Struct CuLaunchConfig 

#[repr(C)]
pub struct CuLaunchConfig {
    pub grid_dim_x: u32,
    pub grid_dim_y: u32,
    pub grid_dim_z: u32,
    pub block_dim_x: u32,
    pub block_dim_y: u32,
    pub block_dim_z: u32,
    pub shared_mem_bytes: u32,
    pub stream: CUstream,
    pub attrs: *const CuLaunchAttribute,
    pub num_attrs: u32,
}

Extended kernel launch configuration for cuLaunchKernelEx (CUDA 12.0+).

Supersedes the individual parameters of cuLaunchKernel and adds support for thread block clusters, launch priorities, and other CUDA 12.x features.

Example

use oxicuda_driver::ffi::{
    CuLaunchConfig, CuLaunchAttribute, CuLaunchAttributeId,
    CuLaunchAttributeValue, CuLaunchAttributeClusterDim, CUstream,
};

// Build a cluster-launch config for a 2×1×1 cluster.
let cluster_attr = CuLaunchAttribute {
    id: CuLaunchAttributeId::ClusterDimension,
    pad: [0u8; 4],
    value: CuLaunchAttributeValue {
        cluster_dim: CuLaunchAttributeClusterDim { x: 2, y: 1, z: 1 },
    },
};
let _config = CuLaunchConfig {
    grid_dim_x: 8,
    grid_dim_y: 1,
    grid_dim_z: 1,
    block_dim_x: 256,
    block_dim_y: 1,
    block_dim_z: 1,
    shared_mem_bytes: 0,
    stream: CUstream::default(),
    attrs: std::ptr::null(),
    num_attrs: 0,
};
