scsi: hpsa: remove abort handler

2017-06-13T00:48:01+00:00

- simplify the driver - there are a lot of quirky racy conditions not handled - causes more aborts/resets when the number of commands to be aborted is large, such as in multi-path fail-overs. - has been turned off in our internal driver since 8/31/2015 Reviewed-by: Scott Benesh Reviewed-by: Scott Teel Reviewed-by: Kevin Barnett Signed-off-by: Don Brace Signed-off-by: Martin K.

scsi: hpsa: separate monitor events from rescan worker

2017-06-13T00:48:01+00:00

create new worker thread to monitor controller events - both the rescan and event monitor workers can cause a rescan to occur however for multipath we have found that we need to respond faster than the normal scheduled rescan interval for path fail-overs. - getting controller events only involves reading a register, but the rescan worker can obtain an updated LUN list when there is a PTRAID device present. - move common code to a separate function. advantages: - detect controller events more frequently. - leave rescan thread interval at 30 seconds.

Pull SCSI updates from James Bottomley: "This update includes the usual round of major driver updates (ncr5380, lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas). There's also an assortment of minor fixes, mostly in error legs or other not very user visible stuff. The major change is the pci_alloc_irq_vectors replacement for the old pci_msix_.. calls; this effectively makes IRQ mapping generic for the drivers and allows blk_mq to use the information" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (256 commits) scsi: qla4xxx: switch to pci_alloc_irq_vectors scsi: hisi_sas: support deferred probe for v2 hw scsi: megaraid_sas: switch to pci_alloc_irq_vectors scsi: scsi_devinfo: remove synchronous ALUA for NETAPP devices scsi: be2iscsi: set errno on error path scsi: be2iscsi: set errno on error path scsi: hpsa: fallback to use legacy REPORT PHYS command scsi: scsi_dh_alua: Fix RCU annotations scsi: hpsa: use %phN for short hex dumps scsi: hisi_sas: fix free'ing in probe and remove scsi: isci: switch to pci_alloc_irq_vectors scsi: ipr: Fix runaway IRQs when falling back from MSI to LSI scsi: dpt_i2o: double free on error path scsi: cxlflash: Migrate scsi command pointer to AFU command scsi: cxlflash: Migrate IOARRIN specific routines to function pointers scsi: cxlflash: Cleanup queuecommand() scsi: cxlflash: Cleanup send_tmf() scsi: cxlflash: Remove AFU command lock scsi: cxlflash: Wait for active AFU commands to timeout upon tear down scsi: cxlflash: Remove private command pool ...

scsi: hpsa: use bus '3' for legacy HBA devices

2016-11-22T22:17:55+00:00

Older controllers use SCSI target id '0' for the first internal disk. As the controllers are now placed on the same bus as the internal disks this leads to a clash with the SCSI target id of controller. This patch checks the SCSI revision, and moves older controller to bus '3' to be compatible with older releases and avoid this problem.

scsi: hpsa: use pci_alloc_irq_vectors and automatic irq affinity

2016-11-12T15:11:06+00:00

This patch converts over hpsa to use the pci_alloc_irq_vectors including the PCI_IRQ_AFFINITY flag that automatically assigns spread out irq affinity to the I/O queues. It also cleans up the per-ctrl interrupt state due to the use of the pci_irq_vector and pci_free_irq_vectors helpers that don't need to know the exact irq type. Additionally it changes a little oddity in the existing code that was using different array indixes into the per-vector arrays depending on whether a controller is using a single INTx or single MSI irq.
