The data hub protocol is used both by agents wishing to log data and those wishing to be made aware of all information that has been logged. This protocol may only be called <= TPL_NOTIFY.

| typedef EFI_STATUS(EFIAPI * EFI_DATA_HUB_GET_NEXT_RECORD) (IN EFI_DATA_HUB_PROTOCOL *This, IN OUT UINT64 *MonotonicCount, IN EFI_EVENT *FilterDriver OPTIONAL, OUT EFI_DATA_RECORD_HEADER **Record) |
Allows the system data log to be searched.
| This | The EFI_DATA_HUB_PROTOCOL instance. |
| MonotonicCount | On input, it specifies the Record to return. An input of zero means to return the first record, as does an input of one. |
| FilterDriver | If FilterDriver is not passed in a MonotonicCount of zero, it means to return the first data record. If FilterDriver is passed in, then a MonotonicCount of zero means to return the first data not yet read by FilterDriver. |
| Record | Returns a dynamically allocated memory buffer with a data record that matches MonotonicCount. |
| EFI_SUCCESS | Data was returned in Record. |
| EFI_INVALID_PARAMETER | FilterDriver was passed in but does not exist. |
| EFI_NOT_FOUND | MonotonicCount does not match any data record in the system. If a MonotonicCount of zero was passed in, then no data records exist in the system. |
| EFI_OUT_OF_RESOURCES | Record was not returned due to lack of system resources. |
| typedef EFI_STATUS(EFIAPI * EFI_DATA_HUB_LOG_DATA) (IN EFI_DATA_HUB_PROTOCOL *This, IN EFI_GUID *DataRecordGuid, IN EFI_GUID *ProducerName, IN UINT64 DataRecordClass, IN VOID *RawData, IN UINT32 RawDataSize) |
Logs a data record to the system event log.
| This | The EFI_DATA_HUB_PROTOCOL instance. |
| DataRecordGuid | A GUID that indicates the format of the data passed into RawData. |
| ProducerName | A GUID that indicates the identity of the caller to this API. |
| DataRecordClass | This class indicates the generic type of the data record. |
| RawData | The DataRecordGuid-defined data to be logged. |
| RawDataSize | The size in bytes of RawData. |
| EFI_SUCCESS | Data was logged. |
| EFI_OUT_OF_RESOURCES | Data was not logged due to lack of system resources. |
| typedef struct _EFI_DATA_HUB_PROTOCOL EFI_DATA_HUB_PROTOCOL |
| typedef EFI_STATUS(EFIAPI * EFI_DATA_HUB_REGISTER_FILTER_DRIVER) (IN EFI_DATA_HUB_PROTOCOL *This, IN EFI_EVENT FilterEvent, IN EFI_TPL FilterTpl, IN UINT64 FilterClass, IN EFI_GUID *FilterDataRecordGuid OPTIONAL) |
Registers an event to be signaled every time a data record is logged in the system.
| This | The EFI_DATA_HUB_PROTOCOL instance. |
| FilterEvent | The EFI_EVENT to signal whenever data that matches FilterClass is logged in the system. |
| FilterTpl | The maximum EFI_TPL at which FilterEvent can be signaled. It is strongly recommended that you use the lowest EFI_TPL possible. |
| FilterClass | FilterEvent will be signaled whenever a bit in EFI_DATA_RECORD_HEADER.DataRecordClass is also set in FilterClass. If FilterClass is zero, no class-based filtering will be performed. |
| FilterDataRecordGuid | FilterEvent will be signaled whenever FilterDataRecordGuid matches EFI_DATA_RECORD_HEADER.DataRecordGuid. If FilterDataRecordGuid is NULL, then no GUID-based filtering will be performed. |
| EFI_SUCCESS | The filter driver event was registered |
| EFI_ALREADY_STARTED | FilterEvent was previously registered and cannot be registered again. |
| EFI_OUT_OF_RESOURCES | The filter driver event was not registered due to lack of system resources. |
| typedef EFI_STATUS(EFIAPI * EFI_DATA_HUB_UNREGISTER_FILTER_DRIVER) (IN EFI_DATA_HUB_PROTOCOL *This, IN EFI_EVENT FilterEvent) |
Stops a filter driver from being notified when data records are logged.
| This | The EFI_DATA_HUB_PROTOCOL instance. |
| FilterEvent | The EFI_EVENT to remove from the list of events to be signaled every time errors are logged. |
| EFI_SUCCESS | The filter driver represented by FilterEvent was shut off. |
| EFI_NOT_FOUND | FilterEvent did not exist. |
