[PATCH 0/5] libsas fixes discovered via isci-atapi enabling effort

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



While enabling atapi device support for isci we encountered a condition
whereby multiple srX devices (one for every possible LUN) were exported
by the midlayer.  Looking at other drivers showed that they had a local
workaround for this and other conditions in custom
->slave_{alloc|configure} methods.  Rather than add custom workaround
for isci this patchset uplevels those workarounds to libsas proper.

Patch 3/5 is tagged RFC as I do not know the original history behind
hard limiting libsas end devices to a queue_depth of 32.  At least mvsas
has been bumping this up to 64 on its own.

      libsas: disable scanning lun > 0 on ata devices
      libsas: fix ->change_queue_{depth|type} for sata devices
      libsas: dynamic queue depth
      mvsas: remove mvs_slave_{alloc|configure}
      pm8001: remove pm8001_slave_{alloc|configure}
