Thomas Huth 3858ff7639 hw/core: Move null-machine into the common-obj list
The null-machine code used to be target specific since it used the
target-specific cpu_init() function in the past. But in the recent
commit 2278b93941 ("Use cpu_create(type) instead of
cpu_init(cpu_model)") this has been change, so that the code now
uses the common cpu_create() function instead. Thus we can put
the null-machine into the common-obj list so that it is compiled
only once for all targets, to save some compilation time.

Igor Mammedov 8b5e6caf01 call HotplugHandler->plug() as the last step in device realization
When [2] was fixed it was agreed that adding and calling post_plug()
callback after device_reset() was low risk approach to hotfix issue
right before release. So it was merged instead of moving already
existing plug() callback after device_reset() is called which would
be more risky and require all plug() callbacks audit.

Looking at the current plug() callbacks, it doesn't seem that moving
plug() callback after device_reset() is breaking anything, so here
goes agreed upon [3] proper fix which essentially reverts [1][2]
and moves plug() callback after device_reset().
This way devices always comes to plug() stage, after it's been fully
initialized (including being reset), which fixes race condition [2]
without need for an extra post_plug() callback.

The generated qapi_event_send_FOO() take an Error ** argument.  They
can't actually fail, because all they do with the argument is passing it

Drop the argument, and pass &error_abort to the QObject output visitor

Mark Cave-Ayland be64d7776b sysbus: always allow explicit_ofw_unit_address() to override address generation
Some SysBusDevices either use sysbus_init_mmio() without
sysbus_mmio_map() or the first MMIO memory region doesn't represent the
bus address, causing a firmware device path with an invalid address to
be generated.

SysBusDeviceClass does provide a virtual explicit_ofw_unit_address()
method that can be used to override this process, but it was originally intended
only as as a fallback option meaning that any existing MMIO memory regions still
take priority whilst determining the firmware device address.

There is currently only one user of explicit_ofw_unit_address() and that
is the PCI expander bridge (PXB) device which has no MMIO/PIO resources
defined. This enables us to allow explicit_ofw_unit_address() to take
priority without affecting backwards compatibility, allowing the address
to be customised as required.

Su Hang e4a25ed919 loader: Implement .hex file loader
This patch adds Intel Hexadecimal Object File format support to the
generic loader device.  The file format specification is available here:
http://www.piclist.com/techref/fileext/hex/intel.htm

This file format is often used with microcontrollers such as the
micro:bit, Arduino, STM32, etc.  Users expect to be able to run .hex
files directly with without first converting them to ELF.  Most
micro:bit code is developed in web-based IDEs without direct user access
to binutils so it is important for QEMU to handle this file format
natively.

through loading there is no easy way to drop previously added roms.

This patch adds a transaction mechanism that works like this:

  rom_transaction_begin();
  ...call rom_add_*()...
  rom_transaction_end(ok);

Stefan Hajnoczi e7f5993354 loader: extract rom_free() function
The next patch will need to free a rom.  There is already code to do
this in rom_add_file().

Note that rom_add_file() uses:

  rom = g_malloc0(sizeof(*rom));
  ...
  if (rom->fw_dir) {
      g_free(rom->fw_dir);
      g_free(rom->fw_file);
  }

The conditional is unnecessary since g_free(NULL) is a no-op.

The machine_run_board_init() doesn't do NUMA setup if nb_numa_nodes=0,

is enabled (slots > 0) even nb_numa_nodes=0.

So, Remove the check for numa_complete_configuration() to fix this.

Thomas Huth 0f0f8b611e loader: Check access size when calling rom_ptr() to avoid crashes
The rom_ptr() function allows direct access to the ROM blobs that we
load during startup. However, there are currently no checks for the
size of the accesses, so it's currently possible to crash QEMU for
example with:

$ echo "Insane in the mainframe" > /tmp/test.txt
$ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -append xyz
Segmentation fault (core dumped)
$ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -initrd /tmp/test.txt
Segmentation fault (core dumped)
$ echo -n HdrS > /tmp/hdr.txt
$ sparc64-softmmu/qemu-system-sparc64 -kernel /tmp/hdr.txt -initrd /tmp/hdr.txt
Segmentation fault (core dumped)

We need a possibility to check the size of the ROM area that we want
to access, thus let's add a size parameter to the rom_ptr() function
to avoid these problems.

Peter Maydell f81804a52b hw/core/or-irq: Support more than 16 inputs to an OR gate
For the IoTKit MPC support, we need to wire together the
interrupt outputs of 17 MPCs; this exceeds the current
value of MAX_OR_LINES. Increase MAX_OR_LINES to 32 (which
should be enough for anyone).

The tricky part is retaining the migration compatibility for
existing OR gates; we add a subsection which is only used
for larger OR gates, and define it such that we can freely
increase MAX_OR_LINES in future (or even move to a dynamically
allocated levels[] array without an upper size limit) without
breaking compatibility.

Marc-André Lureau 265b578c58 object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalence
A link property can be set during creation, with
object_property_add_link() and later with object_property_set_link().

add_link() doesn't add a reference to the target object, while
set_link() does.

Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.
This can lead to leaks if the property was later set_link(), as the
added reference is never released.

Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG
and use that has an indication on how the link handle reference
management in set_link().

It's been marked as deprecated since QEMU v2.9.0, so that should have
been enough time for everybody to either just drop unnecessary "vlan=0"
parameters, to switch to the modern -device + -netdev syntax for connecting
guest NICs with host network backends, or to switch to the "hubport" netdev
in case hubs are really wanted instead.

Igor Mammedov a3fc839635 platform-bus-device: use device plug callback instead of machine_done notifier
platform-bus were using machine_done notifier to get and map
(assign irq/mmio resources) dynamically added sysbus devices
after all '-device' options had been processed.
That however creates non obvious dependencies on ordering of
machine_done notifiers and requires carefull line juggling
to keep it working. For example see comment above
create_platform_bus() and 'straitforward' arm_load_kernel()
had to converted to machine_done notifier and that lead to
yet another machine_done notifier to keep it working
arm_register_platform_bus_fdt_creator().

Instead of hiding resource assignment in platform-bus-device
to magically initialize sysbus devices, use device plug
callback and assign resources explicitly at board level
at the moment each -device option is being processed.

That adds a bunch of machine declaration boiler plate to
e500plat board, similar to ARM/x86 but gets rid of hidden
machine_done notifier and would allow to remove the dependent
notifiers in ARM code simplifying it and making code flow
easier to follow.

Igor Mammedov 2278b93941 Use cpu_create(type) instead of cpu_init(cpu_model)
With all targets defining CPU_RESOLVING_TYPE, refactor
cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model)
so that callers won't have to know internal resolving cpu
type. Place it in exec.c so it could be called from both
target independed vl.c and *-user/main.c.

That allows us to stop abusing cpu type from
  MachineClass::default_cpu_type
as resolver class in vl.c which were confusing part of
cpu_parse_cpu_model().

Also with new parse_cpu_model(), the last users of cpu_init()
in null-machine.c and bsd/linux-user targets could be switched
to cpu_create() API and cpu_init() API will be removed by
follow up patch.

With no longer users left remove MachineState::cpu_model field,
new code should use MachineState::cpu_type instead and
leave cpu_model parsing to generic code in vl.c.

Markus Armbruster 112ed241f5 qapi: Empty out qapi-schema.json
The previous commit improved compile time by including less of the
generated QAPI headers.  This is impossible for stuff defined directly
in qapi-schema.json, because that ends up in headers that that pull in
everything.

Move everything but include directives from qapi-schema.json to new
sub-module qapi/misc.json, then include just the "misc" shard where
possible.

It's possible everywhere, except:

* monitor.c needs qmp-command.h to get qmp_init_marshal()

* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
  qapi-event.h to get enum QAPIEvent

Perhaps we'll get rid of those some other day.

Adding a type to qapi/migration.json now recompiles some 120 instead
of 2300 out of 5100 objects.

The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h,
qapi-types.h.  Each of these headers still includes all its shards.
Reduce compile time by including just the shards we actually need.

To illustrate the benefits: adding a type to qapi/migration.json now
recompiles some 2300 instead of 4800 objects.  The next commit will
improve it further.

Peter Maydell 5edb1b3fa9 hw/core/split-irq: Device that splits IRQ lines
In some board or SoC models it is necessary to split a qemu_irq line
so that one input can feed multiple outputs.  We currently have
qemu_irq_split() for this, but that has several deficiencies:
 * it can only handle splitting a line into two
 * it unavoidably leaks memory, so it can't be used
   in a device that can be deleted

Implement a qdev device that encapsulates splitting of IRQs, with a
configurable number of outputs.  (This is in some ways the inverse of
the TYPE_OR_IRQ device.)

Peter Maydell 4a151677a8 qdev: Add new qdev_init_gpio_in_named_with_opaque()
The function qdev_init_gpio_in_named() passes the DeviceState pointer
as the opaque data pointor for the irq handler function.  Usually
this is what you want, but in some cases it would be helpful to use
some other data pointer.

Add a new function qdev_init_gpio_in_named_with_opaque() which allows
the caller to specify the data pointer they want.

Peter Maydell 97df5feee3 loader: Add new load_ramdisk_as()
Add a function load_ramdisk_as() which behaves like the existing
load_ramdisk() but allows the caller to specify the AddressSpace
to use. This matches the pattern we have already for various
other loader functions.

Ensure that the post write hook is called during reset. This allows us
to rely on the post write functions instead of having to call them from
the reset() function.
