26a09ead73 tests/tcg/s390x: Allow specifying extra QEMU options on the command line
The use case for this is `make check-tcg EXTFLAGS="-accel kvm"`,
which allows validating the system TCG testcases on real hardware.
EXTFLAGS name is borrowed from tests/tcg/xtensa/Makefile.softmmu-target.
While at it, use += instead of = in order to be consistent with the
other architectures.

e08f6e0b9f tests/qtest/x86: check for availability of older cpu models before running tests
It is better to check if some older cpu models like 486, athlon, pentium,
penryn, phenom, core2duo etc are available before running their corresponding
tests. Some downstream distributions may no longer support these older cpu
models.

Signature of add_feature_test() has been modified to return void as
FeatureTestArgs* was not used by the caller.

One minor correction. Replaced 'phenom' with '486' in the test
'x86/cpuid/auto-level/phenom/arat' matching the cpu used.

f43f8abe45 tests/qtest/libqtest: add qtest_has_cpu_model() api
Added a new test api qtest_has_cpu_model() in order to check availability of
some cpu models in the current QEMU binary. The specific architecture of the
QEMU binary is selected using the QTEST_QEMU_BINARY environment variable.
This api would be useful to run tests against some older cpu models after
checking if QEMU actually supported these models.

af206c284e block/crypto: create ciphers on demand
Ciphers are pre-allocated by qcrypto_block_init_cipher() depending on
the given number of threads. The -device
virtio-blk-pci,iothread-vq-mapping= feature allows users to assign
multiple IOThreads to a virtio-blk device, but the association between
the virtio-blk device and the block driver happens after the block
driver is already open.

When the number of threads given to qcrypto_block_init_cipher() is
smaller than the actual number of threads at runtime, the
block->n_free_ciphers > 0 assertion in qcrypto_block_pop_cipher() can
fail.

Get rid of qcrypto_block_init_cipher() n_thread's argument and allocate
ciphers on demand.

24687abf23 linux-aio: add IO_CMD_FDSYNC command support
Libaio defines IO_CMD_FDSYNC command to sync all outstanding
asynchronous I/O operations, by flushing out file data to the
disk storage. Enable linux-aio to submit such aio request.

When using aio=native without fdsync() support, QEMU creates
pthreads, and destroying these pthreads results in TLB flushes.
In a real-time guest environment, TLB flushes cause a latency
spike. This patch helps to avoid such spikes.

10b1e09ed3 block/copy-before-write: use uint64_t for timeout in nanoseconds
rather than the uint32_t for which the maximum is slightly more than 4
seconds and larger values would overflow. The QAPI interface allows
specifying the number of seconds, so only values 0 to 4 are safe right
now, other values lead to a much lower timeout than a user expects.

The block_copy() call where this is used already takes a uint64_t for
the timeout, so no change required there.

e669e800fc aio: warn about iohandler_ctx special casing
The main loop has two AioContexts: qemu_aio_context and iohandler_ctx.
The main loop runs them both, but nested aio_poll() calls on
qemu_aio_context exclude iohandler_ctx.

Which one should qemu_get_current_aio_context() return when called from
the main loop? Document that it's always qemu_aio_context.

This has subtle effects on functions that use
qemu_get_current_aio_context(). For example, aio_co_reschedule_self()
does not work when moving from iohandler_ctx to qemu_aio_context because
qemu_get_current_aio_context() does not differentiate these two
AioContexts.

Document this in order to reduce the chance of future bugs.

719c6819ed Revert "monitor: use aio_co_reschedule_self()"
Commit 1f25c172f8 ("monitor: use aio_co_reschedule_self()") was a code
cleanup that uses aio_co_reschedule_self() instead of open coding
coroutine rescheduling.

Bug RHEL-34618 was reported and Kevin Wolf <kwolf@redhat.com> identified
the root cause. I missed that aio_co_reschedule_self() ->
qemu_get_current_aio_context() only knows about
qemu_aio_context/IOThread AioContexts and not about iohandler_ctx. It
does not function correctly when going back from the iohandler_ctx to
qemu_aio_context.

Go back to open coding the AioContext transitions to avoid this bug.

This reverts commit 1f25c172f8.

rvalue. Upon first call, the list of arguments which might need
initialization init_list is freed to indicate that they have been
processed. For instructions without an rvalue predicate,
gen_inst_init_args() isn't called and init_list will never be freed.

Free init_list from free_instruction() if it hasn't already been freed.
A comment in free_instruction is also updated.

49c1f7a472 target/hexagon: idef-parser remove unused defines
Before switching to GArray/g_string_printf we used fixed size arrays for
output buffers and instructions arguments among other things.

Macros defining the sizes of these buffers were left behind, remove
them.

The Hexagon Programmer's Reference Manual says that the exception 0x1e
should be raised upon an unaligned program counter. Let's implement that

a1852002c7 Hexagon: fix HVX store new
At 09a7e7db0f (Hexagon (target/hexagon) Remove uses of
op_regs_generated.h.inc, 2024-03-06), we've changed the logic of
check_new_value() to use the new pre-calculated
packet->insn[...].dest_idx instead of calculating the index on the fly
using opcode_reginfo[...]. The dest_idx index is calculated roughly like
the following:

    for reg in iset[tag]["syntax"]:
        if reg.is_written():
            dest_idx = regno
            break

Thus, we take the first register that is writtable. Before that,
however, we also used to follow an alphabetical order on the register
type: 'd', 'e', 'x', and 'y'. No longer following that makes us select
the wrong register index and the HVX store new instruction does not
update the memory like expected.

fc00123f3a python: mkvenv: remove ensure command
This was used to bootstrap the venv with a TOML parser, after which
ensuregroup is used.  Now that we expect it to be present as a system
package (either tomli or, for Python 3.11, tomllib), it is not needed
anymore.

Note that this means that, when implemented, the hypothetical "isolated"
mode that does not use any system packages will only work with Python
3.11+.

1f97715c83 Revert "python: use vendored tomli"
Now that Ubuntu 20.04 is not included anymore, there is no need to ship
it as part of QEMU; Ubuntu 22.04 includes it and Leap users anyway
need to install all the required dependencies from PyPI.

This mostly reverts commit ec77ee7634de123b7c899739711000fd21dab68b,
with just some changes to the wording.

1ea1432199 i386: Add support for overflow recovery
Add cpuid bit definition for overflow recovery. This is needed in the case
where a deferred error has been sent to the guest, a guest process accesses the
poisoned memory, but the machine_check_poll function has not yet handled the
original deferred error. If overflow recovery is not set in this case, when we
handle the uncorrected error from the poisoned memory access, the overflow bit
will be set and will result in the guest being shut down.

By the time the MCE reaches the guest, the overflow has been handled
by the host and has not caused a shutdown, so include the bit unconditionally.

  - Add "succor" feature word.
  - Add case to kvm_arch_get_supported_cpuid for the SUCCOR feature.

4b77512b27 i386: Fix MCE support for AMD hosts
For the most part, AMD hosts can use the same MCE injection code as Intel, but
there are instances where the qemu implementation is Intel specific. First, MCE
delivery works differently on AMD and does not support broadcast. Second,
kvm_mce_inject generates MCEs that include a number of Intel specific status
bits. Modify kvm_mce_inject to properly generate MCEs on AMD platforms.

888788dd76 docs: i386: pc: Avoid mentioning limit of maximum vCPUs
Different versions of PC machine support different maximum vCPUs, and
even different features have limits on the maximum number of vCPUs (
For example, if x2apic is not enabled in the TCG case, the maximum of
255 vCPUs are supported).

It is difficult to list the maximum vCPUs under all restrictions. Thus,
to avoid confusion, avoid mentioning specific maximum vCPU number
limitations here.
