This file declares Vector Handoff Info PPI that describes an array of
|
|
interrupt and/or exception vectors that are in use and need to persist.
|
|
|
|
This is an optional PPI that may be produced by SEC. If present, it provides
|
|
a description of the interrupt and/or exception vectors that were established
|
|
in the SEC Phase and need to persist into PEI and DXE.
