halt(D2mdi)

halt -- shut down the driver when the system shuts down

Synopsis

See halt(D2) for syntax, context, and general usage information about this entry point routine in DDI drivers.

See halt(D2oddi) for syntax, context, and general usage information about this entry point routine in ODDI drivers.

Usage

All MDI drivers that use DDI 7 must include the halt( ) entry point routine to disable all interrupts on all devices. This is especially critical for PCI devices and devices that may share interrupts with other devices.

Applicable hardware

All

Version applicability

mdi: 1, 2, 2.1 running with ddi: 7, 7mp.

Differences between versions

MDI drivers running with DDI 8 should implement this functionality with the CFG_SUSPEND subfunction of the config(D2mdi) entry point routine.
