Hi! It seems like prime_handle_from_fd needs to be paired with a GEM_CLOSE ioctl instead of a new generic HANDLE_CLOSE ioctl.
This oversight is not really a big problem but there are two solutions: 1) Create a new ioctl called HANDLE_CLOSE or something similar. 2) Use the GEM_CLOSE ioctl, but add a driver callback for drivers that are not GEM-aware. It seems like GEM_CLOSE has already spread into user-space clients, so unless someone tell me otherwise, I'll be using 2) for the vmwgfx prime implementation. Thanks, Thomas
