target/arm: Default to 1GHz cntfrq for 'max' and new CPUs

In previous versions of the Arm architecture, the frequency of the
generic timers as reported in CNTFRQ_EL0 could be any IMPDEF value,
and for QEMU we picked 62.5MHz, giving a timer tick period of 16ns.
In Armv8.6, the architecture standardized this frequency to 1GHz.

Because there is no ID register feature field that indicates whether
a CPU is v8.6 or that it ought to have this counter frequency, we
implement this by changing our default CNTFRQ value for all CPUs,
with exceptions for backwards compatibility:

* CPU types which we already implement will retain the old
default value. None of these are v8.6 CPUs, so this is
architecturally OK.
* CPUs used in versioned machine types with a version of 9.0
or earlier will retain the old default value.

The upshot is that the only CPU type that changes is 'max'; but any
new type we add in future (whether v8.6 or not) will also get the new
1GHz default.

It remains the case that the machine model can override the default
value via the 'cntfrq' QOM property (regardless of the CPU type).

hw/core/machine: Introduce the module as a CPU topology level

In x86, module is the topology level above core, which contains a set
of cores that share certain resources (in current products, the resource
usually includes L2 cache, as well as module scoped features and MSRs).

Though smp.clusters could also share the L2 cache resource [1], there
are following reasons that drive us to introduce the new smp.modules:

* As the CPU topology abstraction in device tree [2], cluster supports
nesting (though currently QEMU hasn't support that). In contrast,
(x86) module does not support nesting.

* Due to nesting, there is great flexibility in sharing resources
on cluster, rather than narrowing cluster down to sharing L2 (and
L3 tags) as the lowest topology level that contains cores.

* Flexible nesting of cluster allows it to correspond to any level
between the x86 package and core.

* In Linux kernel, x86's cluster only represents the L2 cache domain
but QEMU's smp.clusters is the CPU topology level. Linux kernel will
also expose module level topology information in sysfs for x86. To
avoid cluster ambiguity and keep a consistent CPU topology naming
style with the Linux kernel, we introduce module level for x86.

The module is, in existing hardware practice, the lowest layer that
contains the core, while the cluster is able to have a higher
topological scope than the module due to its nesting.

Therefore, place the module between the cluster and the core:

drawer/book/socket/die/cluster/module/core/thread

With the above topological hierarchy order, introduce module level
support in MachineState and MachineClass.

HostMem: Add mechanism to opt in kvm guest memfd via MachineState

Add a new member "guest_memfd" to memory backends. When it's set
to true, it enables RAM_GUEST_MEMFD in ram_flags, thus private kvm
guest_memfd will be allocated during RAMBlock allocation.

Memory backend's @guest_memfd is wired with @require_guest_memfd
field of MachineState. It avoid looking up the machine in phymem.c.

MachineState::require_guest_memfd is supposed to be set by any VMs
that requires KVM guest memfd as private memory, e.g., TDX VM.

hw/i386/q35: Set virtio-iommu aw-bits default value to 39

Currently the default input range can extend to 64 bits. On x86,
when the virtio-iommu protects vfio devices, the physical iommu
may support only 39 bits. Let's set the default to 39, as done
for the intel-iommu.

We use hw_compat_8_2 to handle the compatibility for machines
before 9.0 which used to have a virtio-iommu default input range
of 64 bits.

Of course if aw-bits is set from the command line, the default
is overriden.

virtio-iommu: Change the default granule to the host page size

We used to set the default granule to 4KB but with VFIO assignment
it makes more sense to use the actual host page size.

Indeed when hotplugging a VFIO device protected by a virtio-iommu
on a 64kB/64kB host/guest config, we current get a qemu crash:

"vfio: DMA mapping failed, unable to continue"

This is due to the hot-attached VFIO device calling
memory_region_iommu_set_page_size_mask() with 64kB granule
whereas the virtio-iommu granule was already frozen to 4KB on
machine init done.

Set the granule property to "host" and introduce a new compat.
The page size mask used before 9.0 was qemu_target_page_mask().
Since the virtio-iommu currently only supports x86_64 and aarch64,
this matched a 4KB granule.

Note that the new default will prevent 4kB guest on 64kB host
because the granule will be set to 64kB which would be larger
than the guest page size. In that situation, the virtio-iommu
driver fails on viommu_domain_finalise() with
"granule 0x10000 larger than system page size 0x1000".

In that case the workaround is to request 4K granule.

The current limitation of global granule in the virtio-iommu
should be removed and turned into per domain granule. But
until we get this upgraded, this new default is probably
better because I don't think anyone is currently interested in
running a 4KB page size guest with virtio-iommu on a 64KB host.
However supporting 64kB guest on 64kB host with virtio-iommu and
VFIO looks a more important feature.

hw/nvme: add machine compatibility parameter to enable msix exclusive bar

Commit 1901b4967c3f ("hw/block/nvme: move msix table and pba to BAR 0")
moved the MSI-X table and PBA to BAR 0 to make room for enabling CMR and
PMR at the same time. As reported by Julien Grall in #2184, this breaks
migration through system hibernation.

Add a machine compatibility parameter and set it on machines pre 6.0 to
enable the old behavior automatically, restoring the hibernation
migration support.

hw/core/machine: Use qemu_register_resettable for sysbus reset

Move the reset of the sysbus (and thus all devices and buses anywhere
on the qbus tree) from qemu_register_reset() to qemu_register_resettable().

This is a behaviour change: because qemu_register_resettable() is
aware of three-phase reset, this now means that:
* 'enter' phase reset methods of devices and buses are called
before any legacy reset callbacks registered with qemu_register_reset()
* 'exit' phase reset methods of devices and buses are called
after any legacy qemu_register_reset() callbacks

Put another way, a qemu_register_reset() callback is now correctly
ordered in the 'hold' phase along with any other 'hold' phase methods.

The motivation for doing this is that we will now be able to resolve
some reset-ordering issues using the three-phase mechanism, because
the 'exit' phase is always after the 'hold' phase, even when the
'hold' phase function was registered with qemu_register_reset().

machine: Print CPU model name instead of CPU type

The names of supported CPU models instead of CPU types should be
printed when the user specified CPU type isn't supported, to be
consistent with the output from '-cpu ?'.

Correct the error messages to print CPU model names instead of CPU
type names.

machine: Improve is_cpu_type_supported()

It's no sense to check the CPU type when mc->valid_cpu_types[0] is
NULL, which is a program error. Raise an assert on this.

A precise hint for the error message is given when mc->valid_cpu_types[0]
is the only valid entry. Besides, enumeration on mc->valid_cpu_types[0]
when we have mutiple valid entries there is avoided to increase the code
readability, as suggested by Philippe Mathieu-Daudé.

Besides, @cc comes from machine->cpu_type or mc->default_cpu_type. For
the later case, it can be NULL and it's also a program error. We should
use assert() in this case.

machine: Introduce helper is_cpu_type_supported()

The logic, to check if the specified CPU type is supported in
machine_run_board_init(), is independent enough. Factor it out into
helper is_cpu_type_supported(). machine_run_board_init() looks a bit
clean with this. Since we're here, @machine_class is renamed to @mc to
avoid multiple line spanning of code. The comments are tweaked a bit
either.

No functional change intended.
