| MISC_SUBCLASS_TABLE_FUNCTION ( | |
| MiscSystemManufacturer | |
| ) | |
| /*++ | |
| Description: | |
| This function makes boot time changes to the contents of the | |
| MiscSystemManufacturer (Type 13). | |
| Parameters: | |
| RecordType | |
| Type of record to be processed from the Data Table. | |
| mMiscSubclassDataTable[].RecordType | |
| RecordLen | |
| Size of static RecordData from the Data Table. | |
| mMiscSubclassDataTable[].RecordLen | |
| RecordData | |
| Pointer to copy of RecordData from the Data Table. Changes made | |
| to this copy will be written to the Data Hub but will not alter | |
| the contents of the static Data Table. | |
| LogRecordData | |
| Set *LogRecordData to TRUE to log RecordData to Data Hub. | |
| Set *LogRecordData to FALSE when there is no more data to log. | |
| Returns: | |
| EFI_SUCCESS | |
| All parameters were valid and *RecordData and *LogRecordData have | |
| been set. | |
| EFI_UNSUPPORTED | |
| Unexpected RecordType value. | |
| EFI_INVALID_PARAMETER | |
| One of the following parameter conditions was true: | |
| RecordLen was zero. | |
| RecordData was NULL. | |
| LogRecordData was NULL. | |
| --*/ | |
| { | |
| STATIC BOOLEAN Done = FALSE; | |

| // First check for invalid parameters. | |

| // | |
| // Then check for unsupported RecordType. | |
| // | |
| if (RecordType != EFI_MISC_SYSTEM_MANUFACTURER_RECORD_NUMBER) { | |
| return EFI_UNSUPPORTED; | |

| // | |
| // Is this the first time through this function? | |
| // | |
| if (!Done) { | |
| // | |
| // Yes, this is the first time. Inspect/Change the contents of the | |
| // RecordData structure. | |

| // Set power-on type. | |
| // | |
| // ((EFI_MISC_SYSTEM_MANUFACTURER_DATA *)RecordData)->SystemWakeupType = %%TBD | |
| // | |
| // Set Done flag to TRUE for next pass through this function. | |
| // Set *LogRecordData to TRUE so data will get logged to Data Hub. | |
| // | |
| Done = TRUE; | |
| *LogRecordData = TRUE; | |
| } else { | |
| // | |
| // No, this is the second time. Reset the state of the Done flag | |
| // to FALSE and tell the data logger that there is no more data | |
| // to be logged for this record type. If any memory allocations | |
| // were made by earlier passes, they must be released now. | |
