Advanced DDI Interrupt Framework

This device management enhancement is new in the Solaris Express 12/05 release.

The Solaris OS provides a new DDI interrupt framework for registering interrupts and for deregistering interrupts. Support for Message Signaled Interrupts (MSIs) is also provided. Management interfaces enable you to manipulate priorities and capabilities, to perform interrupt masking, and to obtain pending information.

For a list of the new interfaces, see Interrupt Functions in Writing Device Drivers. For a list of interrupt functions that are obsolete and should not be used, see the “B-3 Deprecated Interrupt Functions” table within this section.

For more information, see Chapter 8, Interrupt Handlers, in Writing Device Drivers. See also the individual man pages for the interfaces. All man pages for these interfaces are in the 9F man page section.
