When amdvlk is installed, then VK_ICD_FILENAMES is ignored and AMD_VULKAN_ICD is read instead. However, AMD_VULKAN_ICD does not allow you select pro driver.
The best way to manage this, if you have the 3 types of drivers ( radv, amdvlk and pro) is to
1. disable switchable export DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1
2. set VK_ICD_FILENAMES to the appropriate driver
| Code: |
#!/bin/bash
# This script applies amdvlk-pro/amdvlk/radv Vulkan driver for specific application.
# You can see the list of available drivers with vulkaninfo utility, see the driverName and driverID lines.
#
# Usage:
# <vk_radv|vk_amdvlk|vk_pro> <app and its parameters>
# For example:
# $ vk_pro vkmark
# This will start vkmark with AMDGPU PRO vulkan driver.
# When amdvlk is installed, then VK_ICD_FILENAMES is ignored and AMD_VULKAN_ICD is read instead. However, AMD_VULKAN_ICD does not allow you (afaics) select pro driver.
# So we revert this behavior to standard one.
export DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1
ICD_DIR="/usr/share/vulkan/icd.d"
vk_radv() {
export VK_ICD_FILENAMES="${ICD_DIR}/radeon_icd.i686.json:${ICD_DIR}/radeon_icd.x86_64.json"
}
vk_amdvlk() {
export VK_ICD_FILENAMES="${ICD_DIR}/amd_icd32.json:${ICD_DIR}/amd_icd64.json"
}
vk_pro() {
export VK_ICD_FILENAMES="${ICD_DIR}/amd_pro_icd32.json:${ICD_DIR}/amd_pro_icd64.json"
}
if [[ $(basename $0) == vk_radv ]]; then
vk_radv
elif [[ $(basename $0) == vk_amdvlk ]]; then
vk_amdvlk
elif [[ $(basename $0) == vk_pro ]]; then
vk_pro
else
echo "Unknown function"
exit 1
fi
# applied variables, now execute the rest of the command
