hw/gpio/aspeed: Add reg_table_count to AspeedGPIOClass

ASan detected a global-buffer-overflow error in the aspeed_gpio_read()
function. This issue occurred when reading beyond the bounds of the
reg_table.

To enhance the safety and maintainability of the Aspeed GPIO code, this commit
introduces a reg_table_count member to the AspeedGPIOClass structure. This
change ensures that the size of the GPIO register table is explicitly tracked
and initialized, reducing the risk of errors if new register tables are
introduced in the future.

hw: skip registration of outdated versioned machine types

This calls the MACHINE_VER_DELETION() macro in the machine type
registration method, so that when a versioned machine type reaches
the end of its life, it is no longer registered with QOM and thus
cannot be used.

The actual definition of the machine type should be deleted at

By skipping registration the manual code deletion task can be

include/hw: temporarily disable deletion of versioned machine types

The new deprecation and deletion policy for versioned machine types is
being introduced in QEMU 9.1.0.

Under the new policy a number of old machine types (any prior to 2.12)
would be liable for immediate deletion which would be a violation of our
historical deprecation and removal policy

Thus automatic deletions (by skipping QOM registration) are temporarily
gated on existance of the env variable "QEMU_DELETE_MACHINES" / QEMU
version number >= 10.1.0. This allows opt-in testing of the automatic
deletion logic, while activating it fully in QEMU >= 10.1.0.

This whole commit should be reverted in the 10.1.0 dev cycle or shortly
thereafter.

To get a standardized deprecation message and avoid having to remember
to manually add it after three years, this introduces two macros to be
used by targets when defining versioned machines.

* MACHINE_VER_DEPRECATION(major, minor)

  Automates the task of setting the 'deprecation_reason' field on the
  machine, if-and-only-if the major/minor version is older than 3 years.

* MACHINE_VER_DELETION(major, minor)

  Simulates the deletion of by skipping registration of the QOM type
  for a versioned machine, if-and-only-if the major/minor version is
  older than 6 years.

By using these two macros there is no longer any manual work required
per-release to deprecate old machines. By preventing the use of machines
that have reached their deletion date, it is also not necessary to
manually delete machines per-release. Deletion can be batched up once a
year or whenever makes most sense.

tests/qtest: Ensure STM32L4x5 EXTI state is correct at the end of QTests

EXTI's new field `irq_levels` tracks irq levels between tests when using
`global_qtest`.
This happens in `stm32l4x5_exti-test.c`, `stm32l4x5_syscfg-test.c` and
`stm32l4x5_gpio-test.c` (`dm163.c` doesn't use `global_qtest`).

To ensure that `irq_levels` has the same value before and after each
QTest, this commit toggles back the irq lines that were changed at the
end of each problematic test. Most QTests were already doing this.

tests/qtest: Fix STM32L4x5 SYSCFG irq line 15 state assumption

The QTest `test_irq_pin_multiplexer` makes the assumption that the
reset state of irq line 15 is low, which is false since STM32L4x5 GPIO
was implemented (the reset state of pin GPIOA15 is high because there's
pull-up and it results in the irq line 15 also being high at reset).

It wasn't triggering an error because `test_interrupt` was mistakenly
"resetting" the line low.

This commit corrects these two mistakes by :
- not setting the line low in `test_interrupt`
- using an irq line in `test_irq_pin_multiplexer` which is low at reset

xen-hvm: Avoid livelock while handling buffered ioreqs

A malicious or buggy guest may generated buffered ioreqs faster than
QEMU can process them in handle_buffered_iopage(). The result is a
livelock - QEMU continuously processes ioreqs on the main thread without
iterating through the main loop which prevents handling other events,
processing timers, etc. Without QEMU handling other events, it often
results in the guest becoming unsable and makes it difficult to stop the
source of buffered ioreqs.

To avoid this, if we process a full page of buffered ioreqs, stop and
reschedule an immediate timer to continue processing them. This lets
QEMU go back to the main loop and catch up.

tests/avocado: use default amount of cores on sbsa-ref

The version of the sbsa-ref EDK2 firmware we used to use in this test
had a bug where it might make an unaligned access to the framebuffer,
which causes a guest crash on newer versions of QEMU where we enforce
the architectural requirement that unaligned accesses to Device memory
should take an exception.

We happened to not notice this because our test was booting with "-smp
1" and through luck this didn't write the boot logo to the framebuffer
at an unaligned address; but trying to boot the same firmware with two
CPUs would result in a guest crash. Now we have updated the firmware
we're using for the test, we can make the test use all the cores on the
board, so we are testing the SMP boot path.

tests/avocado: update firmware for sbsa-ref

Update firmware to have graphics card memory fix from EDK2 commit
c1d1910be6e04a8b1a73090cf2881fb698947a6e:

    OvmfPkg/QemuVideoDxe: add feature PCD to remap framebuffer W/C

    Some platforms (such as SBSA-QEMU on recent builds of the emulator) only
    tolerate misaligned accesses to normal memory, and raise alignment
    faults on such accesses to device memory, which is the default for PCIe
    MMIO BARs.

    When emulating a PCIe graphics controller, the framebuffer is typically
    exposed via a MMIO BAR, while the disposition of the region is closer to
    memory (no side effects on reads or writes, except for the changing
    picture on the screen; direct random access to any pixel in the image).

    In order to permit the use of such controllers on platforms that only
    tolerate these types of accesses for normal memory, it is necessary to
    remap the memory. Use the DXE services to set the desired capabilities
    and attributes.

    Hide this behavior under a feature PCD so only platforms that really
    need it can enable it. (OVMF on x86 has no need for this)

With this fix enabled we can boot sbsa-ref with more than one cpu core.

target/i386: Advertise MWAIT iff host supports

host_cpu_realizefn() sets CPUID_EXT_MONITOR without consulting host/KVM
capabilities. This may cause problems:

- If MWAIT/MONITOR is not available on the host, advertising this

  triggers #UD and the guest doesn't boot.  This is because typically
  #UD takes priority over VM-Exit interception checks and KVM doesn't
  emulate MONITOR/MWAIT on #UD.

- If KVM doesn't support KVM_X86_DISABLE_EXITS_MWAIT, MWAIT/MONITOR
  from the guest are intercepted by KVM, which is not what cpu-pm=on
  intends to do.

In these cases, MWAIT/MONITOR should not be exposed to the guest.

The logic in kvm_arch_get_supported_cpuid() to handle CPUID_EXT_MONITOR
is correct and sufficient, and we can't set CPUID_EXT_MONITOR after
x86_cpu_filter_features().

This was not an issue before commit 662175b91ff ("i386: reorder call to
cpu_exec_realizefn") because the feature added in the accel-specific
realizefn could be checked against host availability and filtered out.

Additionally, it seems not a good idea to handle guest CPUID leaves in
host_cpu_realizefn(), and this patch merges host_cpu_enable_cpu_pm()
into kvm_cpu_realizefn().

vl: Allow multiple -overcommit commands

Both cpu-pm and mem-lock are related to system resource overcommit, but
they are separate from each other, in terms of how they are realized,
and of course, they are applied to different system resources.

It's tempting to use separate command lines to specify their behavior.
e.g., in the following example, the cpu-pm command is quietly
overwritten, and it's not easy to notice it without careful inspection.

  --overcommit mem-lock=on
  --overcommit cpu-pm=on

include: move typeof_strip_qual to compiler.h, use it in QAPI_LIST_LENGTH()

The typeof_strip_qual() is most useful for the atomic fetch-and-modify
operations in atomic.h, but it can be used elsewhere as well.  For example,
QAPI_LIST_LENGTH() assumes that the argument is not const, which is not a
requirement.

Move the macro to compiler.h and, while at it, move it under #ifndef
__cplusplus to emphasize that it uses C-only constructs.  A C++ version
of typeof_strip_qual() using type traits is possible[1], but beyond the
scope of this patch because the little C++ code that is in QEMU does not
use QAPI.

The patch was tested by changing the declaration of strv_from_str_list()
in qapi/qapi-type-helpers.c to:

    char **strv_from_str_list(const strList *const list)

This is valid C code, and it fails to compile without this change.
