216 | Routine Description:\r | |
217 | \r | |
218 | This is the POSTFIX version of the dependency evaluator. When a\r | |
219 | PUSH [PPI GUID] is encountered, a pointer to the GUID is stored on\r | |
220 | the evaluation stack. When that entry is poped from the evaluation\r | |
221 | stack, the PPI is checked if it is installed. This method allows\r | |
222 | some time savings as not all PPIs must be checked for certain\r | |
223 | operation types (AND, OR).\r | |

225 | Arguments:\r | |

227 | PeiServices - Calling context.\r | |

230 | the BNF described above and is stored in postfix notation.\r | |
231 | Runnable - is True if the driver can be scheduled and False if the driver\r | |
232 | cannot be scheduled. This is the value that the schedulers\r | |
233 | should use for deciding the state of the driver.\r | |
