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