_load(D2sdi)

_load -- prepare to load a driver

Synopsis

See the _load(D2) manual page for Synopsis, Arguments, Context, and Version Applicability information.

Usage

For many HBA drivers, the _load( ) entry point routine merely calls the drv_attach(D3) function. Additional initialization is coded in the CFG_ADD subfunction to the config(D2sdi) entry point routine, which executes for each configured device.

Applicable hardware

All

Differences between versions

For DDI versions prior to version 8, _load( ) is called only for DLKMs, not for statically-linked drivers. For DDI 8 and later drivers, the _load( ) entry point is called to initialize statically-linked drivers as well as DLKMs.

For SDI drivers that use DDI versions prior to version 8, the HBA driver's _load( ) routine should call the sdi_intr_attach(D3sdi) function (or, for earlier SDI drivers that do not support autoconfiguration, the mod_drvattach(D3) function) to install the interrupt vectors, with an argument of the address of xxx_attach_info. The HBA driver can then enable HBA interrupts and register the HBA with SDI.
