Bridging the OpenGL and Vulkan divide

Filed under

Thanks to a new, low overhead extension in Mesa, OpenGL and Vulkan applications can now talk to each other, bringing more flexibility to application developers while easing the transition path between the industry-standard Khronos® APIs.

After several months of work, I'm excited to present a way for OpenGL and Vulkan applications to talk to each other when using Mesa.

Quoting from Khronos's own website, Vulkan promises to be a "new generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs". However, as with all new API's, rewrites of any graphics applications leveraging Vulkan are going to be slow process. And not all applications might want to make the switch.

Since Vulkan offers higher efficiency and features missing in OpenGL, an application developer could however choose to rewrite performance critical sections in Vulkan, while keeping other parts in OpenGL for the sake of convenience. This would need a way for OpenGL and Vulkan to talk to each other. As of late 2016, this was formalized in the EXT_external_objects spec that defines primitives for exchanging buffers and syncrhonization primitives between OpenGL and Vulkan.

Intel's OpenGL Mesa Drivers Now In Good Shape...

  • Intel's OpenGL Mesa Drivers Now In Good Shape For External Objects

    Over the past year developers from Igalia, Collabora, and others have been involved in bringing up support for the OpenGL EXT_external_objects extension within the Intel open-source drivers. That work is now squared away as one of the pieces for offering better interoperability between OpenGL and Vulkan.

    Last month the EXT_external_objects support for the Intel Iris Gallium3D driver was merged. Additionally, merged a few weeks back was EXT_external_objects support for the aging i965 Mesa driver that continues providing OpenGL support for pre-Broadwell hardware.

  • OpenGL and Vulkan applications can now talk to each other with Mesa drivers

    Not specifically gaming related but we love to cover industry stuff too, that might be interesting for some of our more technically minded users. Collabora have mentioned that thanks to work done on Mesa, OpenGL and Vulkan applications can now talk to each other.

    While Vulkan is the next-generation, and eventually anything that wants performance will move over from OpenGL like applications, game engines and games - this all takes time. The bigger games especially, often taking a great many years and an API switch isn't an easy thing. However, what if some parts could gradually move to Vulkan while keeping other bits OpenGL?

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
