Module Name:
MiscSystemManufacturerFunction.c
Abstract:
This driver parses the mMiscSubclassDataTable structure and reports
any generated data to the DataHub.
--*/
#include "MiscSubclassDriver.h"
//
//
//
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.
//
if (*RecordLen == 0 || RecordData == NULL || LogRecordData == NULL) {
return EFI_INVALID_PARAMETER;
}
//
// 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 system GUID.
//
// ((EFI_MISC_SYSTEM_MANUFACTURER_DATA *)RecordData)->SystemUuid = %%TBD
//
// 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.
//
Done = FALSE;
*LogRecordData = FALSE;
