• 843477d4c   blk-mq: initial support for multiple queue maps ... Browse Code »

  Add a queue offset to the tag map. This enables users to map
  iteratively, for each queue map type they support.

  Bump maximum number of supported maps to 2, we're now fully
  able to support more than 1 map.

• 0da73d00c   blk-mq: code clean-up by adding an API to clear set->mq_map ... Browse Code »

  set->mq_map is now currently cleared if something goes wrong when
  establishing a queue map in blk-mq-pci.c. It's also cleared before
  updating a queue map in blk_mq_update_queue_map().

  This patch provides an API to clear set->mq_map to make it clear.

• f23f5bece   blk-mq: Allow PCI vector offset for mapping queues ... Browse Code »

  The PCI interrupt vectors intended to be associated with a queue may
  not start at 0; a driver may allocate pre_vectors for special use. This
  patch adds an offset parameter so blk-mq may find the intended affinity
  mask and updates all drivers using this API accordingly.

  While pci_irq_get_affinity should never fail for SMP kernel that
  implement the affinity mapping, it will always return NULL in the
  UP case, so provide a fallback mapping of all queues to CPU 0 in
  that case.
