NAME
       ddi_fm_service_impact - report the impact of an error

SYNOPSIS

       void ddi_fm_service_impact(dev_info_t *dip, int *impact);

       Solaris DDI specific (Solaris DDI)

PARAMETERS
       dip	 Pointer to the dev_info structure

       impact	 Impact of error

DESCRIPTION
       The following service impact values are accepted by ddi_fm_service_impact():

       DDI_SERVICE_LOST 	 The service provided by the device is unavailable due to an error. The operational state of the device will tran-
				 sition to DEVI_DEVICE_DOWN.

       DDI_SERVICE_DEGRADED	 The driver is unable to provide normal service, but it can provide a partial or degraded level  of  service.  The
				 driver  might	have to make repeated attempts to perform an operation before it succeeds, or it may be running at
				 less than its configured speed. A driver may use this value to indicate that an alternative device should be used
				 if  available,  but  that it can continue operation if no alternative exists. The operational state of the device
				 will transition to DEVI_DEVICE_DEGRADED.

       DDI_SERVICE_RESTORED	 The service provided by the device has been restored. The operational state of the device will transition to  its
				 pre-error condition state and DEVI_DEVICE_DOWN or DEVI_DEVICE_DEGRADED is removed.

       DDI_SERVICE_UNAFFECTED	 The service provided by the device was unaffected by the error.

CONTEXT
       The ddi_fm_service_impact() function can be called from user, kernel, or high-level interrupt context.
