qapi/qom: Define cache enumeration and properties for machine
The x86 and ARM need to allow user to configure cache properties
(current only topology):
* For x86, the default cache topology model (of max/host CPU) does not
always match the Host's real physical cache topology. Performance can
increase when the configured virtual topology is closer to the
physical topology than a default topology would be.
* For ARM, QEMU can't get the cache topology information from the CPU
registers, then user configuration is necessary. Additionally, the
cache information is also needed for MPAM emulation (for TCG) to
build the right PPTT.
Define smp-cache related enumeration and properties in QAPI, so that
user could configure cache properties for SMP system through -machine in
the subsequent patch.
Cache enumeration (CacheLevelAndType) is implemented as the combination
of cache level (level 1/2/3) and cache type (data/instruction/unified).
Currently, separated L1 cache (L1 data cache and L1 instruction cache)
with unified higher-level cache (e.g., unified L2 and L3 caches), is the
most common cache architectures.
Therefore, enumerate the L1 D-cache, L1 I-cache, L2 cache and L3 cache
with smp-cache object to add the basic cache topology support. Other
kinds of caches (e.g., L1 unified or L2/L3 separated caches) can be
added directly into CacheLevelAndType if necessary.
Cache properties (SmpCacheProperties) currently only contains cache
topology information, and other cache properties can be added in it
if necessary.
Note, define cache topology based on CPU topology level with two
reasons:
1. In practice, a cache will always be bound to the CPU container
(either private in the CPU container or shared among multiple
containers), and CPU container is often expressed in terms of CPU
topology level.
2. The x86's cache-related CPUIDs encode cache topology based on APIC
ID's CPU topology layout. And the ACPI PPTT table that ARM/RISCV
relies on also requires CPU containers to help indicate the private
shared hierarchy of the cache. Therefore, for SMP systems, it is
natural to use the CPU topology hierarchy directly in QEMU to define
the cache topology.
With smp-cache QAPI support, add smp cache topology for machine by
parsing the smp-cache object list.
Also add the helper to access/update cache topology level of machine.

pcie: enable Extended tag field support
>From what I read PCI has 32 transactions, PCI Express devices can handle
256 with Extended tag enabled (spec mentions also larger values but I
lack PCIe knowledge).
QEMU leaves 'Extended tag field' with 0 as value:
Capabilities: [e0] Express (v1) Root Complex Integrated Endpoint, IntMsgNum 0
DevCap: MaxPayload 128 bytes, PhantFunc 0
ExtTag- RBE+ FLReset- TEE-IO-
SBSA ACS has test 824 which checks for PCIe device capabilities. BSA
specification [1] (SBSA is on top of BSA) in section F.3.2 lists
expected values for Device Capabilities Register:
Device Capabilities Register Requirement
Role based error reporting RCEC and RCiEP: Hardwired to 1
Endpoint L0s acceptable latency RCEC and RCiEP: Hardwired to 0
L1 acceptable latency RCEC and RCiEP: Hardwired to 0
Captured slot power limit scale RCEC and RCiEP: Hardwired to 0
Captured slot power limit value RCEC and RCiEP: Hardwired to 0
Max payload size value must be compliant with PCIe spec
Phantom functions RCEC and RCiEP: Recommendation is to
hardwire this bit to 0.
Extended tag field Hardwired to 1
1. https://developer.arm.com/documentation/den0094/c/
This change enables Extended tag field. All versioned platforms should
have it disabled for older versions (tested with Arm/virt).

smbios: make memory device size configurable per Machine
Currently QEMU describes initial[1] RAM* in SMBIOS as a series of virtual DIMMs (capped at 16Gb max) using type 17 structure entries. Which is fine for the most cases. However when starting guest with terabytes of RAM this leads to too many memory device structures, which eventually upsets linux kernel as it reserves only 64K for these entries and when that border is crossed out it runs out of reserved memory. Instead of partitioning initial RAM on 16Gb DIMMs, use maximum possible chunk size that SMBIOS spec allows[2]. Which lets encode RAM in lower 31 bits of 32bit field (which amounts upto 2047Tb per DIMM). As result initial RAM will generate only one type 17 structure until host/guest reach ability to use more RAM in the future. Compat changes: We can't unconditionally change chunk size as it will break QEMU<->guest ABI (and migration). Thus introduce a new machine class field that would let older versioned machines to use legacy 16Gb chunks, while new(er) machine type[s] use maximum possible chunk size. PS: While it might seem to be risky to rise max entry size this large (much beyond of what current physical RAM modules support), I'd not expect it causing much issues, modulo uncovering bugs in software running within guest. And those should be fixed on guest side to handle SMBIOS spec properly, especially if guest is expected to support so huge RAM configs. In worst case, QEMU can reduce chunk size later if we would care enough about introducing a workaround for some 'unfixable' guest OS, either by fixing up the next machine type or giving users a CLI option to customize it. 1) Initial RAM - is RAM configured with help '-m SIZE' CLI option/ implicitly defined by machine. It doesn't include memory configured with help of '-device' option[s] (pcdimm,nvdimm,...) 2) SMBIOS 3.1.0 7.18.5 Memory Device — Extended Size PS: * tested on 8Tb host with RHEL6 guest, which seems to parse type 17 SMBIOS table entries correctly (according to 'dmidecode').

hw: Fix crash that happens when introspecting scsi-block on older machine types
"make check SPEED=slow" is currently failing the device-introspect-test on
older machine types since introspecting "scsi-block" is causing an abort:
$ ./qemu-system-x86_64 -M pc-q35-8.0 -monitor stdio
QEMU 9.0.50 monitor - type 'help' for more information
(qemu) device_add scsi-block,help
Unexpected error in object_property_find_err() at
../../devel/qemu/qom/object.c:1357:
can't apply global scsi-disk-base.migrate-emulated-scsi-request=false:
Property 'scsi-block.migrate-emulated-scsi-request' not found
Aborted (core dumped)
The problem is that the compat code tries to change the
"migrate-emulated-scsi-request" property for all devices that are
derived from "scsi-block", but the property has only been added
to "scsi-hd" and "scsi-cd" via the DEFINE_SCSI_DISK_PROPERTIES macro.
Thus let's fix the problem by only changing the property on the devices
that really have this property.
Fixes:

virtio-pci: implement No_Soft_Reset bit
In current code, when guest does S3, virtio-gpu are reset due to the bit No_Soft_Reset is not set. After resetting, the display resources of virtio-gpu are destroyed, then the display can't come back and only show blank after resuming. Implement No_Soft_Reset bit of PCI_PM_CTRL register, then guest can check this bit, if this bit is set, the devices resetting will not be done, and then the display can work after resuming. No_Soft_Reset bit is implemented for all virtio devices, and was tested only on virtio-gpu device. Set it false by default for safety.

scsi-disk: Fix crash for VM configured with USB CDROM after live migration
For VMs configured with the USB CDROM device:
-drive file=/path/to/local/file,id=drive-usb-disk0,media=cdrom,readonly=on...
-device usb-storage,drive=drive-usb-disk0,id=usb-disk0...
QEMU process may crash after live migration, to reproduce the issue,
configure VM (Guest OS ubuntu 20.04 or 21.10) with the following XML:
<disk type='file' device='cdrom'>
<driver name='qemu' type='raw'/>
<source file='/path/to/share_fs/cdrom.iso'/>
<target dev='sda' bus='usb'/>
<readonly/>
<address type='usb' bus='0' port='2'/>
</disk>
<controller type='usb' index='0' model='piix3-uhci'/>
Do the live migration repeatedly, crash may happen after live migratoin,
trace log at the source before live migration is as follows:

When designing the USB mass storage device model, QEMU places SCSI disk
device as the backend of USB mass storage device. In addition, USB mass
device driver in Guest OS conforms to the "Universal Serial Bus Mass
Storage Class Bulk-Only Transport" specification in order to simulate
the transform behavior between a USB controller and a USB mass device.
The following shows the protocol hierarchy:
+----------------+
CDROM driver | scsi command | CDROM
+----------------+
+-----------------------+
USB mass | USB Mass Storage Class| USB mass
storage driver | Bulk-Only Transport | storage device
+-----------------------+
+----------------+
USB Controller | USB Protocol | USB device
+----------------+
In the USB protocol layer, between the USB controller and USB device, at
least two USB packets will be transformed when guest OS send a
read operation to USB mass storage device:
1. The CBW packet, which will be delivered to the USB device's Bulk-Out
endpoint. In order to simulate a read operation, the USB mass storage
device parses the CBW and converts it to a SCSI command, which would be
executed by CDROM(represented as SCSI disk in QEMU internally), and store
the result data of the SCSI command in a buffer.
2. The DATA-IN packet, which will be delivered from the USB device's
Bulk-In endpoint(fetched directly from the preceding buffer) to the USB
controller.
We consider UHCI to be the controller. The two packets mentioned above may
have been processed by UHCI in two separate frame entries of the Frame List
, and also described by two different TDs. Unlike the physical environment,
a virtualized environment requires the QEMU to make sure that the result
data of CBW is not lost and is delivered to the UHCI controller.
Currently, these types of SCSI requests are not migrated, so QEMU cannot
ensure the result data of the IO operation is not lost if there are
inflight emulated SCSI requests during the live migration.
Assume for the moment that the USB mass storage device is processing the
CBW and storing the result data of the read operation to a buffre, live
migration happens and moves the VM to the destination while not migrating
the result data of the read operation.
After migration, when UHCI at the destination issues a DATA-IN request to
the USB mass storage device, a crash happens because USB mass storage device
fetches the result data and get nothing.
The scenario this patch addresses is this one.
Theoretically, any device that uses the SCSI disk as a back-end would be
affected by this issue. In this case, it is the USB CDROM.
To fix it, inflight emulated SCSI request be migrated during live migration,
similar to the DMA SCSI request.

vfio/pci: migration: Skip config space check for Vendor Specific Information in VSC during restore/load
In case of migration, during restore operation, qemu checks config space of the pci device with the config space in the migration stream captured during save operation. In case of config space data mismatch, restore operation is failed. config space check is done in function get_pci_config_device(). By default VSC (vendor-specific-capability) in config space is checked. Due to qemu's config space check for VSC, live migration is broken across NVIDIA vGPU devices in situation where source and destination host driver is different. In this situation, Vendor Specific Information in VSC varies on the destination to ensure vGPU feature capabilities exposed to the guest driver are compatible with destination host. If a vfio-pci device is migration capable and vfio-pci vendor driver is OK with volatile Vendor Specific Info in VSC then qemu should exempt config space check for Vendor Specific Info. It is vendor driver's responsibility to ensure that VSC is consistent across migration. Here consistency could mean that VSC format should be same on source and destination, however actual Vendor Specific Info may not be byte-to-byte identical. This patch skips the check for Vendor Specific Information in VSC for VFIO-PCI device by clearing pdev->cmask[] offsets. Config space check is still enforced for 3 byte VSC header. If cmask[] is not set for an offset, then qemu skips config space check for that offset. VSC check is skipped for machine types >= 9.1. The check would be enforced on older machine types (<= 9.0).

migration: Remove non-multifd compression
The 'compress' migration capability enables the old compression code
which has shown issues over the years and is thought to be less stable
and tested than the more recent multifd-based compression. The old
compression code has been deprecated in 8.2 and now is time to remove
it.

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/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().

numa: Skip invalidation of cluster and NUMA node boundary for qtest
There are warning messages printed from tests/qtest/numa-test.c,
to complain the CPU cluster and NUMA node boundary is broken. Since
the broken boundary is expected, we don't want to see the warning
messages.

have been associated with node-0 and node-1 respectively. \
It can cause OSes like Linux to misbehave
:

qtest is enabled, to avoid the warning messages.

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 ?'.

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.

machine: Use error handling when CPU type is checked
Functions that use an Error **errp parameter to return errors should not also report them to the user, because reporting is the caller's job. The principle is violated by machine_run_board_init() because it calls error_report(), error_printf(), and exit(1) when the machine doesn't support the requested CPU type. Clean this up by using error_setg() and error_append_hint() instead. No functional change, as the only caller passes &error_fatal.

igb: Add Function Level Reset to PF and VF
The Intel 82576EB GbE Controller say that the Physical and Virtual
Functions support Function Level Reset. Add the capability to the PF
device model using device property "x-pcie-flr-init" which is "on" by
default and "off" for machines <= 8.1 to preserve compatibility.
The FLR capability of the VF model is defined according to the FLR
property of the PF, this to avoid adding an extra compatibility
property.

CPU topology: extend with s390 specifics
S390 adds two new SMP levels, drawers and books to the CPU topology. S390 CPUs have specific topology features like dedication and entitlement. These indicate to the guest information on host vCPU scheduling and help the guest make better scheduling decisions. Add the new levels to the relevant QAPI structs. Add all the supported topology levels, dedication and entitlement as properties to S390 CPUs. Create machine-common.json so we can later include it in machine-target.json also.
