pm80xx: Don't override ts->stat on IO_OPEN_CNX_ERROR_HW_RESOURCE_BUSY

2015-09-06T18:53:31+00:00

In case psataPayload->status has a status of IO_OPEN_CNX_ERROR_HW_RESOURCE_BUSY
ts->stat gets set to SAS_OPEN_REJECT but a missing 'break' statement causes a
fallthrough to the default handler of the switch statement overriding ts->stat
to SAS_DEV_NO_RESPONSE.

pm80xx: Add PORT RECOVERY TIMEOUT support

2015-08-27T00:17:52+00:00

PORT RECOVERY TIMEOUT is the maximum time between the controller's
detection of the PHY down until the receipt of the ID_Frame (from the
same remote SAS port). If the time expires before the ID_FRAME is
received, the port is considered INVALID and can be removed. The
IOP_EVENT_PORT_RECOVERY_TIMER_TMO event is reported following the
IOP_EVENT_ PHY_DOWN event when the PHY/port does not recover after
Port Recovery Time.

pm80xx: Remove unnecessary phy disconnect while link error

2015-08-27T00:17:05+00:00

If the link error happens, we don't need to disconnect the phy,
which will remove the drive. Instead acknowledging the controller
and logging the error will be enough.

pm80xx: Fix for Incorrect DMA Unmapping of SG List

2015-08-27T00:11:01+00:00

In pm8001_ccb_task_free(), the dma unmapping is done based on
ccb->n_elem value. This should be initialized to zero in the
task_abort(). Otherwise, pm8001_ccb_task_free() will try for
dma_unmap_sg() which is invalid for task abort and can lead to
kernel crash.
