A new option has been added to Vkrunner (the Vulkan shader testing tool written by Neil Roberts) to allow selecting the Vulkan device for each shader test.

A simple pixel shader viewer
In a previous post, I wrote about Vkrunner, and how I used it to play with fragment shaders. While I was writing the shaders for it, I had to save them, generate a PPM image and display it to see the changes. This render to image/display repetition gave me the idea to write a minimal tool that automatically displays my changes every time I save the file with the shader code and use it when the complexity of the scene is increasing. And so, I’ve written sdrviewer, the minimal OpenGL viewer for pixel shaders of the video below:
Vkrunner allows specifying the required Vulkan version
The required Vulkan implementation version for a Vkrunner shader test can now be specified in its [require] section. Tests that are targeting Vulkan versions that aren’t supported by the device driver will be skipped.

Having fun with Vkrunner!
Vkrunner is a Vulkan shader testing tool similar to Piglit, written by Neil Roberts. It is mostly used by graphics drivers developers, and was also part of the official Khronos conformance tests suite repository (VK-GL-CTS) for some time [1]. There are already posts [2] about its use but they are all written from a driver developer’s perspective and focus on vkrunner’s debugging capabilities. In this post, I’m going to show you an alternative use I’ve found for it, in order to have fun with pixel shaders during my holidays! 🙂
