2 | Performance library instance used by SMM Core.\r | |
3 | \r | |
4 | This library provides the performance measurement interfaces and initializes performance\r | |
5 | logging for the SMM phase.\r | |
f0da4d7d | 6 | It initializes SMM phase performance logging by publishing the SMM Performance and PerformanceEx Protocol,\r |
d042c6e8 | 7 | which is consumed by SmmPerformanceLib to logging performance data in SMM phase.\r |
8 | \r | |
9 | This library is mainly used by SMM Core to start performance logging to ensure that\r | |
f0da4d7d | 10 | SMM Performance and PerformanceEx Protocol are installed at the very beginning of SMM phase.\r |
d042c6e8 | 11 | \r |
ccd2f6b0 | 12 | Caution: This module requires additional review when modified.\r |
13 | This driver will have external input - performance data and communicate buffer in SMM mode.\r | |
14 | This external input must be validated carefully to avoid security issue like\r | |
15 | buffer overflow, integer overflow.\r | |
16 | \r | |
17 | SmmPerformanceHandlerEx(), SmmPerformanceHandler() will receive untrusted input and do basic validation.\r | |

1247 | Attempts to retrieve the performance log entry specified by LogEntryKey. If LogEntryKey is\r |
1248 | zero on entry, then an attempt is made to retrieve the first entry from the performance log,\r | |
1249 | and the key for the second entry in the log is returned. If the performance log is empty,\r | |
1250 | then no entry is retrieved and zero is returned. If LogEntryKey is not zero, then the performance\r | |
1251 | log entry associated with LogEntryKey is retrieved, and the key for the next entry in the log is\r | |
1252 | returned. If LogEntryKey is the key for the last entry in the log, then the last log entry is\r | |
1253 | retrieved and an implementation specific non-zero key value that specifies the end of the performance\r | |
1254 | log is returned. If LogEntryKey is equal this implementation specific non-zero key value, then no entry\r | |
