2011-07-03isci: merge sata.[ch] into request.cDan Williams
Undo some needless separation. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: additional state machine cleanupEdmund Nadolski
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: remove isci_timer interfaceEdmund Nadolski
Delete code which is no longer used. Signed-off-by: Edmund Nadolski <edmund.nadolski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: merge stp request substates into primary state machineDan Williams
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.

2011-07-03isci: merge smp request substates into primary state machineDan Williams
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 <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: merge ssp task management substates into primary state machineDan Williams
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: uplevel port infrastructureDan Williams
* Move port configuration agent implementation * Merge core/scic_sds_port.[ch] into port.[ch] Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: uplevel phy infrastructureDan Williams
Merge core/scic_sds_phy.[ch] into phy.[ch] Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: uplevel request infrastructureDan Williams
* Consolidate tiny header files * Move files out of core/ (drop core/scic_sds_ prefix) * Merge core/scic_sds_request.[ch] into request.[ch] * Cleanup request.c namespace (clean forward declarations and global namespace pollution) Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: uplevel state machineDan Williams
unify core/sci_base_state.h and core/sci_base_state_machine.[ch] into state_machine.[ch] Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: uplevel register hardware data structures and unsolicited frame handlingDan Williams

2011-07-03isci: move core/controller to hostDan Williams
Now that the data structures are unified unify the implementation in host.[ch] and cleanup namespace pollution. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

2011-07-03isci: merge remote_device substates into a single state machineDan Williams
A substate is just a state, so uplevel the smp and stp device substates. Three tricks at work here: 1/ scic_sds_remote_device_ready_state_enter: needs to know the the device type so it can immediately transition to a stp or smp ready substate. 2/ scic_sds_remote_device_ready_state_exit: needs to know the device type. In the ssp case the device is no longer ready, in the stp, and smp case we have simply exited to a ready "substate". 3/ scic_sds_remote_device_resume_complete_handler: The one location where we directly check the current state against SCI_BASE_REMOTE_DEVICE_STATE_READY needed to comprehend the possible ready substates.

2011-07-03isci: removing non-working ATAPI codeDave Jiang
Removing not used / bit-rotten ATAPI code. This needs to go back and debugged at a later date. Signed-off-by: Dave Jiang <dave.jiang@intel.com> [reflow against devel, delete dead sati headers] Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: move remote_device handling out of the coreDan Williams
Now that the core/lldd remote_device data structures are nominally unified merge the corresponding sources into the top-level directory. Also move the remote_node_context infrastructure which has no analog at the lldd level. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: simplify dma coherent allocationChristoph Hellwig
Remove the insane infrastructure for preallocating coheren DMA regions, and just allocate the memory where needed. This also gets rid of the aligment adjustments given that Documentation/DMA-API-HOWTO.txt sais: "The cpu return address and the DMA bus master address are both guaranteed to be aligned to the smallest PAGE_SIZE order which is greater than or equal to the requested size. This invariant exists (for example) to guarantee that if you allocate a chunk which is smaller than or equal to 64 kilobytes, the extent of the buffer you receive will not cross a 64K boundary." Signed-off-by: Christoph Hellwig <hch@lst.de> [djbw: moved allocation from start to init, re-add memset] Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: Remove event_* calls as they are just wrappersDave Jiang
Removed isci_event_* calls and call those functions directly. Reported-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: Add support for probing OROM for OEM paramsDan Williams
We need to scan the OROM for signature and grab the OEM parameters. We also need to do the same for EFI. If all fails then we resort to user binary blob, and if that fails then we go to the defaults. Share the format with the create_fw utility so that all possible sources of the parameters are in-sync.
