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: Fixup SSP command IU and task IUDave Jiang5-285/+74

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]>

2011-07-03isci: Convert ATA defines to Linux native definesDave Jiang13-1180/+280
* 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.

2011-07-03isci: fix remote_device start_io regressionsDan Williams1-6/+5
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. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: kill scic_remote_device_get_connection_rateDan Williams5-32/+3
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.

2011-07-03isci: Remove excessive log noise with expander hot-unplugDave Jiang1-7/+8

2011-07-03isci: allow fallback to option-rom if efi variable retrieval failsDan Williams1-2/+3

2011-07-03isci: remove scic_sds_remote_device_get_port_indexDan Williams2-15/+5

2011-07-03isci: remove usage of sci_sas_address in scic_sds_remote_deviceDan Williams3-11/+5
The sas address can be retrieved from the domain device and then converted to the always little-endian format in the remote node context. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: kill smp_discover_responseDan Williams4-337/+23
An lldd need never look at the contents of an smp_discover_response frame. Kill the remaining locations where isci is looking at it: 1/ covering for expanders that do not set the stp_attached bit (already handled by sas_ex_discover_end_dev) 2/ an overkill method to notifiy the rest of the driver about remote_device sas addresses Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: kill smp_discover_response_protocols in favor of domain_device.dev_typeDan Williams9-178/+118
This is step 1 of removing the contortions to: 1/ unparse expander phy data into a smp discover frame 2/ open-code-parse the smp discover fram into a domain_device.dev_type equivalent libsas has already spent cycles determining the dev_type, so now that scic_sds_remote_device is unified with isci_remote_device we can directly reference dev_type. This might also change multi-level expander detection as we previously only looked at dev_type == EDGE_DEV and we did not consider the FANOUT_DEV case. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: cleanup remote device construction and commentsDan Williams1-59/+42
The construction routines scic_remote_device_[de]a_construct both reference the need to call scic_remote_device_construct first. Delete that comment and just have them call it explicitly, also: * move the comments from header to source * delete dead references to scic_[de]a_remote_device_add_phy Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: move remote_device handling out of the coreDan Williams30-2758/+2325
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 <[email protected]>
2011-07-03isci: unify remote_device data structuresDan Williams9-75/+28
Make it explicit that isci_remote_device and scic_sds_remote_device are one in the same object. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: remove rnc->device back pointerDan Williams4-90/+65
Now that they are one in the same object remove the back pointer reference in favor of container_of. Signed-off-by: Dan Williams <[email protected]>
2011-07-03isci: make a remote_node_context a proper member of a remote_deviceDan Williams6-55/+45
A rnc object has the same lifetime as its associated remote_device. It might get re-initialized, but a remote device always has an rnc member. Preparation for unifying scic_sds_remote_device and isci_remote_device Signed-off-by: Dan Williams <[email protected]>
