The following is a ‘C’-style definition of the ASF_ALERTDATA structure.
struct ASF_ALERTDATA {
BYTE DeviceAddress;
BYTE Command;
BYTE DataMask;
BYTE CompareValue;
BYTE EventSensorType;
BYTE EventType;
BYTE EventOffset;
BYTE EventSourceType;
BYTE EventSeverity;
BYTE SensorNumber;
BYTE Entity;
BYTE EntityInstance;
};
4.1.2.4 ASF_RCTL
Devices might be used in a system to provide ASF-compatible remote-control system actions.
This (optional) information provides an alert-sending device’s OS-present configuration software
with the information needed to command those devices to perform remote-control functions over
the SMBus. This structure is associated with an ASF Information Record Header of the following
format:
Type = 02h or 82h
Reserved = 00h
Length = 4 + 4 + n*m for ASF Version 1.0. Note that this length might increase for future
versions of this specification
7
The alert-sending device sets these values into the PET frame it transmits if the associated
alerting condition is active.
