scripts/cocci: Patch to let devices own their MemoryRegions
When a device creates a MemoryRegion without setting its ownership,
the MemoryRegion is added to the machine "/unattached" container in
the QOM tree.
Example with the Samsung SMDKC210 board:
$ arm-softmmu/qemu-system-arm -M smdkc210 -S -monitor stdio
(qemu) info qom-tree
/machine (smdkc210-machine)
/unattached (container)
/io[0] (qemu:memory-region)

/exynos4210.irom[0] (qemu:memory-region)
/exynos4210.iram[0] (qemu:memory-region)
/exynos4210.chipid[0] (qemu:memory-region)
...
/device[26] (exynos4210.uart)
/exynos4210.uart[0] (qemu:memory-region)
/soc (exynos4210)

exec/rom_reset: Free rom data during inmigrate skip
Commit
355477f8c73e9 skips rom reset when we're an incoming migration
so as not to overwrite shared ram in the ignore-shared migration
optimisation.
However, it's got an unexpected side effect that because it skips
freeing the ROM data, when rom_reset gets called later on, after
migration (e.g. during a reboot), the ROM does get reset to the original
file contents. Because of seabios/x86's weird reboot process
this confuses a reboot into hanging after a migration.
Fixes:

Use -isystem for linux-headers dir
glibc and Linux-provided headers are known to generate macro
redefinition warnings when used together. For example:
<linux/mman.h> and <sys/mman.h> duplicate some macro definitions.
We normally never see those warnings because GCC suppresses
warnings generated by system headers. We carry our own copy of
Linux header files, though, and this makes those warnings not be
suppressed when glibc headers are included before Linux headers
(e.g. if <sys/mman.h> is included before <linux/mman.h>).
Use -isystem instead of -I for linux-headers. This makes the
compiler treat our linux-headers directory the same way it treats
system-provided Linux headers, and suppress warnings generated by
them.

When adding object (or class) uint types, one must therefore use the

This enhances the uint-specific property helper APIs by adding a

this paramater to OBJ_PROP_FLAG_READ. This maintains the current
behaviour whilst allowing others to also set OBJ_PROP_FLAG_WRITE (or use
the more convenient OBJ_PROP_FLAG_READWRITE) in the future (which will
automatically install a setter). Other flags may be added later.

configure: Fix building with SASL on Windows
The Simple Authentication and Security Layer (SASL) library
re-defines the struct iovec on Win32 [*]. QEMU also re-defines
it in "qemu/osdep.h". The two definitions then clash on a MinGW
build.
We can avoid the SASL definition by defining STRUCT_IOVEC_DEFINED.
Since QEMU already defines 'struct iovec' if it is missing, add
the definition to vnc_sasl_cflags to avoid SASL re-defining it.

modules: load modules from versioned /var/run dir
On upgrades the old .so files usually are replaced. But on the other
hand since a qemu process represents a guest instance it is usually kept
around.
That makes late addition of dynamic features e.g. 'hot-attach of a ceph
disk' fail by trying to load a new version of e.f. block-rbd.so into an
old still running qemu binary.
This adds a fallback to also load modules from a versioned directory in the
temporary /var/run path. That way qemu is providing a way for packaging
to store modules of an upgraded qemu package as needed until the next reboot.
An example how that can then be used in packaging can be seen in:

This is because the Make-based build-system use a global namespace for

Note: this kind of variable clashing is hard to fix or prevent
currently. meson should help, as declarations have a linear

Note2: we have a lot of main.c (or other duplicated names!) in

COLO: Optimize memory back-up process
This patch will reduce the downtime of VM for the initial process,
Previously, we copied all these memory in preparing stage of COLO
while we need to stop VM, which is a time-consuming process.
Here we optimize it by a trick, back-up every page while in migration
process while COLO is enabled, though it affects the speed of the
migration, but it obviously reduce the downtime of back-up all SVM'S
memory in COLO preparing stage.

migration/throttle: Add throttle-trig-thres migration parameter
Currently, if the bytes_dirty_period is more than the 50% of
bytes_xfer_period, we start or increase throttling.
If we make this percentage higher, then we can tolerate higher
dirty rate during migration, which means less impact on guest.
The side effect of higher percentage is longer migration time.
We can make this parameter configurable to switch between mig-
ration time first or guest performance first.
The default value is 50 and valid range is 1 to 100.

hw/arm/virt: kvm: allow gicv3 by default if v2 cannot work
At the moment if the end-user does not specify the gic-version along
with KVM acceleration, v2 is set by default. However most of the
systems now have GICv3 and sometimes they do not support GICv2
compatibility.
This patch keeps the default v2 selection in all cases except
in the KVM accelerated mode when either
- the host does not support GICv2 in-kernel emulation or
- number of VCPUS exceeds 8.
Those cases did not work anyway so we do not break any compatibility.
Now we get v3 selected in such a case.

hw/arm/virt: kvm: Restructure finalize_gic_version()
Restructure the finalize_gic_version with switch cases and
clearly separate the following cases:
- KVM mode / in-kernel irqchip
- KVM mode / userspace irqchip
- TCG mode
In KVM mode / in-kernel irqchip , we explictly check whether
the chosen version is supported by the host. If the end-user
explicitly sets v2/v3 and this is not supported by the host,
then the user gets an explicit error message. Note that for
old kernels where the CREATE_DEVICE ioctl doesn't exist then
we will now fail if the user specifically asked for gicv2,
where previously we (probably) would have succeeded.
In KVM mode / userspace irqchip we immediatly output an error
in case the end-user explicitly selected v3. Also we warn the
end-user about the unexpected usage of gic-version=host in
that case as only userspace GICv2 is supported.

tests/boot_linux_console: Add initrd test for the Orange Pi PC board
This test boots a Linux kernel on a OrangePi PC board and verify
the serial output is working.
The kernel image and DeviceTree blob are built by the Armbian
project (based on Debian):

The following RTC functionality and features are implemented:
* Year-Month-Day read/write

* General Purpose storage
The following boards are extended with the RTC device:
* Cubieboard (hw/arm/cubieboard.c)

hw/arm/allwinner-h3: add Boot ROM support
A real Allwinner H3 SoC contains a Boot ROM which is the
first code that runs right after the SoC is powered on.
The Boot ROM is responsible for loading user code (e.g. a bootloader)
from any of the supported external devices and writing the downloaded
code to internal SRAM. After loading the SoC begins executing the code
written to SRAM.
This commits adds emulation of the Boot ROM firmware setup functionality
by loading user code from SD card in the A1 SRAM. While the A1 SRAM is
64KiB, we limit the size to 32KiB because the real H3 Boot ROM also rejects
sizes larger than 32KiB. For reference, this behaviour is documented
by the Linux Sunxi project wiki at:
