Hi everyone.
I'm doing some tests here with the SMBios protocol, and everything works
correctly at SecMain.exe
But not on a real system.
Follow the function I'm developing
EFI_STATUS GetSmBiosTable(IN INT8 TableType, OUT VOID** SmBiosTable)
{
EFI_STATUS Status = EFI_SUCCESS;
EFI_GUID SMBIOSProtocolGuid = EFI_SMBIOS_PROTOCOL_GUID;
EFI_SMBIOS_PROTOCOL* SmbiosProtocol = NULL;
EFI_SMBIOS_HANDLE SmbiosHandle = (EFI_SMBIOS_HANDLE) 0xFFFE;
EFI_SMBIOS_TABLE_HEADER* SmbiosTableHeader = NULL;
EFI_SMBIOS_TYPE SearchTableType;
BOOLEAN TableDetected = FALSE;
SMBIOS_TABLE_TYPE13* table13 = NULL;
gST->ConOut->OutputString(gST->ConOut, L"GetSmBiosTable begin\r\n");
SearchTableType = TableType;
Status = gBS->LocateProtocol(&SMBIOSProtocolGuid,
NULL,
(VOID**) &SmbiosProtocol);
if(!EFI_ERROR(Status)){
do{
if(SmbiosProtocol != NULL){
Status = SmbiosProtocol->GetNext(SmbiosProtocol,
&SmbiosHandle,
NULL,
&SmbiosTableHeader,
NULL);
if(EFI_ERROR(Status)){
break;
}
if(SmbiosTableHeader->Type == (EFI_SMBIOS_TYPE)TableType){
TableDetected = TRUE;
table13 = (SMBIOS_TABLE_TYPE13 *) &SmbiosTableHeader->Type;
}
}
} while(!TableDetected);
}
return EFI_SUCCESS;
}
On the real system, I always get to the break;
Does any of you see any problem on the call to SmbiosProtocol->GetNext ?
PS.: I removed all the prints from this code and some validations.
Thanks and Regards
Rafael R. Machado
