NAME

       daplt - Tavor uDAPL service driver

SYNOPSIS

       daplt@0:daplt

DESCRIPTION

       The daplt module is the driver component of the uDAPL service provider for Tavor which implements the provider functions of the uDAPL Spec-
       ification 1.2 described under libdat(3LIB).

       The daplt module is a child of the IB nexus driver, ib(7D), and layers on top of the Solaris kernel IB Transport Layer, ibtl(7D). The daplt
       driver uses the InfiniBand Transport Framework (IBTF). (See ibtl(7D), ibcm(7D), and ib(7D) to access privileged IB VERBS.)

       The daplt driver copies out various HCA H/W object reference handles, including working and completion queues and User Access Region regis-
       ters, to its own uDAPL service provider library for Tavor. The library can refer back to these object handles and use them  to  mmap(2)	in
       the  mapping  of these H/W queues and registers from the Tavor HCA driver, tavor(7D).  This process enables time-critical non-privileged IB
       VERBS such as send/receive work elements, RDMA read/write and memory window bind, to be invoked	in  the  userland  library  and  performed
       directly  by the firmware or hardware. As a result, OS and network stack are bypassed, achieving true zero data copy with the lowest possi-
       ble latency.

NAME

       tavor - InfiniHost MT23108/MT25208 InfiniBand (IB) Driver

SYNOPSIS

       PCI   pci15b3,5a44@pci-slot, pci15b3,5a45@pci-slot

       PCI-E pci15b3,6278@pci-e-slot, pci15b3,6279@pci-e-slot

       The  tavor  driver is an IB Architecture-compliant implementation of an HCA, which operates on the Mellanox MT23108 InfiniBand ASSP and the
       Mellanox MT25208 InfiniBand ASSP. These ASSP's support the  link and physical layers of the InfiniBand specification, while  the  ASSP  and
       the driver support the transport layer.

       The  tavor  driver  interfaces with the InfiniBand Transport Framework (IBTF) and provides an implementation of the Channel Interfaces that
       are defined by that framework. It also enables management applications and agents to access the IB fabric.

       Writing Device Drivers

       In addition to being logged, the following messages may appear on the system console.

       tavor : driver attached for maintenance mode only.

	   There was a failure in the boot process of the tavor ASSP and the only function that can be performed is to re-flash  firmware  on  the
	   ASSP.

       driver failed to attach.

	   The ASSP could not boot into either operational (HCA) mode or into maintenance mode. The device in inoperable.

       Unexpected port number in port state change event.

	   A port state change event occurred, but the port number in the message does not exist on this HCA. This message also indicates the port
	   number that was in the port state change.

       Tavor driver successfully detached.

	   The driver has been removed from the system, and the HCA is no longer available for transfer operations.

       tavor"n": port "m" up.

	   A port up asynchronous event has occured. "n" represents the instance of the Tavor device number, and "m" represents the port number on
	   the Tavor device.

       tavor"n": port "m" down.

	   A port down aynchronous event has occurred.

       Tavor: <command name> command failed.

	   A internal firmware command failed to execute.
