...gpu_obj(fb->base.obj[0]); Ah, right. Should have noticed this on review.

Just pass it down, the call sites all know it (see patch just sent). cheers, Gerd

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
