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
bus_io_addr
bus_mem_start
bus_mem_start2
bus_mem_start3
bus_mem_start4
bus_intr_level
Holds the file name of the microcode package file that supplies the adapter
microcode that is present in an SSA adapter.
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.
Holds the value of the bus-memory start address that the SSA adapter device
driver for this adapter will use.
Holds the value of the bus-memory start address that the SSA adapter device
driver for this adapter will use.
Holds the value of the bus-memory start address that the SSA adapter device
driver for this adapter will use.
Holds the value of the bus-memory start address that the SSA adapter device
driver for this adapter will use.
Holds the value of the bus interrupt level that the SSA adapter device driver for
this adapter will use.
