[PATCH 0/7] RFCv3 VGEM Prime (dma-buf)

[Ben Widawsky <ben@bwidawsk.net>]

I'm going to be off doing other things for the next couple of weeks, so
I'm dropping these now to give it a nice soak while I'm gone.

Dave/Daniel: if you could look these over and tell me if the general
direction seems good.

Ajax: anything you missing in the basic vgem stuff?

Since the last time:
Squashed down the original vgem patches
Use dumb_bo functions/ditched VGEM ioctls
Hooked up prime import and export support

On the prime side, the major difference from what Dave has done before
is a per driver hash of the previously used dma bufs/gem objects.

The prime stuff is of particularly low quality at this point, like I
said, trying to get something out before I disappear for a while. So
please don't yell at me about obvious bugs :). After getting feedback on
what I have now, I will incorporate Dave's earlier work on i915 prime,
and get some better test cases going.

On my todos:
Ascii chart of dmabuf/drm object life cycle
hashsify the per file list
i915 per driver hash
vgem-i915 and vice versa test cases

As before, the very basic tools are here:
git://people.freedesktop.org/~bwidawsk/vgem-gpu-tools

Once we get cpu maps that I think Daniel wants to work on, I can even do
better tests with just VGEM.

Adam Jackson (1):
  drm/vgem: virtual GEM provider

Ben Widawsky (5):
  drm: DRM_DEBUG_PRIME
  drm: per device prime dma buf hash
  drm/vgem: prime export support
  drm/vgem: import support
  drm: actually enable PRIME

Dave Airlie (1):
  drm: base prime support
