DESCRIPTION: This function retrieves the available driver memory footprint for the specified GPU. If the GPU is in TCC Mode, only dedicatedVideoMemory will be returned in pMemoryInfo (NV_DISPLAY_DRIVER_MEMORY_INFO).
TCC_SUPPORTED
- Since
- Release: 177
- Parameters
-
[in] | hPhysicalGpu | Handle of the physical GPU for which the memory information is to be extracted. |
[out] | pMemoryInfo | The memory footprint available in the driver. See NV_DISPLAY_DRIVER_MEMORY_INFO. |
- Return values
-
NVAPI_INVALID_ARGUMENT | pMemoryInfo is NULL. |
NVAPI_OK | Call successful. |
NVAPI_NVIDIA_DEVICE_NOT_FOUND | No NVIDIA GPU driving a display was found. |
NVAPI_INCOMPATIBLE_STRUCT_VERSION | NV_DISPLAY_DRIVER_MEMORY_INFO structure version mismatch. |
◆ NvAPI_GPU_GetMemoryInfoEx()
DESCRIPTION: This function retrieves the available driver memory footprint for the specified GPU. If the GPU is in TCC Mode, only dedicatedVideoMemory will be returned in pMemoryInfo (NV_GPU_MEMORY_INFO_EX).
SUPPORTED OS: Windows 10 and higher
