* [SCSI] scsi_pm: resume device if suspend failedAaron Lu2012-05-221-1/+4
| | | | | | | | | | | | | For scsi devices which use scsi bus runtime callback, runtime suspend will call scsi_dev_type_suspend, and if the drv->suspend failed, the device will still be in active state. But since scsi_device_quiesce is called, the device will not be able to respond any more commands. So add a check here to see if err occured, if so, bring the device back to normal state with scsi_device_resume.

Further details below, suffice to say if the RNC is mismanaged the silicon state machines may lock up. 2/ Refactor the initialization code to be reused for suspend/resume support 3/ Miscellaneous bug fixes to address discovery issues and hardware compatibility. RNC rework details from Jeff Skirvin: In the controller, devices as they appear on a SAS domain (or direct-attached SATA devices) are represented by memory structures known as "Remote Node Contexts" (RNCs). These structures are transferred from main memory to the controller using a set of register commands; these commands include setting up the context ("posting"), removing the context ("invalidating"), and commands to control the scheduling of commands and connections to that remote device ("suspensions" and "resumptions"). There is a similar path to control RNC scheduling from the protocol engine, which interprets the results of command and data transmission and reception. In general, the controller chooses among non-suspended RNCs to find one that has work requiring scheduling the transmission of command and data frames to a target. Likewise, when a target tries to return data back to the initiator, the state of the RNC is used by the controller to determine how to treat the incoming request. As an example, if the RNC is in the state "TX/RX Suspended", incoming SSP connection requests from the target will be rejected by the controller hardware. When an RNC is "TX Suspended", it will not be selected by the controller hardware to start outgoing command or data operations (with certain priority-based exceptions). As mentioned above, there are two sources for management of the RNC states: commands from driver software, and the result of transmission and reception conditions of commands and data signaled by the controller hardware. As an example of the latter, if an outgoing SSP command ends with a OPEN_REJECT(BAD_DESTINATION) status, the RNC state will transition to the "TX Suspended" state, and this is signaled by the controller hardware in the status to the completion of the pending command as well as signaled in a controller hardware event. Examples of the former are included in the patch changelogs. Driver software is required to suspend the RNC in a "TX/RX Suspended" condition before any outstanding commands can be terminated. Failure to guarantee this can lead to a complete hardware hang condition. Earlier versions of the driver software did not guarantee that an RNC was correctly managed before I/O termination, and so operated in an unsafe way. Further, the driver performed unnecessary contortions to preserve the remote device command state and so was more complicated than it needed to be. A simplifying driver assumption is that once an I/O has entered the error handler path without having completed in the target, the requirement on the driver is that all use of the sas_task must end. Beyond that, recovery of operation is dependent on libsas and other components to reset, rediscover and reconfigure the device before normal operation can restart. In the driver, this simplifying assumption meant that the RNC management could be reduced to entry into the suspended state, terminating the targeted I/O request, and resuming the RNC as needed for device-specific management such as an SSP Abort Task or LUN Reset Management request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | While the RNC is suspended for I/O cleanup, the remote device can be stopped and the RNC setup for destruction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RNC state machine would incorrectly transition from SCI_RNC_AWAIT_SUSPENSION directly to SCI_RNC_INVALIDATING when a destruct request was made. This would skip the increment of the suspension count and the abort of pending TCs (although the invalidating state would at least cleanup outstanding TCs). Instead, the RNC will transition to SCI_RNC_SUSPENDED and then start the destruction process.

In the abort path functions like isci_reset_device, make sure that there has not already been a detected domain failure with the device by checking IDEV_GONE, before performing any kind of hard reset, SMP phy control, or TMF operation. The check for IDEV_GONE makes sure that the device in the abort path really has control of the port with which it is associated.
