Searches the performance measurement log from the beginning of the log for the first matching record that contains a zero end time and fills in a valid end time.
Searches the performance measurement log from the beginning of the log for the first record that matches Handle, Token, and Module, and has an end time value of zero. If the record can not be found then return EFI_NOT_FOUND. If the record is found and TimeStamp is not zero, then the end time in the record is filled in with the value specified by TimeStamp. If the record is found and TimeStamp is zero, then the end time in the matching record is filled in with the current time stamp value.
Handle | The pointer to environment specific context used to identify the component being measured. | |
Token | The pointer to a Null-terminated ASCII string that identifies the component being measured. | |
Module | The pointer to a Null-terminated ASCII string that identifies the module being measured. | |
TimeStamp | The 64-bit time stamp. |
EFI_SUCCESS | The end of the measurement was recorded. | |
EFI_NOT_FOUND | The specified measurement record could not be found. |

Searches the performance measurement log from the beginning of the log for the first matching record that contains a zero end time and fills in a valid end time.
Searches the performance measurement log from the beginning of the log for the first record that matches Handle, Token, Module and Identifier, and has an end time value of zero.

Module | The pointer to a Null-terminated ASCII string that identifies the module being measured. | |
TimeStamp | The 64-bit time stamp. | |
Identifier | 32-bit identifier. If the value is 0, the found record is same as the one found by EndGauge of PERFORMANCE_PROTOCOL. |
EFI_SUCCESS | The end of the measurement was recorded. | |
EFI_NOT_FOUND | The specified measurement record could not be found. |
typedef struct _PERFORMANCE_EX_PROTOCOL PERFORMANCE_EX_PROTOCOL |
typedef EFI_STATUS(EFIAPI * PERFORMANCE_GET_GAUGE)(IN UINTN LogEntryKey, OUT GAUGE_DATA_ENTRY **GaugeDataEntry) |
Retrieves a previously logged performance measurement. It can also retrieve the log created by StartGaugeEx and EndGaugeEx of PERFORMANCE_EX_PROTOCOL, and then eliminate the Identifier.
Retrieves the performance log entry from the performance log specified by LogEntryKey. If it stands for a valid entry, then EFI_SUCCESS is returned and GaugeDataEntry stores the pointer to that entry.
LogEntryKey | The key for the previous performance measurement log entry. If 0, then the first performance measurement log entry is retrieved. | |
GaugeDataEntry | Out parameter for the indirect pointer to the gauge data entry specified by LogEntryKey. |
EFI_SUCCESS | The GuageDataEntry is successfully found based on LogEntryKey. | |
EFI_NOT_FOUND | There is no entry after the measurement referred to by LogEntryKey. | |
EFI_INVALID_PARAMETER | The LogEntryKey is not a valid entry, or GaugeDataEntry is NULL. |
typedef EFI_STATUS(EFIAPI * PERFORMANCE_GET_GAUGE_EX)(IN UINTN LogEntryKey, OUT GAUGE_DATA_ENTRY_EX **GaugeDataEntryEx) |
Retrieves a previously logged performance measurement. It can also retrieve the log created by StartGauge and EndGauge of PERFORMANCE_PROTOCOL, and then assign the Identifier with 0.
Retrieves the performance log entry from the performance log specified by LogEntryKey. If it stands for a valid entry, then EFI_SUCCESS is returned and GaugeDataEntryEx stores the pointer to that entry.
LogEntryKey | The key for the previous performance measurement log entry. If 0, then the first performance measurement log entry is retrieved. | |
GaugeDataEntryEx | Out parameter for the indirect pointer to the extented gauge data entry specified by LogEntryKey. |
EFI_SUCCESS | The GuageDataEntryEx is successfully found based on LogEntryKey. | |
EFI_NOT_FOUND | There is no entry after the measurement referred to by LogEntryKey. | |

typedef struct _PERFORMANCE_PROTOCOL PERFORMANCE_PROTOCOL |
typedef EFI_STATUS(EFIAPI * PERFORMANCE_START_GAUGE)(IN CONST VOID *Handle, IN CONST CHAR8 *Token, IN CONST CHAR8 *Module, IN UINT64 TimeStamp) |
Adds a record at the end of the performance measurement log that records the start time of a performance measurement.
The added record contains the Handle, Token, and Module. The end time of the new record is not recorded, so it is set to zero. If TimeStamp is not zero, then TimeStamp is used to fill in the start time in the record. If TimeStamp is zero, the start time in the record is filled in with the value read from the current time stamp.
Handle | The pointer to environment specific context used to identify the component being measured. | |
Token | The pointer to a Null-terminated ASCII string that identifies the component being measured. | |
Module | The pointer to a Null-terminated ASCII string that identifies the module being measured. | |
TimeStamp | The 64-bit time stamp. |
EFI_SUCCESS | The data was read correctly from the device. | |
EFI_OUT_OF_RESOURCES | There are not enough resources to record the measurement. |
typedef EFI_STATUS(EFIAPI * PERFORMANCE_START_GAUGE_EX)(IN CONST VOID *Handle, IN CONST CHAR8 *Token, IN CONST CHAR8 *Module, IN UINT64 TimeStamp, IN UINT32 Identifier) |
Adds a record at the end of the performance measurement log that records the start time of a performance measurement.
The added record contains the Handle, Token, Module and Identifier. The end time of the new record is not recorded, so it is set to zero. If TimeStamp is not zero, then TimeStamp is used to fill in the start time in the record. If TimeStamp is zero, the start time in the record is filled in with the value read from the current time stamp.
Handle | The pointer to environment specific context used to identify the component being measured. | |
Token | The pointer to a Null-terminated ASCII string that identifies the component being measured. | |
Module | The pointer to a Null-terminated ASCII string that identifies the module being measured. | |
TimeStamp | The 64-bit time stamp. | |
Identifier | 32-bit identifier. If the value is 0, the created record is same as the one created by StartGauge of PERFORMANCE_PROTOCOL. |
EFI_SUCCESS | The data was read correctly from the device. | |
EFI_OUT_OF_RESOURCES | There are not enough resources to record the measurement. |
