Vulkan GPU Work Graphs sample

This branch adds a sample application for VK_AMDX_shader_enqueue extension that provides access to GPU Work Graphs feature on Radeon™ RX 7000 series graphics cards.

To build the sample, follow the standard build instructions.

To run the compute sample, execute with the arguments sample gpu_dispatch. See more details and command line options in the readme.

To run the mesh draw sample, execute with the arguments sample gpu_draw_dispatch. See more details and command line options in the readme.

Renaming Default Branch

We have recently transitioned the repository to use the main branch by default. All remote git usage is handled automatically. To update your local repository to use main please use the following commands

git branch -m master main git fetch origin git branch -u origin/main main git remote set-head origin -a

Introduction

The Vulkan Samples is collection of resources to help you develop optimized Vulkan applications.

If you are new to Vulkan the API samples are the right place to start. Additionally you may find the following links useful:

• Vulkan Guide
• Get Started in Vulkan

Performance samples show the recommended best practice together with real-time profiling information. They are more advanced but also contain a detailed tutorial with more in-detail explanations.

Goals

• Create a collection of resources that demonstrate best-practice recommendations in Vulkan
• Create tutorials that explain the implementation of best-practices and include performance analysis guides
• Create a framework that can be used as reference material and also as a sandbox for advanced experimentation with Vulkan

Samples

• Listing of all samples available in this repository

General information

• Project Basics
  • Controls
  • Debug window
  • Create a Sample
• Vulkan Essentials
  • How does Vulkan compare to OpenGL ES? What should you expect when targeting Vulkan?
• Misc
  • Driver version
  • Memory limits

Setup

Prerequisites: git with git large file storage (git-lfs).

Clone the repo with submodules using the following command:

git clone --recurse-submodules https://github.com/KhronosGroup/Vulkan-Samples.git
cd Vulkan-Samples

Follow build instructions for your platform below.

Usage

The following shows some example command line usage on how to configure and run the Vulkan Samples.

# For the entire usage use
vulkan_samples --help

# For subcommand usage use
vulkan_samples <sub_command> --help

# Run Swapchain Images sample
vulkan_samples sample swapchain_images

# Run AFBC sample in benchmark mode for 5000 frames
vulkan_samples sample afbc --benchmark --stop-after-frame 5000

# Run bonza test offscreen
vulkan_samples test bonza --headless

# Run all the performance samples for 10 seconds in each configuration
vulkan_samples batch --category performance --duration 10

# Run Swapchain Images sample on an Android device
adb shell am start-activity -n com.khronos.vulkan_samples/com.khronos.vulkan_samples.SampleLauncherActivity -e sample swapchain_images
