When doing device assignment of a physical device, MSI-X can be
enabled with no vectors enabled and this sets the IRQ index to
VFIO_PCI_MSIX_IRQ_INDEX. However, when MSI-X is disabled, the IRQ
index is left untouched if no vectors are in use. Then, when INTx
is enabled, the IRQ index value is considered incompatible (set to
MSI-X) and VFIO_DEVICE_SET_IRQS fails. QEMU complains with :
qemu-system-x86_64: vfio 0000:08:00.0: Failed to set up TRIGGER eventfd signaling for interrupt INTX-0: VFIO_DEVICE_SET_IRQS failure: Invalid argument
To avoid that, unconditionaly clear the IRQ index when MSI-X is
disabled.

We're currently allowing the process_incoming_migration_bh bottom-half
to run without holding a reference to the 'current_migration' object,
which leads to a segmentation fault if the BH is still live after
migration_shutdown() has dropped the last reference to
current_migration.
In my system the bug manifests as migrate_multifd() returning true
when it shouldn't and multifd_load_shutdown() calling
multifd_recv_terminate_threads() which crashes due to an uninitialized
multifd_recv_state.
Fix the issue by holding a reference to the object when scheduling the
BH and dropping it before returning from the BH. The same is already
done for the cleanup_bh at migrate_fd_cleanup_schedule().

Stop using outside knowledge about the io channels when registering
yank functions. Query for features instead.
The yank method for all channels used with migration code currently is
to call the qio_channel_shutdown() function, so query for
QIO_CHANNEL_FEATURE_SHUTDOWN. We could add a separate feature in the
future for indicating whether a channel supports yanking, but that
seems overkill at the moment.

[peterx: use _SKIPPED rather than _OPTIONAL]
Signed-off-by: Peter Xu <peterx@redhat.com>
The migration tests have support for being passed two QEMU binaries to
test migration compatibility.
Add a CI job that builds the lastest release of QEMU and another job
that uses that version plus an already present build of the current
version and run the migration tests with the two, both as source and
destination. I.e.:
old QEMU (n-1) -> current QEMU (development tree)
current QEMU (development tree) -> old QEMU (n-1)
The purpose of this CI job is to ensure the code we're about to merge
will not cause a migration compatibility problem when migrating the
next release (which will contain that code) to/from the previous
release.
The version of migration-test used will be the one matching the older
QEMU. That way we can avoid special-casing new tests that wouldn't be
compatible with the older QEMU.
Note: for user forks, the version tags need to be pushed to gitlab
otherwise it won't be able to checkout a different version.

When the migration frameworks fetches the exact pending sizes, it means
this check:
remaining_size < s->threshold_size
Must have been done already, actually at migration_iteration_run():
if (must_precopy <= s->threshold_size) {
qemu_savevm_state_pending_exact(&must_precopy, &can_postcopy);
That should be after one round of ram_state_pending_estimate(). It makes
the 2nd check meaningless and can be dropped.
To say it in another way, when reaching ->state_pending_exact(), we
unconditionally sync dirty bits for precopy.
Then we can drop migrate_get_current() there too.

The const_le64() macro introduced in commit 845d80a8c7 turns out
to have a bug which means that on big-endian systems the compiler
complains if the argument isn't already a 64-bit type. This hasn't
caused a problem yet, because there are no in-tree uses, but it
means it's not possible for anybody to add one without it failing CI.
This example is from an attempted use of it with the argument '0',
from the s390 CI runner's gcc:
../block/blklogwrites.c: In function ‘blk_log_writes_co_do_log’:

Fix this by making all the constants in the macro have the ULL
suffix. This will cause them all to be 64-bit integers, which means
the result of the logical & will also be an unsigned 64-bit type,
even if the input to the macro is a smaller type, and so the shifts
will be in range.

In commit 1b7bc9b5c8 we changed handle_vec_simd_sqshrn() so
that instead of starting with a 0 value and depositing in each new
element from the narrowing operation, it instead started with the raw
result of the narrowing operation of the first element.
This is fine in the vector case, because the deposit operations for
the second and subsequent elements will always overwrite any higher
bits that might have been in the first element's result value in
tcg_rd. However in the scalar case we only go through this loop
once. The effect is that for a signed narrowing operation, if the
result is negative then we will now return a value where the bits
above the first element are incorrectly 1 (because the narrowfn
returns a sign-extended result, not one that is truncated to the
element size).
Fix this by using an extract operation to get exactly the correct
bits of the output of the narrowfn for element 1, instead of a
plain move.

This patch implements a 32 half word FIFO as per imx serial device
specifications. If a non empty FIFO is below the trigger level, an
ageing timer will tick for a duration of 8 characters. On expiry,
AGTIM will be set triggering an interrupt. AGTIM timer resets when
there is activity in the receive FIFO.
Otherwise, RRDY is set when trigger level is exceeded. The receive
trigger level is 8 in newer kernel versions and 1 in older ones.

Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected
memory ranges were covered by the unimplemented DAP device. The commit
reduced the DAP address range from 0x100000 to 4kB, and the emulation

Various files in hw/arm/ don't require "cpu.h" anymore.
Except virt-acpi-build.c, all of them don't require any
ARM specific knowledge anymore and can be build once as
target agnostic units. Update meson accordingly.

Move Arm A-class Generic Timer definitions to the new
"target/arm/gtimer.h" header so units in hw/ which don't
need access to ARMCPU internals can use them without
having to include the huge "cpu.h".

e2h_access() was added in commit bb5972e439 ("target/arm:
Add VHE timer register redirection and aliasing") close to
the generic_timer_cp_reginfo[] array, but isn't used until
vhe_reginfo[] definition. Move it closer to the other e2h
helpers.

The ARM_CPU_IRQ/FIQ definitions are used to index the GPIO
IRQ created calling qdev_init_gpio_in() in ARMCPU instance_init()
handler. To allow non-ARM code to raise interrupt on ARM cores,
move they to 'target/arm/cpu-qom.h' which is non-ARM specific and
can be included by any hw/ file.
File list to include the new header generated using:
$ git grep -wEl 'ARM_CPU_(\w*IRQ|FIQ)'

Now than we can access the M-profile bank index
definitions from the target-agnostic "cpu-qom.h"
header, we don't need the huge "cpu.h" anymore
(except in hw/arm/armv7m.c). Reduce its inclusion
to the source unit.

The ARMv7M QDev container accesses the QDev SysTickState
by its secure/non-secure bank index. In order to make
the "hw/intc/armv7m_nvic.h" header target-agnostic in
the next commit, first move the M-profile bank index
definitions to "target/arm/cpu-qom.h".

"target/arm/cpu.h" is target specific, any file including it
becomes target specific too, thus this is the same for any file
including "hw/misc/xlnx-versal-crl.h".
"hw/misc/xlnx-versal-crl.h" doesn't require any target specific
definition however, only the target-agnostic QOM definitions
from "target/arm/cpu-qom.h". Include the latter header to avoid
tainting unnecessary objects as target-specific.
