In this year’s XDC I’ve given a talk about OpenGL and Vulkan interoperability and our work to support EXT_external_objects and EXT_external_objects_fd on different Mesa3D drivers.
These are my slides and pages 9-12 contain short descriptions of all the Piglit EXT_external_objects use cases I plan to describe in the upcoming OpenGL and Vulkan Interoperability blog posts:

This is the second post of the OpenGL and Vulkan interoperability series, where I explain some EXT_external_objects and EXT_external_objects_fd use cases with examples taken by the Piglit tests I’ve written to test the extensions as part of my work for Igalia‘s graphics team.
We are going to see a very simple case of Vulkan/GL interoperability where an image is allocated using Vulkan and filled using OpenGL. This case is implemented in Piglit’s vk-image-overwrite test for images of different formats.
It’s been a while that Igalia’s graphics team had been working on the OpenGL extensions that provide the mechanisms for OpenGL and Vulkan interoperability in the Intel iris (gallium3d) driver that is part of mesa.
As there were no conformance tests (CTS) for this extension, and we needed to test it, we have written (and we are still writing) small tests for piglit that allow the exchange and the synchronization of the exchange of resources such as buffers, textures, and depth or stencil buffers.
