Remove the lm832x keyboard-and-pwm i2c device model. This
was only used by the n800 and n810 machines.
(Although this is an i2c device and so in theory available to create
on the command line, in practice it has an outbound IRQ line that the
machine model needs to wire up, and the only way to inject keys events
into it is to call the lm832x_key_event() function, so it isn't
in practice possible to use it separately from the n800/n810.)

The enable bits in the EXT_CSD_PART_CONFIG ext_csd register do *not*
specify whether the boot partitions exist, but whether they are enabled
for booting. Existence of the boot partitions is specified by a
EXT_CSD_BOOT_MULT != 0.
Currently, in the case of boot-partition-size=1M and boot-config=0,
Linux detects boot partitions of 1M. But as sd_bootpart_offset always
returns 0, all reads/writes are mapped to the same offset in the backing
file.
Fix this bug by calculating the offset independent of which partition is
enabled for booting.
This bug is unlikely to affect many users with QEMU's current set of
boards, because only aspeed sets boot-partition-size, and it also
sets boot-config to 8. So to run into this a user would have to
manually mark the boot partition non-booting from within the guest.

Before, the virtio-mem device would unplug all the memory with any reset
of the device, including during the wake-up of the guest from a
suspended state. Due to this, the virtio-mem driver in the Linux kernel
disallowed suspend-to-ram requests in the guest when the
VIRTIO_MEM_F_PERSISTENT_SUSPEND feature is not exposed by QEMU.
This patch adds the code to skip the reset on wake-up and exposes
theVIRTIO_MEM_F_PERSISTENT_SUSPEND feature to the guest kernel driver
when suspending is possible in QEMU (currently only x86).

LegacyReset does not pass ResetType to the reset callback method, which
the new Resettable framework uses. Due to this, virtio-mem cannot use
the new RESET_TYPE_WAKEUP to skip the reset during wake-up from a
suspended state.
This patch adds overrides Resettable interface methods in VirtIOMEMClass
to use the new Resettable framework and replaces
qemu_[un]register_reset() calls with qemu_[un]register_resettable().

Currently, both qemu_devices_reset() and MachineClass::reset() use
ShutdownCause for the reason of the reset. However, the Resettable
interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.
This patch moves this translation up in the call stack to
qemu_system_reset() and updates all MachineClass children to use the
ResetType instead.

Virtio memory devices rely on PCI BARs to expose the contents of memory.
Because of this they cannot be used (yet) with virtio-mmio or virtio-ccw.
In fact the code that is common to virtio-mem and virtio-pmem, which
is in hw/virtio/virtio-md-pci.c, is only included if CONFIG_VIRTIO_PCI
is set. Reproduce the same condition in the Kconfig file, only allowing
VIRTIO_MEM and VIRTIO_PMEM to be defined if the transport supports it.
Without this patch it is possible to create a configuration with
CONFIG_VIRTIO_PCI=n and CONFIG_VIRTIO_MEM=y, but that causes a
linking failure.

The stolen memory is required for the GOP (EFI) driver and the Windows
driver. While the GOP driver seems to work with any stolen memory size,
the Windows driver will crash if the size doesn't match the size
allocated by the host BIOS. For that reason, it doesn't make sense to
overwrite the stolen memory size. It's true that this wastes some VM
memory. In the worst case, the stolen memory can take up more than a GB.
However, that's uncommon. Additionally, it's likely that a bunch of RAM

The BDSM register is mirrored into MMIO space at least for gen 11 and
later devices. Unfortunately, the Windows driver reads the register
value from MMIO space instead of PCI config space for those devices [1].
Therefore, we either have to keep a 1:1 mapping for the host and guest
address or we have to emulate the MMIO register too. Using the igd in
legacy mode is already hard due to it's many constraints. Keeping a 1:1
mapping may not work in all cases and makes it even harder to use. An
MMIO emulation has to trap the whole MMIO page. This makes accesses to
this page slower compared to using second level address translation.
Nevertheless, it doesn't have any constraints and I haven't noticed any
performance degradation yet making it a better solution.

devices identified by our igd_gen function do support legacy mode. This
won't change when adding our new devices of gen 11 and 12. Therefore, it
makes more sense to accept legacy mode for all known devices instead of
maintaining a long list of known good generations. If we add a new
generation to igd_gen which doesn't support legacy mode for some reason,
it'll be easy to advance the check to reject legacy mode for this

Intel changes it's specification quite often e.g. the location and size

causes our emulation to fail on those devices. So, it's impossible for

Coverity warns that this means that we could end up treating it as a

We only use this in printing the value in the tracepoint, so
mishandling it as a negative number would be harmless, but it's
better to use the right type in the tracepoint. Use uint64_t to

On GICv2 and later, level triggered interrupts are pending when either
the interrupt line is asserted or the interrupt was made pending by a
GICD_ISPENDRn write. Making a level triggered interrupt pending by
software persists until either the interrupt is acknowledged or cleared
by writing GICD_ICPENDRn. As long as the interrupt line is asserted,
the interrupt is pending in any case.
This logic is transparently implemented in gic_test_pending() for
GICv1 and GICv2. The function combines the "pending" irq_state flag
(used for edge triggered interrupts and software requests) and the
line status (tracked in the "level" field). However, we also
incorrectly set the pending flag on a guest write to GICD_ISENABLERn
if the line of a level triggered interrupt was asserted. This keeps
the interrupt pending even if the line is de-asserted after some
time.
This incorrect logic is a leftover of the initial 11MPCore GIC
implementation. That handles things slightly differently to the
architected GICv1 and GICv2. The 11MPCore TRM does not give a lot of
detail on the corner cases of its GIC's behaviour, and historically
we have not wanted to investigate exactly what it does in reality, so
QEMU's GIC model takes the approach of "retain our existing behaviour
for 11MPCore, and implement the architectural standard for later GIC
revisions".
On that basis, commit 8d999995e4 in 2013 is where we added the
"level-triggered interrupt with the line asserted" handling to
gic_test_pending(), and we deliberately kept the old behaviour of
gic_test_pending() for REV_11MPCORE. That commit should have added
the "only if 11MPCore" condition to the setting of the pending bit on
writes to GICD_ISENABLERn, but forgot it.
Add the missing "if REV_11MPCORE" condition, so that our behaviour
on GICv1 and GICv2 matches the GIC architecture requirements.

The read index should not be changed when storing a new message into the
RX or TX FIFO. Changing it at this point will cause the reader to get
out of sync. The wrapping of the read index is already handled by the
pre-write functions for the FIFO status registers anyway.
Additionally, the calculation for wrapping the store index was off by
one, which caused new messages to be written to the wrong location in
the FIFO. This caused incorrect messages to be delivered.

This patch's main focus is to use the previously added
hvf_get_physical_address_range to inform VM creation
about the IPA size we need for the VM, so we can extend
the default 36b IPA size and support VMs with 64+GB of
RAM. This is done by freezing the memory map, computing
the highest GPA and then (depending on if the platform
supports an IPA size that large) telling the kernel to
use a size >= for the VM. In pursuit of this a couple of
things related to how we handle the physical address range
we expose to guests were altered, but for an explanation of
what we were doing:
Today, to get the IPA size we were reading id_aa64mmfr0_el1's
PARange field from a newly made vcpu. Unfortunately, HVF just
returns the hosts PARange directly for the initial value and
not the IPA size that will actually back the VM, so we believe
we have much more address space than we actually do today it seems.
Starting in macOS 13.0 some APIs were introduced to be able to
query the maximum IPA size the kernel supports, and to set the IPA
size for a given VM. However, this still has a couple of issues
on < macOS 15. Up until macOS 15 (and if the hardware supported
it) the max IPA size was 39 bits which is not a valid PARange
value, so we can't clamp down what we advertise in the vcpu's
id_aa64mmfr0_el1 to our IPA size. Starting in macOS 15 however,
the maximum IPA size is 40 bits (if it's supported in the hardware
as well) which is also a valid PARange value so we can set our IPA
size to the maximum as well as clamp down the PARange we advertise
to the guest. This allows VMs with 64+ GB of RAM and should fix the
oddness of the PARange situation as well.

This addition will be necessary for some HVF related work to follow.
For HVF on ARM there exists a set of APIs in macOS 13 to be able to
adjust the IPA size for a given VM. This is useful as by default HVF
uses 36 bits as the IPA size, so to support guests with > 64GB of RAM
we'll need to reach for this.
To have all the info necessary to carry this out however, we need some
plumbing to be able to grab the memory map and compute the highest GPA
prior to creating the VM. This is almost exactly like what kvm_type is
used for on ARM today, and is also what this will be used for. We will
compute the highest GPA and find what IPA size we'd need to satisfy this,
and if it's valid (macOS today caps at 40b) we'll set this to be the IPA
size in coming patches. This new method is only needed (today at least)
on ARM, and obviously only for HVF/macOS, so admittedly it is much less
generic than kvm_type today, but it seemed a somewhat sane way to get
the information we need from the memmap at VM creation time.

We used to need the transitional_function machinery to handle bus
classes and device classes which still used their legacy reset
handling. We have now converted all bus classes to three phase
reset, and simplified the device class legacy reset so it is just an
adapting wrapper function around registration of a hold phase method.
There are therefore no more users of the transitional_function

Now that all devices which still implement a the legacy reset method
register it via device_class_legacy_reset(), we can simplify the
handling of these devices. Instead of using the complex
Resettable::get_transitional_function machinery, we register a hold
phase method which invokes the DeviceClass::legacy_reset method.
This will allow us to remove all the get_transitional_function

Currently we have transitional machinery between legacy reset
and three phase reset that works in two directions:
* if you invoke three phase reset on a device which has set
the DeviceClass::legacy_reset method, we detect this in
device_get_transitional_reset() and arrange that we call
the legacy_reset method during the hold phase of reset
* if you invoke legacy reset on a device which implements
three phase reset, the default legacy_reset method is
device_phases_reset(), which does a three-phase reset
of the device
However, we have now eliminated all the places which could invoke
legacy reset on a device, which means that the function
device_phases_reset() is never called -- it serves only as the value
of DeviceClass::legacy_reset that indicates that the subclass never
overrode the legacy reset method. So we can delete it, and instead
check for legacy_reset != NULL.

* it makes it clearer to the person writing code that

* it makes it easier to rename the reset field (which in turn
makes it easier to find places that call it)
