Vulkan Ecosystem Tools

The repository contains the following Vulkan Tools:

These tools have binaries included within the Vulkan SDK.

Removed Tools

VkTrace and VkReplay have been deprecated and replaced by gfxreconstruct. Both VkTrace and VkReplay have been removed from VulkanTools and can now be found in the vktrace archive. Both these tools are also no longer part of the Vulkan SDK.

Vulkan-Layer-Factory is deprecated and has been archived in its own repository which is available here.

How to Build and Run

BUILD.md includes directions for building all the components and running the tests.

Generated Code

Some of the source code in this repository is generated in layersvt/generated/, from data descriptive headers in the Vulkan-Headers repository.

How to generate the code

scripts/generate_source.py external/Vulkan-Headers/[config]/[architecture]/registry/
     where
config is, for example, 'Debug' or 'Release', and architecture is '64' or '32'.

pwsh -Command { python3 scripts/generate_source.py external/Vulkan-Headers/[config]/[arch]/registry/ }

cmd /C "python3 scripts/generate_source.py external/Vulkan-Headers/[config]/[arch]/registry/"

When making change to the scripts/ folder, make sure to run generate_source.py and check in both the changes to scripts/ and layersvt/generated/ in any PR. (Code generation does not happen automatically at build time.)

CMake helper

A helper CMake target vt_codegen is also provided to simplify the invocation of scripts/generate_source.py from the build directory:

cmake -S . -B build -D VT_CODEGEN=ON
cmake --build build --target vt_codegen

Version Tagging Scheme

Updates to this repository which correspond to a new Vulkan specification release are tagged using the following format: v<version> (e.g., v1.3.266).

Note: Marked version releases have undergone thorough testing but do not imply the same quality level as SDK tags. SDK tags follow the vulkan-sdk-<version>.<patch> format (e.g., vulkan-sdk-1.3.266.0).

This scheme was adopted following the 1.3.266 Vulkan specification release.
