Section Extraction Protocol implementation.
|
|
|
|
Stream database is implemented as a linked list of section streams,
|
|
where each stream contains a linked list of children, which may be leaves or
|
|
encapsulations.
|
|
|
|
Children that are encapsulations generate new stream entries
|
|
when they are created. Streams can also be created by calls to
|
|
SEP->OpenSectionStream().
|
|
|
|
The database is only created far enough to return the requested data from
|
|
any given stream, or to determine that the requested data is not found.
|
|
|
|
If a GUIDed encapsulation is encountered, there are three possiblilites.
|
|
|
|
1) A support protocol is found, in which the stream is simply processed with
|
|
the support protocol.
|
|
|
|
2) A support protocol is not found, but the data is available to be read
|
|
without processing. In this case, the database is built up through the
|
|
recursions to return the data, and a RPN event is set that will enable
|
|
the stream in question to be refreshed if and when the required section
|
|
extraction protocol is published.This insures the AuthenticationStatus
|
|
does not become stale in the cache.
|
|
|
|
3) A support protocol is not found, and the data is not available to be read
|
|
without it. This results in EFI_PROTOCOL_ERROR.
