Currently the gpex PCI controller implements no special behaviour for
guest accesses to areas of the PIO and MMIO where it has not mapped
any PCI devices, which means that for Arm you end up with a CPU
exception due to a data abort.
Most host OSes expect "like an x86 PC" behaviour, where bad accesses
like this return -1 for reads and ignore writes. In the interests of
not being surprising, make host CPU accesses to these windows behave
as -1/discard where there's no mapped PCI device.
The old behaviour generally didn't cause any problems, because
almost always the guest OS will map the PCI devices and then only
access where it has mapped them. One corner case where you will see
this kind of access is if Linux attempts to probe legacy ISA
devices via a PIO window access. So far the only case where we've
seen this has been via the syzkaller fuzzer.

For accesses to rom blob data before or during reset, we have a
function rom_ptr() which looks for a rom blob that would be loaded to
the specified address, and returns a pointer into the rom blob data
corresponding to that address. This allows board or CPU code to say
"what is the data that is going to be loaded to this address?".
However, this function does not take account of memory region
aliases. If for instance a machine model has RAM at address
0x0000_0000 which is aliased to also appear at 0x1000_0000, a
rom_ptr() query for address 0x0000_0000 will only return a match if
the guest image provided by the user was loaded at 0x0000_0000 and
not if it was loaded at 0x1000_0000, even though they are the same
RAM and a run-time guest CPU read of 0x0000_0000 will read the data
loaded to 0x1000_0000.
Provide a new function rom_ptr_for_as() which takes an AddressSpace
argument, so that it can check whether the MemoryRegion corresponding
to the address is also mapped anywhere else in the AddressSpace and
look for rom blobs that loaded to that alias.

Currently, the default msix vectors for virtio-net-pci is 3 which is
obvious not suitable for multiqueue guest, so we depends on the user
or management tools to pass a correct vectors parameter. In fact, we
can simplifying this by calculating the number of vectors on realize.
Consider we have N queues, the number of vectors needed is 2*N + 2
(#queue pairs + plus one config interrupt and control vq). We didn't
check whether or not host support control vq because it was added
unconditionally by qemu to avoid breaking legacy guests such as Minix.

Hypervisors, especially type-1 ones, need the firmware/bootcode to put
their initial guest somewhere in memory and pass the information to it
via platform data. The guest-loader is modelled after the generic
loader for exactly this sort of purpose:
$QEMU $ARGS -kernel ~/xen.git/xen/xen \
-append "dom0_mem=1G,max:1G loglvl=all guest_loglvl=all" \
-device guest-loader,addr=0x42000000,kernel=Image,bootargs="root=/dev/sda2 ro console=hvc0 earlyprintk=xen" \
-device guest-loader,addr=0x47000000,initrd=rootfs.cpio

The Clock framework allows users to specify a callback which is
called after the clock's period has been updated. Some users need to
also have a callback which is called before the clock period is
updated.
As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.
Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

If SMM is not supported, ACPI fixed hardware doesn't support
legacy-mode. ACPI-only platform. Where SCI_EN in PM1_CNT register is
always set.
The bit tells OS legacy mode(SCI_EN cleared) or ACPI mode(SCI_EN set).
With the next patch (setting fadt.smi_cmd = 0 when smm isn't enabled),
guest Linux tries to switch to ACPI mode, finds smi_cmd = 0, and then
fails to initialize acpi subsystem. This patch proactively fixes it.
This patch changes guest ABI. To keep compatibility, use
"smm-compat" introduced by earlier patch. If the property is true,
disable new behavior.

The default behaviour for virtio devices is not to use the platforms normal
DMA paths, but instead to use the fact that it's running in a hypervisor
to directly access guest memory. That doesn't work if the guest's memory
is protected from hypervisor access, such as with AMD's SEV or POWER's PEF.
So, if a confidential guest mechanism is enabled, then apply the
iommu_platform=on option so it will go through normal DMA mechanisms.
Those will presumably have some way of marking memory as shared with
the hypervisor or hardware so that DMA will work.

Currently the "memory-encryption" property is only looked at once we
get to kvm_init(). Although protection of guest memory from the
hypervisor isn't something that could really ever work with TCG, it's
not conceptually tied to the KVM accelerator.
In addition, the way the string property is resolved to an object is
almost identical to how a QOM link property is handled.
So, create a new "confidential-guest-support" link property which sets
this QOM interface link directly in the machine. For compatibility we
keep the "memory-encryption" property, but now implemented in terms of
the new property.

When the "memory-encryption" property is set, we also disable KSM
merging for the guest, since it won't accomplish anything.
We want that, but doing it in the property set function itself is
thereoretically incorrect, in the unlikely event of some configuration
environment that set the property then cleared it again before
constructing the guest.
More importantly, it makes some other cleanups we want more difficult.
So, instead move this logic to machine_run_board_init() conditional on
the final value of the property.

Commit 9d7bd0826f introduced a new 'use-disabled-flag' property
set to true by default.
To allow the migration, we set this property to false in the hw_compat,
but in the wrong place (hw_compat_4_1).
Since commit 9d7bd0826f was released with QEMU 5.0, we move
'use-disabled-flag' property to hw_compat_4_2, so 4.2 machine types
will have the pre-patch behavior and the migration can work.
The issue was discovered with vhost-vsock device and 4.2 machine
type without running any kernel in the VM:

The ptimer API currently provides two methods for setting the period:
ptimer_set_period(), which takes a period in nanoseconds, and
ptimer_set_freq(), which takes a frequency in Hz. Neither of these
lines up nicely with the Clock API, because although both the Clock
and the ptimer track the frequency using a representation of whole
and fractional nanoseconds, conversion via either period-in-ns or
frequency-in-Hz will introduce a rounding error.
Add a new function ptimer_set_period_from_clock() which takes the
Clock object directly to avoid the rounding issues. This includes a
facility for the user to specify that there is a frequency divider
between the Clock proper and the timer, as some timer devices like
the CMSDK APB dualtimer need this.
To avoid having to drag in clock.h from ptimer.h we add the Clock
type to typedefs.h.

Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND(). But places where we must keep the list in order
by appending remain open-coded until later patches.
Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

Only softmmu code uses DEFINE_PROP_UUID, and it currently depends
on error_set_from_qdev_prop_error(). Move it to
qdev-properties-system.c to get out of our way when refactoring
the qdev property system.
We can eventually move it back to the core property system later,
after removing usage of error_set_from_qdev_prop_error().

In rom_check_and_register_reset() we report to the user if there is
a "ROM region overlap". This has a couple of problems:
* the reported information is not very easy to intepret
* the function just prints the overlap to stderr (and relies on
its single callsite in vl.c to do an error_report() and exit)
* only the first overlap encountered is diagnosed
Make this function use error_report() and error_printf() and
report a more user-friendly report with all the overlaps
diagnosed.
Sample old output:
rom: requested regions overlap (rom dtb. free=0x0000000000008000, addr=0x0000000000000000)
qemu-system-aarch64: rom check and register reset failed
Sample new output:
qemu-system-aarch64: Some ROM regions are overlapping
These ROM regions might have been loaded by direct user request or by default.
They could be BIOS/firmware images, a guest kernel, initrd or some other file loaded into guest memory.
Check whether you intended to load all this guest code, and whether it has been built to load to the correct addresses.
The following two regions overlap (in the cpu-memory-0 address space):
phdr #0: /home/petmay01/linaro/qemu-misc-tests/ldmia-fault.axf (addresses 0x0000000000000000 - 0x0000000000008000)
dtb (addresses 0x0000000000000000 - 0x0000000000100000)
The following two regions overlap (in the cpu-memory-0 address space):
phdr #1: /home/petmay01/linaro/qemu-misc-tests/bad-psci-call.axf (addresses 0x0000000040000000 - 0x0000000040000010)
phdr #0: /home/petmay01/linaro/qemu-misc-tests/bp-test.elf (addresses 0x0000000040000000 - 0x0000000040000020)

In rom_check_and_register_reset() we detect overlaps by looking at
whether the ROM blob we're currently examining is in the same address
space and starts before the previous ROM blob ends. (This works
because the ROM list is kept sorted in order by AddressSpace and then
by address.)
Instead of keeping the AddressSpace and last address of the previous ROM
blob in local variables, just keep a pointer to it.
This will allow us to print more useful information when we do detect
an overlap.
