[Qemu-devel] [PATCH v5 0/6] add throttle block driver filter

Posted by Manos Pitsidianakis 6 years, 8 months ago

This series adds a throttle block driver filter. Currently throttling is done
at the BlockBackend level. Using block driver interfaces we can move the
throttling to any point in the BDS graph using a throttle node which uses the
existing throttling code. This allows for potentially more complex
configurations (throttling at any point in the graph, chained filters)

v5:
  fix crash in 'add aio_context field in ThrottleGroupMember'
  fix suggestions in block/throttle.c

v4:
  fix suggestions in block/throttle.c
  fix suggestions in block/throttle_groups.c
  add doc note in BlockDevOptionsThrottle

v3:
  fix style error in 'add aio_context field in ThrottleGroupMember'

v2:
  change QOM throttle group object name
  print valid ranges for uint on error
  move frees in throttle_group_obj_finalize()
  split throttle_group_{set,get}()
  add throttle_recurse_is_first_non_filter()

Manos Pitsidianakis (6):
  block: move ThrottleGroup membership to ThrottleGroupMember
  block: add aio_context field in ThrottleGroupMember
  block: tidy ThrottleGroupMember initializations
  block: convert ThrottleGroup to object with QOM
  block: add throttle block filter driver
  block: add iotest 184 for the throttle filter driver
