2011-07-03isci: kill 'get/set' macrosDan Williams1-17/+0
Most of these simple dereference macros are longer than their open coded equivalent. Deleting enum sci_controller_mode is thrown in for good measure. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: retire scic_sds_ and scic_ prefixesDan Williams1-35/+35
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: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: unify isci_port and scic_sds_portDan Williams1-5/+5
Remove the distinction between these two implementations and unify on isci_port (local instances named iport). The duplicate '->owning_port' and '->isci_port' in both isci_phy and isci_remote_device will be fixed in a later patch... this is just the straightforward rename/unification. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: unify isci_phy and scic_sds_phyDan Williams1-87/+25
They are one in the same object so remove the distinction. The near duplicate fields (owning_port, and isci_port) will be cleaned up after the scic_sds_port isci_port unification. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: additional state machine cleanupEdmund Nadolski1-1/+1
Additional state machine cleanups: o Remove static functions sci_state_machine_exit_state() and sci_state_machine_enter_state() o Combines sci_base_state_machine_construct() and sci_base_state_machine_start() into a single function, sci_init_sm() o Remove sci_base_state_machine_stop() which is unused. o Kill state_machine.[ch] Signed-off-by: Edmund Nadolski <edmund.nadolski@intel.com> [fixed too large to inline functions] Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: state machine cleanupEdmund Nadolski1-17/+17
This cleans up several areas of the state machine mechanism: o Rename sci_base_state_machine_change_state to sci_change_state o Remove sci_base_state_machine_get_state function o Rename 'state_machine' struct member to 'sm' in client structs o Shorten the name of request states o Shorten state machine state names as follows: SCI_BASE_CONTROLLER_STATE_xxx to SCIC_xxx SCI_BASE_PHY_STATE_xxx to SCI_PHY_xxx SCIC_SDS_PHY_STARTING_SUBSTATE_xxx to SCI_PHY_SUB_xxx SCI_BASE_PORT_STATE_xxx to SCI_PORT_xxx and SCIC_SDS_PORT_READY_SUBSTATE_xxx to SCI_PORT_SUB_xxx SCI_BASE_REMOTE_DEVICE_STATE_xxx to SCI_DEV_xxx SCIC_SDS_STP_REMOTE_DEVICE_READY_SUBSTATE_xxx to SCI_STP_DEV_xxx SCIC_SDS_SMP_REMOTE_DEVICE_READY_SUBSTATE_xxx to SCI_SMP_DEV_xxx SCIC_SDS_REMOTE_NODE_CONTEXT_xxx_STATE to SCI_RNC_xxx Signed-off-by: Edmund Nadolski <edmund.nadolski@intel.com> Signed-off-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: convert phy sata_timeout_timer to sci_timerEdmund Nadolski1-4/+4
Convert the sata_timeout_timer in the scic_sds_phy struct to use a struct sci_timer Signed-off-by: Edmund Nadolski <edmund.nadolski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: clarify phy to port lookupsDan Williams1-2/+1
While cleaning up the driver it is very tempting to convert scic_sds_get_* macros to their open coded equivalent. They are all just pointer dereferences *except* scic_sds_phy_get_port() which returns NULL if the phy is assigned to the dummy port. Clarify this by renaming it to phy_get_non_dummy_port(). Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: unify phy consume_power handlersDan Williams1-36/+0
Unify the implementations in scic_sds_phy_consume_power_handler(), and kill the state handler plus infrastructure. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

2011-07-03isci: merge phy substatesAdam Gruchala1-31/+20
Merged states and substates into one state machine, as we always unconditionally transitioned to the substate machine it was straightforward to enter that substate from the starting state. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Adam Gruchala <adam.gruchala@intel.com> [fixed construction, starting_state_enter, and starting check] Signed-off-by: Dan Williams <dan.j.williams@intel.com>

2011-07-03isci: unify constantsDan Williams1-4/+1
cross driver constants are spread out over multiple header files, consolidate them into isci.h, and push some includes out to the source files that need them. TODO: remove SCI_MODE_SIZE infrastructure. TODO: task.h is full of inlines that are too large Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: unify phy data structuresDan Williams1-22/+19
Make scic_sds_phy a member of isci_phy and merge their lifetimes which means removing the phy table from scic_sds_controller in favor of the one at that isci_host level. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: unify isci_host data structuresArtur Wojcik1-2/+0
