...What I don't understand yet is how we can keep the buffer descriptions together with the protocol data that references them. With SCM_RIGHTS, the FDs are placed in the ancillary data that "travels" together with the protocol data that references them. With the present series, the DRM_IOCTL_VIRTGPU_WINSRV_TX ioctl struct has a field for the protocol data and an array of FDs. How are you proposing to pass instances of that struct from above along the protocol data that refers to them? Thanks, Tomeu

Hi, this work is based on the virtio_wl driver in the ChromeOS kernel by Zach Reizner, currently at: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/virtio/virtio_wl.c There's one feature missing currently, which is letting clients write directly to the host part of a resource, so the extra copy in TRANSFER_TO_HOST isn't needed. Have pushed the
