Module type A module type is distinguished by the mechanism used
to maintain the modules of that type within the kernel.
DLKM modules are classified according to a fixed
number of supported module types.
Modwrapper The additional code and data structures added to a
DLKM module in order to make it dynamic.
PCI Peripheral Component Interconnect. An
industry-standard bus used on HP-UX systems to
provide expansion I/O.
Stream A connection supported by the STREAMS facilities
between a user process and a device driver. It is a
structure made up of linked modules, each of which
processes the transmitted information and passes it to
the next module. You can use STREAMS to connect to a
wide variety of hardware and software configurations,
using building blocks, or modules, that can be stacked
together. STREAMS drivers and modules are similar in
that they both must declare the same structures and
provide the same interface. Only STREAMS drivers
manage physical hardware and must therefore be
responsible for handling interrupts if appropriate.
WSIO WSIO Workstation Input/Output. A well-defined
environment provided for driver implementation on
HP-UX workstations and servers.
