Ubuntu - GPU - Vulkan - Vulkan Try New Version

Vulkan applications interact with Vulkan drivers through the loader.

The loader is responsible for supporting multiple GPUs and their drivers.
For supporting the latest Vulkan API version, the loader also needs to be the matching version.

More information about the loader is available here: Vulkan Loader

The upstream Vulkan loader source code is available in the following git repos:

Vulkan Validation Layers

The loader also supports the Vulkan validation layers, which are optional components that augment the Vulkan system.

Layers can intercept, evaluate, and modify existing Vulkan functions on their way from the application down to the hardware.
Layers are a critical component of developing correct Vulkan applications.
More information about the validation layers is available here: Vulkan Validation Layers

Build the loader

sudo apt-get update && sudo apt-get install git build-essential libx11-xcb-dev libxkbcommon-dev libwayland-dev libxrandr-dev cmake
git clone https://github.com/KhronosGroup/Vulkan-Loader.git
cd Vulkan-Loader && mkdir build && cd build
../scripts/update_deps.py
cmake -DCMAKE_BUILD_TYPE=Release -DVULKAN_HEADERS_INSTALL_DIR=$(pwd)/Vulkan-Headers/build/install ..
make -j8

NOTE: Detailed instructions are available in Vulkan-Loader/BUILD.md

Optionally instead of the 2 last lines use this instead:

cmake -C helper.cmake ..
cmake --build .
<code>
 
</WRAP>
 
 
----
 
====== Use the newly built loader ======
 
To use the newly built loader:
 
<code bash>
export LD_LIBRARY_PATH=$(pwd)/loader

Install (Optional)

The newly built loader can be installed to /usr/local/lib by running

sudo make install

Refresh the system loader search cache.

sudo ldconfig

====

Download latest Vulkan-Tools

or

git clone https://github.com/KhronosGroup/Vulkan-Tools.git

Extract to a temporary directory

Chdir to that temporary directory.
