Subject: [PATCH 0/5] megaraid_sas: scsi-mq support
Date: Fri, 11 Nov 2016 10:44:47 +0100	[thread overview]
Message-ID: <1478857492-4581-1-git-send-email-hare@suse.de> (raw)

Hi all,

here's the patcheset to enable scsi-mq support for megaraid_sas.
It's based on hch's irq rework currently pending in tip.
As the overall results have been less then stellar (see the thread
'reduced latency is killing performance') I've also added a module
parameter 'use_blk_mq' to allowing to switch off scsi-mq support
on a per-driver basis.

Hannes Reinecke (5):
  megaraid_sas: switch to pci_alloc_irq_vectors
  megaraid_sas: avoid calling megasas_lookup_instance()
  megaraid_sas: do not crash on invalid completion
  megaraid_sas: scsi-mq support
  megaraid_sas: add mmio barrier after register writes
