 2858ab09e6 changed
PS/2 keyboard/mouse buffers to the standard size. However, its state
may change when migrating from the old buffer size and therefore irq needs
updating. But this change made wrong, because it throws the whole queue
if there are too much data instead of cropping it.

That commit also updates irq (because the queue state may change).
But updating the irq may change the VM state (and determinism of
the execution). E.g., when replaying the execution, one may save
the VM state and the state of the interrupt controller will be updated
at the moment of saving, instead of using the recorded update events.

This patch makes the queue update deterministic: it removes the update_irq
call and crops the queue to prevent losing the characters and changing
the required irq status.

In commit 802cbcb730, most issues have been fixed when qemu guest
migration. But the queue size still need to check whether is equal to
PS2_QUEUE_SIZE. If yes, the wptr should set as 0. Or, wptr would larger
than PS2_QUEUE_SIZE and never come back when ps2_queue_noirq is called.
This could lead to OOB access, add check to avoid it.

This fixes an issue by adding bounds checking to multi-byte packets
where the PS/2 mouse data stream may become corrupted due to data being

Interrupts for Multi-byte responses are postponed until the final byte

143c04c7e0 ps2: Clear the PS/2 queue and obey disable
This allows guest's to correctly reinitialize and identify the mouse
should the guest decide to re-scan or reset during mouse input events.

When the guest sends the "Identify" command, due to the PC's hardware
architecutre it is impossible to reliably determine the response from
the command amongst other streaming data, such as mouse or keyboard
events. Standard practice is for the guest to disable the device and
then issue the identify command, so this must be obeyed.

NB, the virtio-input device reports a bitmask to the guest driver that
has a bit set for each Linux keycode that the host is able to send to
the guest.

Thus by adding these extra key mappings we are technically changing the
host<->guest ABI. This would also happen any time we defined new mappings
for QEMU keycodes in future.

When a keycode is removed from the list of possible keycodes that host can
send to the guest, it means that the guest OS will think it is possible
to receive a key that in pratice can never be generated, which is harmless.

When a keycode is added to the list of possible keycodes that the host can
send to the guest, it means that the guest OS can see an unexpected event.
The Linux virtio_input.c driver code simply forwards this event to the
input_event() method in the Linux input subsystem. This in turn calls
input_handle_event(), which then calls input_get_disposition(). This method
checks if the input event is present in the permitted keys bitmap, and if
not returns INPUT_IGNORE_EVENT. Thus the unexpected event will get dropped,
which is harmless.

If the guest OS reboots, or otherwise re-initializes the virt-input device,
it will read the new keycode bitmap. No matter how many keys are defined,
the config space has a fixed 128 byte bitmap. There is, however, a size
field defiend which says how many bytes in the bitmap are used. So the guest
OS reads the size of the bitmap, and then it reads the data from bitmap upto
the designated size. So if the guest OS re-initializes at precisely the time
that QEMU is migrated across versions, in the worst case, it could conceivably
read the old size field, but then get the newly updated bitmap.  If a key were
added this is harmless, since it simply means it may not process the newly
added key. If a key were removed, then it could be readnig a byte from the
bitmap that was not initialized. Fortunately QEMU always memsets() the entire
bitmap to 0, prior to setting keybits. Thus the guest OS will simply read
zeros, which is again harmless.

Based on this analysis, it is believed that there is no need to preserve the
virtio-input-hid keymaps across migration, as the host<->guest ABI change is
harmless and self-resolving at time of guest reboot.

NB, this behaviour should perhaps be formalized in the virtio-input spec
to declare how guest OS drivers should be written to be robust in their
handling of the potentially changable key bitmaps.

wheel is used. This caused virtio_input_send() to be called twice each

This commit adds a check for the button down state and only calls

This difference is pretty benign, since of all the operating systems I have
checked (Linux, FreeBSD and OpenStack), none bother to check the leading two
bytes anyway. This change none the less makes the ps2 device better follow real
hardware behaviour.

620775d1d8 ps2: fix scancodes sent for Alt-Print key combination (aka SysRq)
The 'Print' key is special in the AT set 1 / set 2 scancode definitions.

An unmodified 'Print' key is supposed to send

 AT Set 1:  e0 2a e0 37 (Down)  e0 b7 e0 aa (Up)
 AT Set 2:  e0 12 e0 7c (Down)  e0 f0 7c e0 f0 12 (Up)

which QEMU gets right. When pressed in combination with the 'Alt_L' or 'Alt_R'
keys (which signify SysRq), the scancodes are required to follow a different
scheme. With Alt_L, the expected sequences are

 AT set 1:  38, 54 (Down) d4, b8 (Up)
 AT set 2:  11, 84 (Down) f0 84, f0 11 (Up)

And with Alt_R

 AT set 1:  e0 38, 54 (Down) d4, e0 b8 (Up)
 AT set 2:  e0 11, 84 (Down) f0 84, f0 e0 11 (Up)

It is actually slightly more complicated than that, because (according results
of 'showkey -s', keyboards will in fact first release the currently pressed
modifier before sending the sequence above (which effectively re-presses &
then releases the modifier) and finally re-press the original modifier
afterwards. IOW, with Alt_L we need to send

 AT set 1:  b8, 38, 54 (Down) d4, b8, 38 (Up)
 AT set 2:  f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up)

And with Alt_R

 AT set 1:  e0 b8, e0 38, 54 (Down) d4, e0 b8, e0 38 (Up)
 AT set 2:  e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up)

The AT set 3 scancodes have no special handling for Alt-Print.

Rather than fixing the handling of the 'print' key in the ps2 driver to consider
the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq'
key name:

  commit f2289cb692
  Author: balrog <balrog@c046a42c-6fe2-441c-8c8c-71466251a162>
  Date:   Wed Jun 4 10:14:16 2008 +0000

    Add sysrq to key names known by "sendkey".

    Adding sysrq keycode to the table enabling running sysrq debugging in
    the guest via the monitor sendkey command, like:

    (qemu) sendkey alt-sysrq-t

    Tested on x86-64 target and Linux guest.

    Signed-off-by: Ryan Harper <ryanh@us.ibm.com>

With this patch QEMU would send

 AT set 1:  38, 54 (Down) d4, b8 (Up)
 AT set 2:  11, 84 (Down) f0 84, f0 11 (Up)

but this doesn't match what actual real keyboards send, as it is not releasing
the original modifier & pressing it again afterwards. In addition the original
problem remains, and a new problem was added:

  - The sequence 'alt-print-t' is still broken, acting as if 'print-t' was
    requested
  - The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence
    tot he guest os (bare 0x54)

To deal with this mess we make these changes to the ps2 code, so that we track
the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can
vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key
modifier state

Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD
and OpenSolaris), none of them actually bother to validate the full sequences
for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and
trigger based off "e0 37" alone. The latter two byte sequence is what keyboards
send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.

f4924974c7 virtio-input: send rel-wheel events for wheel buttons
qemu uses wheel-up/down button events for mouse wheel input, however
linux applications typically want REL_WHEEL events.

This fixes wheel with linux guests. Tested with X11/wayland, and
windows virtio-input driver.

Based on a patch from Marc.
Added property to enable/disable wheel axis.

44b1ff319c migration: pre_save return int
Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.

Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.

Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

check that there are no cases with additional printf flags before '#'
> find . -name trace-events | xargs grep "%[-+ 0'I]+#" | wc -l
0

check that there are no wrong usage of '#' and '0x' together
> find . -name trace-events | xargs grep '0x%#' | wc -l
0

fix the problem
> find . -name trace-events | xargs sed -i 's/%#/0x%/g'

[Eric Blake noted that xargs grep '%[-+ 0'I]+#' should be xargs grep
"%[-+ 0'I]+#" instead so the shell quoting is correct.

d2164ad35c vmstate: error hint for failed equal checks
In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug,
but it's actually the best we can do. Especially in these cases a verbose
error message is required.

Let's introduce infrastructure for specifying a error hint to be used if
equal check fails. Let's do this by adding a parameter to the _EQUAL
macros called _err_hint. Also change all current users to pass NULL as
last parameter so nothing changes for them.

cf83f14005 shutdown: Add source information to SHUTDOWN and RESET
Time to wire up all the call sites that request a shutdown or
reset to use the enum added in the previous patch.

It would have been less churn to keep the common case with no
arguments as meaning guest-triggered, and only modified the
host-triggered code paths, via a wrapper function, but then we'd
still have to audit that I didn't miss any host-triggered spots;
changing the signature forces us to double-check that I correctly
categorized all callers.

Since command line options can change whether a guest reset request
causes an actual reset vs. a shutdown, it's easy to also add the
information to reset requests.

e90f2a8c3e qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.

When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.

Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.

Except for code comments, changes were generated using the
following Coccinelle patch:

2222e0a633 input: Add trace event for empty keyboard queue
When driving QEMU from the outside, we have basically no chance to
determine how quickly the guest OS picks up key events, so we usually
have to limit ourselves to very slow keyboard presses to make sure
the guest always has enough chance to pick them up.

This patch adds a trace events when the keyboarde queue is drained.
An external driver can use that as hint that new keys can be pressed.

57094547df virtio-input: fix eventq batching
virtio_input_send buffers input events until it sees a SYNC. Then it
either sends or drops the entire batch, depending on whether eventq
has enough space available. The case to avoid here is partial sends
where only part of the batch would get to the guest.

Using virtqueue_get_avail_bytes to check the state of eventq was not
correct. The queue may have a smaller number of larger buffers
available so bytes may be enough but the batch would still not be
possible to send, leading to the "Huh?  No vq elem available" error.

Instead of checking available bytes, this patch optimistically pops
buffers from the queue and puts them back in case it runs out of
space and the batch needs to be dropped.

d307c28ca9 i2c: Allow I2C devices to NAK start events
Add a return value to the event handler.  Some I2C devices will
NAK if they have no data, so allow them to do this.  This required
the following changes:

Go through all the event handlers and change them to return int
and return 0.

Modify i2c_start_transfer to terminate the transaction on a NAK.

Modify smbus handing to not assert if a NAK occurs on a second
operation, and terminate the transaction and return -1 instead.

Add some information on semantics to I2CSlaveClass.

86f3bf0ebe hw/input/hid: support alternative sysrq/break scancodes for gtk-vnc
The printscreen/sysrq and pause/break keys currently don't work for guests
using -usbdevice keyboard when accessed through vnc with a gtk-vnc based
client.

The reason for this is a mismatch between gtk-vnc and qemu in how these keys
should be mapped to XT keycodes.

On the original IBM XT these keys behaved differently than other keys.

Quoting from https://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html:

The keys PrtSc/SysRq and Pause/Break are special. The former produces
scancode e0 2a e0 37 when no modifier key is pressed simultaneously, e0 37
together with Shift or Ctrl, but 54 together with (left or right) Alt.  (And
one gets the expected sequences upon release.  But see below.) The latter
produces scancode sequence e1 1d 45 e1 9d c5 when pressed (without modifier)
and nothing at all upon release.  However, together with (left or right)
Ctrl, one gets e0 46 e0 c6, and again nothing at release.  It does not
repeat.

Gtk-vnc supports the 'QEMU Extended Key Event Message' RFB extension to send
raw XT keycodes directly to qemu, but the specification doesn't explicitly
specify how to map such long/complicated keycode sequences.  From the spec
(https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#qemu-extended-key-event-message)

The keycode is the XT keycode that produced the keysym. An XT keycode is an
XT make scancode sequence encoded to fit in a single U32 quantity.  Single
byte XT scancodes with a byte value less than 0x7f are encoded as is.
2-byte XT scancodes whose first byte is 0xe0 and second byte is less than
0x7f are encoded with the high bit of the first byte set

hid.c currently expects the keycode sequence with shift/ctl for sysrq (e0 37
-> 0xb7 in RFB), whereas gtk-vnc uses the sequence with alt (0x54).
Likewise, hid.c expects the code without modifiers (e1 1d 45 -> 0xc5 in
RFB), whereas gtk-vnc sends the keycode sequence with ctrl for pause (e0 46
-> 0xc6 in RFB).

See keymaps.cvs in gtk-vnc for the mapping used:
https://git.gnome.org/browse/gtk-vnc/tree/src/keymaps.csv#n150

Now, it isn't obvious to me which sequence is really "right", but as the
0x54/0xc6 keycodes are currently unused in hid.c, supporting both seems like
the pragmatic solution to me.  The USB HID keyboard boot protocol used by
hid.c doesn't have any other mapping applicable to these keys.

The other guest keyboard interfaces (ps/2, virtio, ..) are not affected,
because they handle these keys differently.

da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

32bafa8fdd qapi: Don't special-case simple union wrappers
Simple unions were carrying a special case that hid their 'data'
QMP member from the resulting C struct, via the hack method
QAPISchemaObjectTypeVariant.simple_union_type().  But by using
the work we started by unboxing flat union and alternate
branches, coupled with the ability to visit the members of an
implicit type, we can now expose the simple union's implicit
type in qapi-types.h:

| struct q_obj_ImageInfoSpecificQCow2_wrapper {
|     ImageInfoSpecificQCow2 *data;
| };
|
| struct q_obj_ImageInfoSpecificVmdk_wrapper {
|     ImageInfoSpecificVmdk *data;
| };
...
| struct ImageInfoSpecific {
|     ImageInfoSpecificKind type;
|     union { /* union tag is @type */
|         void *data;
|-        ImageInfoSpecificQCow2 *qcow2;
|-        ImageInfoSpecificVmdk *vmdk;
|+        q_obj_ImageInfoSpecificQCow2_wrapper qcow2;
|+        q_obj_ImageInfoSpecificVmdk_wrapper vmdk;
|     } u;
| };

Doing this removes asymmetry between QAPI's QMP side and its
C side (both sides now expose 'data'), and means that the
treatment of a simple union as sugar for a flat union is now
equivalent in both languages (previously the two approaches used
a different layer of dereferencing, where the simple union could
be converted to a flat union with equivalent C layout but
different {} on the wire, or to an equivalent QMP wire form
but with different C representation).  Using the implicit type
also lets us get rid of the simple_union_type() hack.

Of course, now all clients of simple unions have to adjust from
using su->u.member to using su->u.member.data; while this touches
a number of files in the tree, some earlier cleanup patches
helped minimize the change to the initialization of a temporary

b5a1b44318 ui: Shorten references into InputEvent
An upcoming patch will alter how simple unions, like InputEvent, are
laid out, which will impact all lines of the form 'evt->u.XXX'
(expanding it to the longer 'evt->u.XXX.data').  For better
legibility in that patch, and less need for line wrapping, it's better
to use a temporary variable to reduce the effect of a layout change to
just the variable initializations, rather than every reference within
an InputEvent.

There was one instance in hid.c:hid_pointer_event() where the code
was referring to evt->u.rel inside the case label where evt->u.abs
is the correct name; thankfully, both members of the union have the
same type, so it happened to work, but it is now cleaner.

51b19ebe43 virtio: move allocation to virtqueue_pop/vring_pop
The return code of virtqueue_pop/vring_pop is unused except to check for
errors or 0.  We can thus easily move allocation inside the functions
and just return a pointer to the VirtQueueElement.

The advantage is that we will be able to allocate only the space that
is needed for the actual size of the s/g list instead of the full
VIRTQUEUE_MAX_SIZE items.  Currently VirtQueueElement takes about 48K
of memory, and this kind of allocation puts a lot of stress on malloc.
By cutting the size by two or three orders of magnitude, malloc can
use much more efficient algorithms.

The patch is pretty large, but changes to each device are testable
more or less independently.  Splitting it would mostly add churn.

d20a580bc0 qapi: Change munging of CamelCase enum values
When munging enum values, the fact that we were passing the entire
prefix + value through camel_to_upper() meant that enum values
spelled with CamelCase could be turned into CAMEL_CASE.  However,
this provides a potential collision (both OneTwo and One-Two would
munge into ONE_TWO) for enum types, when the same two names are
valid side-by-side as QAPI member names.  By changing the generation
of enum constants to always be prefix + '_' + c_name(value,
False).upper(), and ensuring that there are no case collisions (in
the next patches), we no longer have to worry about names that
would be distinct as QAPI members but collide as variant tag names,
without having to think about what munging the heuristics in
camel_to_upper() will actually perform on an enum value.

Making the change will affect enums that did not follow coding
conventions, using 'CamelCase' rather than desired 'lower-case'.

Thankfully, there are only two culprits: InputButton and ErrorClass.
We already tweaked ErrorClass to make it an alias of QapiErrorClass,
where only the alias needs changing rather than the whole tree.  So
the bulk of this change is modifying INPUT_BUTTON_WHEEL_UP to the
new INPUT_BUTTON_WHEELUP (and likewise for WHEELDOWN).  That part
of this commit may later need reverting if we rename the enum
constants from 'WheelUp' to 'wheel-up' as part of moving
x-input-send-event to a stable interface; but at least we have
documentation bread crumbs in place to remind us (commit 513e7cd),
and it matches the fact that SDL constants are also spelled
SDL_BUTTON_WHEELUP.

7fb1cf1606 qapi: Don't let implicit enum MAX member collide
Now that we guarantee the user doesn't have any enum values
beginning with a single underscore, we can use that for our
own purposes.  Renaming ENUM_MAX to ENUM__MAX makes it obvious
that the sentinel is generated.

This patch was mostly generated by applying a temporary patch:

|diff --git a/scripts/qapi.py b/scripts/qapi.py
|index e6d014b..b862ec9 100644
|--- a/scripts/qapi.py
|+++ b/scripts/qapi.py
|@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = {
|     max_index = c_enum_const(name, 'MAX', prefix)
|     ret += mcgen('''
|     [%(max_index)s] = NULL,
|+// %(max_index)s
| };
| ''',
|                max_index=max_index)

then running:

$ cat qapi-{types,event}.c tests/test-qapi-types.c |
    sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list
$ git grep -l _MAX | xargs sed -i -f list

The only things not generated are the changes in scripts/qapi.py.

Rejecting enum members named 'MAX' is now useless, and will be dropped
in the next patch.

568c73a478 input: Convert to new qapi union layout
We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.

Make the conversion to the new layout for input-related code.

"virtio-keyboard-pci", "virtio-mouse-pci", "virtio-tablet-pci" and

"virtio-mouse-device", "virtio-tablet-device" regardless of
CONFIG_LINUX, and compile "virtio-input-host-pci" only for

f8ed85ac99 Fix bad error handling after memory_region_init_ram()
Symptom:

    $ qemu-system-x86_64 -m 10000000
    Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
    upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
    Aborted (core dumped)

Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions.  Before the commit, we report the error and exit(1), in
one place, ram_block_add().  The commit lifts the error handling up
the call chain some, to three places.  Fine.  Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".

The three places are:

* memory_region_init_ram()

  Commit 4994653 (right after commit ef701d7) lifted the error
  handling further, through memory_region_init_ram(), multiplying the
  incorrect use of &error_abort.  Later on, imitation of existing
  (bad) code may have created more.

* memory_region_init_ram_ptr()

  The &error_abort is still there.

* memory_region_init_rom_device()

  Doesn't need fixing, because commit 33e0eb5 (soon after commit
  ef701d7) lifted the error handling further, and in the process
  changed it from &error_abort to passing it up the call chain.
  Correct, because the callers are realize() methods.

Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:

    @r@
    expression mr, owner, name, size, err;
    position p;
    @@
            memory_region_init_ram(mr, owner, name, size,
    (
    -                              &error_abort
    +                              &error_fatal
    |
                                   err@p
    )
                                  );
    @script:python@
        p << r.p;
    @@
    print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)

When the last argument is &error_abort, it gets replaced by
&error_fatal.  This is the fix.

If the last argument is anything else, its position is reported.  This
lets us check the fix is complete.  Four positions get reported:

* ram_backend_memory_alloc()

  Error is passed up the call chain, ultimately through
  user_creatable_complete().  As far as I can tell, it's callers all
  handle the error sanely.

* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()

  DeviceClass.realize() methods, errors handled sanely further up the
  call chain.

We're good.  Test case again behaves:

    $ qemu-system-x86_64 -m 10000000
    qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory
    [Exit 1 ]

The next commits will repair the rest of commit ef701d7's damage.

55a1d80a41 virtio-input: emulated devices [device]
This patch adds the virtio-input-hid base class and
virtio-{keyboard,mouse,tablet} subclasses building on the base class.
They are hooked up to the qemu input core and deliver input events
to the guest like all other hid devices (ps/2 kbd, usb tablet, ...).

Using them is as simple as adding "-device virtio-tablet-device" to
your command line, for use all transports except pci.  virtio-pci
support comes as separate patch, once virtio-pci got virtio 1.0
support.

f73ddbad39 virtio-input: core code & base class [device]
This patch adds virtio-input support to qemu.  It brings a abstract
base class providing core support, other classes can build on it to
actually implement input devices.

virtio-input basically sends linux input layer events (evdev) over
virtio.

The parent ADBDevice contains the device id on the ADB bus. Make sure that
this state is included in both its subclasses since some clients (such as
OpenBIOS) reprogram each device id after enumeration.

0ee4de5840 hw/input/hid.c Fix capslock hid code
When ever USB keyboard is used, e.g. '-usbdevice keyboard' pressing
caps lock key send 0x32 hid code, which is treated as backslash.
Instead it should be 0x39 code. This affects sending uppercase keys,
as they typed whith caps lock active.

While on x86 this can be workarounded by using ps/2 protocol. On
Power it is crusial as we don't have anything else than USB.

This is fixes guest automation tasts over vnc.

d13c040409 pckbd: set bits 2-3-6-7 of the output port by default
OSes typically write 0xdd/0xdf to turn the A20 line off and on.  This
has bits 2-3-6-7 on, so that the output port subsection is migrated.
Change the reset value and migration default to include those four
bits, thus avoiding that the subsection is migrated.

This strictly speaking changes guest ABI, but the long time during which
we have not migrated the value means that the guests really do not care
much; so the change is for all machine types.
