Ubuntu - GPU - Vulkan - Set Vulkan Driver
There are a number of drivers for Vulkan.
Some provide better performance than others.
Drivers include:
- MESA RADV: The Mesa RADV Driver.
- MESA LLVMPIPE: The Mesa LLVMPIPE Driver.
- AMDVLK: The AMD Vulkan Driver.
See Check what Vulkan implementations are currently installed
Set LLVMPIPE as the Vulkan Driver
export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/lvp_icd.x86_64.json:/usr/share/vulkan/icd.d/lvp_icd.i686.json
Check that the driver is being picked up
vulkaninfo | grep driver
returns:
driverVersion = 1 (0x0001) driverID = DRIVER_ID_MESA_LLVMPIPE driverName = llvmpipe driverInfo = Mesa 23.1.2 - kisak-mesa PPA (LLVM 15.0.7) driverUUID = 6c6c766d-7069-7065-5555-494400000000 driverUUID = 6c6c766d-7069-7065-5555-494400000000 driverID = DRIVER_ID_MESA_LLVMPIPE driverName = llvmpipe driverInfo = Mesa 23.1.2 - kisak-mesa PPA (LLVM 15.0.7) VK_KHR_driver_properties : extension revision 1
NOTE: The driverID and other fields here show that the LLVMPIPE driver is being used.

Set MESA RADV as the Vulkan Driver
export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.x86_64.json:/usr/share/vulkan/icd.d/radeon_icd.i686.json
Check that the driver is being picked up
vulkaninfo | grep driver
returns:
driverVersion = 96473090 (0x5c01002) driverID = DRIVER_ID_MESA_RADV driverName = radv driverInfo = Mesa 23.1.2 - kisak-mesa PPA driverUUID = 414d442d-4d45-5341-2d44-525600000000 driverUUID = 414d442d-4d45-5341-2d44-525600000000 driverID = DRIVER_ID_MESA_RADV driverName = radv driverInfo = Mesa 23.1.2 - kisak-mesa PPA VK_KHR_driver_properties : extension revision 1
NOTE: The driverID and other fields here show that the RADV driver is being used.
