Rename vfio_pci_hot_reset to vfio_legacy_pci_hot_reset and move it

Some vIOMMU such as virtio-iommu use IOVA ranges from host side to
setup reserved ranges for passthrough device, so that guest will not
use an IOVA range beyond host support.
Use an uAPI of IOMMUFD to get IOVA ranges of host side and pass to

64bit IOVA range.
Also use out_iova_alignment returned from uAPI as pgsizes instead of

Before 732d548732ed, this was implicitly done via truncation to

To fix this, we must add conditional zero-extensions.

i386/sev: Avoid SEV-ES crash due to missing MSR_EFER_LMA bit
Commit 7191f24c7fcf ("accel/kvm/kvm-all: Handle register access errors")
added error checking for KVM_SET_SREGS/KVM_SET_SREGS2. In doing so, it
exposed a long-running bug in current KVM support for SEV-ES where the
kernel assumes that MSR_EFER_LMA will be set explicitly by the guest
kernel, in which case EFER write traps would result in KVM eventually
seeing MSR_EFER_LMA get set and recording it in such a way that it would
be subsequently visible when accessing it via KVM_GET_SREGS/etc.
However, guest kernels currently rely on MSR_EFER_LMA getting set
automatically when MSR_EFER_LME is set and paging is enabled via
CR0_PG_MASK. As a result, the EFER write traps don't actually expose the
MSR_EFER_LMA bit, even though it is set internally, and when QEMU
subsequently tries to pass this EFER value back to KVM via
KVM_SET_SREGS* it will fail various sanity checks and return -EINVAL,
which is now considered fatal due to the aforementioned QEMU commit.
This can be addressed by inferring the MSR_EFER_LMA bit being set when
paging is enabled and MSR_EFER_LME is set, and synthesizing it to ensure
the expected bits are all present in subsequent handling on the host
side.
Ultimately, this handling will be implemented in the host kernel, but to
avoid breaking QEMU's SEV-ES support when using older host kernels, the
same handling can be done in QEMU just after fetching the register
values via KVM_GET_SREGS*. Implement that here.

KVM_RISCV_GET_CSR() and KVM_RISCV_SET_CSR() use an 'int ret' variable

The result is that the compiler is less than pleased and is pointing

The macros are doing early returns for non-zero returns and the local
'ret' variable for both functions is used just to do 'return 0', so
remove them from kvm_riscv_get_regs_csr() and kvm_riscv_put_regs_csr()
and do a straight 'return 0' in the end.
For good measure let's also rename the 'ret' variables in
KVM_RISCV_GET_CSR() and KVM_RISCV_SET_CSR() to '_ret' to make them more
resilient to these kind of errors.

QEMU crashes on exit when a virtio-sound device has failed to
realise. Its vmstate field was not cleaned up properly with
qemu_del_vm_change_state_handler().
This patch changes the realize() order as
1. Validate the given configuration values (no resources allocated
by us either on success or failure)
2. Try AUD_register_card() and return on failure (no resources allocated
by us on failure)
3. Initialize vmstate, virtio device, heap allocations and stream
parameters at once.
If error occurs, goto error_cleanup label which calls
virtio_snd_unrealize(). This cleans up all resources made in steps
1-3.
AUD_register_card might fail. Even though errp was passed as an

tests/acpi/bios-tables-test: do not write new blobs unless there are changes
When dumping table blobs using rebuild-expected-aml.sh, table blobs from all
test variants are dumped regardless of whether there are any actual changes to
the tables or not. This creates lot of new files for various test variants that
are not part of the git repository. This is because we do not check in all table
blobs for all test variants into the repository. Only those blobs for those
variants that are different from the generic test-variant agnostic blob are
checked in.
This change makes the test smarter by checking if at all there are any changes
in the tables from the checked-in gold master blobs and take actions
accordingly.
When there are no changes:
- No new table blobs would be written.
- Existing table blobs will be refreshed (git diff will show no changes).
When there are changes:
- New table blob files will be dumped.
- Existing table blobs will be refreshed (git diff will show that the files
changed, asl diff will show the actual changes).
When new tables are introduced:
- Zero byte empty file blobs for new tables as instructed in the header of
bios-tables-test.c will be regenerated to actual table blobs.
This would make analyzing changes to tables less confusing and there would
be no need to clean useless untracked files when there are no table changes.

docs/devel: rationalise unstable gitlab tests under FLAKY_TESTS
It doesn't make sense to have two classes of flaky tests. While it may
take the constrained environment of CI to trigger failures easily it
doesn't mean they don't occasionally happen on developer machines. As
CI is the gating factor to passing there is no point developers
running the tests locally anyway unless they are trying to fix things.
While we are at it update the language in the docs to discourage the
QEMU_TEST_FLAKY_TESTS becoming a permanent solution.

The machine uses a modified U-Boot under GPL license but the sources

when calling a boot loader directly and thus simplifying booting
guests. We need a small routine that AmigaOS calls from ROM which is

migration: free 'saddr' since be no longer used
Since socket_parse() will allocate memory for 'saddr',and its value
will pass to 'addr' that allocated by migrate_uri_parse(),
then 'saddr' will no longer used,need to free.
But due to 'saddr->u' is shallow copying the contents of the union,
the members of this union containing allocated strings,and will be used after that.
So just free 'saddr' itself without doing a deep free on the contents of the SocketAddress.

export/vhost-user-blk: Fix consecutive drains
The vhost-user-blk export implement AioContext switches in its drain
implementation. This means that on drain_begin, it detaches the server
from its AioContext and on drain_end, attaches it again and schedules
the server->co_trip coroutine in the updated AioContext.
However, nothing guarantees that server->co_trip is even safe to be
scheduled. Not only is it unclear that the coroutine is actually in a
state where it can be reentered externally without causing problems, but
with two consecutive drains, it is possible that the scheduled coroutine
didn't have a chance yet to run and trying to schedule an already
scheduled coroutine a second time crashes with an assertion failure.
Following the model of NBD, this commit makes the vhost-user-blk export
shut down server->co_trip during drain so that resuming the export means
creating and scheduling a new coroutine, which is always safe.
There is one exception: If the drain call didn't poll (for example, this
happens in the context of bdrv_graph_wrlock()), then the coroutine
didn't have a chance to shut down. However, in this case the AioContext
can't have changed; changing the AioContext always involves a polling
drain. So in this case we can simply assert that the AioContext is
unchanged and just leave the coroutine running or wake it up if it has
yielded to wait for the AioContext to be attached again.
