| 2 | Provides CPU architecture specific functions that can not be defined
|
| 3 | in the Base Library due to dependencies on the PAL Library
|
| 4 |
|
| 5 | The CPU Library provides services to flush CPU TLBs and place the CPU in a sleep state.
|
| 6 | The implementation of these services on Itanium processors requires the use of PAL Calls.
|
| 7 | PAL Calls require PEI and DXE specific mechanisms to look up PAL Entry Point.
|
| 8 | As a result, these services could not be defined in the Base Library.
