50a64e5b | 2 | Provides CPU architecture specific functions that can not be defined\r |
3 | in the Base Library due to dependencies on the PAL Library\r | |
d80b2f71 | 4 | \r |
5 | The CPU Library provides services to flush CPU TLBs and place the CPU in a sleep state.\r | |
1a2f870c | 6 | The implementation of these services on Itanium processors requires the use of PAL Calls.\r |
d80b2f71 | 7 | PAL Calls require PEI and DXE specific mechanisms to look up PAL Entry Point.\r |
8 | As a result, these services could not be defined in the Base Library.\r | |
