• 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.

• c00539037   blk-mq-pci: add a fallback when pci_irq_get_affinity returns NULL ... Browse Code »

  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.
