SCSI: isci: copy fis 0x34 response into proper buffer

2012-12-03T19:37:57Z

commit 49bd665c5407a453736d3232ee58f2906b42e83c upstream. SATA MICROCODE DOWNALOAD fails on isci driver. After receiving Register Device to Host (FIS 0x34) frame Initiator resets phy. In the frame handler routine response (FIS 0x34) was copied into wrong buffer and upper layer did not receive any answer which resulted in timeout and reset. This patch corrects this bug.

isci: Remove obviated host callback list.

2012-05-17T21:33:44Z

Since the callbacks to libsas now occur under scic_lock, there is no longer any reason to save the completed requests in a separate list for completion to libsas. Signed-off-by: Jeff Skirvin Signed-off-by: Dan Williams

isci: Restore the ATAPI device RNC management code.

2012-05-17T21:33:43Z

The ATAPI specific and STP general RNC suspension code had been incorrectly removed from the remote device code. Signed-off-by: Jeff Skirvin Signed-off-by: Dan Williams

isci: Add protocol indicator for TMF requests.

2012-05-17T21:33:42Z

Requests contructed as task management requests need to have the protocol indicator set so the completion decode can observe any RNC suspension conditions. Signed-off-by: Jeff Skirvin Signed-off-by: Dan Williams

isci: Save the suspension hint for upcoming suspensions.

2012-05-17T21:33:40Z

In the case of a suspend call while in SCI_RNC_POSTING or INVALIDATING states, the LLHANG detect needed to be saved so the upcoming suspension would enable it correctly. The unused suspend callback parameters were removed. Signed-off-by: Jeff Skirvin Signed-off-by: Dan Williams

isci: Fix the terminated I/O to not call sas_task_abort().

2012-05-17T21:33:40Z

This addresses a regression from the commit "isci: Redesign device suspension, abort, cleanup." in which the sas_task end condition for terminated I/Os was made to call back on sas_task_abort()". This commit will be rolled into the original. Signed-off-by: Jeff Skirvin Signed-off-by: Dan Williams

isci: Distinguish between remote device suspension cases

2012-05-17T21:33:40Z

For NCQ error conditions among others, there is no need to enable the link layer hang detect timer. Signed-off-by: Jeff Skirvin Signed-off-by: Dan Williams

isci: Remove isci_device reqs_in_process and dev_node from isci_device.

isci: Redesign device suspension, abort, cleanup.

2012-05-17T21:33:38Z

This commit changes the means by which outstanding I/Os are handled for cleanup. The likelihood is that this commit will be broken into smaller pieces, however that will be a later revision. Among the changes: - All completion structures have been removed from the tmf and abort paths. - Now using one completed I/O list, with the I/O completed in host bit being used to select error or normal callback paths.

isci: Terminate outstanding TCs on TX/RX RNC suspensions.

2012-05-17T21:33:37Z

TCs must only be terminated when RNCs are suspended. Signed-off-by: Jeff Skirvin Signed-off-by: Dan Williams
