Do I Need To Download The Vulcan Amio Auto Updater

From wikipedia:Vulkan (API):

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

Learn more at Khronos.

Installation

To run a Vulkan application, you will demand to install the vulkan-icd-loader package (and lib32-vulkan-icd-loader if y'all likewise desire to run 32-chip applications), besides as Vulkan drivers for your graphics card(s). There are several packages providing a vulkan-driver:

Intel: vulkan-intel (or lib32-vulkan-intel)
NVIDIA: nvidia-utils (or lib32-nvidia-utils)
AMD: there are three implementations, which could exist installed simultaneously:
- vulkan-radeon (or lib32-vulkan-radeon) - RADV (role of Mesa project)
- amdvlk (or lib32-amdvlk) - AMDVLK Open (maintained by AMD)
- vulkan-amdgpu-pro ^AUR (or lib32-vulkan-amdgpu-pro ^AUR) - AMDVLK Closed (maintained by AMD)

Other drivers may exist installed manually instead:

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

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

Verification

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

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

To ensure that Vulkan is working with your hardware, install vulkan-tools and use the vulkaninfo command to pull up relevant information well-nigh your organization. If yous become info about your graphics card, yous will know that Vulkan is working.

$ vulkaninfo

You tin see https://linuxconfig.org/install-and-examination-vulkan-on-linux for more information.

Selecting Vulkan driver

In some cases, multiple vulkan driver are installed (for example RADV and AMDVLK). Equally of amdvlk 2021.Q3.4, a new switching logic was implemented which enforces AMDVLK every bit the default and mandates you either

set AMD_VULKAN_ICD=RADV to switch from the AMDVLK default,
or globally set DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=i to re-enable the ICD loader method below.

When DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1, you tin can choose your preferred driver by setting the environs variable VK_ICD_FILENAMES. For example, running Steam with the RADV driver is done by

$ VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json steam

To avoid crashes with 32-scrap games, information technology is possible to assign the 32-bit variant and the 64-bit variant to the environs variable.

AMD_VULKAN_ICD seems to not support selecting pro vulkan. But you tin can install amd-vulkan-prefixes ^AUR and easily switch between all three implementations without the demand of specifying long pathes manually. You need to prepend your application with the prefix you lot want. For example:

$ vk_pro basemark

Software Vulkan: lavapipe

Yous can also install the software Vulkan rasterizer known equally lavapipe: vulkan-swrast. At that place is no 32-bit vulkan-swrast bundle for at present (even in AUR).

Alarm: "lavapipe is not a conformant Vulkan implementation, testing use only." (quoted from the commuter itself)

$ LIBGL_ALWAYS_SOFTWARE=1 __GLX_VENDOR_LIBRARY_NAME=mesa VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/lvp_icd.i686.json:/usr/share/vulkan/icd.d/lvp_icd.x86_64.json vulkaninfo

Vulkan hardware database

The Vulkan Hardware Database provides user reported GPU/driver combinations. Supplying own information is possible by using vulkan-caps-viewer-wayland ^AUR or vulkan-caps-viewer-x11 ^AUR.

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/twenty-intel.conf

Section "Device"    Identifier  "Intel Graphics"    Commuter      "intel"    Pick      "DRI"    "3" EndSection

Nvidia - vulkan is not working and tin can not initialize

Check if you have any other vulkan driver installed, it may prevent Nvidia's vulkan driver from existence detected.

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

If you lot take a dual-graphics organisation, like NVIDIA Optimus, ensure that your system is using the graphics card that yous installed Vulkan drivers for.

The factual accurateness of this article or department is disputed.

Reason: optimus-director is just 1 of several utilities for NVIDIA Optimus. (Talk over in Talk:Vulkan)

This commodity or section needs linguistic communication, wiki syntax or mode improvements. See Help:Style for reference.

optimus-manager --status

Optimus Managing director (Client) version i.4  Electric current GPU mode : nvidia GPU mode requested for next login : no alter GPU at startup : integrated Temporary config path: no

No device for the brandish GPU constitute. Are the intel-mesa drivers installed?

Try to listing 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/nv_vulkan_wrapper.json

AMDGPU - ERROR_INITIALIZATION_FAILED after vulkaninfo

If later running vulkaninfo on AMD card from GCN1 or GCN2 family you got fault message like:

Error at /build/vulkan-tools/src/Vulkan-Tools-1.2.135/vulkaninfo/vulkaninfo.h:240:vkEnumerateInstanceExtensionProperties failed with ERROR_INITIALIZATION_FAILED

So check if y'all take correctly enable support for this models of graphics cards (AMDGPU#Enable Southern Islands (SI) and Sea Islands (CIK) support).

One of possibility to check if gpu drivers are correctly loaded is lspci -k, after running this command check kernel driver of your gpu. Information technology should be amdgpu.

$ lspci -thousand
