The header file sizes.h is used in linux kernel,
barebox bootloader and u-boot bootloader. It provides
the short and easy-to-read names for power-of-two
numbers. The numbers like this are othen used
for memory range sizes.
This commits imports the sizes.h from barebox bootloader
source code (see

[RFC 1/2] include/: import sizes.h from barebox

The sizes.h macros is a easy-to-read method of
power-of-two memory sizes representation. The sizes.h
macros are actively used in linux kernel and other
projects, so let's use them in QEMU too.

Set the guest numa nodes memory policies using the mbind(2)

After this patch, we are able to set guest nodes memory policies

And as you all know, if PCI-passthrough is used,
If the total number of the assigned numa nodes memory is not

check it to ensure that we write the right data to ACPI

It is only used there and is deemed very fragile if not incorrect in its
current memcpy() form. Moving it into linux-user will allow to move
parts into target_cpu.h headers and only copy what the ABI mandates.

This allows to drop env in tb_invalidate_phys_page_range().
Note that the argument is unused.

Add the numa_info structure to contain the numa nodes memory,
VCPUs information and the future added numa nodes host memory
policies.

This is an RFC patch.
The modern Linux kernel supports every known POWERPC CPU so when
it boots, it can always find a matching cpu_spec from the cpu_specs array.
However if the kernel is quite old, it may be missing the definition of
the actual CPU. To provide ability for old kernels to work on

When the initial SP is loaded from the vector table on ARMv7M systems the two
least significant bits are ignored as the stack is always aligned at a four byte
boundary (see ARM DDI 0403C, B1.4.1 and B1.5.5). So far QEMU did not ignore
these bits leading to a stack alignment inconsitent with real ha

KVM request types are normally defined using hex constants but QEMU traces
print decimal values instead, which is not very convenient.
This changes the request type format from %d to %x.

so, the guest disk write cache just only for none and writeback cache mode?

w32/w64 properties that we report in QOM are
currently static, but this is wrong:
guest firmware can select its own windows:
optimal placement for w64 is guest-dependent, further,
for Q35, w32 is affected by the MCFG base and size.
This detects the actual window configuration used by guest
and rep
For Q35, MMCFG address and size are guest configurable.
Update w32 property to make it behave accordingly.
