Due to performance, uadk tries to leave many configuration options to users. This gives users great flexibility, but it also leads to a problem that the current initialization interface has high complexity. Therefore, in order to facilitate users to adapt quickly, a new set of interfaces is provided.
The 'wd_alg_init2()' will complete all initialization steps. There are 4 parameters to describe the user configuration requirements. @device_list: The available uacce device list. Users can get it by wd_get_accel_list(). @numa_bitmask: The bitmask provided by libnuma. Users can use this parameter to control requesting ctxs devices in the bind NUMA scenario. @ctx_nums: The requested ctx number for each numa node. Due to users may have different requirements for different types of ctx numbers, needs a two-dimensional array as input. @sched_type: Scheduling type the user wants to use.
