2018-12-13	fix dma-buf/udmabuf selftest	Tom Murphy	1	-0/+2
	This patch fixes the udmabuf selftest. Currently the selftest is broken. I fixed the selftest by setting the F_SEAL_SHRINK seal on the memfd file descriptor which is required by udmabuf and added the test to the selftest Makefile.

2018-09-03	Add udmabuf misc device	Gerd Hoffmann	1	-0/+5
	A driver to let userspace turn memfd regions into dma-bufs. Use case: Allows qemu create dmabufs for the vga framebuffer or virtio-gpu ressources. Then they can be passed around to display those guest things on the host. To spice client for classic full framebuffer display, and hopefully some day to wayland server for seamless guest window display. qemu test branch: https://git.kraxel.org/cgit/qemu/log/?h=sirius/udmabuf Cc: David Airlie <airlied@linux.ie> Cc: Tomeu Vizoso <tomeu.vizoso@collabora.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20180827093444.23623-1-kraxel@redhat.com
