Add feature 'deprecated' to the deprecated QMP commands, so their
deprecation becomes visible in output of query-qmp-schema. Looks like
this:
{"name": "query-cpus",
"ret-type": "[164]",
"meta-type": "command",
"arg-type": "0",
---> "features": ["deprecated"]}
Management applications could conceivably use this for static
checking.
The deprecated commands are change, cpu-add, migrate-set-cache-size,
migrate_set_downtime, migrate_set_speed, query-cpus, query-events,
query-migrate-cache-size.
The deprecated command arguments are block-commit arguments @base and
@top, and block_set_io_throttle, blockdev-change-medium,
blockdev-close-tray, blockdev-open-tray, eject argument @device.
The deprecated command results are query-cpus-fast result @arch,
query-block result @dirty-bitmaps, query-named-block-nodes result
@encryption_key_missing and result @dirty-bitmaps's member @status.
Same for query-block result @inserted, which mirrors
query-named-block-nodes.

# @LostTickPolicy:

# Policy for handling lost ticks in timer devices. Ticks end up getting
|
|
# lost when, for example, the guest is paused.
|
|
#
|
|
# @discard: throw away the missed ticks and continue with future injection
|
|
# normally. The guest OS will see the timer jump ahead by a
|
|
# potentially quite significant amount all at once, as if the
|
|
# intervening chunk of time had simply not existed; needless to
|
|
# say, such a sudden jump can easily confuse a guest OS which is
|
|
# not specifically prepared to deal with it. Assuming the guest
|
|
# OS can deal correctly with the time jump, the time in the guest
|
|
# and in the host should now match.
|
|
#
|
|
# @delay: continue to deliver ticks at the normal rate. The guest OS will
|
|
# not notice anything is amiss, as from its point of view time will
|
|
# have continued to flow normally. The time in the guest should now
|
|
# be behind the time in the host by exactly the amount of time during
|
|
# which ticks have been missed.
|
|
#
|
|
# @slew: deliver ticks at a higher rate to catch up with the missed ticks.
|
|
# The guest OS will not notice anything is amiss, as from its point
|
|
# of view time will have continued to flow normally. Once the timer
|
|
# has managed to catch up with all the missing ticks, the time in
|
|
# the guest and in the host should match.
