SSA Adapter Device Driver
Purpose Toprovide support for the SSA adapter.
Syntax #include /usr/include/sys/ssa.h
#include /usr/include/sys/devinfo.h
Description The /dev/ssanspecial files provide an interface that allows client application programs
to access SSAadapters 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 SSAadapters that are connected to the using system are normally configured
automatically during the system boot sequence.
PCI SSA Adapter ODMAttributes
The PCI SSAadapter 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 SSAadapter.
bus_io_addr
Holds the value of the bus I/O base address of the adapter registers that the
SSAadapter device driver for this adapter will use.
bus_mem_start
Holds the value of the bus-memory start address that the SSAadapter device
driver for this adapter will use.
bus_mem_start2
Holds the value of the bus-memory start address that the SSAadapter device
driver for this adapter will use.
bus_mem_start3
Holds the value of the bus-memory start address that the SSAadapter device
driver for this adapter will use.
bus_mem_start4
Holds the value of the bus-memory start address that the SSAadapter device
driver for this adapter will use.
bus_intr_level
Holds the value of the bus interrupt level that the SSAadapter device driver for
this adapter will use.
