We need #address-cells properties in all interrupt controllers that are
referred by an interrupt-map [1]. For the RISC-V machine, both PLIC and
APLIC controllers must have this property.
PLIC already sets it in create_fdt_socket_plic(). Set the property for
APLIC in create_fdt_one_aplic().

A HostIOMMUDevice is an abstraction for an assigned device that is protected
by a physical IOMMU (aka host IOMMU). The userspace interaction with this
physical IOMMU can be done either through the VFIO IOMMU type 1 legacy
backend or the new iommufd backend. The assigned device can be a VFIO device
or a VDPA device. The HostIOMMUDevice is needed to interact with the host
IOMMU that protects the assigned device. It is especially useful when the
device is also protected by a virtual IOMMU as this latter use the translation
services of the physical IOMMU and is constrained by it. In that context the
HostIOMMUDevice can be passed to the virtual IOMMU to collect physical IOMMU
capabilities such as the supported address width. In the future, the virtual
IOMMU will use the HostIOMMUDevice to program the guest page tables in the
first translation stage of the physical IOMMU.
Introduce .realize() to initialize HostIOMMUDevice further after instance init.

For some use-cases, it is helpful to have more than one UART
available to the guest. If the second UART slot is not already used
for a TrustZone Secure-World-only UART, create it as a NonSecure UART
only when the user provides a serial backend (e.g. via a second
-serial command line option).
This avoids problems where existing guest software only expects a
single UART, and gets confused by the second UART in the DTB. The
major example of this is older EDK2 firmware, which will send the

Here the code doesn't really care about whether we need to keep that dupfd

keeping the dup_fd around the fdsets may not help that situation so far.

AST2700 dram size calculation is not back compatible AST2600.
According to the DDR capacity hardware behavior,
if users write the data to the address which is beyond the ram size,
it would write the data to the "address % ram_size".
For example:
a. sdram base address "0x4 00000000"
b. sdram size 1 GiB
The available address range is from "0x4 00000000" to "0x4 3FFFFFFF".
If users write 0x12345678 to address "0x5 00000000",
the value of DRAM address 0 (base address 0x4 00000000) will be 0x12345678.
Add aspeed_soc_ast2700_dram_init to calculate the dram size and add
memory I/O whose address range is from "max_ram_size - ram_size" to max_ram_size
and its read/write handler to emulate DDR capacity hardware behavior.

AST2700 interrupt controller(INTC) provides hardware interrupt interfaces
to interrupt of processors PSP, SSP and TSP. In INTC, each interrupt of
INT 128 to INT136 combines 32 interrupts.
Introduce a new aspeed_intc class with instance_init and realize handlers.
So far, this model only supports GICINT128 to GICINT136.
It creates 9 GICINT or-gates to connect 32 interrupts sources
from GICINT128 to GICINT136 as IRQ GPIO-OUTPUT pins.
Then, this model registers IRQ handler with its IRQ GPIO-INPUT pins which
connect to GICINT or-gates. And creates 9 GICINT IRQ GPIO-OUTPUT pins which
connect to GIC device with GIC IRQ 128 to 136.
If one interrupt source from GICINT128 to GICINT136
set irq, the OR-GATE irq callback function is called and set irq to INTC by
OR-GATE GPIO-OUTPUT pins. Then, the INTC irq callback function is called and
set irq to GIC by its GICINT IRQ GPIO-OUTPUT pins. Finally, the GIC irq
callback function is called and set irq to CPUs and
CPUs execute Interrupt Service Routine (ISR).

The Aspeed SMC device model use to have a 'sdram_base' property. It
was removed by commit d177892d4a ("aspeed/smc: Remove unused
"sdram-base" property") because previous changes simplified the DMA
transaction model to use an offset in RAM and not the physical
address.
The AST2700 SoC has larger address space (64-bit) and a new register
DMA DRAM Side Address High Part (0x7C) is introduced to deal with the
high bits of the DMA address. To be able to compute the offset of the
DMA transaction, as done on the other SoCs, we will need to know where
the DRAM is mapped in the address space. Re-introduce a "dram-base"
property to hold this value.

Which one should qemu_get_current_aio_context() return when called from

This has subtle effects on functions that use
qemu_get_current_aio_context(). For example, aio_co_reschedule_self()

qemu_get_current_aio_context() does not differentiate these two

When a macOS Hypervisor.framework call fails which is checked by
assert_hvf_ok(), Qemu exits printing the error value, but not the
location
in the code, as regular assert() macro expansions would.
This change turns assert_hvf_ok() into a macro similar to other
assertions, which expands to a call to the corresponding _impl()
function together with information about the expression that failed
the assertion and its location in the code.
Additionally, stringifying the numeric hv_return_t code is factored
into a helper function that can be reused for diagnostics and debugging
outside of assertions.

macOS Hypervisor.framework uses different types for identifying vCPUs, hv_vcpu_t or hv_vcpuid_t, depending on host architecture. They are not just differently named typedefs for the same primitive type, but reference different-width integers.
Instead of using an integer type and casting where necessary, this change introduces a typedef which resolves the active architecture’s hvf typedef. It also removes a now-unnecessary cast.

In SNP, the hashes page designated with a specific metadata entry
published in AmdSev OVMF.
Therefore, if the user enabled kernel hashes (for measured direct boot),
QEMU should prepare the content of hashes table, and during the
processing of the metadata entry it copy the content into the designated
page and encrypt it.
Note that in SNP (unlike SEV and SEV-ES) the measurements is done in
whole 4KB pages. Therefore QEMU zeros the whole page that includes the
hashes table, and fills in the kernel hashes area in that page, and then
encrypts the whole page. The rest of the page is reserved for SEV
launch secrets which are not usable anyway on SNP.
If the user disabled kernel hashes, QEMU pre-validates the kernel hashes
page as a zero page.

Right now QEMU is importing arch/x86/include/uapi/asm/kvm_para.h
because it includes definitions for kvmclock and for KVM CPUID
bits. However, other definitions for KVM hypercall values and return
codes are included in include/uapi/linux/kvm_para.h and they will be
used by SEV-SNP.
To ensure that it is possible to include both <linux/kvm_para.h> and
"standard-headers/asm-x86/kvm_para.h" without conflicts, provide
linux/kvm_para.h as a portable header too, and forward linux-headers/
files to those in include/standard-headers. Note that <linux/kvm_para.h>
will include architecture-specific definitions as well, but
"standard-headers/linux/kvm_para.h" will not because it can be used in
architecture-independent files.
This could easily be extended to other architectures, but right now
they do not need any symbol in their specific kvm_para.h files.

The TCGCPUOps::cpu_exec_halt method is called from cpu_handle_halt()
when the CPU is halted, so that a target CPU emulation can do
anything target-specific it needs to do. (At the moment we only use
this on i386.)
The current specification of the method doesn't allow the target
specific code to do something different if the CPU is about to come
out of the halt state, because cpu_handle_halt() only determines this
after the method has returned. (If the method called cpu_has_work()
itself this would introduce a potential race if an interrupt arrived
between the target's method implementation checking and
cpu_handle_halt() repeating the check.)
Change the definition of the method so that it returns a bool to
tell cpu_handle_halt() whether to stay in halt or not.
We will want this for the Arm target, where FEAT_WFxT wants to do
some work only for the case where the CPU is in halt but about to
leave it.

In this case discard-after-copy does two things:
- discard data in temp.img to save disk space
- avoid further copy-before-write operation in discarded area
Note that we have to declare WRITE permission on source in
copy-before-write filter, for discard to work. Still we can't take it
unconditionally, as it will break normal backup from RO source. So, we
have to add a parameter and pass it thorough bdrv_open flags.

Currently block_copy creates copy_bitmap in source node. But that is in
bad relation with .independent_close=true of copy-before-write filter:
source node may be detached and removed before .bdrv_close() handler
called, which should call block_copy_state_free(), which in turn should
remove copy_bitmap.
That's all not ideal: it would be better if internal bitmap of
block-copy object is not attached to any node. But that is not possible
now.
The simplest solution is just create copy_bitmap in filter node, where
anyway two other bitmaps are created.

Add module_id member in X86CPUTopoIDs.
module_id can be parsed from APIC ID, so also update APIC ID parsing
rule to support module level. With this support, the conversions with
module level between X86CPUTopoIDs, X86CPUTopoInfo and APIC ID are
completed.
module_id can be also generated from cpu topology, and before i386
supports "modules" in smp, the default "modules per die" (modules *
clusters) is only 1, thus the module_id generated in this way is 0,
so that it will not conflict with the module_id generated by APIC ID.

Support module level in i386 cpu topology structure "X86CPUTopoInfo".
Since x86 does not yet support the "modules" parameter in "-smp",
X86CPUTopoInfo.modules_per_die is currently always 1.
Therefore, the module level width in APIC ID, which can be calculated by
"apicid_bitwidth_for_count(topo_info->modules_per_die)", is always 0 for
now, so we can directly add APIC ID related helpers to support module
level parsing.
In addition, update topology structure in test-x86-topo.c.

Currently, QEMU checks the specify number of topology domains to detect
if there's extended topology levels (e.g., checking nr_dies).
With this bitmap, the extended CPU topology (the levels other than SMT,
core and package) could be easier to detect without touching the
topology details.
This is also in preparation for the follow-up to decouple CPUID[0x1F]
subleaf with specific topology level.

In the -bios case the "isa-bios" memory region is an alias to the BIOS mapped
to the top of the 4G memory boundary. Do the same in the -pflash case, but only
for new machine versions for migration compatibility. This establishes common
behavior and makes pflash commands work in the "isa-bios" region which some
real-world legacy bioses rely on.
Note that in the sev_enabled() case, the "isa-bios" memory region in the -pflash
case will now also point to encrypted memory, just like it already does in the
-bios case.

This commit introduces utility functions for the creation and deallocation
of QemuDmaBuf instances. Additionally, it updates all relevant sections
of the codebase to utilize these new utility functions.
v7: remove prefix, "dpy_gl_" from all helpers
qemu_dmabuf_free() returns without doing anything if input is null
(Daniel P. Berrangé <berrange@redhat.com>)
call G_DEFINE_AUTOPTR_CLEANUP_FUNC for qemu_dmabuf_free()
(Daniel P. Berrangé <berrange@redhat.com>)
v8: Introduction of helpers was removed as those were already added
by the previous commit
v9: set dmabuf->allow_fences to 'true' when dmabuf is created in
virtio_gpu_create_dmabuf()/virtio-gpu-udmabuf.c
removed unnecessary spaces were accidently added in the patch,
'ui/console: Use qemu_dmabuf_new() a...'
v11: Calling qemu_dmabuf_close was removed as closing dmabuf->fd will be
done in qemu_dmabuf_free anyway.
(Daniel P. Berrangé <berrange@redhat.com>)
v12: --- Calling qemu_dmabuf_close separately as qemu_dmabuf_free doesn't
do it.
--- 'dmabuf' is now allocated space so it should be freed at the end of
dbus_scanout_texture
v13: --- Immediately free dmabuf after it is released to prevent possible
leaking of the ptr
(Marc-André Lureau <marcandre.lureau@redhat.com>)
--- Use g_autoptr macro to define *dmabuf for auto clean up instead of
calling qemu_dmabuf_free
(Marc-André Lureau <marcandre.lureau@redhat.com>)
v14: --- (vhost-user-gpu) Change qemu_dmabuf_free back to g_clear_pointer
as it was done because of some misunderstanding (v13).
--- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL
to prevent freed dmabuf to be accessed again in case if(fd==-1)break;
happens (before new dmabuf is allocated). Otherwise, it would cause
invalid memory access when the same function is executed. Also NULL
check should be done before qemu_dmabuf_close (it asserts dmabuf!=NULL.).

New header and source files are added for containing QemuDmaBuf struct
definition and newly introduced helpers for creating/freeing the struct
and accessing its data.
v10: Change the license type for both dmabuf.h and dmabuf.c from MIT to
GPL to be in line with QEMU's default license
v11: -- Added new helpers, qemu_dmabuf_close for closing dmabuf->fd,
qemu_dmabuf_dup_fd for duplicating dmabuf->fd
(Daniel P. Berrangé <berrange@redhat.com>)
-- Let qemu_dmabuf_fee to call qemu_dmabuf_close before freeing
the struct to make sure fd is closed.
(Daniel P. Berrangé <berrange@redhat.com>)
v12: Not closing fd in qemu_dmabuf_free because there are cases fd
should still be available even after the struct is destroyed
(e.g. virtio-gpu: res->dmabuf_fd).

Now that we dropped support for CentOS 8 and Ubuntu 20.04, we can
look into bumping the glib version to a new minimum for further
clean-ups. According to repology.org, available versions are:
CentOS Stream 9: 2.66.7
Debian 11: 2.66.8
Fedora 38: 2.74.1
Freebsd: 2.78.4
Homebrew: 2.80.0
Openbsd: 2.78.4
OpenSuse leap 15.5: 2.70.5
pkgsrc_current: 2.78.4
Ubuntu 22.04: 2.72.1
Thus it should be safe to bump the minimum glib version to 2.66 now.
Version 2.66 comes with new functions for URI parsing which will
allow further clean-ups in the following patches.

qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c

to hw/i386, so that 1) it is available even if no RTC device exist

It is okay to register legacy backends in the middle of xen_bus_init().
All that the registration does is record the existence of the backend
in xenstore.
This makes it possible to remove them from the build without introducing

backend_register callback, whose only purpose is to avoid registering

The function is inspired by pc_isa_bios_init() and should eventually replace it.
Using x86_isa_bios_init() rather than pc_isa_bios_init() fixes pflash commands
to work in the isa-bios region.
While at it convert the magic number 0x100000 (== 1MiB) to increase readability.

Instead of using a single global bounce buffer, give each AddressSpace
its own bounce buffer. The MapClient callback mechanism moves to
AddressSpace accordingly.
This is in preparation for generalizing bounce buffer handling further
to allow multiple bounce buffers, with a total allocation limit

Avoids an explicit use of sizeof(). The GLib allocation macros
ensure that the multiplication by the size of the element
uses the right type and does not overflow.
While at it, change bitmap_new() to use g_new0 directly. Its current
impl of calling bitmap_try_new() followed by a plain abort() has
worse diagnostics than g_new0, which uses g_error to report the actual
allocation size that failed.
