Module Name:
SensorInfoVariable.h
Abstract:
GUID used for Sensor Info variable.
--*/
//
// Module: SensorInfoVariable.h
//
// Description: Provides structure and literal definitions for the
// Sensor Information Variable. The BIOS will provide
// this variable to runtime applications via the EFI
// GetVariable function.
//
// Notes: 1. When defining and initializing the variable within the
// BIOS, the module will define the structure using the
// typedef macros in a block. For an ATX board using a
// single Heceta 6P, which has 4 temperature sensors, 6
// voltage sensors, 4 fan speed sensors and 3 fan speed
// controllers, this block would be declared as follows:
//
// TYPEDEF_TEMP_SENSOR_SECTION(4);
// TYPEDEF_VOLT_SENSOR_SECTION(6);
// TYPEDEF_FAN_SENSOR_SECTION(4);
// TYPEDEF_FAN_CONTROLLER_SENSOR(3);
// TYPEDEF_SENSOR_INFO_VAR;
//
// 2. When crafting code to access the variable, the module
// will also need to invoke the typedef macros in a
// block but, since it cannot declare a structure for the
// overall variable (because array lengths will vary), it
// cannot use TYPEDEF_SENSOR_INFO_VAR. The block will
// typically be used as follows:
//
// TYPEDEF_TEMP_SENSOR_SECTION(1);
// TYPEDEF_VOLT_SENSOR_SECTION(1);
// TYPEDEF_FAN_SENSOR_SECTION(1);
// TYPEDEF_FAN_CONTROLLER_SENSOR(1);
//
// The structure buffer should instead be declared as a
// BYTE array. Pointers to the various sections can then
// be built using the XXXX_SECTION_LEN macros...
