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

I think some ack for a 2nd use-case, like virtio-wl or whatever would be really cool. To give us some assurance that this is generically useful.
Tomeu? Laurent?
Plus an ack from dma-buf folks (nag them on irc, you don't have them on Cc here).
Hmm, does MAINTAINERS need an update then? Maintainer and mailing lists listed in the "DMA BUFFER SHARING FRAMEWORK" entry are on Cc.
Yeah, maintainers entry with you as maintainer plus dri-devel as mailing list plus drm-misc as repo would be good. Just grep for drm-misc.git for tons of examples.
Who should be Cc'ed?
dim add-missing-cc ftw :-)
Cheers, Daniel
Then this is imo good to go.
I assume you'll push it to drm-misc, like all the other dma-buf stuff?
Can do that, sure, after collecting the acks ...
thanks, Gerd
