e310a27b | 31 | This function is the entry point to the DXE Foundation. The PEI phase, which executes just before\r |
32 | DXE, is responsible for loading and invoking the DXE Foundation in system memory. The only\r | |
33 | parameter that is passed to the DXE Foundation is HobStart. This parameter is a pointer to the\r | |
34 | HOB list that describes the system state at the hand-off to the DXE Foundation. At a minimum,\r | |
35 | this system state must include the following:\r | |
36 | - PHIT HOB\r | |
37 | - CPU HOB\r | |
38 | - Description of system memory\r | |
39 | - Description of one or more firmware volumes\r | |
40 | The DXE Foundation is also guaranteed that only one processor is running and that the processor is\r | |
41 | running with interrupts disabled. The implementation of the DXE Foundation must not make any\r | |
42 | assumptions about where the DXE Foundation will be loaded or where the stack is located. In\r | |
43 | general, the DXE Foundation should make as few assumptions about the state of the system as\r | |
44 | possible. This lack of assumptions will allow the DXE Foundation to be portable to the widest\r | |
45 | variety of system architectures.\r | |
