Function nvapi_sys::gpu::pstate::NvAPI_GPU_GetDynamicPstatesInfoEx

pub unsafe fn NvAPI_GPU_GetDynamicPstatesInfoEx(
    hPhysicalGPU: NvPhysicalGpuHandle, 
    pDynamicPstatesInfoEx: *mut NV_GPU_DYNAMIC_PSTATES_INFO_EX
) -> NvAPI_Status

This API retrieves the NV_GPU_DYNAMIC_PSTATES_INFO_EX structure for the specified physical GPU.

Each domain's info is indexed in the array. For example:

• pDynamicPstatesInfo->utilizationNVAPI_GPU_UTILIZATION_DOMAIN_GPU holds the info for the GPU domain.

There are currently 4 domains for which GPU utilization and dynamic P-State thresholds can be retrieved:

• graphic engine (GPU)
• frame buffer (FB)
• video engine (VID)
• bus interface (BUS)
