From wikipedia:Vulkan (API):

  Vulkan is a low-overhead, cross-platform 3D graphics and compute API.

Learn more at Khronos.

## Installation

Note: On hybrid graphics (NVIDIA Optimus/AMD Dynamic Switchable Graphics):

- Vulkan is not currently officially supported by Bumblebee [1] but does work with primus_vk or primus-vk-gitAUR.
- The Radeon Vulkan driver now supports PRIME [2].

To run a Vulkan application, you will need to install the vulkan-icd-loader package (and lib32-vulkan-icd-loader if you also want to run 32-bit applications), as well as the Vulkan drivers for your graphics card(s):

- Intel: vulkan-intel (or lib32-vulkan-intel for 32-bit applications)
- NVIDIA: nvidia-utils (or lib32-nvidia-utils)
- AMD: there are three implementations, which could be installed simultaneously:
  - vulkan-radeon (or lib32-vulkan-radeon) - RADV (part of Mesa project)
  - amdvlk (or lib32-amdvlk) - AMDVLK Open (maintained by AMD)
  - vulkan-amdgpu-proAUR (or lib32-vulkan-amdgpu-proAUR) - AMDVLK Closed (maintained by AMD)

Other drivers may be installed manually instead:

- PowerVR: https://imgtec.com/vulkan
- Adreno: https://developer.qualcomm.com/software/adreno-gpu-sdk/gpu

For Vulkan application development, install vulkan-headers, and optionally vulkan-validation-layers and vulkan-tools (you can find the vulkaninfo tool in here).

## Verification

To see which Vulkan implementations are currently installed on your system, use the following command:

    $ ls /usr/share/vulkan/icd.d/

## Vulkan Hardware Database

The Vulkan Hardware Database provides user reported GPU/driver combinations. Supplying own information is possible by using vulkan-caps-viewerAUR.

## Troubleshooting

### Error - vulkan: No DRI3 support

If you get the message above and using Intel graphics, you may need to force DRI3 and restart Xorg:

    /etc/X11/xorg.conf.d/20-intel.conf

    Section "Device"
       Identifier  "Intel Graphics"
       Driver      "intel"
       Option      "DRI"    "3"
    EndSection

### Nvidia - vulkan is not working and can not initialize

Check if you have vulkan-intel installed, it may prevent Nvidia's vulkan driver from being detected.

Alternatively set the environment variable `VK_ICD_FILENAMES` to `/usr/share/vulkan/icd.d/nvidia_icd.json`.

### No device for the display GPU found. Are the intel-mesa drivers installed?

Try to list both the intel_icd and primus_vk_wrapper configurations in VK_ICD_FILENAMES

    export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/intel_icd.x86_64.json:/usr/share/vulkan/icd.d/primus_vk_wrapper.json
