PEP_PPM_QUERY_PERF_CAPABILITIES structure (pepfx.h)

The PEP_PPM_QUERY_PERF_CAPABILITIES structure describes the performance capabilities of the processors in the specified processor performance domain.

Syntax

typedef struct _PEP_PPM_QUERY_PERF_CAPABILITIES {
  [out] ULONG HighestPerformance;
  [out] ULONG NominalPerformance;
  [out] ULONG LowestNonlinearPerformance;
  [out] ULONG LowestPerformance;
  [out] ULONG DomainId;
  [out] ULONG DomainMembers;
} PEP_PPM_QUERY_PERF_CAPABILITIES, *PPEP_PPM_QUERY_PERF_CAPABILITIES;

Members

[out] HighestPerformance

The highest performance level in platform-specific units. For more information, see Remarks.

[out] NominalPerformance

The nominal performance level in platform-specific units. For more information, see Remarks.

[out] LowestNonlinearPerformance

The lowest nonlinear performance level in platform-specific units. For more information, see Remarks.

[out] LowestPerformance

The lowest performance level in platform-specific units. For more information, see Remarks.

[out] DomainId

The domain ID of the processor performance domain.

[out] DomainMembers

The number of processors in this performance domain.

Remarks

This structure is used by the PEP_NOTIFY_PPM_QUERY_PERF_CAPABILITIES notification. All six members contain output values that the platform extension plug-in (PEP) writes to the structure in response to this notification.

Processor performance levels are specified in platform-specific units. For example, a hardware platform might use a metric such as the processor clock frequency to provide a rough approximation to the amount of processing work that is being done. For more information, see Platform Performance Thresholds.
