-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

- After the FilterEvent is registered, it will be signaled so it can sync

-
-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.
