| 2 | This file declares Vector Handoff Info PPI that describes an array of\r | |
| 3 | interrupt and/or exception vectors that are in use and need to persist.\r | |
| 4 | \r | |
| 5 | This is an optional PPI that may be produced by SEC. If present, it provides\r | |
| 6 | a description of the interrupt and/or exception vectors that were established\r | |
| 9095d37b | 7 | in the SEC Phase and need to persist into PEI and DXE.\r |
