Module Name:
DataHub.c
Abstract:
This code produces the Data Hub protocol. It preloads the data hub
with status information copied in from PEI HOBs.
Only code that implements the Data Hub protocol should go in this file!
The Term MTC stands for MonoTonicCounter.
For more information please look at DataHub.doc
NOTE: For extra security of the log GetNextDataRecord () could return a copy
of the data record.

/*++
Routine Description:
Get a previously logged data record and the MonotonicCount for the next
availible Record. This allows all records or all records later
than a give MonotonicCount to be returned. If an optional FilterDriverEvent
is passed in with a MonotonicCout of zero return the first record
not yet read by the filter driver. If FilterDriverEvent is NULL and
MonotonicCount is zero return the first data record.
Arguments:
This - The EFI_DATA_HUB_PROTOCOL instance.
MonotonicCount - Specifies the Record to return. On input, zero means
return the first record. On output, contains the next
record to availible. Zero indicates no more records.
FilterDriverEvent - If FilterDriverEvent is not passed in a MonotonicCount
of zero, it means to return the first data record.
If FilterDriverEvent is passed in, then a MonotonicCount
of zero means to return the first data not yet read by
FilterDriverEvent.
Record - Returns a dynamically allocated memory buffer with a data
record that matches MonotonicCount.
Returns:
EFI_SUCCESS - Data was returned in Record.
EFI_INVALID_PARAMETER - FilterDriverEvent 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.

/*++
Routine Description:
This function registers the data hub filter driver that is represented
by FilterEvent. Only one instance of each FilterEvent can be registered.
After the FilterEvent is registered, it will be signaled so it can sync
with data records that have been recorded prior to the FilterEvent being
registered.
Arguments:
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.
Returns:
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.
