This script compares the vmstate dumps in JSON format as output by QEMU
with the -dump-vmstate option.
It flags various errors, like version mismatch, sections going away,
size mismatches, etc.
This script is tolerant of a few changes that do not change the on-wire
format, like embedding a few fields within substructs.
The script takes -s/--src and -d/--dest parameters, to which filenames
are given as arguments.
Example:
(in a qemu 2.0 tree):
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate qemu-2.0.json
(in a qemu 2.2 tree:)
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate -M pc-i440fx-2.0 \
qemu-2.2-m2.0.json
./scripts/vmstate-static-checker.py -s qemu-2.0.json -d qemu-2.2-m2.0.json
The script also takes a --reverse parameter to switch the src and dest
jsons. This is just a shorthand for reversing the src and dest.
The --help parameter shows usage information.

This commit adds a new command, '-dump-vmstate', that takes a filename
as an argument. When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.
The JSON-format output can then be used to compare the vmstate info for
different QEMU versions, specifically to test whether live migration
would break due to changes in the vmstate data.
A Python script that compares the output of such JSON dumps is included
in the following commit.

This will let threads other than the I/O thread raise QMP events.
GIOChannel is thread-safe, and send and receive state is usually
well-separated. The only driver that requires some care is the
pty driver, where some of the state is shared by the read and write
sides. That state is protected with the chr_write_lock too.

This is a pc & q35 only machine opt.
If you add enough PCI devices then all mmio for them will not fit
below 4G which may not be the layout the user wanted. This allows
you to increase the below 4G address space that PCI devices can use
(aka decrease ram below 4G) and therefore in more cases not have any
mmio that is above 4G.
For example using "-machine pc,max-ram-below-4g=2G" on the command
line will limit the amount of ram that is below 4G to 2G.
Note: this machine option cannot be used to increase the amount
of ram below 4G.

qapi-event.py will parse the schema and generate qapi-event.c, then
the API in qapi-event.c can be used to handle events in qemu code.
All API have prefix "qapi_event".
The script mainly includes two parts: generate API for each event
define, generate an enum type for all defined events.
Since in some cases the real emit behavior may change, for example,
qemu-img would not send a event, a callback layer is used to
control the behavior. As a result, the stubs at compile time
can be saved, the binding of block layer code and monitor code
will become looser.
