[Mesa-dev] [PATCH 2/2] vulkan/wsi/radv: add initial prime support

Dave Airlie airlied at gmail.com
Tue Feb 21 02:26:30 UTC 2017


From: Dave Airlie <airlied at redhat.com>

This is a complete rewrite of my previous rfc patches.

This adds the ability to present to a different GPU that rendering
using a driver side operation that can copy from the tiled to
linear shared image.

This does prime support completely in the swapchain present code,
and each queue has a precreated command buffer for each image
and for the each queue family. This means presenting should work
on graphics and compute queues and transfer in the future.
