The qemu-common.h header is not supposed to be included from any
other header files, only from .c files (as documented in a comment at
the start of it).
include/hw/i386/x86.h and include/hw/i386/microvm.h break this rule.
In fact, the include is not required at all, so we can just drop it
from both files.

The basic SGX did not enable numa for SGX EPC sections, which
result in all EPC sections located in numa node 0. This patch
enable SGX numa function in the guest and the EPC section can
work with RAM as one numa node.
The Guest kernel related log:
[ 0.009981] ACPI: SRAT: Node 0 PXM 0 [mem 0x180000000-0x183ffffff]
[ 0.009982] ACPI: SRAT: Node 1 PXM 1 [mem 0x184000000-0x185bfffff]
The SRAT table can normally show SGX EPC sections menory info in different
numa nodes.

We're about to support a third vIOMMU for x86, virtio-iommu which
doesn't inherit X86IOMMUState. Move the IOMMU singleton into
PCMachineState, so it can be shared between all three vIOMMUs.
The x86_iommu_get_default() helper is still needed by KVM and IOAPIC to
fetch the default IRQ-remapping IOMMU. Since virtio-iommu doesn't
support IRQ remapping, this interface doesn't need to change for the
moment. We could later replace X86IOMMUState with an "IRQ remapping
IOMMU" interface if necessary.

Add helpers to detect if SGX EPC exists above 4g, and if so, where SGX
EPC above 4g ends. Use the helpers to adjust the device memory range
if SGX EPC exists above 4g.
For multiple virtual EPC sections, we just put them together physically
contiguous for the simplicity because we don't support EPC NUMA affinity
now. Once the SGX EPC NUMA support in the kernel SGX driver, we will
support this in the future.
Note that SGX EPC is currently hardcoded to reside above 4g.

Expose SGX to the guest if and only if KVM is enabled and supports
virtualization of SGX. While the majority of ENCLS can be emulated to
some degree, because SGX uses a hardware-based root of trust, the
attestation aspects of SGX cannot be emulated in software, i.e.
ultimately emulation will fail as software cannot generate a valid
quote/report. The complexity of partially emulating SGX in Qemu far
outweighs the value added, e.g. an SGX specific simulator for userspace
applications can emulate SGX for development and testing purposes.
Note, access to the PROVISIONKEY is not yet advertised to the guest as
KVM blocks access to the PROVISIONKEY by default and requires userspace
to provide additional credentials (via ioctl()) to expose PROVISIONKEY.

Because SGX EPC is enumerated through CPUID, EPC "devices" need to be
realized prior to realizing the vCPUs themselves, i.e. long before
generic devices are parsed and realized. From a virtualization
perspective, the CPUID aspect also means that EPC sections cannot be
hotplugged without paravirtualizing the guest kernel (hardware does
not support hotplugging as EPC sections must be locked down during
pre-boot to provide EPC's security properties).
So even though EPC sections could be realized through the generic
-devices command, they need to be created much earlier for them to
actually be usable by the guest. Place all EPC sections in a
contiguous block, somewhat arbitrarily starting after RAM above 4g.
Ensuring EPC is in a contiguous region simplifies calculations, e.g.
device memory base, PCI hole, etc..., allows dynamic calculation of the
total EPC size, e.g. exposing EPC to guests does not require -maxmem,
and last but not least allows all of EPC to be enumerated in a single
ACPI entry, which is expected by some kernels, e.g. Windows 7 and 8.
The new compound properties command for sgx like below:
......
-object memory-backend-epc,id=mem1,size=28M,prealloc=on \
-object memory-backend-epc,id=mem2,size=10M \
-M sgx-epc.0.memdev=mem1,sgx-epc.1.memdev=mem2

before generic devices are parsed and realized. Because of this,
do not allow 'sgx-epc' devices to be instantiated after vCPUS have
been created.
The 'sgx-epc' device is essentially a placholder at this time, it will
be fully implemented in a future patch along with a dedicated command
to create 'sgx-epc' devices.

EPC (Enclave Page Cahe) is a specialized type of memory used by Intel
SGX (Software Guard Extensions). The SDM desribes EPC as:
The Enclave Page Cache (EPC) is the secure storage used to store
enclave pages when they are a part of an executing enclave. For an
EPC page, hardware performs additional access control checks to
restrict access to the page. After the current page access checks
and translations are performed, the hardware checks that the EPC
page is accessible to the program currently executing. Generally an
EPC page is only accessed by the owner of the executing enclave or
an instruction which is setting up an EPC page.
Because of its unique requirements, Linux manages EPC separately from
normal memory. Similar to memfd, the device /dev/sgx_vepc can be
opened to obtain a file descriptor which can in turn be used to mmap()
EPC memory.

A bus lock is acquired through either split locked access to writeback
(WB) memory or any locked access to non-WB memory. It is typically >1000
cycles slower than an atomic operation within a cache and can also
disrupts performance on other cores.
Virtual Machines can exploit bus locks to degrade the performance of
system. To address this kind of performance DOS attack coming from the
VMs, bus lock VM exit is introduced in KVM and it can report the bus
locks detected in guest. If enabled in KVM, it would exit to the
userspace to let the user enforce throttling policies once bus locks
acquired in VMs.
The availability of bus lock VM exit can be detected through the
KVM_CAP_X86_BUS_LOCK_EXIT. The returned bitmap contains the potential
policies supported by KVM. The field KVM_BUS_LOCK_DETECTION_EXIT in
bitmap is the only supported strategy at present. It indicates that KVM
will exit to userspace to handle the bus locks.
This patch adds a ratelimit on the bus locks acquired in guest as a
mitigation policy.
Introduce a new field "bus_lock_ratelimit" to record the limited speed
of bus locks in the target VM. The user can specify it through the
"bus-lock-ratelimit" as a machine property. In current implementation,
the default value of the speed is 0 per second, which means no
restrictions on the bus locks.
As for ratelimit on detected bus locks, simply set the ratelimit
interval to 1s and restrict the quota of bus lock occurence to the value
of "bus_lock_ratelimit". A potential alternative is to introduce the
time slice as a property which can help the user achieve more precise
control.
The detail of bus lock VM exit can be found in spec:

After fixing the _UID value for the primary PCI root bridge in
af1b80ae it was discovered that this change updates Windows
configuration in an incompatible way causing network configuration
failure unless DHCP is used. More details provided on the list:
https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg08484.html
This change reverts the _UID update from 1 to 0 for q35 and i440fx
VMs before version 5.2 to maintain the original behaviour when
upgrading.

OVMF is developing a mechanism for depositing a GUIDed table just
below the known location of the reset vector. The table goes
backwards in memory so all entries are of the form
<data>|len|<GUID>
Where <data> is arbtrary size and type, <len> is a uint16_t and
describes the entire length of the entry from the beginning of the
data to the end of the guid.
The foot of the table is of this form and <len> for this case
describes the entire size of the table. The table foot GUID is
defined by OVMF as 96b582de-1fb2-45f7-baea-a366c55a082d and if the
table is present this GUID is just below the reset vector, 48 bytes
before the end of the firmware file.
Add a parser for the ovmf reset block which takes a copy of the block,
if the table foot guid is found, minus the footer and a function for
later traversal to return the data area of any specified GUIDs.

Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table name.
Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID
and OEM table ID for the strings "BOCHS" and "BXPC" and if they are
found, the game crashes(this may be an intentional detection
mechanism to prevent playing the game in a virtualized environment).
This patch allows you to override these default values.
The feature can be used in this manner:
qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN
The oem-id string can be up to 6 bytes in size, and the
oem-table-id string can be up to 8 bytes in size. If the string are
smaller than their respective sizes they will be padded with space.
If either of these parameters is not set, the current default values
will be used for the one missing.
Note that the the OEM Table ID field will not be extended with the
name of the table, but will use either the default name or the user
provided one.
This does not affect the -acpitable option (for user-defined ACPI
tables), which has precedence over -machine option.

hw/pci/pci.c:268: int pci_bus_get_irq_level(PCIBus *, int): Assertion `irq_num < bus->nirq' failed.
This is because ich9_lpc_sci_irq() returns -1 for reserved
(illegal) values, but ich9_lpc_pmbase_sci_update() considers
it valid and store it in a 8-bit unsigned type. Then the 255
value is used as GSI IRQ, resulting in a PIRQ value of 247,
more than ICH9_LPC_NB_PIRQS (8).
Fix by simply ignoring the invalid access (and reporting it):
pci_cfg_write ICH9-LPC 31:0 @0x41 <- 0xebed205d
ICH9 LPC: SCI IRQ SEL #3 is reserved
pci_cfg_read mch 00:0 @0x0 -> 0x8086

QEMU's kvmclock device is only created when KVM PV feature bits for
kvmclock (KVM_FEATURE_CLOCKSOURCE/KVM_FEATURE_CLOCKSOURCE2) are
exposed to the guest. With 'kvm=off' cpu flag the device is not
created and we don't call KVM_GET_CLOCK/KVM_SET_CLOCK upon migration.
It was reported that without these call at least Hyper-V TSC page
clocksouce (which can be enabled independently) gets broken after
migration.
Switch to creating kvmclock QEMU device unconditionally, it seems
to always make sense to call KVM_GET_CLOCK/KVM_SET_CLOCK on migration.
Use KVM_CAP_ADJUST_CLOCK check instead of CPUID feature bits.

Uses the existing gpex device which is also used as pcie host bridge on
arm/aarch64. For now only a 32bit mmio window and no ioport support.
It is disabled by default, use "-machine microvm,pcie=on" to enable.
ACPI support must be enabled too because the bus is declared in the
DSDT table.
