We can copy the data directly to and from sg for SATA PIO read operations. There is no reason to involve the hardware SGL. In the process we also need to kmap the sg because we don't know where that can come from. We also do to not call phys_to_virt(). The driver already has the information. We can just calculcate the appropriate offets. Signed-off-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

Sending aborts/resets to SAS/SATA targets in APC mode eventually causes an assert in scic_sds_apc_agent_link_up(). We need to handle the hard reset case for apc mode ports. Signed-off-by: Piotr Sawicki <piotr.sawicki@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

Update the SCI Core to comprehend the changes in the TC completion codes from A0 to B0. Specifically, there isnew R_ER code differences for command and data FISes. Changes are as follows: 1) 0x16 now additionally indicates an R_ERR received for a COMMAND FIS being sent to a SATA target. 0x16 for SSP still indicates a NAK received for a COMMAND frame. Fix is to retry TC to be compliant with SATA spec or ensure proper error handling of return value (not spec compliant I don't believe). 2) 0x1B was previously called DONE_BREAK_RCVD for STP and DONE_LL_ABORT_ERR for SSP. Now it is universally called DONE_LL_ABORT_ERR. This is purely a superficial change. 3) 0x32 is no longer a reserved code. Now it indicates DONE_CMD_SDMA_ERR for STP/SSP. There was a fatal error on the SDMA for a command IU (includes Raw frames). Consider retry, but at a minimum gracefully fail the request. 4) 0x33 is no longer a reserved code. Now it indicates DONE_CMD_LL_ABORT_ERR for SSP. There was a break receivd during transmission of a command IU. Consider retry, but at a minimum gracefully fail the request.

Use the dynamic revision detection code in scic_sds_phy_link_layer_initialization() and apply some coding style fixups (long deref chains). The compile time max link rate setting is removed in favor of honoring the user-parameter max.

This value applies regardless * of what type of device is attached or connection state.

Moved the firmware loading from per adapter to per PCI device. This should prevent firmware from being loaded twice becuase of 2 SCU controller per PCI device. We do have to do it per PCI device because request_firmware() requires a struct device passed in.

The lldd actively disallows requests in the "starting" state. Retrying or holding off commands in this state is sub-optimal: 1/ it adds another state check to the fast path 2/ retrying can cause libsas to give up However, isci's ->lldd_dev_found() routine already waits for controller start to complete before allowing further progress. Checking the "starting" state in isci_task_execute_task and the isr is redundant and misleading. Clean this up and introduce a controller-wide event queue to start reeling in "completion" proliferation in the driver. The "stopping" state cleanups are in a similar vein, rely on the the isr and other paths being precluded from occurring rather than implementing state checking logic.

This will be replaced by state machine tracepoints and should have been a part of the logger removal. Ran across scic_sds_port_decrement_request_count() which is an ugly macro which silently hides accounting errors. Turn it into a WARN_ONCE to see if it ever triggers.
