SSA Adapter Device Driver

Purpose

To provide support for the SSA adapter.

Syntax

#include /usr/include/sys/ssa.h

#include /usr/include/sys/devinfo.h

Description

The /dev/ssan special files provide an interface that allows client application programs
to access SSA adapters and the SSA devices that are connected to those adapters.
Multiple-head device drivers and application programs can all access a particular SSA
adapter and its connected devices at the same time.

Configuring Devices

All the SSA adapters that are connected to the using system are normally configured
automatically during the system boot sequence.

PCI SSA Adapter ODM Attributes

The PCI SSA adapter has a number of object data manager (ODM) attributes that you
can display by using the lsattr command:

ucode

Holds the file name of the microcode package file that supplies the adapter
microcode that is present in an SSA adapter.

bus_io_addr

Holds the value of the bus I/O base address of the adapter registers that the
SSA adapter device driver for this adapter will use.

bus_mem_start

Holds the value of the bus-memory start address that the SSA adapter device
driver for this adapter will use.

bus_mem_start2

Holds the value of the bus-memory start address that the SSA adapter device
driver for this adapter will use.

bus_mem_start3

Holds the value of the bus-memory start address that the SSA adapter device
driver for this adapter will use.

bus_mem_start4

Holds the value of the bus-memory start address that the SSA adapter device
driver for this adapter will use.

bus_intr_level

Holds the value of the bus interrupt level that the SSA adapter device driver for
this adapter will use.
