Field Documentation

struct { ... } NV_GPU_PERF_PSTATES_INFO_V1::clocks[NVAPI_MAX_GPU_PERF_CLOCKS]

NV_GPU_PUBLIC_CLOCK_ID NV_GPU_PERF_PSTATES_INFO_V1::domainId

ID of the clock domain.

NvU32 NV_GPU_PERF_PSTATES_INFO_V1::flags

Reserved. 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

NvU32 NV_GPU_PERF_PSTATES_INFO_V1::freq

Clock frequency in kHz.

NvU32 NV_GPU_PERF_PSTATES_INFO_V1::numClocks

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

NvU32 NV_GPU_PERF_PSTATES_INFO_V1::numPstates

The number of available p-states.

NV_GPU_PERF_PSTATE_ID NV_GPU_PERF_PSTATES_INFO_V1::pstateId

ID of the p-state.
