167 | Routine Description:\r | |
168 | \r | |
169 | This is the POSTFIX version of the dependency evaluator. When a\r | |
170 | PUSH [PPI GUID] is encountered, a pointer to the GUID is stored on\r | |
171 | the evaluation stack. When that entry is poped from the evaluation\r | |
172 | stack, the PPI is checked if it is installed. This method allows\r | |
173 | some time savings as not all PPIs must be checked for certain\r | |
174 | operation types (AND, OR).\r | |
175 | \r | |
176 | Arguments:\r | |
177 | \r | |
178 | PeiServices - Calling context.\r | |
179 | \r | |
180 | DependencyExpression - Pointer to a dependency expression. The Grammar adheres to\r | |
181 | the BNF described above and is stored in postfix notation.\r | |
182 | Runnable - is True if the driver can be scheduled and False if the driver\r | |
183 | cannot be scheduled. This is the value that the schedulers\r | |
184 | should use for deciding the state of the driver.\r | |

188 | Status = EFI_SUCCESS if it is a well-formed Grammar\r | |
189 | EFI_INVALID_PARAMETER if the dependency expression overflows\r | |
