Module device 

OIDN logical device (CPU or GPU backend) and physical device queries. Full API: type-based and physical-ID/UUID/LUID/PCI/CUDA/HIP/Metal device creation.

Structs

OidnDevice

Open Image Denoise logical device.

Enums

OidnDeviceType

OIDN device type (CPU, GPU backends, or default auto-select).

Functions

get_physical_device_bool

Returns a boolean parameter of the physical device. name is e.g. "type", "name".

get_physical_device_data

Returns opaque data and its size for the physical device. Pointer valid until next OIDN call.

get_physical_device_int

Returns an integer parameter of the physical device.

get_physical_device_string

Returns a string parameter of the physical device. Pointer valid until next OIDN call.

is_cpu_device_supported

Whether the CPU device is supported.

is_cuda_device_supported

Whether the given CUDA device ID is supported.

is_hip_device_supported

Whether the given HIP device ID is supported.

is_metal_device_supported^⚠

Whether the given Metal device (MTLDevice, passed as raw pointer) is supported.

num_physical_devices

Number of physical devices supported by OIDN. Valid IDs are 0 .. num_physical_devices().

take_global_error

Returns the first unqueried error for the current thread (e.g. from a failed device creation) and clears it. Can be called without a device to check why OidnDevice::new() or similar failed.
