* The Hardware Abstraction Layer (HW) insulates the higher-level code from the SLI-4 * message details, but the higher level code must still manage domains, ports, * IT nexuses, and IOs. The HW API is designed to help the higher level manage * these objects.

* * The HW uses function callbacks to notify the higher-level code of events * that are received from the chip. There are currently three types of * functions that may be registered: * *
  • domain – This function is called whenever a domain event is generated * within the HW. Examples include a new FCF is discovered, a connection * to a domain is disrupted, and allocation callbacks.
    • *
  • unsolicited – This function is called whenever new data is received in * the SLI-4 receive queue.
    • *
  • rnode – This function is called for remote node events, such as attach status * and allocation callbacks.
* * Upper layer functions may be registered by using the ocs_hw_callback() function. * * FC/FCoE HW *

FC/FCoE HW API

* The FC/FCoE HW component builds upon the SLI-4 component to establish a flexible * interface for creating the necessary common objects and sending I/Os. It may be used * “as is” in customer implementations or it can serve as an example of typical interactions * between a driver and the SLI-4 hardware. The broad categories of functionality include: * *
  • Setting-up and tearing-down of the HW.
    • *
  • Allocating and using the common objects (SLI Port, domain, remote node).
    • *
  • Sending and receiving I/Os.
* *

HW Setup

* To set up the HW: * *
    *
  1. Set up the HW object using ocs_hw_setup().
    * This step performs a basic configuration of the SLI-4 component and the HW to * enable querying the hardware for its capabilities. At this stage, the HW is not * capable of general operations (such as, receiving events or sending I/Os).


    2. *
  2. Configure the HW according to the driver requirements.
    * The HW provides functions to discover hardware capabilities (ocs_hw_get()), as * well as configures the amount of resources required (ocs_hw_set()). The driver * must also register callback functions (ocs_hw_callback()) to receive notification of * various asynchronous events.

    * @b Note: Once configured, the driver must initialize the HW (ocs_hw_init()). This * step creates the underlying queues, commits resources to the hardware, and * prepares the hardware for operation. While the hardware is operational, the * port is not online, and cannot send or receive data.


    3. *

    *
  3. Finally, the driver can bring the port online (ocs_hw_port_control()).
    * When the link comes up, the HW determines if a domain is present and notifies the * driver using the domain callback function. This is the starting point of the driver's * interaction with the common objects.

    * @b Note: For FCoE, there may be more than one domain available and, therefore, * more than one callback.
    4. *
* *

Allocating and Using Common Objects

* Common objects provide a mechanism through which the various OneCore Storage * driver components share and track information. These data structures are primarily * used to track SLI component information but can be extended by other components, if * needed. The main objects are: * *
  • DMA – the ocs_dma_t object describes a memory region suitable for direct * memory access (DMA) transactions.
    • *
  • SCSI domain – the ocs_domain_t object represents the SCSI domain, including * any infrastructure devices such as FC switches and FC forwarders. The domain * object contains both an FCFI and a VFI.
    • *
  • SLI Port (sport) – the ocs_sli_port_t object represents the connection between * the driver and the SCSI domain. The SLI Port object contains a VPI.
    • *
  • Remote node – the ocs_remote_node_t represents a connection between the SLI * Port and another device in the SCSI domain. The node object contains an RPI.
* * Before the driver can send I/Os, it must allocate the SCSI domain, SLI Port, and remote * node common objects and establish the connections between them. The goal is to * connect the driver to the SCSI domain to exchange I/Os with other devices. These * common object connections are shown in the following figure, FC Driver Common Objects: * FC Driver Common Objects * * The first step is to create a connection to the domain by allocating an SLI Port object. * The SLI Port object represents a particular FC ID and must be initialized with one. With * the SLI Port object, the driver can discover the available SCSI domain(s). On identifying * a domain, the driver allocates a domain object and attaches to it using the previous SLI * port object.

* * @b Note: In some cases, the driver may need to negotiate service parameters (that is, * FLOGI) with the domain before attaching.

* * Once attached to the domain, the driver can discover and attach to other devices * (remote nodes). The exact discovery method depends on the driver, but it typically * includes using a position map, querying the fabric name server, or an out-of-band * method. In most cases, it is necessary to log in with devices before performing I/Os. * Prior to sending login-related ELS commands (ocs_hw_srrs_send()), the driver must * allocate a remote node object (ocs_hw_node_alloc()). If the login negotiation is * successful, the driver must attach the nodes (ocs_hw_node_attach()) to the SLI Port * before exchanging FCP I/O.

* * @b Note: The HW manages both the well known fabric address and the name server as * nodes in the domain. Therefore, the driver must allocate node objects prior to * communicating with either of these entities. * *

Sending and Receiving I/Os

* The HW provides separate interfaces for sending BLS/ ELS/ FC-CT and FCP, but the * commands are conceptually similar. Since the commands complete asynchronously, * the caller must provide a HW I/O object that maintains the I/O state, as well as * provide a callback function. The driver may use the same callback function for all I/O * operations, but each operation must use a unique HW I/O object. In the SLI-4 * architecture, there is a direct association between the HW I/O object and the SGL used * to describe the data. Therefore, a driver typically performs the following operations: * *
  • Allocates a HW I/O object (ocs_hw_io_alloc()).
    • *
  • Formats the SGL, specifying both the HW I/O object and the SGL. * (ocs_hw_io_init_sges() and ocs_hw_io_add_sge()).
    • *
  • Sends the HW I/O (ocs_hw_io_send()).
* *

HW Tear Down

* To tear-down the HW: * *
  1. Take the port offline (ocs_hw_port_control()) to prevent receiving further * data andevents.
    2. *
  2. Destroy the HW object (ocs_hw_teardown()).
    3. *
  3. Free any memory used by the HW, such as buffers for unsolicited data.
