sdi_intr_attach(D3sdi)

sdi_intr_attach -- attach interrupts for a HBA device

Synopsis

   #include <sys/sdi.h>

   void sdi_intr_attach(HBA_IDATA_STRUCT *idata, int cntls,
   	void (*intr)(), int devflag);

Description

sdi_intr_attach attaches the interrupt intr for each hardware instance whose idata structure is marked active (for example, the active field of the idata structure is non-zero).

Arguments

idata: Pointer to array of idata structures (one for each controller controlled by the calling HBA driver)
cntls: Number of controllers. This should represent the size of the idata structure array.
intr: Pointer to interrupt routine to be attached.
devflag: The device driver's HBA device flag.

Return values

None

Usage

sdi_intr_attach is called by an HBA driver to attach interrupts (usually during initialization). The interrupts can be detached by calling the sdi_acfree(D3sdi) routine.

Context and synchronization

Blockable context.

Driver-defined basic locks and read/write locks cannot be held across calls to this function. Driver-defined sleep locks can be held across calls to this function.

Applicable hardware

x86/Pentium compatible architectures

Version applicability

sdi: 2, 3, 4 HBA drivers that use DDI versions prior to version 8.

Differences between versions

SDI version 4 and later drivers use the standard DDI 8 interfaces to attach interrupts for each hardware instance.
