There is an apparent HW lockup caused when the PE is disabled while there is an outstanding TC in progress. This change puts the link into OOB to force the TC to end before the PE is disabled.

Per the SAS spec, several types of BROADCAST CHANGE primitives must cause re-discovery of the originating expander. Only the standard BROADCAST CHANGE primitive was being sent to the LIBSAS layer.

isci occasionally spews messages like: isci 0000:03:00.0: sci_phy_event_handler: PHY starting substate machine received unexpected event_code b3940000 ...which is not very helpful, since we don't know which controller, which phy, the exact state, or a decode of the event.

This field is a holdover from the OS abstraction conversion. The stable phy to port lookups are done via iphy->ownining_port under scic_lock. After this conversion to use port->lldd_port the only volatile lookup is the initial lookup in isci_port_formed(). After that point any lookup via a successfully notified domain_device is guaranteed to be valid until the domain_device is destroyed. Delete ->start_complete as it is only set once and is set as a consequence of the port going link up, by definition of getting a port formed event the port is "ready". While we are correcting port lookups also move the asd_sas_port table out from under the isci_port. This is to preclude any temptation to use container_of() to convert an asd_sas_port to an isci_port, the association is dynamic and under libsas control.

Need the following workaround in the driver for interoperability with the older Intel SSD drives and any other SATA drive that may exhibit the same behavior. This is a corner case where SCU speed is limited to either 3G or 1.5G and the drive has a period of DC idle when it switches speed during SATA speed negotiation. Workaround :change PHYTOV[31:24] from 0x36 to 0x3B.

The distinction between scic_sds_ scic_ and sci_ are no longer relevant so just unify the prefixes on sci_. The distinction between isci_ and sci_ is historically significant, and useful for comparing the old 'core' to the current Linux driver. 'sci_' represents the former core as well as the routines that are closer to the hardware and protocol than their 'isci_' brethren. sci == sas controller interface. Also unwind the 'sds1' out of the parameter structs. Reported-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NDan Williams <dan.j.williams@intel.com>
