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.

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:

hw/arm/smmu-common: Check SMMU has PCIe Root Complex association
We only allow default PCIe Root Complex(pcie.0) or pxb-pcie based extra
root complexes to be associated with SMMU.
Although this change does not affect functionality at present, it is
required when we add support for user-creatable SMMUv3 devices in
future patches.
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
is added and validated with SMMUv3.

hw/arm/virt-acpi-build: Re-arrange SMMUv3 IORT build
Introduce a new struct AcpiIortSMMUv3Dev to hold all the information
required for SMMUv3 IORT node and use that for populating the node.
The current machine wide SMMUv3 is named as legacy SMMUv3 as we will
soon add support for user-creatable SMMUv3 devices. These changes will
be useful to have common code paths when we add that support.

hw/arm/virt-acpi-build: Update IORT for multiple smmuv3 devices
With the soon to be introduced user-creatable SMMUv3 devices for
virt, it is possible to have multiple SMMUv3 devices associated

Update IORT nodes accordingly.
An example IORT Id mappings for a Qemu virt machine with two
PCIe Root Complexes each assocaited with a SMMUv3 will
be something like below,
-device arm-smmuv3,primary-bus=pcie.0,id=smmuv3.0
-device arm-smmuv3,primary-bus=pcie.1,id=smmuv3.1

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.

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.

hw/usb/network: Remove hardcoded 0x40 prefix in STRING_ETHADDR response
USB NICs have a "40:" prefix hardcoded for all MAC addresses when we
return the guest the MAC address if it queries the STRING_ETHADDR USB
string property. This doesn't match what we use for the
OID_802_3_PERMANENT_ADDRESS or OID_802_3_CURRENT_ADDRESS OIDs for
NDIS, or the MAC address we actually use in the QEMU networking code
to send/receive packets for this device, or the NIC info string we
print for users. In all those other places we directly use
s->conf.macaddr.a, which is the full thing the user asks for.
This overrides user-provided configuration and leads to an inconsistent
experience.
I couldn't find any documented reason (comment or git commits) for
this behavior. It seems like everyone is just expecting the MAC
address to be fully passed through to the guest, but it isn't.
This may have been a debugging hack that accidentally made it through
to the accepted patch: it has been in the code since it was originally
added back in 2008.
This is also particularly problematic as the "40:" prefix isn't a
reserved prefix for MAC addresses (IEEE OUI). There are a number of
valid allocations out there which use this prefix, meaning that QEMU
may be causing MAC address conflicts.

tracetool: add test suite for tracetool with reference output
When reviewing tracetool patches it is often very unclear what the
expected output will be for the generated backends. Compounding
this is that a default build will only enable the 'log' trace
backend, so developers won't see generated code for other backends
without making a special effort. Some backends are also platform
specific, so can't be enabled in QEMU builds, even though tracetool
could generate the code.
To address this, introduce a test suite for tracetool which is
conceptually similar to the qapi-schema test. It is a simple
python program that runs tracetool and compares the actual output
to historical reference output kept in git. The test directly
emits TAP format logs for ease of integration with meson.
This can be run with
make check-tracetool
to make it easier for developers changing generated output, the
sample expected content can be auto-recreated
QEMU_TEST_REGENERATE=1 make check-tracetool
and the changes reviewed and added to the commit. This will also
assist reviewers interpreting the change.
Developers are reminded of this in the test output on failure:
$ make check-tracetool
1/6 qemu:tracetool / dtrace OK 0.14s
2/6 qemu:tracetool / ftrace FAIL 0.06s exit status 1

tracetool: drop the probe "__nocheck__" wrapping
Every generated inline probe function is wrapped with a
trivial caller that has a hard-coded condition test:
static inline void _nocheck__trace_test_wibble(void * context, int value)
{
tracepoint(qemu, test_wibble, context, value);
}
static inline void trace_test_wibble(void * context, int value)
{
if (true) {
_nocheck__trace_test_wibble(context, value);
}
}
This was introduced for TCG probes back in
864a2178: trace: [tcg] Do not generate TCG code to trace dynamically-disabled
events
but is obsolete since
126d4123 tracing: excise the tcg related from tracetool
This commit removes the wrapping such that we have
static inline void trace_test_wibble(void * context, int value)
{
tracepoint(qemu, test_wibble, context, value);
}
The default build of qemu-system-x86_64 on Fedora with the
'log' backend, has its size reduced by 1 MB
