62a35aaa31 qapi: Use returned bool to check for failure, Coccinelle part
The previous commit enables conversion of

    visit_foo(..., &err);
    if (err) {
        ...
    }

to

    if (!visit_foo(..., errp)) {
        ...
    }

for visitor functions that now return true / false on success / error.

0a15a73236 macio: Tidy up error handling in macio_newworld_realize()
macio_newworld_realize() effectively ignores ns->gpio realization
errors, leaking the Error object.  Fortunately, macio_gpio_realize()
can't actually fail.  Tidy up.

Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by
ARMSSE being used both as typedef and function-like macro there.

3029681235 hw/misc/max111x: Create header file for documentation, TYPE_ macros
Create a header file for the hw/misc/max111x device, in the
usual modern style for QOM devices:
 * definition of the TYPE_ constants and macros
 * definition of the device's state struct so that it can
   be embedded in other structs if desired
 * documentation of the interface

This allows us to use TYPE_MAX_1111 in the spitz.c code rather
than the string "max1111".

871f82722c hw/misc/max111x: Use GPIO lines rather than max111x_set_input()
The max111x ADC device model allows other code to set the level on
the 8 ADC inputs using the max111x_set_input() function.  Replace
this with generic qdev GPIO inputs, which also allow inputs to be set
to arbitrary values.

Using GPIO lines will make it easier for board code to wire things
up, so that if device A wants to set the ADC input it doesn't need to
have a direct pointer to the max111x but can just set that value on
its output GPIO, which is then wired up by the board to the
appropriate max111x input.

40d9d2f768 hw/misc/max111x: Don't use vmstate_register()
The max111x is a proper qdev device; we can use dc->vmsd rather than
directly calling vmstate_register().

It's possible that this is a migration compat break, but the only
boards that use this device are the spitz-family ('akita', 'borzoi',
'spitz', 'terrier').

b064d51f60 hw/misc/max111x: provide QOM properties for setting initial values
Add some QOM properties to the max111x ADC device to allow the
initial values to be configured. Currently this is done by
board code calling max111x_set_input() after it creates the
device, which doesn't work on system reset.

This requires us to implement a reset method for this device,
so while we're doing that make sure we reset the other parts
of the device state.

2726dc51e0 hw: Fix error API violation around object_property_set_link()
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.

virtio_gpu_pci_base_realize(), virtio_vga_base_realize(),
sparc32_ledma_device_realize(), sparc32_dma_realize(),
sparc32_dma_realize() xilinx_axidma_realize(), mips_cps_realize(),
macio_realize_ide(), xilinx_enet_realize(), and
virtio_iommu_pci_realize() are wrong that way: they reuse the argument
they pass to object_property_set_link() for another call.

Harmless, because object_property_set_link() can't actually fail for
them: it fails when the property doesn't exist, is not settable, or
its .check() method fails.  Fix by passing &error_abort instead.

output or PWM mode. QEMU models the output GPIO with
the qemu_irq type. Let the device expose the 16 GPIOs
to allow us to later connect LEDs to these outputs.

913f47ef96 adb: only call autopoll callbacks when autopoll is not blocked
Handle this at the ADB bus level so that individual implementations do not need
to handle this themselves.

Finally add an assert() into adb_request() to prevent developers from accidentally
making an explicit ADB request without blocking autopoll.

975fcedd31 mac_via: rework ADB state machine to be compatible with both MacOS and Linux
The existing ADB state machine is designed to work with Linux which has a different
interpretation of the state machine detailed in "Guide to the Macintosh Family
Hardware". In particular the current Linux implementation includes an extra change
to IDLE state when switching the VIA between send and receive modes which does not
occur in MacOS, and omitting this transition causes the current mac_via ADB state
machine to fail.

Rework the ADB state machine accordingly so that it can enumerate and autopoll the
ADB under both Linux and MacOS, including the addition of the new adb_autopoll_block()
and adb_autopoll_unblock() functions.

db873cc5d1 sysbus: Convert qdev_set_parent_bus() use with Coccinelle, part 2
This is the same transformation as in the previous commit, except
sysbus_init_child_obj() and realize are too separated for the commit's
Coccinelle script to handle, typically because sysbus_init_child_obj()
is in a device's instance_init() method, and the matching realize is
in its realize() method.

Perhaps a Coccinelle wizard could make it transform that pattern, but
I'm just a bungler, and the best I can do is transforming the two
separate parts separately:

This script is *unsound*: we need to manually verify init and realize
conversions are properly paired.

This commit has only the pairs where object_initialize_child()'s
@child and sysbus_realize()'s @dev argument text match exactly within
the same source file.

Note that Coccinelle chokes on ARMSSE typedef vs. macro in
hw/arm/armsse.c.  Worked around by temporarily renaming the macro for
the spatch run.

0074fce61f sysbus: Convert qdev_set_parent_bus() use with Coccinelle, part 1
I'm converting from qdev_set_parent_bus()/realize to qdev_realize();
recent commit "qdev: Convert uses of qdev_set_parent_bus() with

sysbus_init_child_obj() is a wrapper around
object_initialize_child_with_props() and qdev_set_parent_bus().  It
passes no properties.

Convert sysbus_init_child_obj()/realize to object_initialize_child()/
qdev_realize().

8fb9cfe762 macio: Eliminate macio_init_child_obj()
macio_init_child_obj() has become a trivial wrapper around
object_initialize_child_with_props().  Eliminate it, since the general
convenience wrapper object_initialize_child() is just as convenient
already.

9fc7fc4d39 qom: Less verbose object_initialize_child()
All users of object_initialize_child() pass the obvious child size
argument.  Almost all pass &error_abort and no properties.  Tiresome.

Rename object_initialize_child() to
object_initialize_child_with_props() to free the name.  New
convenience wrapper object_initialize_child() automates the size
argument, and passes &error_abort and no properties.

Rename object_initialize_childv() to
object_initialize_child_with_propsv() for consistency.

Convert callers with this Coccinelle script:

99ba777e53 qdev: Convert uses of qdev_set_parent_bus() with Coccinelle
In addition to the qdev_create() patterns converted so far, we have a
qdev_set_parent_bus() pattern.  Mostly when we embed a device in a
parent device rather than allocating it on the heap.

This pattern also puts devices in the dangerous "no QOM parent, but
plugged into bus" state I explained in recent commit "qdev: New
qdev_new(), qdev_realize(), etc."

Apply same solution: convert to qdev_realize().  Coccinelle script:

    +    qdev_realize(DEVICE(dev), bus, &error_fatal);

Unconverted uses of qdev_set_parent_bus() remain.  They'll be
converted later in this series.

33208432f5 macio: Delete unused "macio-gpio" devices
These devices go with the "via-pmu" device, which is controlled by
property "has-pmu".  macio_newworld_init() creates it unconditionally,
because the property has not been set then.  macio_newworld_realize()
realizes it only when the property is true.  Works, although it can
leave an unrealized device hanging around in the QOM composition tree.

3d81f594fd macio: Fix to realize "mos6522-cuda" and "mos6522-pmu" devices
cuda_init() creates a "mos6522-cuda" device, but it's never realized.
Affects machines mac99 with via=cuda (default) and g3beige.

pmu_init() creates a "mos6522-pmu" device, but it's never realized.
Affects machine mac99 with via=pmu and via=pmu-adb,

In theory, a device becomes real only on realize.  In practice, the
transition from unreal to real is a fuzzy one.  The work to make a
device real can be spread between realize methods (fine),
instance_init methods (wrong), and board code wiring up the device
(fine as long as it effectively happens on realize).  Depending on
what exactly is done where, a device can work even when we neglect
to realize it.

These two appear to work.  Nevertheless, it's a clear misuse of the
interface.  Even when it works today (more or less by chance), it can
break tomorrow.

Fix by realizing them in cuda_realize() and pmu_realize(),
respectively.

1a5a557088 hw/misc/grlib_ahb_apb_pnp: Fix AHB PnP 8-bit accesses
The Plug & Play region of the AHB/APB bridge can be accessed
by various word size, however the implementation is clearly
restricted to 32-bit:

  static uint64_t grlib_ahb_pnp_read(void *opaque, hwaddr offset, unsigned size)
  {
      AHBPnp *ahb_pnp = GRLIB_AHB_PNP(opaque);

      return ahb_pnp->regs[offset >> 2];
  }

Similarly to commit 0fbe394a64 with the APB PnP registers,
set the MemoryRegionOps::impl min/max fields to 32-bit, so
memory.c::access_with_adjusted_size() can adjust when the
access is not 32-bit.

8e5c952b37 hw: Remove unnecessary DEVICE() cast
The DEVICE() macro is defined as:

  #define DEVICE(obj) OBJECT_CHECK(DeviceState, (obj), TYPE_DEVICE)

which expands to:

  ((DeviceState *)object_dynamic_cast_assert((Object *)(obj), (name),
                                             __FILE__, __LINE__,
                                             __func__))

This assertion can only fail when @obj points to something other
than its stated type, i.e. when we're in undefined behavior country.

Remove the unnecessary DEVICE() casts when we already know the
pointer is of DeviceState type.

Patch created mechanically using spatch with this script:

  DeviceState *s;

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().

The allwinner_h3_dramc_map_rows function simulates row addressing behavior
when bootloader software attempts to detect the amount of available SDRAM.

Currently the line that calculates the 64-bit address of the mirrored row
uses a signed 32-bit multiply operation that in theory could result in the
upper 32-bit be all 1s. This commit ensures that the row mirror address
is calculated using only 64-bit operations.

64a7b8de42 qom/object: Use common get/set uint helpers
Several objects implemented their own uint property getters and setters,
despite them being straightforward (without any checks/validations on
the values themselves) and identical across objects. This makes use of
an enhanced API for object_property_add_uintXX_ptr() which offers
default setters.

Some of these setters used to update the value even if the type visit
failed (eg. because the value being set overflowed over the given type).
The new setter introduces a check for these errors, not updating the
value if an error occurred. The error is propagated.

f7795e4096 misc: Replace zero-length arrays with flexible array member (automatic)
Description copied from Linux kernel commit from Gustavo A. R. Silva
(see [3]):

--v-- description start --v--

  The current codebase makes use of the zero-length array language
  extension to the C90 standard, but the preferred mechanism to
  declare variable-length types such as these ones is a flexible
  array member [1], introduced in C99:

  struct foo {
      int stuff;
      struct boo array[];
  };

  By making use of the mechanism above, we will get a compiler
  warning in case the flexible array does not occur last in the
  structure, which will help us prevent some kind of undefined
  behavior bugs from being unadvertenly introduced [2] to the
  Linux codebase from now on.

--^-- description end --^--

Do the similar housekeeping in the QEMU codebase (which uses
C99 since commit 7be41675f7).

All these instances of code were found with the help of the
following Coccinelle script:

ca6155c0f2 Merge tag 'patchew/20200219160953.13771-1-imammedo@redhat.com' of https://github.com/patchew-project/qemu into HEAD
This series removes ad hoc RAM allocation API (memory_region_allocate_system_memory)
and consolidates it around hostmem backend. It allows to

* resolve conflicts between global -mem-prealloc and hostmem's "policy" option,
  fixing premature allocation before binding policy is applied

* simplify complicated memory allocation routines which had to deal with 2 ways
  to allocate RAM.

* reuse hostmem backends of a choice for main RAM without adding extra CLI
  options to duplicate hostmem features.  A recent case was -mem-shared, to
  enable vhost-user on targets that don't support hostmem backends [1] (ex: s390)

* move RAM allocation from individual boards into generic machine code and
  provide them with prepared MemoryRegion.

* clean up deprecated NUMA features which were tied to the old API (see patches)
  - "numa: remove deprecated -mem-path fallback to anonymous RAM"
  - (POSTPONED, waiting on libvirt side) "forbid '-numa node,mem' for 5.0 and newer machine types"
  - (POSTPONED) "numa: remove deprecated implicit RAM distribution between nodes"

Introduce a new machine.memory-backend property and wrapper code that aliases
global -mem-path and -mem-alloc into automatically created hostmem backend
properties (provided memory-backend was not set explicitly given by user).
A bulk of trivial patches then follow to incrementally convert individual
boards to using machine.memory-backend provided MemoryRegion.

Board conversion typically involves:

* providing MachineClass::default_ram_size and MachineClass::default_ram_id
  so generic code could create default backend if user didn't explicitly provide
  memory-backend or -m options

* dropping memory_region_allocate_system_memory() call

* using convenience MachineState::ram MemoryRegion, which points to MemoryRegion
   allocated by ram-memdev

On top of that for some boards:

* missing ram_size checks are added (typically it were boards with fixed ram size)

* ram_size fixups are replaced by checks and hard errors, forcing user to
  provide correct "-m" values instead of ignoring it and continuing running.

After all boards are converted, the old API is removed and memory allocation
routines are cleaned up.

533eb415df arm/aspeed: actually check RAM size
It's supposed that SOC will check if "-m" provided
RAM size is valid by setting "ram-size" property and
then board would read back valid (possibly corrected
value) to map RAM MemoryReging with valid size.
It isn't doing so, since check is called only
indirectly from
  aspeed_sdmc_reset()->asc->compute_conf()
or much later when guest writes to configuration
register.

So depending on "-m" value QEMU end-ups with a warning
and an invalid MemoryRegion size allocated and mapped.
(examples:
 -M ast2500-evb -m 1M
    0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
      0000000080000000-00000000800fffff (prio 0, ram): ram
      0000000080100000-00000000bfffffff (prio 0, i/o): max_ram
 -M ast2500-evb -m 3G
    0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
      0000000080000000-000000013fffffff (prio 0, ram): ram
      [DETECTED OVERFLOW!] 0000000140000000-00000000bfffffff (prio 0, i/o): max_ram
)
On top of that sdmc falls back and reports to guest
"default" size, it thinks machine should have.

This patch makes ram-size check actually work and
changes behavior from a warning later on during
machine reset to error_fatal at the moment SOC.ram-size
is set so user will have to fix RAM size on CLI
to start machine.

It also gets out of the way mutable ram-size logic,
so we could consolidate RAM allocation logic around
pre-allocated hostmem backend (supplied by user or
auto created by generic machine code depending on
supplied -m/mem-path/mem-prealloc options.

068fe58cf9 mos6522: remove anh register
Register addr 1 is defined as buffer A with handshake (vBufAH),
register addr 15 is also defined as buffer A without handshake (vBufA).

As both addresses access the same register, remove the definition of
'anh' and use only 'a' (with VIA_REG_ANH and VIA_REG_A).

eb064db94c q800: add a block backend to the PRAM
This allows to save and restore the content of the PRAM.
It may be useful if we want to check the configuration or to change it.

The backend is added using mtd interface, for instance:

    ... -drive file=pram.img,format=raw,if=mtd ...

where pram.img is the file where the data will be stored, its size must
be 256 bytes.

cd8843ff25 mos6522: fix T1 and T2 timers
With the Quadra 800 emulation, mos6522 timers processing can consume
until 70% of the host CPU time with an idle guest (I guess the problem
should also happen with PowerMac emulation).

On a recent system, it can be painless (except if you look at top), but
on an old host like a PowerMac G5 the guest kernel can be terribly slow
during the boot sequence (for instance, unpacking initramfs can take 15
seconds rather than only 3 seconds).

We can avoid this CPU overload by enabling QEMU internal timers only if
the mos6522 counter interrupts are enabled. Sometime the guest kernel
wants to read the counters values, but we don't need the timers to
update the counters.

With this patch applied, an idle Q800 consumes only 3% of host CPU time
(and the guest can boot in a decent time).

0fbe394a64 hw/misc/grlib_ahb_apb_pnp: Fix 8-bit accesses
The Plug & Play region of the AHB/APB bridge can be accessed
by various word size, however the implementation is clearly
restricted to 32-bit:

  static uint64_t grlib_apb_pnp_read(void *opaque, hwaddr offset, unsigned size)
  {
      APBPnp *apb_pnp = GRLIB_APB_PNP(opaque);

      return apb_pnp->regs[offset >> 2];
  }

Set the MemoryRegionOps::impl min/max fields to 32-bit, so
memory.c::access_with_adjusted_size() can adjust when the
access is not 32-bit.

This is required to run RTEMS on leon3, the grlib scanning
functions do byte accesses.

372a87a1d9 Do not use %m in common code to print error messages
The %m format specifier is an extension from glibc - and when compiling
QEMU for NetBSD, the compiler correctly complains, e.g.:

/home/qemu/qemu-test.ELjfrQ/src/util/main-loop.c: In function 'sigfd_handler':
/home/qemu/qemu-test.ELjfrQ/src/util/main-loop.c:64:13: warning: %m is only
 allowed in syslog(3) like functions [-Wformat=]
             printf("read from sigfd returned %zd: %m\n", len);
             ^
Let's use g_strerror() here instead, which is an easy-to-use wrapper
around the thread-safe strerror_r() function.

While we're at it, also convert the "printf()" in main-loop.c into
the preferred "error_report()".

794dcb54b3 trace: Remove trailing newline in events
While the tracing framework does not forbid trailing newline in
events format string, using them lead to confuse output.
It is the responsibility of the backend to properly end an event

Some of our formats have trailing newlines, remove them.

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.

2f780b6a91 sysemu: Move the VMChangeStateEntry typedef to qemu/typedefs.h

recompile of some 1800 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h, down from 5400 due to the

Several headers include sysemu/sysemu.h just to get typedef
VMChangeStateEntry.  Move it from sysemu/sysemu.h to qemu/typedefs.h.
Spell its structure tag the same while there.  Drop the now
superfluous includes of sysemu/sysemu.h from headers.

Touching sysemu/sysemu.h now recompiles some 1100 objects.
qemu/uuid.h also drops from 1800 to 1100, and
qapi/qapi-types-run-state.h from 5000 to 4400.

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.

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.

db72581598 Include qemu/main-loop.h less
In my "build everything" tree, changing qemu/main-loop.h triggers a
recompile of some 5600 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).  It includes block/aio.h,
which in turn includes qemu/event_notifier.h, qemu/notify.h,
qemu/processor.h, qemu/qsp.h, qemu/queue.h, qemu/thread-posix.h,
qemu/thread.h, qemu/timer.h, and a few more.

Include qemu/main-loop.h only where it's needed.  Touching it now
recompiles only some 1700 objects.  For block/aio.h and
qemu/event_notifier.h, these numbers drop from 5600 to 2800.  For the
others, they shrink only slightly.

954d97672f hw/misc/macio: Use object_initialize_child for correct ref. counting
As explained in commit aff39be0ed:

  Both functions, object_initialize() and object_property_add_child()
  increase the reference counter of the new object, so one of the
  references has to be dropped afterwards to get the reference
  counting right. Otherwise the child object will not be properly
  cleaned up when the parent gets destroyed.
  Thus let's use now object_initialize_child() instead to get the
  reference counting here right.

This patch was generated using the following Coccinelle script
(with a bit of manual fix-up for overly long lines):

 @use_object_initialize_child@
 expression parent_obj;
 expression child_ptr;
 expression child_name;
 expression child_type;
 expression child_size;
 expression errp;
 @@
 (
 -   object_initialize(child_ptr, child_size, child_type);
 +   object_initialize_child(parent_obj, child_name,  child_ptr, child_size,
 +                           child_type, &error_abort, NULL);
     ... when != parent_obj
 -   object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), NULL);
     ...
 ?-  object_unref(OBJECT(child_ptr));
 |
 -   object_initialize(child_ptr, child_size, child_type);
 +   object_initialize_child(parent_obj, child_name,  child_ptr, child_size,
 +                            child_type, errp, NULL);
     ... when != parent_obj
 -   object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), errp);
     ...
 ?-  object_unref(OBJECT(child_ptr));
 )

While the object_initialize() function doesn't take an
'Error *errp' argument, the object_initialize_child() does.
Since this code is used when a machine is created (and is not
yet running), we deliberately choose to use the &error_abort
argument instead of ignoring errors if an object creation failed.

7c28b925b7 build: convert pci.mak to Kconfig
Instead of including the same list of devices for each target,
set CONFIG_PCI to true, and make the devices default to present
whenever PCI is available.  However, s390x does not want all the
PCI devices, so there is a separate symbol to enable them.

Done mostly with the following script:

  while read i; do
     i=${i%=y}; i=${i#CONFIG_}
     sed -i -e'/^config '$i'$/!b' -en \
            -e'a\' -e'    default y if PCI_DEVICES\' -e'    depends on PCI' \
          `grep -lw $i hw/*/Kconfig`
  done < default-configs/pci.mak

followed by replacing a few "depends on" clauses with "select"
whenever the symbol is not really related to PCI.

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.

82f5181777 kconfig: introduce kconfig files
The Kconfig files were generated mostly with this script:

  for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* | sort -u`; do
    set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' `
    shift

EOF
      git add $(dirname $1)/Kconfig
    else
      echo $i $*
    fi
  done
  sed -i '$d' hw/*/Kconfig

    if test -d $i && ! test -f $i/Kconfig; then
      touch $i/Kconfig
      git add $i/Kconfig
    fi
  done

Whenever a symbol is referenced from multiple subdirectories, the
script prints the list of directories that reference the symbol.
These symbols have to be added manually to the Kconfig files.

Kconfig.host and hw/Kconfig were created manually.

aab7a3786f hw/arm/armsse: Unify init-svtor and cpuwait handling
At the moment the handling of init-svtor and cpuwait initial
values is split between armsse.c and iotkit-sysctl.c:
the code in armsse.c sets the initial state of the CPU
object by setting the init-svtor and start-powered-off
properties, but the iotkit-sysctl.c code has its own
code setting the reset values of its registers (which are
then used when updating the CPU when the guest makes
runtime changes).

Clean this up by making the armsse.c code set properties on the
iotkit-sysctl object to define the initial values of the
registers, so they always match the initial CPU state,
and update the comments in armsse.c accordingly.

0f862986e0 hw/arm/iotkit-sysctl: Implement CPUWAIT and INITSVTOR*
The CPUWAIT register acts as a sort of power-control: if a bit
in it is 1 then the CPU will have been forced into waiting
when the system was reset (which in QEMU we model as the
CPU starting powered off). Writing a 0 to the register will
allow the CPU to boot (for QEMU, we model this as powering
it on). Note that writing 0 to the register does not power
off a CPU.

For this to work correctly we need to also honour the
INITSVTOR* registers, which let the guest control where the
CPU will load its SP and PC from when it comes out of reset.

37e571f1e0 hw/misc/tz-ppc: Support having unused ports in the middle of the range
The Peripheral Protection Controller's handling of unused ports
is that if there is nothing connected to the port's downstream
then it does not create the sysbus MMIO region for the upstream
end of the port. This results in odd behaviour when there is
an unused port in the middle of the range: since sysbus MMIO
regions are implicitly consecutively allocated, any used ports
above the unused ones end up with sysbus MMIO region numbers
that don't match the port number.

Avoid this numbering mismatch by creating dummy MMIO regions
for the unused ports. This doesn't change anything for our
existing boards, which don't have any gaps in the middle of
the port ranges they use; but it will be needed for the Musca
board.

d6c666ad81 cuda: decrease time delay before raising VIA SR interrupt and remove fast path
In order to handle a race condition in the MacOS 9 CUDA driver, a
delay was introduced when raising the VIA SR interrupt inspired by
similar code in MacOnLinux.

During original testing of the MacOS 9 patches it was found that the
30us delay used in MacOnLinux did not work reliably within QEMU, and a
value of 300us was required to function correctly.

Recent experiments have shown two things: firstly when booting Linux,
MacOS 9 and MacOS X the fast path which bypasses the delay is never
triggered once the OS kernel is loaded making it effectively
useless. Rather than leave this code in place where a guest could
potentially enable it by accident and break itself, we might as well
just remove it.

Secondly the previous reliability issues are no longer present, and
this value can be reduced down to 20us with no apparent ill
effects. This has the benefit of considerably improving the
responsiveness of the ADB keyboard and mouse within the guest.

5a0e75f0a9 hw/misc/ivshmem: Remove deprecated "ivshmem" legacy device
It's been marked as deprecated in QEMU v2.6.0 already, so really nobody
should use the legacy "ivshmem" device anymore (but use ivshmem-plain or
ivshmem-doorbell instead). Time to remove the deprecated device now.

Belatedly also update a mention of the deprecated "ivshmem" in the file
docs/specs/ivshmem-spec.txt to "ivshmem-doorbell". Missed in commit
5400c02b90 ("ivshmem: Split ivshmem-plain, ivshmem-doorbell off ivshmem").

7d37435bd5 avoid TABs in files that only contain a few
Most files that have TABs only contain a handful of them.  Change
them to spaces so that we don't confuse people.

disas, standard-headers, linux-headers and libdecnumber are imported
from other projects and probably should be exempted from the check.
Outside those, after this patch the following files still contain both
8-space and TAB sequences at the beginning of the line.  Many of them
have a majority of TABs, or were initially committed with all tabs.

619d54a8d8 hw/misc/tz-mpc: Fix value of BLK_MAX register
In the TZ Memory Protection Controller, the BLK_MAX register is supposed
to return the maximum permitted value of the BLK_IDX register. Our
implementation incorrectly returned max+1 (ie the total number of
valid index values, since BLK_IDX is zero-based).

Correct this off-by-one error. Since we consistently initialize
and use s->blk_max throughout the implementation as the 'size'
of the LUT, just adjust the value we return when the guest reads
the BLK_MAX register, rather than trying to change the semantics
of the s->blk_max internal struct field.

access functions. Rename it to address_space_write_rom(), and

3650b2de34 qom: make user_creatable_complete() specific to UserCreatable
Instead of accepting any Object*, change user_creatable_complete() to
require a UserCreatable*. Modify the callers to pass the appropriate
argument, removing redundant dynamic cast checks in object creation.

3381466dc9 misc: Avoid UTF-8 in error messages
While most developers are now using UTF-8 environments, it's
harder to guarantee that error messages will be output to
a multibyte locale. Rather than risking error messages that
get corrupted into mojibake when the user runs qemu in a
non-multibyte locale, let's stick to straight ASCII error
messages, rather than assuming that our use of UTF-8 in source
code string constants will work unchanged in other locales.

When you clone the repository without previous commit history, 'git://'
doesn't protect from man-in-the-middle attacks.  HTTPS is more secure

bce410a33b ivshmem: fix memory backend leak
object_new() returns a new backend with refcount == 1 and
then later object_property_add_child() increases refcount to 2
So when ivshmem is destroyed, the backend it has created isn't
destroyed along with it as children cleanup will bring
backend's refcount only to 1, which leaks backend including
resources it is using.

Drop the original reference from object_new() once backend
is attached to its parent.

1ba5c3a954 hyperv_testdev: refactor for better maintainability
Make hyperv_testdev slightly easier to follow and enhance in future.
For that, put the hyperv sint routes (wrapped in a helper structure) on
a linked list rather than a fixed-size array.  Besides, this way
HvSintRoute can be treated as an opaque structure, allowing for easier
refactoring of the core Hyper-V SynIC code in followup pathches.

b266f1d112 ivshmem: Fix unplug of device "ivshmem-plain"
Commit 2aece63c8a "hostmem: detect host backend memory is being used
properly" fixed "ivshmem-plain" to reject memory backends that are
already in use, and to block their deletion while in use.  Two bugs
escaped review:

* New ivshmem_plain_exit() fails to call ivshmem_exit().  This breaks
  unplug.  Reproducer: migration after unplug still fails with
  "Migration is disabled when using feature 'peer mode' in device
  'ivshmem'".

* It failed to update legacy "ivshmem".  Harmless, because it creates
  the memory backend itself, and nothing else should use it.

Fix by moving the two host_memory_backend_set_mapped() calls into
ivshmem_common_realize() and ivshmem_exit(), guarded by s->hostmem.

As the in-built IDE controller is attached to the macio bus then we should also
model this the same in QEMU to aid fw path generation.

Note that all existing macio devices are moved onto the new macio bus so that
the qdev tree accurately reflects the real hardware.

f8add62c0c hw/display/bcm2835_fb: Validate config settings
Validate the config settings that the guest tries to set.

The wiki page documentation is not really accurate here:
generally rather than failing requests to set bad parameters,
the hardware will just clip them to something sensible.

Validate the most important parameters: sizes and
the viewport offsets. This prevents the framebuffer
code from trying to read out-of-range memory.

In the property handling code, we validate the new parameters every
time we encounter a tag that sets them. This means we validate the
config multiple times if the request includes multiple config-setting
tags, but the code would require significant restructuring to do a
validation only once but still return the clipped settings for
get-parameter tags and the buffer allocation tag.

Validation of settings made via the older bcm2835_fb_mbox_push()
function will be done in the next commit.

01f18af98b hw/display/bcm2835_fb: Fix handling of virtual framebuffer
The raspi framebuffir in bcm2835_fb supports the definition
of a virtual "viewport", which is smaller than the full
physical framebuffer size and at an adjustable offset within
it. Only the viewport area is sent to the screen. This allows
the guest to do things like double buffering, or scrolling
by adjusting the viewport origin. Currently QEMU doesn't
implement this at all.

Add support for this feature:
 * the property mailbox code needs to distinguish the
   virtual width/height from the physical width/height
 * the framebuffer code needs to do something with the
   virtual width/height/origin information

Note that the wiki documentation on the semantics of the
virtual and physical height and width has it the wrong way
around -- the virtual size is the size of the allocated
buffer, and the physical size is the size of the display,
so the virtual size is always the same as or larger than
the physical.

If the viewport size is set smaller than the physical
screen size, we ignore the viewport settings completely
and just display the physical screen area.

193100b571 hw/misc/bcm2835_property: Track fb settings using BCM2835FBConfig
Refactor the fb property setting code so that rather than
using a set of pointers to local variables to track
whether a config value has been updated in the current
mbox and if so what its new value is, we just copy
all the current settings of the fb at the start, and
then update that copy as we go along, before asking
the fb to switch to it at the end.

a02755ece0 hw/misc/bcm2835_fb: Move config fields to their own struct
The handling of framebuffer properties in the bcm2835_property code
is a bit clumsy, because for each of the many fb related properties
we try to track the value we're about to set and whether we're going
to be setting a value, and then we hand all the new values off
to the framebuffer via a function which takes them all as separate
arguments. It would be simpler if the property code could easily
copy all the framebuffer's current settings, update them with
the new specified values and then ask the framebuffer to switch
to the new set.

As the first part of this refactoring, pull all the fb config
settings fields in BCM2835FBState out into their own struct.

218fe5ce40 hw/misc/tz-mpc: Zero the LUT on initialization, not just reset
In the tz-mpc device we allocate a data block for the LUT,
which we then clear to zero in the device's reset method.
This is conceptually fine, but unfortunately results in a

==30906==    by 0x7B1775: qemu_devices_reset (reset.c:69)

This is because of a reset ordering problem -- the TZ MPC
resets after the CPU, but an M-profile CPU's reset function
includes memory loads to get the initial PC and SP, which
then go through an MPC that hasn't yet been reset.

The simplest fix for this is to zero the LUT when we
initialize the data, which will result in the MPC's
translate function giving the right answers for these
early memory accesses.

the corresponding object. This is unlike qdev_create(), and it is wrong
because qdev_init_nofail() must not be called from an instance_init
function.  Move qdev_init_nofail() and the subsequent aux_map_slave into
the caller's realize function.

There are two more bugs that needs to be fixed here, too, where the
objects are created but not added as children.  Therefore when
you call object_unparent on them, nothing happens.

In particular dpcd and edid give you an infinite loop in bus_unparent,
because device_unparent is not called and does not remove them from
the list of devices on the bus.

333b9c8a68 aspeed: Implement write-1-{set, clear} for AST2500 strapping
The AST2500 SoC family changes the runtime behaviour of the hardware
strapping register (SCU70) to write-1-set/write-1-clear, with
write-1-clear implemented on the "read-only" SoC revision register
(SCU7C). For the the AST2400, the hardware strapping is
runtime-configured with read-modify-write semantics.

1b2013ea5d hyperv: rename vcpu_id to vp_index
In Hyper-V-related code, vCPUs are identified by their VP (virtual
processor) index.  Since it's customary for "vcpu_id" in QEMU to mean
APIC id, rename the respective variables to "vp_index" to make the
distinction clear.

Here's a last minue pull request before today's soft freeze.  Ideally
 I would have sent this earlier, but I was waiting for a couple of
 extra fixes I knew were close.  And the freeze crept up on me, like
 always.
 
 Most of the changes here are bugfixes in any case.  There are some
 cleanups as well, which have been in my staging tree for a little
 while.  There are a couple of truly new features (some extensions to
 the sam460ex platform), but these are low risk, since they only affect
 a new and not really stabilized machine type anyway.
 
 Higlights are:
   * Mac platform improvements from Mark Cave-Ayland
   * Sam460ex improvements from BALATON Zoltan et al.
   * XICS interrupt handler cleanups from Cédric Le Goater
   * TCG improvements for atomic loads and stores from Richard
     Henderson
   * Assorted other bugfixes
