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

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

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
|

|
||||
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.

Register an event handler with the Data Hub to parse EFI_DEBUG_CODE. This

handler reads the Data Hub and sends any DEBUG info to StdErr.

Arguments:

ImageHandle - Image handle of this driver.

SystemTable - Pointer to EFI system table.

Returns:
|

|
||||
EFI_SUCCESS - The event handler was registered.
|
||||
EFI_OUT_OF_RESOURCES - The event hadler was not registered due to lack of
|
||||
system resources.
