The driver can query some bits in SMMUv3 IDR5 to learn which
translation granules are supported. Arm recommends that SMMUv3
implementations support at least 4K and 64K granules. But in
the vSMMUv3, there seems to be no reason not to support 16K
translation granule. In addition, if 16K is not supported,
vSVA will failed to be enabled in the future for 16K guest
kernel. So it'd better to support it.

SSE-300 currently shares the SSE-200 Property array. This is
bad principally because the default values of the CPU0_FPU
and CPU0_DSP properties disable the FPU and DSP on the CPU.
That is correct for the SSE-200 but not the SSE-300.
Give the SSE-300 its own Property array with the correct
SSE-300 specific settings:
* SSE-300 has only one CPU, so no CPU1* properties
* SSE-300 CPU has FPU and DSP

Each board in mps2-tz.c specifies a RAMInfo[] array providing
information about each RAM in the board. The .mpc field of the
RAMInfo struct specifies which MPC, if any, the RAM is attached to.
We already assert if the array doesn't have any entry for an MPC, but
we don't diagnose the error of using the same MPC number twice (which
is quite easy to do by accident if copy-and-pasting structure
entries).
Enhance find_raminfo_for_mpc() so that it detects multiple entries
for the MPC as well as missing entries.

The AN524 has three MPCs: one for the BRAM, one for the QSPI flash,
and one for the DDR. We incorrectly set the .mpc field in the
RAMInfo struct for the SRAM block to 1, giving it the same MPC we are
using for the QSPI. The effect of this was that the QSPI didn't get
mapped into the system address space at all, via an MPC or otherwise,
and guest programs which tried to read from the QSPI would get a bus
error. Correct the SRAM RAMInfo to indicate that it does not have an
associated MPC.

In emulation of the CFGI_STE_RANGE command, we now take StreamID as the
start of the invalidation range, regardless of whatever the Range is,
whilst the spec clearly states that
- "Invalidation is performed for an *aligned* range of 2^(Range+1)
StreamIDs."
- "The bottom Range+1 bits of the StreamID parameter are IGNORED,
aligning the range to its size."
Take CFGI_ALL (where Range == 31) as an example, if there are some random
bits in the StreamID field, we'll fail to perform the full invalidation but
get a strange range (e.g., SMMUSIDRange={.start=1, .end=0}) instead. Rework
the emulation a bit to get rid of the discrepancy with the spec.

The virt machine device plug callback currently calls
platform_bus_link_device() for any sysbus device. This is overly
broad, because platform_bus_link_device() will unconditionally grab
the IRQs and MMIOs of the device it is passed, whether it was
intended for the platform bus or not. Restrict hotpluggability of
sysbus devices to only those devices on the dynamic sysbus
allowlist.
We were mostly getting away with this because the board creates the
platform bus as the last device it creates, and so the hotplug
callback did not do anything for all the sysbus devices created by
the board itself. However if the user plugged in a device which
itself uses a sysbus device internally we would have mishandled this
and probably asserted.

The resizeable memory region / RAMBlock that is created for the cmd blob
has a maximum size of whole host pages (e.g., 4k), because RAMBlocks
work on full host pages. In addition, in i386 ACPI code:
acpi_align_size(tables->linker->cmd_blob, ACPI_BUILD_ALIGN_SIZE);
makes sure to align to multiples of 4k, padding with 0.
For example, if our cmd_blob is created with a size of 2k, the maximum
size is 4k - we cannot grow beyond that. Growing might be required
due to guest action when rebuilding the tables, but also on incoming
migration.
This automatic generation of the maximum size used to be sufficient,
however, there are cases where we cross host pages now when growing at
runtime: we exceed the maximum size of the RAMBlock and can crash QEMU when
trying to resize the resizeable memory region / RAMBlock:
$ build/qemu-system-x86_64 --enable-kvm \
-machine q35,nvdimm=on \
-smp 1 \
-cpu host \
-m size=2G,slots=8,maxmem=4G \
-object memory-backend-file,id=mem0,mem-path=/tmp/nvdimm,size=256M \
-device nvdimm,label-size=131072,memdev=mem0,id=nvdimm0,slot=1 \
-nodefaults \
-device vmgenid \
-device intel-iommu
Results in:
Unexpected error in qemu_ram_resize() at ../softmmu/physmem.c:1850:
qemu-system-x86_64: Size too large: /rom@etc/table-loader:
0x2000 > 0x1000: Invalid argument
In this configuration, we consume exactly 4k (32 entries, 128 bytes each)
when creating the VM. However, once the guest boots up and maps the MCFG,
we also create the MCFG table and end up consuming 2 additional entries
(pointer + checksum) -- which is where we try resizing the memory region
/ RAMBlock, however, the maximum size does not allow for it.
Currently, we get the following maximum sizes for our different
mutable tables based on behavior of resizeable RAMBlock:
hw table max_size
------- ---------------------------------------------------------
virt "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
virt "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
virt "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
i386 "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
i386 "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
i386 "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
microvm "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
microvm "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
microvm "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
Let's set the maximum table size for "etc/table-loader" to 64k, so we
can properly grow at runtime, which should be good enough for the future.
Migration is not concerned with the maximum size of a RAMBlock, only
with the used size - so existing setups are not affected. Of course, we
cannot migrate a VM that would have crash when started on older QEMU from
new QEMU to older QEMU without failing early on the destination when
synchronizing the RAM state:
qemu-system-x86_64: Size too large: /rom@etc/table-loader: 0x2000 > 0x1000: Invalid argument
qemu-system-x86_64: error while loading state for instance 0x0 of device 'ram'
qemu-system-x86_64: load of migration failed: Invalid argument
We'll refactor the code next, to make sure we get rid of this implicit
behavior for "etc/acpi/rsdp" as well and to make the code easier to
grasp.

The virt machine already checks KVM_CAP_ARM_VM_IPA_SIZE to get the
upper bound of the IPA size. If that bound is lower than the highest
possible GPA for the machine, then QEMU will error out. However, the
IPA is set to 40 when the highest GPA is less than or equal to 40,
even when KVM may support an IPA limit as low as 32. This means KVM
may fail the VM creation unnecessarily. Additionally, 40 is selected
with the value 0, which means use the default, and that gets around
a check in some versions of KVM, causing a difficult to debug fail.
Always use the IPA size that corresponds to the highest possible GPA,
unless it's lower than 32, in which case use 32. Also, we must still
use 0 when KVM only supports the legacy fixed 40 bit IPA.

As of today, the driver can invalidate a number of pages that is
not a power of 2. However IOTLB unmap notifications and internal
IOTLB invalidations work with masks leading to erroneous
invalidations.
In case the range is not a power of 2, split invalidations into
power of 2 invalidations.
When looking for a single page entry in the vSMMU internal IOTLB,
let's make sure that if the entry is not found using a
g_hash_table_remove() we iterate over all the entries to find a
potential range that overlaps it.

Keyboard-Controller-Style devices for IPMI purposes are exposed via LPC
IO cycles from the BMC to the host.
Expose support on the BMC side by implementing the usual MMIO
behaviours, and expose the ability to inspect the KCS registers in
"host" style by accessing QOM properties associated with each register.
The model caters to the IRQ style of both the AST2600 and the earlier
SoCs (AST2400 and AST2500). The AST2600 allocates an IRQ for each LPC
sub-device, while there is a single IRQ shared across all subdevices on
the AST2400 and AST2500.

that have PSCI enabled, as Linux fails to find PSCI in the device tree

Note that the main watchdog (unlike the s32k watchdog) in the SSE-300
is a different device from the CMSDK watchdog; we don't have a model

We model Arm "Subsystems for Embedded" SoC subsystems using generic
code which is split into various sub-devices which are configurable
by QOM properties to handle the behaviour differences between the SSE
subsystems we implement. Currently the only sub-device which needs
to change is the IOTKIT_SYSCTL device, and we do this with a mix of
properties that directly specify divergent behaviours (eg
CPUWAIT_RST) and passing it the SYS_VERSION register value as a way
for it to distinguish IoTKit from SSE-200.
The "pass SYS_VERSION" approach is already a bit hacky, since the
IOTKIT_SYSCTL device has to know that the different part of the
register value happens to be bits [31:28]. For SSE-300 this register
is renamed SOC_IDENTITY and has a different format entirely, all of
whose fields can be configured by the SoC integrator when they
integrate the SSE into their SoC, and so "pass SYS_VERSION" breaks
down completely.
Switch to using a simple integer property representing an
internal-to-QEMU enumeration of the SSE flavour. For the moment we
only need this in IOTKIT_SYSCTL, but as we add SSE-300 support a few
of the other devices will also need to know.
We define and permit a value for the SSE-300 so we can start using
it in subsequent commits which add SSE-300 support.
The now-redundant is_sse200 flag in IoTKitSysCtl will be removed
in the following commit.

On the MPS2 boards, the first 32 interrupt lines are entirely
internal to the SSE; interrupt lines for devices outside the SSE
start at 32. In the application notes that document each FPGA image,
the interrupt wiring is documented from the point of view of the CPU,
so '0' is the first of the SSE's interrupts and the devices in the
FPGA image itself are '32' and up: so the UART 0 Receive interrupt is
32, the SPI #0 interrupt is 51, and so on.
Within our implementation, because the external interrupts must be
connected to the EXP_IRQ[0...n] lines of the SSE object, we made the
get_sse_irq_in() function take an irqno whose values start at 0 for
the first FPGA device interrupt. In this numbering scheme the UART 0
Receive interrupt is 0, the SPI #0 interrupt is 19, and so on.
The result of these two different numbering schemes has been that
half of the devices were wired up to the wrong IRQs: the UART IRQs
are wired up correctly, but the DMA and SPI devices were passing
start-at-32 values to get_sse_irq_in() and so being mis-connected.
Fix the bug by making get_sse_irq_in() take values specified with the
same scheme that the hardware manuals use, to avoid confusion.
