mod_drvattach(D3)

mod_drvattach -- install interrupts for a loadable device driver

Synopsis (Not in current DDI version)

   #include <sys/moddefs.h>
   #include <sys/ddi.h>
   
   void mod_drvattach(void *iip);

Description

mod_drvattach is called from a loadable driver's _load(D2) routine. It installs and enables interrupts for a driver being dynamically loaded into a running system.

Arguments

iip: Pointer to the driver's prefixattach_info structure.

Return values

None

Usage

The prefixattach_info structure is defined and initialized by the kernel configuration tools at the time the driver is configured into the system. The definition of the attach_info structure is not included in the DDI and can change across releases. It should be treated as a ``black box'' by the driver; none of its fields may be referenced.

Context and synchronization

User or blockable context.

Hardware applicability

All

Version applicability

ddi: 4, 5, 5mp, 6, 6mp, 7, 7mp, 7.1, 7.1mp

Differences between versions

Beginning with DDI 8, use the cm_intr_attach(D3) function rather than mod_drvattach( ).
