Per cxl r3.2 Section 9.13.3.3, extent capacity tracking should include
extents in different states including added, pending, etc.
Before the change, for the in-device extent number tracking purpose, we only
have "total_extent_count" defined, which only tracks the number of
extents accepted. However, we need to track number of extents in other
states also, for now it is extents pending-to-add.
To fix that, we introduce a new counter for dynamic capacity
"nr_extents_accepted" which explicitly tracks number of the extents
accepted by the hosts, and fix "total_extent_count" to include
both accepted and pending extents counting.

Some sysbus devices have conditional mmio regions. This
happens for instance with the hw/acpi/ged device. In that case
it becomes difficult to predict which index a specific MMIO
region corresponds to when one needs to mmio map the region.
Introduce a new helper that takes the name of the region instead
of its index. If the region is not found this returns -1.
Otherwise it maps the corresponding index and returns this latter.

QEMU will notify the OS about PCI hotplug/hotunplug events through
GED interrupts. Let the GED device handle a new PCI hotplug event.
On its occurrence it calls the \\_SB.PCI0.PCNT method with the BLCK
mutex held.
The GED device uses a dedicated MMIO region that will be mapped
by the machine code.
At this point the GED still does not support PCI device hotplug in
its TYPE_HOTPLUG_HANDLER implementation. This will come in a

To keep "qemu/target-info.h" self-contained to native
types, declare target_arch() -- which returns a QAPI
type -- in "qemu/target-info-qapi.h".
No logical change.
Keeping native types in "qemu/target-info.h" is necessary
to keep building tests such tests/tcg/plugins/mem.c, as
per the comment added in commit ecbcc9ead2 ("tests/tcg:
add a system test to check memory instrumentation"):
/*
* plugins should not include anything from QEMU aside from the
* API header. However as this is a test plugin to exercise the
* internals of QEMU and we want to avoid needless code duplication we
* do so here. bswap.h is pretty self-contained although it needs a
* few things provided by compiler.h.

This will be necessary for devices implementing ATS.
We also define a new macro IOMMU_ACCESS_FLAG_FULL in addition to
IOMMU_ACCESS_FLAG to support more access flags.
IOMMU_ACCESS_FLAG is kept for convenience and backward compatibility.
Here are the flags added (defined by the PCIe 5 specification) :
- Execute Requested
- Privileged Mode Requested
- Global
- Untranslated Only
IOMMU_ACCESS_FLAG sets the additional flags to 0

Allow user to set a preferred scale (defaulting to 1) of the virtual
display. Along with zoom-to-fix=false, this would be helpful for users
running QEMU on hi-dpi host desktop to achieve pixel to pixel display --
e.g., if the scale factor of a user's host desktop is set to 200%, then
they can set a 0.5 scale for the virtual display to avoid magnification
that might cause blurriness.

When aspect ratio of host window and that of guest display are not
aligned, we can either zoom the guest content to fill the whole host
window or add padding to respect aspect ratio of the guest. Add an
option keep-aspect-ratio to allow users to select their preferred
behavior in this case.

Thanks to 72d277a7, 1ed2cb32, and others, EDID (Extended Display
Identification Data) is propagated by QEMU such that a virtual display
presents legitimate metadata (e.g., name, serial number, preferred
resolutions, etc.) to its connected guest.
This change adds the ability to specify the EDID name for a particular
virtio-vga display. Previously, every virtual display would have the same
name: "QEMU Monitor". Now, we can inject names of displays in order to test
guest behavior that is specific to display names. We provide the ability to
inject the display name from the frontend since this is guest visible
data. Furthermore, this makes it clear where N potential display outputs
would get their name from (which will be added in a future change).
Note that we have elected to use a struct here for output data for
extensibility - we intend to add per-output fields like resolution in a
future change.
It should be noted that EDID names longer than 12 bytes will be truncated
per spec (I think?).
Testing: verified that when I specified 2 outputs for a virtio-gpu with
edid_name set, the names matched those that I configured with my vnc
display.
-display vnc=localhost:0,id=aaa,display=vga,head=0 \
-display vnc=localhost:1,id=bbb,display=vga,head=1 \
-device '{"driver":"virtio-vga",
"max_outputs":2,
"id":"vga",
"outputs":[
{
"name":"AAA"
},
{
"name":"BBB"
}
]}'
