Unlike pam_update() which takes the subject -- PAMMemoryRegion -- as
first argument, init_pam() takes it as fifth (!) argument. This makes it
quite hard to figure out what an init_pam() invocation actually
initializes. By moving the subject to the front this should become
clearer.
While at it, lower the DeviceState parameter to Object, also
communicating more clearly that this parameter is just the owner rather
than some (heavy?) dependency.

Since it's implementation on v8.0.0-rc0, having the PCI_ERR_UNCOR_MASK

This commit enables each CXL Type-3 device to contain one volatile
memory region and one persistent region.
Two new properties have been added to cxl-type3 device initialization:
[volatile-memdev] and [persistent-memdev]
The existing [memdev] property has been deprecated and will default the
memory region to a persistent memory region (although a user may assign
the region to a ram or file backed region). It cannot be used in
combination with the new [persistent-memdev] property.
Partitioning volatile memory from persistent memory is not yet supported.
Volatile memory is mapped at DPA(0x0), while Persistent memory is mapped
at DPA(vmem->size), per CXL Spec 8.2.9.8.2.0 - Get Partition Info.

Kernel commit 292a7d6fca33 ("KVM: s390: pv: fix asynchronous teardown

if the VM is not larger than 2GiB. QEMU would attempt it and fail,
print an error message, and then proceed with a normal teardown.
Avoid attempting to use asynchronous teardown altogether when the VM is
not larger than 2 GiB. This will avoid triggering the error message and
also avoid pointless overhead; normal teardown is fast enough for small
VMs.

The lifetime of the PCIBridgeWindows instance accessed via the windows pointer
in struct PCIBridge is managed separately from the PCIBridge itself.
Triggered by ./qemu-system-x86_64 -M x-remote -display none -monitor stdio
QEMU monitor: device_add cxl-downstream
In some error handling paths (such as the above due to attaching a cxl-downstream
port anything other than a cxl-upstream port) the g_free() of the PCIBridge
windows in pci_bridge_region_cleanup() is called before the final call of
flatview_uref() in address_space_set_flatview() ultimately from
drain_call_rcu()
At one stage this resulted in a crash, currently can still be observed using
valgrind which records a use after free.
When present, only one instance is allocated. pci_bridge_update_mappings()
can operate directly on an instance rather than creating a new one and
swapping it in. Thus there appears to be no reason to not directly
couple the lifetimes of the two structures by embedding the PCIBridgeWindows
within the PCIBridge removing the need for the problematic separate free.
Patch is same as was posted deep in the discussion.

The arm boot.c code includes a utility function write_bootloader()
which assists in writing a boot-code fragment into guest memory,
including handling endianness and fixing it up with entry point
addresses and similar things. This is useful not just for the boot.c
code but also in board model code, so rename it to
arm_write_bootloader() and make it globally visible.
Since we are making it public, make its API a little neater: move the
AddressSpace* argument to be next to the hwaddr argument, and allow
the fixupcontext array to be const, since we never modify it in this
function.

This query copies the kernel command line into the message buffer. It
was previously stubbed out to return empty, this commit makes it reflect
the arguments specified with `-append`.
I observed the following peculiarities on my Pi 3B+:
- If the buffer is shorter than the string, the response header gives
the full length, but no data is actually copied.
- No NUL terminator is added: even if the buffer is long enough to fit
one, the buffer's original contents are preserved past the string's
end.
- The VC firmware adds the following extra parameters beside the
user-supplied ones (via /boot/cmdline.txt): `video`, `vc_mem.mem_base`
and `vc_mem.mem_size`. This is currently not implemented in qemu.

Previously, PXB_CXL_DEVICE, PXB_PCIE_DEVICE and PXB_DEVICE all
have PCI_DEVICE as their direct parent but share a common state
struct PXBDev. convert_to_pxb() is used to get the PXBDev
instance from which ever of these types it is called on.
This patch switches to an explicit hierarchy based on shared
functionality. To allow use of OBJECT_DECLARE_SIMPLE_TYPE()
whilst minimizing code changes, all types are renamed to have
the postfix _DEV rather than _DEVICE. The new heirarchy
has PXB_CXL_DEV with parent PXB_PCIE_DEV which in turn
has parent PXB_DEV which continues to have parent PCI_DEVICE.
This allows simple use of PXB_DEV() etc rather than a custom function
+ removal of duplicated properties and moving the CXL specific
elements out of struct PXBDev.

This patch provides accessor functions as replacements for direct
access to slot_reserved_mask according to the comment at the top
of include/hw/pci/pci_bus.h which advises that data structures for
PCIBus should not be directly accessed but instead be accessed using
accessor functions in pci.h.
Three accessor functions can conveniently replace all direct accesses
of slot_reserved_mask. With this patch, the new accessor functions are
used in hw/sparc64/sun4u.c and hw/xen/xen_pt.c and pci_bus.h is removed
from the included header files of the same two files.
No functional change intended.

Optimize the virtio-balloon feature on the ARM platform by adding
a variable to keep track of the current hot-plugged pc-dimm size,
instead of traversing the virtual machine's memory modules to count
the current RAM size during the balloon inflation or deflation
process. This variable can be updated only when plugging or unplugging
the device, which will result in an increase of approximately 60%
efficiency of balloon process on the ARM platform.
We tested the total amount of time required for the balloon inflation process on ARM:
inflate the balloon to 64GB of a 128GB guest under stress.

When a virtqueue size is changed by the guest via
virtio_queue_set_num(), its region cache is not automatically updated.
If the size was increased, this could lead to accessing the cache out
of bounds. For example, in vring_get_used_event():
static inline uint16_t vring_get_used_event(VirtQueue *vq)
{
return vring_avail_ring(vq, vq->vring.num);
}
static inline uint16_t vring_avail_ring(VirtQueue *vq, int i)
{
VRingMemoryRegionCaches *caches = vring_get_region_caches(vq);
hwaddr pa = offsetof(VRingAvail, ring[i]);
if (!caches) {
return 0;
}
return virtio_lduw_phys_cached(vq->vdev, &caches->avail, pa);
}
vq->vring.num will be greater than caches->avail.len, which will
trigger a failed assertion down the call path of
virtio_lduw_phys_cached().
Fix this by calling virtio_init_region_cache() after
virtio_queue_set_num() if we are not already calling
virtio_queue_set_rings(). In the legacy path this is already done by
virtio_queue_update_rings().

Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices.
This commit includes changes for the common code.
- Added support for the new checksum registers which are required for
the I2C support. The checksum calculation is handled in the qemu
common code.
- Added wrapper function for read and write data so that I2C code can
call it without MMIO interface.
The TPM TIS I2C spec describes in the table in section "Interface Locality
Usage per Register" that the TPM_INT_ENABLE and TPM_INT_STATUS registers
must be writable for any locality even if the locality is not the active
locality. Therefore, remove the checks whether the writing locality is the
active locality for these registers.

The SOC on i.MX6UL and i.MX7 has 2 Ethernet interfaces. The PHY on each may
be connected to separate MDIO busses, or both may be connected on the same
MDIO bus using different PHY addresses. Commit 461c51ad42 ("Add a phy-num
property to the i.MX FEC emulator") added support for specifying PHY
addresses, but it did not provide support for linking the second PHY on
a given MDIO bus to the other Ethernet interface.
To be able to support two PHY instances on a single MDIO bus, two properties
are needed: First, there needs to be a flag indicating if the MDIO bus on
a given Ethernet interface is connected. If not, attempts to read from this
bus must always return 0xffff. Implement this property as phy-connected.
Second, if the MDIO bus on an interface is active, it needs a link to the
consumer interface to be able to provide PHY access for it. Implement this
property as phy-consumer.

Migrate rtc_ref (which only needs to be 32-bit because it is summed to
a 32-bit register), which requires bumping the migration version.

While at it, drop the write-only field rtc from LasiState.

CPU watchpoints can be use by non-TCG accelerators.
KVM uses them:

target/i386/kvm/kvm.c:5216:static CPUWatchpoint hw_watchpoint;

See for example commit e4482ab7e3 ("target-arm: kvm - add support

This adds basic support for HW assisted debug. The ioctl interface
to KVM allows us to pass an implementation defined number of break
