The qtests are broken since a while in the MSYS2 job in the gitlab-CI,
likely due to some changes in the MSYS2 environment. So far nobody has
neither a clue what's going wrong here, nor an idea how to fix this
(in fact most QEMU developers even don't have a Windows environment
available for properly analyzing this problem), so we should disable the
qtests here for the time being to get at least test coverage again
for the remaining tests that are run here.
Since we already get compile-test coverage for the system emulation
in the cross-win64-system job, and since the MSYS2 job is one of the
longest running jobs in our CI (it takes more than 1 hour to complete),
let's seize the opportunity and also cut the run time by disabling
the system emulation completely here, including the libraries that
are only useful for system emulation. In case somebody ever figures
out the failure of the qtests on MSYS2, we can revert this patch
to get everything back.

In commit 412d294ffd we tried to improve the error message printed when
the machine type is unknown, but we used the wrong variable, resulting in:
$ ./build/x86/qemu-system-aarch64 -M bang
qemu-system-aarch64: unsupported machine type: "(null)"
Use -machine help to list supported machines
Use the right variable, so we produce more helpful output:
$ ./build/x86/qemu-system-aarch64 -M bang
qemu-system-aarch64: unsupported machine type: "bang"
Use -machine help to list supported machines
Note that we must move the qdict_del() to below the error_setg(),
because machine_type points into the value of that qdict entry,
and deleting it will make the pointer invalid.

The two limit_max variables represent size - 1, just like the

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
The crash was reported in MAC OS and NixOS, here is the link for this bug
https://gitlab.com/qemu-project/qemu/-/issues/2334https://gitlab.com/qemu-project/qemu/-/issues/2321
In this bug, they are using the virtio_input device. The guest notifier was
not supported for this device, The function virtio_pci_set_guest_notifiers()
was not called, and the vector_irqfd was not initialized.
So the fix is adding the check for vector_irqfd in virtio_pci_get_notifier()
The function virtio_pci_get_notifier() can be used in various devices.
It could also be called when VIRTIO_CONFIG_S_DRIVER_OK is not set. In this situation,
the vector_irqfd being NULL is acceptable. We can allow the device continue to boot
If the vector_irqfd still hasn't been initialized after VIRTIO_CONFIG_S_DRIVER_OK
is set, it means that the function set_guest_notifiers was not called before the
driver started. This indicates that the device is not using the notifier.
At this point, we will let the check fail.
This fix is verified in vyatta,MacOS,NixOS,fedora system.

Since commit 4ccd5fe22f ('pc: add option
to disable PS/2 mouse/keyboard'), the vmport will not be created unless
the i8042 PS/2 controller is enabled. To avoid confusion, let's fail if
vmport was explicitly requested, but the i8042 controller is disabled.
This also changes the behavior of vmport=auto to take i8042 controller
availability into account.

_console_interaction reads data from the console even when there is only
an input string to send, and no output data to wait on. This can cause
lines to be missed by wait_for_console_pattern calls that follows an
exec_command. Fix this by not reading the console if there is no pattern
to wait for.
This solves occasional hangs in ppc_hv_tests.py, usually when run on KVM
hosts that are fast enough to output important lines quickly enough to be
consumed by exec_command, so they get missed by subsequent wait for
pattern calls.

Directly invoking the DeviceClass::reset method is a bad idea,
because if the device is using three-phase reset then it relies on
transitional reset machinery which is likely to disappear at some

In axidma_class_init() we accidentally used a comma at the end of
a statement rather than a semicolon. This has no ill effects, but
it's obviously not intended and it means that Coccinelle scripts

When refactoring page_table_walk_refill() in commit 4e999bf419
we missed the indirect call to cpu_mmu_index() in get_pte():
page_table_walk_refill()
-> get_pte()
-> cpu_ld[lq]_code()
-> cpu_mmu_index()
Since we don't mask anymore the modes in hflags, cpu_mmu_index()
can return UM or SM, while we only expect KM or ERL.
Fix by propagating ptw_mmu_idx to get_pte(), and use the
cpu_ld/st_code_mmu() API with the correct MemOpIdx.

Revert "hw/riscv/virt.c: imsics DT: add '#msi-cells'"
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
This reverts commit f42cdf2ea5.
Linux does not properly handle '#msi-cells=<0>' when searching for
MSI controllers for PCI devices which results in the devices being
unable to use MSIs. A patch for Linux has been sent[1] but until it,
or something like it, is merged and in distro kernels we should stop
adding the property. It's harmless to stop adding it since the
absence of the property and a value of zero for the property mean
the same thing according to the DT binding definition.

A deadlock can be created if a new vcpu (a) triggers a scoreboard
reallocation, and another vcpu (b) wants to create a new scoreboard at
the same time.
In this case, (a) holds the plugin lock, and starts an exclusive
section, waiting for (b). But at the same time, (b) is waiting for
plugin lock.
The solution is to drop the lock before entering the exclusive section.
This bug can be easily reproduced by creating a callback for any tb
exec, that allocates a new scoreboard. In this case, as soon as we reach
more than 16 vcpus, the deadlock occurs.
