2011-07-03isci: move task context alignment from run-time to compile timeDan Williams4-113/+13
Remove usage of PTR_ALIGN by arranging for the task context to be aligned by the compiler. Another step towards unifying isci_request and scic_sds_request. Once this is complete the task context in the request can likely be removed in favor of building the task directly to tc memory (see: scic_sds_controller_copy_task_context). It's not clear why this needs to be cacheline aligned if we just end up copying before submission... Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: make sgl explicit/aligned request object memberDan Williams7-64/+19
Towards unifying request objects we need all members to be defined in the object and not carved out of anonymous buffer space. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: move stp request info to scic_sds_requestDan Williams5-435/+313
In preparation for unifying allocation of all request information make stp data available in all requests. Incidentally collapse indentation. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: unify port data structuresDan Williams12-113/+67
Make scic_sds_port a member of isci_port and merge their lifetimes which means removing the port table from scic_sds_controller in favor of the one at the isci_host level. Merge ihost->sas_ports into ihost->ports. _ Reported-by: Christoph Hellwig <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: unify phy data structuresDan Williams10-313/+187
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 <[email protected]> Signed-off-by: Dan Williams <[email protected]>

2011-07-03isci: kill scic_controller_get_port_handle functionEdmund Nadolski4-78/+25
This function is just overkill and its usage is inconsistent. Replace with inlined code. Signed-off-by: Edmund Nadolski <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: Removing unnecessary functions in request.cDave Jiang3-71/+12

2011-07-03isci: unify isci_host data structuresArtur Wojcik18-163/+83
Make it explicit that isci_host and scic_sds_controller are one in the same object. Signed-off-by: Artur Wojcik <[email protected]> [removed ->ihost back pointer] Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: implement I_T_nexus_resetDan Williams3-64/+76
This is a requirement for 2.6.39's new libata eh. Still some questions about lldd_dev_gone racing against dev->lldd_dev lookups, but we are at least no more broken than mvsas in this regard. We also short-circuit I_T_nexus_reset invocations from the device discovery path (IDEV_EH similar to MVS_DEV_EH) to filter out the resulting domain rediscoveries triggered by the reset. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: fix ata lockingDan Williams1-13/+13
Upstream commit a29b5dad "libata: fix locking for sas paths" switched libsas ata locking to the ata_host lock. We need to do the same when returning ata tasks from the execute path. Signed-off-by: Dan Williams <[email protected]>

2011-07-03isci: Using Linux SSP frame headerDave Jiang5-68/+22
Removing of struct sci_ssp_frame_header and migrate to struct ssp_frame_hdr. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: Remove SCIC_SWAP_DWORD()Dave Jiang5-91/+60
Use Linux native swab32() call instead of SCIC_SWAP_DWORD(). We need to swab() because the hardware munges the data into a "big-endian dword" stream which is byte-swapped from the sas definition regardless of host endian.

2011-07-03isci: fixup SAS iaf protocols data structureDave Jiang7-138/+59
Moved the actual data structure that's read from the phy register to phy header. Removed the parsing of identify address frame protocol bits as that seemed not necessary and we can use existing information.

2011-07-03isci: remove redundant copies of IAFDave Jiang5-136/+11
We need to remove the extra copies of identify address frame that's being kept around. We only need the one copy that libsas is using. Signed-off-by: Dave Jiang <[email protected]> [further cleanups] Signed-off-by: Dan Williams <[email protected]>

2011-07-03isci: Fixup of smp requestDave Jiang5-260/+196
The struct smp_request data structure has be fixed up for Linux consumption. This probably should go to scsi/sas.h eventually. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: Convert of sci_ssp_response_iu to ssp_response_iuDave Jiang6-252/+141
Converting to Linux native format. However the isci driver does a lot of the calculation based on the max size of this data structure and the Linux data structure only has a pointer to the response data. Thus the sizeof(struct ssp_response_iu) will be incorrect and we need to define the max size. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Dan Williams <[email protected]>

2011-07-03isci: renaming sas_capabilities to scic_phy_capDave Jiang3-55/+50
This seems to be a data structure that represents the phy capabilities register from the hardware and has nothing to do with SAS data structs. Moving and fixup Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Dan Williams <[email protected]>

* Removing all intel_sata and intel_ata defines * Removing the usage of SAT_PROTOCOL_*. We can get everything from sas_task * Moved SATA FIS types to local sas.h. These defines will have to go into include/scsi/sas.h eventually. * Added offsets for SATA FIS header in order to grab the values Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Dan Williams <[email protected]>

While reducing indentation commits 7ab92c9e "isci: make a remote_node_context a proper member of a remote_device", 0879e6a6 "isci: merge remote_device substates into a single state machine" broke handling of situations where i/o's successfully started at the port level need to terminated when the remote_node declines to start the i/o.

A function call to dereference a pointer is a tad much. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: merge remote_device substates into a single state machineDan Williams5-1396/+800
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.
