From: Dave Airlie <airl...@redhat.com>
This is a repost of the prime support with some minor changes,
you no longer need to set DRI_PRIME for this code to figure out
it's on a different GPU and do the linear transfers.
In order to decide the default GPU I'll have to write a layer
so I'll try and get to that soon.
This creates a linear shadow image in GART that gets blitted to at the
image transition. We shouldn't have to add two pointers to every image, but my
other
attempts at this were ugly.
v2: move to testing the dri3 fd to decide if we are a different
GPU, dont need to set DRI_PRIME for the driver now.
TODO:
this would use SDMA on a transfer queue, I'll get back to that
when I have transfer queues merged.
Is the image transition the proper place to hack this in? not
really sure anywhere else is appropriate. nha says no, and
he's probably right so once I have transfer working I'll create
some command buffers at swapchain present time.
