2011-07-03isci: Retrieve the EFI variable for OEM parameterDave Jiang2-51/+24
We can call the EFI get_variable service routine directly to retrieve the EFI variable that holds the OEM parameters table. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: removing the kmalloc in smp request constructDave Jiang1-16/+10
It doesn't look like there is any reason to do a kmalloc. We can do the byte swap in place and avoid the allocation. This allow us to remove a kmalloc and a memcpy. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Dan Williams <[email protected]>

2011-07-03isci: replace isci_timer list with proper embedded timersEdmund Nadolski4-25/+60
Rather than preallocating a list of timers and doling them out at runtime, embed a struct timerlist in each object that needs one. A struct sci_timer interface is introduced to manage the timer cancellation semantics which currently need to guarantee the timer is cancelled while holding spin_lock(ihost->scic_lock). Since the timeout functions also need to acquire the lock it currently prevents the driver from using del_timer_sync() for runtime cancellations. del_timer_sync() is used however before the objects go out of scope.

2011-07-03isci: add some type safety to the state machine interfaceDan Williams8-194/+148
Now that any given object type only has one state_machine we can use container_of() to get back to the given state machine owner. Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>

remove the handler from the port state handler table and implement the logic directly in scic_sds_port_start(). Signed-off-by: Piotr Sawicki <[email protected]> [remove a level of indirection] Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: merge port ready substates into primary state machinePiotr Sawicki2-256/+210
This conversion was complicated by the fact that the ready state exit routine took unconditional action beyond just stopping the substate machine (like in previous conversions). In order to ensure identical behaviour every state transition needs to be instrumented to catch ready-->!ready transitions and execute scic_sds_port_invalidate_dummy_remote_node() Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Piotr Sawicki <[email protected]> [fix ready state exit handling] Signed-off-by: Dan Williams <[email protected]>

Name the table fields for consistancy and clarity. Signed-off-by: Piotr Sawicki <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: clarify phy to port lookupsDan Williams5-12/+11
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 <[email protected]>
2011-07-03isci: unify phy consume_power handlersDan Williams2-527/+83
Unify the implementations in scic_sds_phy_consume_power_handler(), and kill the state handler plus infrastructure. Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>

2011-07-03isci: merge phy substatesAdam Gruchala3-299/+276
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 <[email protected]> Signed-off-by: Adam Gruchala <[email protected]> [fixed construction, starting_state_enter, and starting check] Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: remove the completion and event state handlersDan Williams2-469/+82
With these handlers gone the rest of the state handler infrastructure is removed. Added some WARN_ONCEs where previously we would cause NULL pointer dereferences or silently run handlers from a previous state. Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: remove request task context completion state handlerDan Williams2-337/+197
Unlike the other conversions this only updates scic_sds_io_request_tc_completion() to call the old state handlers directly (with less verbose names). This was done for future patch readability, the implementations have only minor differences for different completion codes. Without a reference to the function name it would be difficult to dicern which state is being updated. Considered changing the order to look up the completion code before the state but that was not a clean conversion either. Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: unify request frame handlersDan Williams3-607/+422
Unify the implementation in scic_sds_io_request_frame_handler and kill the state handler. Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>

2011-07-03isci: merge stp request substates into primary state machineDan Williams5-1927/+1571
Remove usage of the request substate machine for stp requests, and kill the request substate infrastructure. Similar to the previous conversions this adds the substates to the primary state machine and arranges for the 'started' state to transition to the proper stp substate. Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: merge smp request substates into primary state machineDan Williams5-593/+436
Remove usage of the request substate machine for smp requests identified by: task->task_proto == SAS_PROTOCOL_SMP While merging over the smp_request infrastructure noticed that all the assign buffer implementations are now equal, so moved it to scic_sds_general_request_construct. Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: merge ssp task management substates into primary state machineDan Williams4-286/+178
Remove usage of the request substate machine for ssp task management requests identified by: ireq->ttype == tmf_task && dev->dev_type == SAS_END_DEV; The only routine that checks the base 'started' state is scic_sds_io_request_tc_completion which calls the substate machine handler if we are not in the 'started' state or we are 'started' and no substate machine is defined. This routine requires no conversion because we have transitioned out of 'started' and the substate routine will be called naturally as a result. There are also no side effects of this conversion on exiting the 'started', state because it only stops the substate machine, which is no longer relevant for this transaction type.

2011-07-03isci: unify constantsDan Williams38-962/+497
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 <[email protected]>
2011-07-03isci: unify request data structuresDan Williams15-257/+128
Make scic_sds_request a proper member of isci_request. Also let's us get rid of the dma pool object size tracking since we now know that all requests are sizeof(isci_request). While cleaning up the construct routine incidentally replaced SCI_FIELD_OFFSET with offsetof. Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>
