Hades (PPSA03355) stops at load on main with "undefined symbol: 9HzfhdtESio", the NID of pthread_getname_np, which it calls on pthread_self() with a 32-byte buffer. Measured on a PS5 (firmware 13.60) through dlopen of libkernel: the function takes (thread, buffer), copies the name and its terminator, returns an empty name for an unnamed thread, ESRCH for a null or joined thread and EFAULT for a null buffer.
