83d9019202 vfio/display: Fix vfio_display_edid_init() error path
vfio_display_edid_init() can fail for many reasons and return silently.
It would be good to report the error.

Old mdev driver may not support vfio edid region and we allow to go
through in this case.

vfio_display_edid_update() isn't changed because it can be called at
runtime when UI changes (i.e. window resize).

956b30b9cf virtio-iommu: Revert transient enablement of IOMMU MR in bypass mode
In 94df5b2180 ("virtio-iommu: Fix 64kB host page size VFIO device
assignment"), in case of bypass mode, we transiently enabled the
IOMMU MR to allow the set_page_size_mask() to be called and pass
information about the page size mask constraint of cold plugged
VFIO devices. Now we do not use the IOMMU MR callback anymore, we
can just get rid of this hack.

2457343d05 memory: remove IOMMU MR iommu_set_page_size_mask() callback
Everything is now in place to use the Host IOMMU Device callbacks
to retrieve the page size mask usable with a given assigned device.
This new method brings the advantage to pass the info much earlier
to the virtual IOMMU and before the IOMMU MR gets enabled. So let's
remove the call to memory_region_iommu_set_page_size_mask in
vfio common.c and remove the single implementation of the IOMMU MR
callback in the virtio-iommu.c

d7c8c95fbc virtio-iommu : Retrieve page size mask on virtio_iommu_set_iommu_device()
Retrieve the Host IOMMU Device page size mask when this latter is set.
This allows to get the information much sooner than when relying on
IOMMU MR set_page_size_mask() call, whcih happens when the IOMMU MR
gets enabled. We introduce check_page_size_mask() helper whose code
is inherited from current virtio_iommu_set_page_size_mask()
implementation. This callback will be removed in a subsequent patch.

Besides, users are able to utilize "Write Status Register 1(0x01)"

utilize "Read Status Register 2(0x35)" command to get the QE bit status.

To support quad mode for w25q01jvq, update collecting data needed

in complete_collecting_data.

f5fcc64808 hw/core: ensure kernel_end never gets used undefined
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

The compiler complained on an --enable-gcov build:

6a67577d80 hw/pci: Replace -1 with UINT32_MAX for romsize
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.

1b889d6e39 virtio-iommu: Clear IOMMUDevice when VFIO device is unplugged
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.

7aa6492401 virtio: remove virtio_tswap16s() call in vring_packed_event_read()
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`).

efc4ad6f99 hw/cxl/events: Improve QMP interfaces and documentation for add/release dynamic capacity.
New DCD command definitions updated in response to review comments
from Markus.

- Used CxlXXXX instead of CXLXXXXX for newly added types.
- Expanded some abreviations in type names to be easier to read.
- Additional documentation for some fields.
- Replace slightly vague cxl r3.1 references with
  "Compute Express Link (CXL) Specification, Revision 3.1, XXXX"
  to bring them inline with what it says on the specification cover.

5786827f47 hw/arm/virt-acpi-build: Fix id_count in build_iort_id_mapping
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().

Fixes: 42e0f050e3 ("hw/arm/virt-acpi-build: Add IORT support to bypass SMMUv3")
