Psychtoolbox>PsychVulkanCore.{mex*} subfunction

devices = PsychVulkanCore(‘GetDevices’);

Returns an array of structs enumerating all currently available Vulkan driver +
GPU combos.
Each struct in the array describes one combination of Vulkan driver and device,
with the following fields:

‘DeviceIndex’ = Index of the device. Can be used in ‘OpenWindow’ as ‘gpuIndex’.
‘GpuName’ = Name of the Vulkan device / graphics card.
‘GpuDriver’ = Name of the Vulkan driver associated with the device.
‘DriverInfo’ = Additional info associated with the driver, vendor specific.
‘DriverVersion’ = Major.minor.point version string with the driver version.
‘DriverVersionRaw’ = Raw scalar Vulkan driver version.
‘DriverId’ = Id of the type of Vulkan driver: 1 = AMD proprietary, 2 = AMD open
source amdvlk, 3 = AMD OSS Mesa radv, 4 = NVidia proprietary,
5 = Intel proprietary Windows, 6 = Intel OSS Mesa anvil,
13 = Mesa OSS llvmpipe.
‘VendorID’ = Vulkan device vendor id. Typically the PCI vendor id.
‘DeviceID’ = Vulkan device id. Typically the PCI device id.
‘VulkanVersion’ = Major.minor.point version of supported Vulkan api.
‘GpuType’ = Type of device: 0 = Unknown/Other, 1 = Integrated gpu,
2 = Discrete gpu, 3 = Virtual gpu, 4 = cpu, ie. software renderer.

‘SupportsHDR’ = Does the gpu support driving HDR displays in principle?
0 = No, 1 = Basic HDR-10.
‘SupportsTiming’ = Does the gpu support high precision/reliability timing
extensions. 0 = No, 1 = Yes. If the driver does not support
timing extensions, the driver will fall back to hacks.
‘SupportsWait’ = Does the gpu support waiting for present completion: 0 = No, 1
= Yes.
