Typedefs

typedef void \* ov::intel_gpu::ocl::gpu_handle_param

Shortcut for defining a handle parameter.

Global Variables

static constexpr Property<ContextType> ov::intel_gpu::context_type {"CONTEXT_TYPE"}

Shared device context type: can be either pure OpenCL (OCL) or shared video decoder (VA_SHARED) context.

static constexpr Property<gpu_handle_param> ov::intel_gpu::ocl_context {"OCL_CONTEXT"}

This key identifies OpenCL context handle in a shared context or shared memory blob parameter map.

static constexpr Property<int> ov::intel_gpu::ocl_context_device_id {"OCL_CONTEXT_DEVICE_ID"}

This key identifies ID of device in OpenCL context if multiple devices are present in the context.

static constexpr Property<int> ov::intel_gpu::tile_id {"TILE_ID"}

In case of multi-tile system, this key identifies tile within given context.

static constexpr Property<gpu_handle_param> ov::intel_gpu::ocl_queue {"OCL_QUEUE"}

This key identifies OpenCL queue handle in a shared context.

static constexpr Property<gpu_handle_param> ov::intel_gpu::va_device {"VA_DEVICE"}

This key identifies video acceleration device/display handle in a shared context or shared memory blob parameter map.

static constexpr Property<SharedMemType> ov::intel_gpu::shared_mem_type {"SHARED_MEM_TYPE"}

This key identifies type of internal shared memory in a shared memory blob parameter map.

static constexpr Property<gpu_handle_param> ov::intel_gpu::mem_handle {"MEM_HANDLE"}

This key identifies OpenCL memory handle in a shared memory blob parameter map.

static constexpr Property<gpu_handle_param> ov::intel_gpu::dev_object_handle {"DEV_OBJECT_HANDLE"}

This key identifies video decoder surface handle in a shared memory blob parameter map.

static constexpr Property<uint32_t> ov::intel_gpu::va_plane {"VA_PLANE"}

This key identifies video decoder surface plane in a shared memory blob parameter map.
