struct { ... } NV_GPU_PERF_PSTATES_INFO_V2::clocks[NVAPI_MAX_GPU_PERF_CLOCKS]
NV_GPU_PUBLIC_CLOCK_ID NV_GPU_PERF_PSTATES_INFO_V2::domainId
NV_GPU_PERF_VOLTAGE_INFO_DOMAIN_ID NV_GPU_PERF_PSTATES_INFO_V2::domainId

ID of the voltage domain, containing flags and mvolt info.

NvU32 NV_GPU_PERF_PSTATES_INFO_V2::flags

Reserved for future use. Must be set to 0.

  • bit 0 indicates if perfmon is enabled or not
  • bit 1 indicates if dynamic Pstate is capable or not
  • bit 2 indicates if dynamic Pstate is enable or not
  • all other bits must be set to 0
  • bit 0 indicates if the PCIE limit is GEN1 or GEN2
  • bit 1 indicates if the Pstate is overclocked or not
  • bit 2 indicates if the Pstate is overclockable or not
  • all other bits must be set to 0

bit 0 indicates if this clock is overclockable all other bits must be set to 0

NvU32 NV_GPU_PERF_PSTATES_INFO_V2::freq
NvU32 NV_GPU_PERF_PSTATES_INFO_V2::mvolt

Voltage in mV.

NvU32 NV_GPU_PERF_PSTATES_INFO_V2::numClocks

The number of clock domains supported by each P-State.

NvU32 NV_GPU_PERF_PSTATES_INFO_V2::numPstates

The number of available p-states.

NvU32 NV_GPU_PERF_PSTATES_INFO_V2::numVoltages
NV_GPU_PERF_PSTATE_ID NV_GPU_PERF_PSTATES_INFO_V2::pstateId

ID of the p-state.

struct { ... } NV_GPU_PERF_PSTATES_INFO_V2::pstates[NVAPI_MAX_GPU_PERF_PSTATES]

Valid index range is 0 to numVoltages-1.
