We are currently missing the deallocation of the [host_]resv_regions
in case of hot unplug. Also to make things more simple let's rule
out the case where multiple HostIOMMUDevices would be aliased and
attached to the same IOMMUDevice. This allows to remove the handling
of conflicting Host reserved regions. Anyway this is not properly
supported at guest kernel level. On hotunplug the reserved regions
are reset to the ones set by virtio-iommu property.

Now we have switched to PCIIOMMUOps to convey host IOMMU information,
the host reserved regions are transmitted when the PCIe topology is
built. This happens way before the virtio-iommu driver calls the probe
request. So let's remove the probe_done flag that allowed to check
the probe was not done before the IOMMU MR got enabled. Besides this
probe_done flag had a flaw wrt migration since it was not saved/restored.
The only case at risk is if 2 devices were plugged to a
PCIe to PCI bridge and thus aliased. First of all we
discovered in the past this case was not properly supported for
neither SMMU nor virtio-iommu on guest kernel side: see
[RFC] virtio-iommu: Take into account possible aliasing in virtio_iommu_mr()
https://lore.kernel.org/all/20230116124709.793084-1-eric.auger@redhat.com/

sequence would be from a virtio-iommu driver point of view.

This reverts commit 1b889d6e39.
There are different problems with that tentative fix:
- Some resources are left dangling (resv_regions,
host_resv_ranges) and memory subregions are left attached to
the root MR although freed as embedded in the sdev IOMMUDevice.
Finally the sdev->as is not destroyed and associated listeners
are left.
- Even when fixing the above we observe a memory corruption
associated with the deallocation of the IOMMUDevice. This can
be observed when a VFIO device is hotplugged, hot-unplugged
and a system reset is issued. At this stage we have not been
able to identify the root cause (IOMMU MR or as structs beeing
overwritten and used later on?).
- Another issue is HostIOMMUDevice are indexed by non aliased
BDF whereas the IOMMUDevice is indexed by aliased BDF - yes the
current naming is really misleading -. Given the state of the
code I don't think the virtio-iommu device works in non
singleton group case though.
So let's revert the patch for now. This means the IOMMU MR/as survive
the hotunplug. This is what is done in the intel_iommu for instance.
It does not sound very logical to keep those but currently there is
no symetric function to pci_device_iommu_address_space().
probe_done issue will be handled in a subsequent patch. Also
resv_regions and host_resv_regions will be deallocated separately.

notified event by evaluating ACPI _EVT method to know the type of event. Use
ACPI GED to also notify the guest kernel about any CPU hot(un)plug events.
Note, GED interface is used by many hotplug events like memory hotplug, NVDIMM
hotplug and non-hotplug events like system power down event. Each of these can
be selected using a bit in the 32 bit GED IO interface. A bit has been reserved
for the CPU hotplug event.
ACPI CPU hotplug related initialization should only happen if ACPI_CPU_HOTPLUG
support has been enabled for particular architecture. Add cpu_hotplug_hw_init()
stub to avoid compilation break.

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').

in-order starting at vq->used_idx. If the element is valid (filled), the
element is written to the used/descriptor ring. This process continues
until we find an invalid (not filled) element.
For packed VQs, the first entry (at vq->used_idx) is written to the
descriptor ring last so the guest doesn't see any invalid descriptors.
If any elements were written, the used_idx is updated.

Add VIRTIO_F_IN_ORDER feature support for the virtqueue_fill operation.
The goal of the virtqueue_ordered_fill operation when the
VIRTIO_F_IN_ORDER feature has been negotiated is to search for this
now-used element, set its length, and mark the element as filled in
the VirtQueue's used_elems array.
By marking the element as filled, it will indicate that this element has
been processed and is ready to be flushed, so long as the element is
in-order.

When reading input audio in the virtio-snd input callback,
virtio_snd_pcm_in_cb(), we do not check whether the iov can actually fit
the data buffer. This is because we use the buffer->size field as a
total-so-far accumulator instead of byte-size-left like in TX buffers.
This triggers an out of bounds write if the size of the virtio queue
element is equal to virtio_snd_pcm_status, which makes the available
space for audio data zero. This commit adds a check for reaching the
maximum buffer size before attempting any writes.

SMMUv3 OAS is currently hardcoded in the code to 44 bits, for nested
configurations that can be a problem, as stage-2 might be shared with
the CPU which might have different PARANGE, and according to SMMU manual
ARM IHI 0070F.b:
6.3.6 SMMU_IDR5, OAS must match the system physical address size.
This patch doesn't change the SMMU OAS, but refactors the code to
make it easier to do that:
- Rely everywhere on IDR5 for reading OAS instead of using the
SMMU_IDR5_OAS macro, so, it is easier just to change IDR5 and
it propagages correctly.
- Add additional checks when OAS is greater than 48bits.
- Remove unused functions/macros: pa_range/MAX_PA.

Previously, to check if faults are enabled, it was sufficient to check
the current stage of translation and check the corresponding
record_faults flag.
However, with nesting, it is possible for stage-1 (nested) translation
to trigger a stage-2 fault, so we check SMMUPTWEventInfo as it would
have the correct stage set from the page table walk.

With nesting, we would need to invalidate IPAs without
over-invalidating stage-1 IOVAs. This can be done by
distinguishing IPAs in the TLBs by having ASID=-1.
To achieve that, rework the invalidation for IPAs to have a
separate function, while for IOVA invalidation ASID=-1 means
invalidate for all ASIDs.

When nested translation is requested, do the following:
- Translate stage-1 table address IPA into PA through stage-2.
- Translate stage-1 table walk output (IPA) through stage-2.
- Create a single TLB entry from stage-1 and stage-2 translations
using logic introduced before.
smmu_ptw() has a new argument SMMUState which include the TLB as
stage-1 table address can be cached in there.
Also in smmu_ptw(), a separate path used for nesting to simplify the
code, although some logic can be combined.
With nested translation class of translation fault can be different,
from the class of the translation, as faults from translating stage-1
tables are considered as CLASS_TT and not CLASS_IN, a new member
"is_ipa_descriptor" added to "SMMUPTWEventInfo" to differ faults
from walking stage 1 translation table and faults from translating
an IPA for a transaction.

This patch adds support for nested (combined) TLB entries.
The main function combine_tlb() is not used here but in the next
patches, but to simplify the patches it is introduced first.
Main changes:
1) New field added in the SMMUTLBEntry struct: parent_perm, for
nested TLB, holds the stage-2 permission, this can be used to know
the origin of a permission fault from a cached entry as caching
the “and” of the permissions loses this information.
SMMUPTWEventInfo is used to hold information about PTW faults so
the event can be populated, the value of stage used to be set
based on the current stage for TLB permission faults, however
with the parent_perm, it is now set based on which perm has
the missing permission
When nesting is not enabled it has the same value as perm which
doesn't change the logic.
2) As combined TLB implementation is used, the combination logic
chooses:
- tg and level from the entry which has the smallest addr_mask.
- Based on that the iova that would be cached is recalculated.
- Translated_addr is chosen from stage-2.

In the next patch, combine_tlb() will be added which combines 2 TLB
entries into one for nested translations, which chooses the granule
and level from the smallest entry.
This means that with nested translation, an entry can be cached with
the granule of stage-2 and not stage-1.
However, currently, the lookup for an IOVA is done with input stage
granule, which is stage-1 for nested configuration, which will not
work with the above logic.
This patch reworks lookup in that case, so it falls back to stage-2
granule if no entry is found using stage-1 granule.
Also, drop aligning the iova to avoid over-aligning in case the iova
is cached with a smaller granule, the TLB lookup will align the iova
anyway for each granule and level, and the page table walker doesn't
consider the page offset bits.

According to ARM SMMU architecture specification (ARM IHI 0070 F.b),
In "5.2 Stream Table Entry":
[51:6] S1ContextPtr
If Config[1] == 1 (stage 2 enabled), this pointer is an IPA translated by
stage 2 and the programmed value must be within the range of the IAS.
In "5.4.1 CD notes":
The translation table walks performed from TTB0 or TTB1 are always performed
in IPA space if stage 2 translations are enabled.
This patch implements translation of the S1 context descriptor pointer and
TTBx base addresses through the S2 stage (IPA -> PA)
smmuv3_do_translate() is updated to have one arg which is translation
class, this is useful to:
- Decide wether a translation is stage-2 only or use the STE config.
- Populate the class in case of faults, WALK_EABT is left unchanged
for stage-1 as it is always IN, while stage-2 would match the
used class (TT, IN, CD), this will change slightly when the ptw
supports nested translation as it can also issue TT event with
class IN.
In case for stage-2 only translation, used in the context of nested
translation, the stage and asid are saved and restored before and
after calling smmu_translate().
Translating CD or TTBx can fail for the following reasons:
1) Large address size: This is described in
(3.4.3 Address sizes of SMMU-originated accesses)
- For CD ptr larger than IAS, for SMMUv3.1, it can trigger either
C_BAD_STE or Translation fault, we implement the latter as it
requires no extra code.
- For TTBx, if larger than the effective stage 1 output address size, it
triggers C_BAD_CD.
2) Faults from PTWs (7.3 Event records)
- F_ADDR_SIZE: large address size after first level causes stage 2 Address
Size fault (Also in 3.4.3 Address sizes of SMMU-originated accesses)
- F_PERMISSION: Same as an address translation. However, when
CLASS == CD, the access is implicitly Data and a read.
- F_ACCESS: Same as an address translation.
- F_TRANSLATION: Same as an address translation.
- F_WALK_EABT: Same as an address translation.
These are already implemented in the PTW logic, so no extra handling
required.
As in CD and TTBx translation context, the iova is not known, setting
the InputAddr was removed from "smmuv3_do_translate" and set after
from "smmuv3_translate" with the new function "smmuv3_fixup_event"

ASID and VMID used to be uint16_t in the translation config, however,
in other contexts they can be int as -1 in case of TLB invalidation,
to represent all (don’t care).
When stage-2 was added asid was set to -1 in stage-2 and vmid to -1
in stage-1 configs. However, that meant they were set as (65536),
this was not an issue as nesting was not supported and no
commands/lookup uses both.
With nesting, it’s critical to get this right as translation must be
tagged correctly with ASID/VMID, and with ASID=-1 meaning stage-2.
Represent ASID/VMID everywhere as int.

smmuv3_translate() does everything from STE/CD parsing to TLB lookup
and PTW.
Soon, when nesting is supported, stage-1 data (tt, CD) needs to be
translated using stage-2.
Split smmuv3_translate() to 3 functions:
- smmu_translate(): in smmu-common.c, which does the TLB lookup, PTW,
TLB insertion, all the functions are already there, this just puts
them together.
This also simplifies the code as it consolidates event generation
in case of TLB lookup permission failure or in TT selection.
- smmuv3_do_translate(): in smmuv3.c, Calls smmu_translate() and does
the event population in case of errors.
- smmuv3_translate(), now calls smmuv3_do_translate() for
translation while the rest is the same.
Also, add stage in trace_smmuv3_translate_success()

Currently, translation stage is represented as an int, where 1 is stage-1 and
2 is stage-2, when nested is added, 3 would be confusing to represent nesting,
so we use an enum instead.
While keeping the same values, this is useful for:
- Doing tricks with bit masks, where BIT(0) is stage-1 and BIT(1) is
stage-2 and both is nested.
- Tracing, as stage is printed as int.

The SMMUv3 spec (ARM IHI 0070 F.b - 7.3 Event records) defines the
class of events faults as:
CLASS: The class of the operation that caused the fault:
- 0b00: CD, CD fetch.
- 0b01: TTD, Stage 1 translation table fetch.
- 0b10: IN, Input address
However, this value was not set and left as 0 which means CD and not
IN (0b10).
Another problem was that stage-2 class is considered IN not TT for
EABT, according to the spec:
Translation of an IPA after successful stage 1 translation (or,
in stage 2-only configuration, an input IPA)
- S2 == 1 (stage 2), CLASS == IN (Input to stage)
This would change soon when nested translations are supported.
While at it, add an enum for class as it would be used for nesting.
However, at the moment stage-1 and stage-2 use the same class values,
except for EABT.

For the following events (ARM IHI 0070 F.b - 7.3 Event records):
- F_TRANSLATION
- F_ACCESS

- F_ADDR_SIZE
If fault occurs at stage 2, S2 == 1 and:
- If translating an IPA for a transaction (whether by input to
stage 2-only configuration, or after successful stage 1 translation),
CLASS == IN, and IPA is provided.
At the moment only CLASS == IN is used which indicates input
translation.
However, this was not implemented correctly, as for stage 2, the code
only sets the S2 bit but not the IPA.
This field has the same bits as FetchAddr in F_WALK_EABT which is
populated correctly, so we don’t change that.
The setting of this field should be done from the walker as the IPA address
wouldn't be known in case of nesting.
For stage 1, the spec says:
If fault occurs at stage 1, S2 == 0 and:
CLASS == IN, IPA is UNKNOWN.
So, no need to set it to for stage 1, as ptw_info is initialised by zero in
smmuv3_translate().

It is common practice when implementing double-buffering on VideoCore
to do so by multiplying the height of the virtual buffer by the
number of virtual screens desired (i.e., two - in the case of
double-bufferring).
At present, this won't work in QEMU because the logic in
fb_use_offsets require that both the virtual width and height exceed
their physical counterparts.
This appears to be unintentional/a typo and indeed the comment
states; "Experimentally, the hardware seems to do this only if the
viewport size is larger than the physical screen". The
viewport/virtual size would be larger than the physical size if
either virtual dimension were larger than their physical counterparts
and not necessarily both.

Commit b1f1e9dcfa renamed 'riscv,delegate' to 'riscv,delegation' since
it is the correct name as per dt-bindings, and the absence of the
correct name will result in validation fails when dumping the dtb and
using dt-validate.
But this change has a side-effect: every other firmware available that
is AIA capable is using 'riscv,delegate', and it will fault/misbehave if
this property isn't present. The property was added back in QEMU 7.0,
meaning we have 2 years of firmware development using the wrong
property.
Re-introducing 'riscv,delegate' while keeping 'riscv,delegation' allows
older firmwares to keep booting with the 'virt' machine.
'riscv,delegate' is then marked for future deprecation with its use
being discouraged from now on.

EXT_CSD values from Vincent's patch simplivied for Spec v4.3:
- Remove deprecated keys:
. EXT_CSD_SEC_ERASE_MULT
. EXT_CSD_SEC_TRIM_MULT
- Set some keys to not defined / implemented:
. EXT_CSD_HPI_FEATURES
. EXT_CSD_BKOPS_SUPPORT
. EXT_CSD_SEC_FEATURE_SUPPORT
. EXT_CSD_ERASE_TIMEOUT_MULT
. EXT_CSD_PART_SWITCH_TIME
. EXT_CSD_OUT_OF_INTERRUPT_TIME
- Simplify:
. EXT_CSD_ACC_SIZE (6 -> 1)
16KB of super_page_size -> 512B (BDRV_SECTOR_SIZE)
. EXT_CSD_HC_ERASE_GRP_SIZE (4 -> 1)

. EXT_CSD_S_A_TIMEOUT (17 -> 1)
. EXT_CSD_CARD_TYPE (7 -> 3)
Dual data rate -> High-Speed mode
- Update:
. EXT_CSD_CARD_TYPE (7 -> 3)
High-Speed MultiMediaCard @ 26MHz & 52MHz
. Performances (0xa -> 0x46)
Class B at 3MB/s. -> Class J at 21MB/s
. EXT_CSD_REV (5 -> 3)
Rev 1.5 (spec v4.41) -> Rev 1.3 (spec v4.3)
- Use load/store API to set EXT_CSD_SEC_CNT
- Remove R/W keys, normally zeroed at reset
. EXT_CSD_BOOT_INFO
Migrate the Modes segment (192 lower bytes) but not the
full EXT_CSD register, see Spec v4.3, chapter 8.4
"Extended CSD register":
The Extended CSD register defines the card properties
and selected modes. It is 512 bytes long. The most
significant 320 bytes are the Properties segment, which
defines the card capabilities and cannot be modified by
the host. The lower 192 bytes are the Modes segment,
which defines the configuration the card is working in.
These modes can be changed by the host by means of the
SWITCH command.

Since eMMC are soldered on boards, it is not user-creatable.
RCA register is initialized to 0x0001, per spec v4.3,
chapter 8.5 "RCA register":
The default value of the RCA register is 0x0001.
The value 0x0000 is reserved to set all cards into
the Stand-by State with CMD7.
The CSD register is very similar to SD one, except
the version announced is v4.3.
eMMC CID register is slightly different from SD:
- One extra PNM (5 -> 6)
- MDT is only 1 byte (2 -> 1).

Remove dpy_cursor_define_supported() as it brings no benefit today and
it has a few inherent problems.
All graphical displays except egl-headless support cursor composition
without DMA-BUF, and egl-headless is meant to be used in conjunction
with another graphical display, so dpy_cursor_define_supported()
always returns true and meaningless.
Even if we add a new display without cursor composition in the future,
dpy_cursor_define_supported() will be problematic as a cursor display
fix for it because some display devices like virtio-gpu cannot tell the
lack of cursor composition capability to the guest and are unable to
utilize the value the function returns. Therefore, all non-headless
graphical displays must actually implement cursor composition for
correct cursor display.
Another problem with dpy_cursor_define_supported() is that it returns
true even if only some of the display listeners support cursor
composition, which is wrong unless all display listeners that lack
cursor composition is headless.

Commit 3089637461 ("scsi: Don't ignore most usb-storage properties")
removed the call to object_property_set_int() and thus the 'set'
method for the bootindex property was also not called anymore. Here
that method is device_set_bootindex() (as configured by
scsi_dev_instance_init() -> device_add_bootindex_property()) which as
a side effect registers the device via add_boot_device_path().
As reported by a downstream user [0], the bootindex property did not
have the desired effect anymore for legacy drives. Fix the regression
by explicitly calling the add_boot_device_path() function after
checking that the bootindex is not yet used (to avoid
add_boot_device_path() calling exit()).

This causes the "Check Point R81.20 Gaia" appliance [0] to fail to

With a limit of 150, the appliance still fails to boot, while with a

Currently if the 'legacy-vm-type' property of the sev-guest object is
'on', QEMU will attempt to use the newer KVM_SEV_INIT2 kernel
interface in conjunction with the newer KVM_X86_SEV_VM and
KVM_X86_SEV_ES_VM KVM VM types.
This can lead to measurement changes if, for instance, an SEV guest was
created on a host that originally had an older kernel that didn't
support KVM_SEV_INIT2, but is booted on the same host later on after the
host kernel was upgraded.
Instead, if legacy-vm-type is 'off', QEMU should fail if the
KVM_SEV_INIT2 interface is not provided by the current host kernel.
Modify the fallback handling accordingly.
In the future, VMSA features and other flags might be added to QEMU
which will require legacy-vm-type to be 'off' because they will rely
on the newer KVM_SEV_INIT2 interface. It may be difficult to convey to
users what values of legacy-vm-type are compatible with which
features/options, so as part of this rework, switch legacy-vm-type to a
tri-state OnOffAuto option. 'auto' in this case will automatically
switch to using the newer KVM_SEV_INIT2, but only if it is required to
make use of new VMSA features or other options only available via
KVM_SEV_INIT2.
Defining 'auto' in this way would avoid inadvertantly breaking
compatibility with older kernels since it would only be used in cases
where users opt into newer features that are only available via
KVM_SEV_INIT2 and newer kernels, and provide better default behavior
than the legacy-vm-type=off behavior that was previously in place, so
make it the default for 9.1+ machine types.

PF initializes SR-IOV VF BAR0 region in nvme_init_sriov() with bar_size
calcaulted by Primary Controller Capability such as VQFRSM and VIFRSM
rather than `max_ioqpairs` and `msix_qsize` which is for PF only.
In this case, the bar size reported in nvme_init_sriov() by PF and
nvme_init_pci() by VF might differ especially with large number of
sriov_max_vfs (e.g., 127 which is curret maximum number of VFs). And
this reports invalid BAR0 address of VFs to the host operating system
so that MMIO access will not be caught properly and, of course, NVMe
driver initialization is failed.
For example, if we give the following options, BAR size will be
initialized by PF with 4K, but VF will try to allocate 8K BAR0 size in
nvme_init_pci().
#!/bin/bash
nr_vf=$((127))
nr_vq=$(($nr_vf * 2 + 2))
nr_vi=$(($nr_vq / 2 + 1))
nr_ioq=$(($nr_vq + 2))

To fix this issue, this patch modifies the calculation of BAR size in

The MQES field in the CAP register describes the Maximum Queue Entries
Supported for the IO queues of an NVMe controller. Adding a +1 to the
value in this field results in the total queue size. A full queue is
when a queue of size N contains N - 1 entries, and the minimum queue
size is 2. Thus the lowest MQES value is 1.
This patch adds the new mqes property to the NVMe emulation which allows
a user to specify the maximum queue size by setting this property. This
is useful as it enables testing of NVMe controller where the MQES is
relatively small. The smallest NVMe queue size supported in NVMe is 2
submission and completion entries, which means that the smallest legal
mqes value is 1.
The following example shows how the mqes can be set for a the NVMe
emulation:
-drive id=nvme0,if=none,file=nvme.img,format=raw
-device nvme,drive=nvme0,serial=foo,mqes=1
If the mqes property is not provided then the default mqes will still be
0x7ff (the queue size is 2048 entries).

Now the USART connects to the EXTI inbound GPIOs, and the EXTI connects
its IRQs to the CPU.
The existing QTest for the USART (tests/qtest/stm32l4x5_usart-test.c)

The current implementation of bcm2835_thermal_ops sets
impl.max_access_size and valid.min_access_size to 4, but leaves
impl.min_access_size and valid.max_access_size unset, defaulting to 1.
This causes issues when the memory system is presented with an access
of size 2 at an offset of 3, leading to an attempt to synthesize it as
a pair of byte accesses at offsets 3 and 4, which trips an assert.
Additionally, the lack of valid.max_access_size setting causes another
issue: the memory system tries to synthesize a read using a 4-byte
access at offset 3 even though the device doesn't allow unaligned
accesses.
This patch addresses these issues by explicitly setting both
impl.min_access_size and valid.max_access_size to 4, ensuring proper
handling of access sizes.

In pl011_get_baudrate(), when we calculate the baudrate we can
accidentally divide by zero. This happens because although (as the
specification requires) we treat UARTIBRD = 0 as invalid, we aren't
correctly limiting UARTIBRD and UARTFBRD values to the 16-bit and 6-bit
ranges the hardware allows, and so some non-zero values of UARTIBRD can
result in a zero divisor.
Enforce the correct register field widths on guest writes and on inbound
migration to avoid the division by zero.

The error message is actually expressive, considering QEMU only. But
when called from Libvirt, talking about "size" can be confusing, because
in Libvirt "size" translates to the memory backend size in QEMU (maximum
size) and "current" translates to the QEMU "size" property.
Let's simply avoid talking about the "size" property and spell out that
some device memory is still plugged.

Really the problem here is the return values of fit_load_[kernel|fdt]() are a
little all over the place. However we don't want to somehow get
through not having set kernel_end and having it just be random unused

romsize is an uint32_t variable. Specifying -1 as an uint32_t value is
obscure way to denote UINT32_MAX.
Worse, if int is wider than 32-bit, it will change the behavior of a
construct like the following:
romsize = -1;
if (romsize != -1) {
...
}
When -1 is assigned to romsize, -1 will be implicitly casted into
uint32_t, resulting in UINT32_MAX. On contrary, when evaluating
romsize != -1, romsize will be casted into int, and it will be a
comparison of UINT32_MAX and -1, and result in false.
Replace -1 with UINT32_MAX for statements involving the variable to
clarify the intent and prevent potential breakage.

When a VFIO device is hoplugged in a VM using virtio-iommu, IOMMUPciBus
and IOMMUDevice cache entries are created in the .get_address_space()
handler of the machine IOMMU device. However, these entries are never
destroyed, not even when the VFIO device is detached from the machine.
This can lead to an assert if the device is reattached again.
When reattached, the .get_address_space() handler reuses an
IOMMUDevice entry allocated when the VFIO device was first attached.
virtio_iommu_set_host_iova_ranges() is called later on from the
.set_iommu_device() handler an fails with an assert on 'probe_done'
because the device appears to have been already probed when this is
not the case.
The IOMMUDevice entry is allocated in pci_device_iommu_address_space()
called from under vfio_realize(), the VFIO PCI realize handler. Since
pci_device_unset_iommu_device() is called from vfio_exitfn(), a sub
function of the PCIDevice unrealize() handler, it seems that the
.unset_iommu_device() handler is the best place to release resources
allocated at realize time. Clear the IOMMUDevice cache entry there to
fix hotplug.

Commit d152cdd6f6 ("virtio: use virtio accessor to access packed event")
switched using of address_space_read_cached() to virito_lduw_phys_cached()
to access packed descriptor event.
When we used address_space_read_cached(), we needed to call
virtio_tswap16s() to handle the endianess of the field, but
virito_lduw_phys_cached() already handles it internally, so we no longer
need to call virtio_tswap16s() (as the commit had done for `off_wrap`,
but forgot for `flags`).

It's observed that Linux kernel booting with the VM reports a "conflicting
mapping for input ID" FW_BUG.
The IORT doc defines "Number of IDs" to be "the number of IDs in the range
minus one", while virt-acpi-build.c simply stores the number of IDs in the
id_count without the "minus one". Meanwhile, some of the callers pass in a
0xFFFF following the spec. So, this is a mismatch between the function and
its callers.
Fix build_iort_id_mapping() by internally subtracting one from the pass-in
@id_count. Accordingly make sure that all existing callers pass in a value
without the "minus one", i.e. change all 0xFFFFs to 0x10000s.
Also, add a few lines of comments to highlight this change along with the
referencing document for this build_iort_id_mapping().

In e820_add_entry() the e820_table is reallocated with g_renew() to make
space for a new entry. However, fw_cfg_arch_create() just uses the
existing e820_table pointer. This leads to a use-after-free if anything
adds a new entry after fw_cfg is set up.
Shift the addition of the etc/e820 file to the machine done notifier, via
a new fw_cfg_add_e820() function.
Also make e820_table private and use an e820_get_table() accessor function
for it, which sets a flag that will trigger an assert() for any *later*
attempts to add to the table.
Make e820_add_entry() return void, as most callers don't check for error
anyway.

The CSD::CSR_IMP bit defines whether the Driver Stage
Register (DSR) is implemented or not. We do not set
this bit in CSD:
static void sd_set_csd(SDState *sd, uint64_t size)
{
...
if (size <= SDSC_MAX_CAPACITY) { /* Standard Capacity SD */
...
sd->csd[6] = 0xe0 | /* Partial block for read allowed */
((csize >> 10) & 0x03);
...
} else { /* SDHC */
...
sd->csd[6] = 0x00;
...
}
...
}
The sd_normal_command() switch case for the SEND_DSR
command do nothing and fallback to "illegal command".
Since the command is mandatory (although the register
isn't...) call the sd_cmd_unimplemented() handler.

All commands switching from TRANSFER state to (receiving)DATA
do the same: receive stream of data from the DAT lines. Instead
of duplicating the same code many times, introduce 2 helpers:
- sd_cmd_to_receivingdata() on the I/O line setup the data to
be received on the data[] buffer,
- sd_generic_write_byte() on the DAT lines to push the data.
