SYNOPSIS
#include <sys/ddifm.h>

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_ser‐
vice_impact():
DDI_SERVICE_LOST The service provided by the device is
unavailable due to an error. The operational
state of the device will transition to
DEVI_DEVICE_DOWN.
DDI_SERVICE_DEGRADED The driver is unable to provide normal ser‐
vice, 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 avail‐
able, 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 unaf‐
fected by the error.
CONTEXT
The ddi_fm_service_impact() function can be called from user, kernel,
or high-level interrupt context.
