d35146a660 qtest/bios-tables-test: Update tables for smmuv3 tests
For the legacy smmuv3 test case, generated IORT has a single SMMUv3 node,
a Root Complex(RC) node and 1 ITS node.
RC node features 4 ID mappings, of which 2 points to SMMU node and the
remaining ones points to ITS.

       pcie.0 -> {SMMU0} -> {ITS}
{RC}   pcie.1 -> {SMMU0} -> {ITS}
       pcie.2            -> {ITS}
       [all other ids]   -> {ITS}

For the smmuv3-dev test case, IORT has 2 SMMUV3 nodes,
1 RC node and 1 ITS node.
RC node features 4 ID mappings. 2 of them target the 2
SMMU nodes while the others targets the ITS.

3f8cd046c1 qtest/bios-tables-test: Add tests for legacy smmuv3 and smmuv3 device
For the legacy SMMUv3 test, the setup includes three PCIe Root Complexes,
one of which has bypass_iommu enabled. The generated IORT table contains
a single SMMUv3 node, a Root Complex(RC) node and 1 ITS node.
RC node features 4 ID mappings, of which 2 points to SMMU node and the
remaining ones points to ITS.

       pcie.0 -> {SMMU0} -> {ITS}
{RC}   pcie.1 -> {SMMU0} -> {ITS}
       pcie.2            -> {ITS}
       [all other ids]   -> {ITS}

For the -device arm-smmuv3,... test, the configuration also includes three
Root Complexes, with two connected to separate SMMUv3 devices.
The resulting IORT table contains 1 RC node, 2 SMMU nodes and 1 ITS node.
RC node features 4 ID mappings. 2 of them target the 2 SMMU nodes while
the others targets the ITS.

        pcie.0 -> {SMMU0} -> {ITS}
{RC}    pcie.1 -> {SMMU1} -> {ITS}
        pcie.2            -> {ITS}

66d2f665e1 hw/arm/virt: Allow user-creatable SMMUv3 dev instantiation
Allow cold-plugging of an SMMUv3 device on the virt machine when no
global (legacy) SMMUv3 is present or when a virtio-iommu is specified.

This user-created SMMUv3 device is tied to a specific PCI bus provided
by the user, so ensure the IOMMU ops are configured accordingly.

Due to current limitations in QEMU’s device tree support, specifically
its inability to properly present pxb-pcie based root complexes and
their devices, the device tree support for the new SMMUv3 device is
limited to cases where it is attached to the default pcie.0 root complex.

951bc76fb6 hw/pci: Introduce pci_setup_iommu_per_bus() for per-bus IOMMU ops retrieval
Currently, pci_setup_iommu() registers IOMMU ops for a given PCIBus.
However, when retrieving IOMMU ops for a device using
pci_device_get_iommu_bus_devfn(), the function checks the parent_dev
and fetches IOMMU ops from the parent device, even if the current
bus does not have any associated IOMMU ops.

This behavior works for now because QEMU's IOMMU implementations are
globally scoped, and host bridges rely on the bypass_iommu property
to skip IOMMU translation when needed.

However, this model will break with the soon to be introduced
arm-smmuv3 device, which allows users to associate the IOMMU
with a specific PCIe root complex (e.g., the default pcie.0
or a pxb-pcie root complex).

For example, consider the following setup with multiple root
complexes:

-device arm-smmuv3,primary-bus=pcie.0,id=smmuv3.0 \
...
-device pxb-pcie,id=pcie.1,bus_nr=8,bus=pcie.0 \
-device pcie-root-port,id=pcie.port1,bus=pcie.1 \
-device virtio-net-pci,bus=pcie.port1

In Qemu, pxb-pcie acts as a special root complex whose parent is
effectively the default root complex(pcie.0). Hence, though pcie.1
has no associated SMMUv3 as per above, pci_device_get_iommu_bus_devfn()
will incorrectly return the IOMMU ops from pcie.0 due to the fallback
via parent_dev.

To fix this, introduce a new helper pci_setup_iommu_per_bus() that
explicitly sets the new iommu_per_bus field in the PCIBus structure.
This helper will be used in a subsequent patch that adds support for
the new arm-smmuv3 device.

Update pci_device_get_iommu_bus_devfn() to use iommu_per_bus when
determining the correct IOMMU ops, ensuring accurate behavior for
per-bus IOMMUs.

Note: Added a specific check to identify pxb-pcie to avoid matching
pxb-cxl host bridges, which are also of type PCI_HOST_BRIDGE. This
restriction can be relaxed once support for CXL devices on arm/virt

030f0ba117 target/arm: Added support for SME register exposure to GDB
The QEMU GDB stub does not expose the ZA storage SME register to GDB
via the remote serial protocol, which can be a useful functionality
to debug SME code.  To provide this functionality for AArch64
targets, this patch registers the SME register set with the GDB stub.
To do so, this patch implements the aarch64_gdb_get_sme_reg() and
aarch64_gdb_set_sme_reg() functions to specify how to get and set the
SME registers, and the arm_gen_dynamic_smereg_feature() function to
generate the target description in XML format to indicate the target
architecture supports SME.  Finally, this patch includes a
dyn_smereg_feature structure to hold this GDB XML description of the
SME registers for each CPU.

Note that according to the GDB documentation the ZA register is
defined as a vector of bytes; however the target description xml
retrieved when using gdb natively on a host with SME capabilities
represents the ZA register as a vector of vectors of bytes, so this
is a GDB documentation error.  We follow GDB's own gdbstub
implementation and represent the ZA register as a vector of vectors
of bytes as is done by GDB here:

At least try to give the user a hint which registers had a problem,
even if they cannot really do anything about it right now.

Sample output:

Could not set register op0:3 op1:0 crn:0 crm:0 op2:0 to c00fac31 (is 413fd0c1)

We could be even more helpful once we support writable ID registers,
at which point the user might actually be able to configure something
that is migratable.

cdafe5bd90 target/arm: Remove XScale and iWMMXt translate.c code
Remove all the translator code that is accessible only via
ARM_FEATURE_XSCALE or ARM_FEATURE_IWMMXT.  This includes the
xscale-only cp15_cpar TB flags and cpu_{V0,V1,M0} TCG temps.

The no-longer-used helper functions will be removed in a separate
commit.

5b3764d9e3 target/arm: Remove deprecated pxa CPU family
In 10.0 we deprecated the pxa CPU family (pxa250, pxa255, pxa260
pxa261, pxa262, pxa270-a0, pxa270-a1, pxa270, pxa270-b0, pxa270-b1,
pxa270-c0, pxa270-c5).  Now we have released 10.1 we can remove them.

This commit removes only the top level CPU definitions and updates
the documentation. Removing the CPUs means that there is now a lot
of dead iwMMXt code, which we will delete in subsequent commits.

cc2c5027dc hw/arm/raspi4b: remove redundant check in raspi_add_memory_node
The if (acells == 0 || scells == 0) check is redundant in
raspi_add_memory_node, since it is already checked in the call
chain, arm_load_dtb. Also the return value of the function is
not checked/used so it's removed.

424dc390ec tests, scripts: Don't import print_function from __future__
Some of our Python scripts still include the line
  from __future__ import print_function

which is intended to allow a Python 2 to handle the Python 3 print()
syntax. This particular part of the future arrived many years ago,
and our minimum Python version is 3.9, so we don't need to keep
this line around.

NB: the scripts in tests/tcg/*/gdbstub/ are run with whatever Python
gdb was built against, but we can safely assume that that was a
Python 3 because our supported distros are all on Python 3.  In any
case these are only run as part of "make check-tcg", not by
end-users.

Commit created with:

 sed -i -e '/import print_function/d' $(git grep -l 'from __future__')

606978500c block/curl: fix curl internal handles handling
block/curl.c uses CURLMOPT_SOCKETFUNCTION to register a socket callback.
According to the documentation, this callback is called not just with
application-created sockets but also with internal curl sockets, - and
for such sockets, user data pointer is not set by the application, so
the result qemu crashing.

Pass BDRVCURLState directly to the callback function as user pointer,
instead of relying on CURLINFO_PRIVATE.

This problem started happening with update of libcurl from 8.9 to 8.10 --
apparently with this change curl started using private handles more.

(CURLINFO_PRIVATE is used in one more place, in curl_multi_check_completion() -
it might need a similar fix too)

e502e614f4 hw/i386/pc_piix.c: remove unnecessary if() from pc_init1()
Now that the isapc logic has been split out of pc_piix.c, the PCI Host Bridge
(phb) object is now always set in pc_init1().

Since phb is now guaranteed not to be NULL, Coverity reports that the if()
statement surrounding ioapic_init_gsi() is now unnecessary and can be removed
along with the phb NULL initialiser.

Coverity: CID 1620557
