    Field Documentation

    ◆ eventId

    NvRmGpuDeviceEventId NvRmGpuDeviceEventInfoRec::eventId

    Event type.

    Definition at line 1995 of file nvrm_gpu.h.

    ◆ timeNs

    uint64_t NvRmGpuDeviceEventInfoRec::timeNs

    GPU time (in nanoseconds)

    This is the unscaled GPU PTIMER timestamp at the occurrence of the event.

    Remarks
    Certain integrated Tegra GPUs require GPU timestamp scaling. These GPUs are T210 and T214. See the discussion in NvRmGpuDeviceInfo::ptimerScaleNumerator for further details.
