OPAL Sensor Groups¶

See ibm,opal/sensor-groups for device tree layout.

OPAL_SENSOR_GROUP_ENABLE¶

#define OPAL_SENSOR_GROUP_ENABLE             163

int opal_sensor_group_enable(u32 group_hndl, int token, bool enable);

OPAL call to enable/disable the sensor group using a handle to identify the type of sensor group provided in the device tree.

For example this call is used to disable/enable copying of sensor group by OCC to main memory.

The call can be asynchronus, where the token parameter is used to wait for the completion.

OPAL_SUCCESS: Success
OPAL_UNSUPPORTED: No support to enable/disable the sensor group
OPAL_HARDWARE: Unable to procced due to the current hardware state
OPAL_PERMISSION: Hardware cannot take the request
OPAL_ASYNC_COMPLETION: Request was sent and an async completion message will be sent with token and status of the request.
OPAL_BUSY: Previous request in progress
OPAL_INTERNAL_ERROR: Error in request response
OPAL_TIMEOUT: Timeout in request completion

int opal_sensor_group_clear(u32 group_hndl, int token);

#define OPAL_SENSOR_GROUP_CLEAR                      156

OPAL call to clear the sensor groups data using a handle to identify the type of sensor group which is exported via DT.

The call can be asynchronus, where the token parameter is used to wait for the completion.

OPAL_SUCCESS: Success
OPAL_UNSUPPORTED: No support for clearing the sensor group
OPAL_HARDWARE: Unable to procced due to the current hardware state
OPAL_PERMISSION: Hardware cannot take the request
OPAL_ASYNC_COMPLETION: Request was sent and an async completion message will be sent with token and status of the request.
OPAL_BUSY: Previous request in progress
OPAL_INTERNAL_ERROR: Error in request response
OPAL_TIMEOUT: Timeout in request completion
