DXGK_ADAPTER_PERFDATACAPS structure (d3dkmdt.h)
The DXGK_ADAPTER_PERFDATACAPS structure describes the performance data capabilities of the adapter.
Syntax
typedef struct _DXGK_ADAPTER_PERFDATACAPS {
ULONGLONG MaxMemoryBandwidth;
ULONGLONG MaxPCIEBandwidth;
ULONG MaxFanRPM;
ULONG TemperatureMax;
ULONG TemperatureWarning;
} DXGK_ADAPTER_PERFDATACAPS;
Members
MaxMemoryBandwidth
The maximum memory bandwidth in bytes for 1 second.
MaxPCIEBandwidth
The maximum PCIE bandwidth in bytes for 1 second.
MaxFanRPM
The maximum fan revolutions per minute of the main fan.
TemperatureMax
The maximum temperature before damage levels occur in deci-Celsius (a value of 1 = 0.1C).
TemperatureWarning
The temperature level where temperature based throttling begins in deci-Celsius (a value of 1 = 0.1C).
Remarks
KMD's DxgkDdiQueryAdapterInfo function should fill in the DXGK_ADAPTER_PERFDATACAPS structure in response to a DXGK_QUERYADAPTERINFOTYPE query of type DXGKQAITYPE_ADAPTERPERFDATA_CAPS.
