The command will retrieve and print either all VM-level statistics,

Introduce a simple filtering of statistics, that allows to retrieve
statistics for a subset of the guest vCPUs. This will be used for
example by the HMP monitor, in order to retrieve the statistics
for the currently selected CPU.
Example:
{ "execute": "query-stats",
"arguments": {
Allow the user to request statistics for a single provider of interest.

Hi; in real hardware an SMMUv3 might be sat in front of any
DMA-capable device. Putting one in front of a PCI bus is common
but not the only use case. Does QEMU's SMMUv3 model handle that,
or is the implementation currently restricted to only handling DMA
from PCI devices?

Hello,
If you want, you can break migration compatibility. I don't see it as a problem.

Implements the Convert Declets To Binary Coded Decimal instruction.
Since libdecnumber doesn't expose the methods for direct conversion
(decDigitsFromDPD, DPD2BCD, etc), a positive decimal32 with zero
exponent is used as an intermediate value to convert the declets.

it is not possible to disable MPX on a "-cpu host" just by adding "-mpx"

Adds an insns_flags2 for the BCD assist instructions introduced in
Power ISA 2.06. These instructions are not listed in the manuals for
e5500[1] and e6500[2], so the flag is only added for POWER7/8/9/10
models.
