Impact of error
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 transition 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.
The ddi_fm_service_impact() function can be called from
user, kernel, or high-level interrupt context.
