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
