isci: Remove obviated host callback list.

2012-05-17T21:33:44+00:00

Since the callbacks to libsas now occur under scic_lock, there is no
longer any reason to save the completed requests in a separate list
for completion to libsas.

isci: Manage tag releases differently when aborting tasks.

2012-05-17T21:33:41+00:00

When an individual request is being terminated, the request's tag
is managed in the terminate function.

isci: Redesign device suspension, abort, cleanup.

2012-05-17T21:33:38+00:00

This commit changes the means by which outstanding I/Os are handled
for cleanup.
The likelihood is that this commit will be broken into smaller pieces,
however that will be a later revision.  Among the changes:

- All completion structures have been removed from the tmf and
abort paths.
- Now using one completed I/O list, with the I/O completed in host bit being
used to select error or normal callback paths.

isci: Terminate outstanding TCs on TX/RX RNC suspensions.

2012-05-17T21:33:37+00:00

TCs must only be terminated when RNCs are suspended.

isci: Handle all suspending TC completions

2012-05-17T21:33:37+00:00

Add comprehensive decode for all TC completions that generate RNC
suspensions.

Note that this commit also removes unconditional resumptions of ATAPI
devices when in the SCI_STP_DEV_ATAPI_ERROR state, and STP devices
when in the SCI_STP_DEV_IDLE state. This is because the SCI_STP_DEV_IDLE
and SCI_STP_DEV_ATAPI state entry functions manage the RNC resumption.

isci: kill sci_phy_protocol and sci_request_protocol

2012-05-17T19:27:11+00:00

Holdovers from the initial driver cleanup, replace with enum sas_protocol.

[SCSI] isci: debug, provide state-enum-to-string conversions

2012-02-29T22:23:15+00:00

Debugging the driver requires tracing the state transtions and tracing
state names is less work than decoding numbers.

[SCSI] isci: stop interpreting ->lldd_lu_reset() as an ata soft-reset

2012-02-29T21:13:40+00:00

Driving resets from libsas-eh is pre-mature as libata will make a
decision about performing a softreset.  Currently libata determines
whether to perform a softreset based on ata_eh_followup_srst_needed(),
and none of those conditions apply to isci.

Remove the srst implementation and translate ->lldd_lu_reset() for ata
devices as a request to drive a reset via libata-eh.

[SCSI] isci: Remove redundant isci_request.ttype field.

Use the existing IREQ_TMF flag as a request type indicator.
