The isci driver is for the integrated SAS controller in the Intel C600 (Patsburg) chipset. Source files in sys/dev/isci directory are FreeBSD-specific, and sys/dev/isci/scil subdirectory contains an OS-agnostic library (SCIL) published by Intel to control the SAS controller. This library is used primarily as-is in this driver, with some post-processing to better integrate into the kernel build environment. isci.4 and a README in the sys/dev/isci directory contain a few additional details. This driver is only built for amd64 and i386 targets. Sponsored by: Intel Reviewed by: scottl Approved by: scottl

|
|
* @param[in] scif_remote_device This parameter specifies the framework
|
|
* remote device with which this task request is to be associated.
|
|
* @param[in] io_tag This parameter specifies the IO tag to be associated
|
|
* with this request. If SCI_CONTROLLER_INVALID_IO_TAG is

|
|
* request will be copied into the actual controller request
|
|
* memory when the IO tag is allocated internally during the
|
|
* scif_controller_start_task() method.
|
|
* @param[in] user_task_request_object This parameter specifies the user
|
|
* task request to be utilized during task construction. This task
|
|
* pointer will become the associated object for the framework
|
|
* task request object.
|
|
* @param[in] task_request_memory This parameter specifies the memory
|
|
* to be utilized in the construction of the framework task request.
|
|
* @param[in] scif_task_request This parameter specifies the handle to be
|
|
* utilized for all further interactions with this task request
|
|
* object.

* @return Indicate if the controller successfully built the task request.
