2ada4b63f1 migration/rdma: zore out head.repeat to make the error more clear
Previously, we got a confusion error that complains
the RDMAControlHeader.repeat:
qemu-system-x86_64: rdma: Too many requests in this message (3638950032).Bailing.

Actually, it's caused by an unexpected RDMAControlHeader.type.
After this patch, error will become:
qemu-system-x86_64: Unknown control message QEMU FILE

8ebcb4b312 MAINTAINERS: Add entry for rdma migration
It's not obvious to many that RDMA migration is in Odd Fixes stage for a
long time.  Add an explicit sub entry for it (besides migration, which
already covers the rdma files) to be clear on that, meanwhile add Zhijian
as Reviewer, so Zhijian can see the patches and review when he still has
the bandwidth.

848a050342 migration: Update error description outside migration.c
A few code paths exist in the source code,where a migration is
marked as failed via MIGRATION_STATUS_FAILED, but the failure happens
outside	of migration.c

In such	cases, an error_report() call is made, however the current
MigrationState is never	updated	with the error description, and	hence
clients	like libvirt never know	the actual reason for the failure.

This patch covers such cases outside of	migration.c and	updates	the
error description at the appropriate places.

969298f9d7 migration/vmstate: Introduce vmstate_save_state_with_err
Currently, a few code paths exist in the function vmstate_save_state_v,
which ultimately leads to a migration failure. However, an update in the
current MigrationState for the error description is never done.

vmstate.c somehow doesn't seem to allow	the use	of migrate_set_error due
to some	dependencies for unit tests. Hence, this patch introduces a new
function vmstate_save_state_with_err, which will eventually propagate
the error message to savevm.c where a migrate_set_error	call can be
eventually done.

The virtio_list duplicates information about virtio devices that already

realized virtio devices, search the QOM composition tree instead.

This patch modifies the QMP command qmp_x_query_virtio to instead
recursively search the QOM composition tree for devices of type
'TYPE_VIRTIO_DEVICE'. The device is also checked to ensure it's

b0de17a2e2 vhost: Add count argument to vhost_svq_poll()
Next patches in this series will no longer perform an
immediate poll and check of the device's used buffers
for each CVQ state load command. Instead, they will
send CVQ state load commands in parallel by polling
multiple pending buffers at once.

To achieve this, this patch refactoring vhost_svq_poll()
to accept a new argument `num`, which allows vhost_svq_poll()
to wait for the device to use multiple elements,
rather than polling for a single element.

6c4825476a vdpa: move vhost_vdpa_set_vring_ready to the caller
Doing that way allows CVQ to be enabled before the dataplane vqs,
restoring the state as MQ or MAC addresses properly in the case of a
migration.

The patch does it by defining a ->load NetClientInfo callback also for
dataplane.  Ideally, this should be done by an independent patch, but
the function is already static so it would only add an empty
vhost_vdpa_net_data_load stub.

b40eba9cdd vdpa: use first queue SVQ state for CVQ default
Previous to this patch the only way CVQ would be shadowed is if it does
support to isolate CVQ group or if all vqs were shadowed from the
beginning.  The second condition was checked at the beginning, and no
more configuration was done.

After this series we need to check if data queues are shadowed because
they are in the middle of the migration.  As checking if they are
shadowed already covers the previous case, let's just mimic it.

43d6376980 virtio: don't zero out memory region cache for indirect descriptors
Lots of virtio functions that are on a hot path in data transmission
are initializing indirect descriptor cache at the point of stack
allocation.  It's a 112 byte structure that is getting zeroed out on
each call adding unnecessary overhead.  It's going to be correctly
initialized later via special init function.  The only reason to
actually initialize right away is the ability to safely destruct it.
Replacing a designated initializer with a function to only initialize
what is necessary.

Removal of the unnecessary stack initializations improves throughput
of virtio-net devices in terms of 64B packets per second by 6-14 %
depending on the case.  Tested with a proposed af-xdp network backend
and a dpdk testpmd application in the guest, but should be beneficial
for other virtio devices as well.

is equivalent to:

from which the other vhost-user stub can specialise.

961d60e934 hw/virtio: Propagate page_mask to vhost_vdpa_listener_skipped_section()
In order to make vhost-vdpa.c a target-agnostic source unit,
we need to remove the TARGET_PAGE_SIZE / TARGET_PAGE_MASK /
TARGET_PAGE_ALIGN uses. TARGET_PAGE_SIZE will be replaced by
the runtime qemu_target_page_size(). The other ones will be
deduced from TARGET_PAGE_SIZE.

Since the 3 macros are used in 3 related functions (sharing
the same call tree), we'll refactor them to only depend on
TARGET_PAGE_MASK.

Having the following call tree:

  vhost_vdpa_listener_region_del()
    -> vhost_vdpa_listener_skipped_section()
       -> vhost_vdpa_section_end()

The first step is to propagate TARGET_PAGE_MASK to
vhost_vdpa_listener_skipped_section().
