The Hot Plug Controller interface tracks system component information as well as manages the actions required for hot-plug functions. The Hot Plug Controller Interface processes Hot Plug Services Library (HPSL) requests by interfacing with the Netscape AutoConfig Subsystem.

SCO UnixWare
Supported PCI Functionality
Compaq support of PCI Hot Plug under UnixWare 7.01 provides hot-
replacement, hot-upgrade, and hot-addition for a variety of boards. You can
eliminate downtime when you replace faulty adapters, upgrade your systems,
and dynamically add new adapters.
Software Components
The primary software components for hot-plug support include:
Hot-plug user interface Admin Manager
Hot-plug Controller interface
Netscape AutoConfig Subsystem
Hot-plug system and device drivers
Device Driver Interface (DDI-8) specification
The Admin Manager is the graphical user interface for PCI Hot Plug
technology. All user commands to add, remove, or replace an adapter funnel
through the Admin Manager. The Hot Plug Admin Manager is incorporated
into SCO’s existing system-managed framework called SCO Admin.
The Hot Plug Controller interface tracks system component information as
well as manages the actions required for hot-plug functions. The Hot Plug
Controller Interface processes Hot Plug Services Library (HPSL) requests by
interfacing with the Netscape AutoConfig Subsystem. Using the existing
Compaq Support Software 2.1, auto-configuring framework hot-plug events
will be handled through the resource manager database, which has been
updated specifically in the area of dynamically loading and unloading
individual device drivers.
The device driver interface specification defines how device drivers
communicate with the UnixWare operating system and hot-plug software.
SCO’s Device Driver Interface version 8 (DDI-8) and other device driver
interfaces are enhanced to provide the functions for adding or removing driver
instances and suspending or resuming operation in conjunction with hot-plug
operations.
