Developer Enhancements

The following developer tool enhancements have been added to the Solaris 10 1/06 release. To view developer tools that are new in the previous Solaris 10 3/05 release, see Developer Tool Enhancements.

mediaLib 2.3

This feature is new in the Solaris Express 10/05 release and in the Solaris 10 1/06 release.

mediaLib is a low-level application library for building portable, high-performance, multimedia applications. These applications are useful in the telco, bioinformatics, and database fields. mediaLib 2.3 introduces a multithreaded (MT) library for better performance on multiprocessor systems. mediaLib 2.3 also introduces 340 new functions.

For further information, see the libmlib(3LIB) and libmlib_mt(3LIB) man pages. See also http://www.sun.com/processors/vis/mlib.html.

Advanced DDI Interrupts

This enhancement is new in the Solaris Express 6/05 release and the Solaris 10 1/06 release.

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

The framework includes the following new interfaces:

• ddi_intr_add_handler

• ddi_intr_add_softint

• ddi_intr_alloc

• ddi_intr_block_disable

• ddi_intr_block_enable

• ddi_intr_clr_mask

• ddi_intr_disable

• ddi_intr_dup_handler

• ddi_intr_enable

• ddi_intr_free

• ddi_intr_get_cap

• ddi_intr_get_hilevel_pri

• ddi_intr_get_navail

• ddi_intr_get_nintrs

• ddi_intr_get_pending

• ddi_intr_get_pri

• ddi_intr_get_softint_pri

• ddi_intr_get_supported_types

• ddi_intr_remove_handler

• ddi_intr_remove_softint

• ddi_intr_set_cap

• ddi_intr_set_mask

• ddi_intr_set_pri

• ddi_intr_set_softint_pri

• ddi_intr_trigger_softint

To take advantage of the features of the new framework, developers need to use the new interfaces. Avoid using the following interfaces, which are retained for compatibility only:

• ddi_add_intr

• ddi_add_softintr

• ddi_dev_nintrs

• ddi_get_iblock_cookie

• ddi_get_soft_iblock_cooki

• ddi_iblock_cookie

• ddi_idevice_cookie

• ddi_intr_hilevel

• ddi_remove_intr

• ddi_remove_softintr

• ddi_trigger_softintr

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