Module kind 

Backing store kind, as reported in TensorDesc::kind.

Constants

CUDA_DEVICE

CUDA device memory. ptr is a device pointer, not host-addressable.

D3D11_TEXTURE

Windows D3D11 texture. handle is the texture’s NT shared handle and ptr the device fence’s NT shared handle, both valid in the producing process (other modules of the same process included); sync is the fence value of the last recorded GPU write when SYNC_PRESENT is set. The ptr reuse follows PBO’s vtable precedent.

DMABUF

Linux dma-buf. handle is the fd.

HOST

Host memory: Mem or Shm. ptr is valid; handle is -1.

IOSURFACE

Apple IOSurface. handle is the surface id.

PBO

OpenGL pixel buffer object. handle is the buffer id.
