If by that you mean whether I was able to use all commands in the
'apropos lx' list, then yes, it seems to work. Here's an arbitrary example:

(gdb) set $p = $lx_task_by_pid(12)
(gdb) p $lx_thread_info($p)
$8 = {task = 0xffff88007bcedb40, exec_domain = 0xffffffff8186c8a0 <default_exec_domain>, flags = 0, status = 0, cpu = 1, 
  saved_preempt_count = -2147483646, addr_limit = {seg = 18446744073709551615}, restart_block = {
    fn = 0xffffffff8105c3c0 <do_no_restart_syscall>, {futex = {uaddr = 0x0 <irq_stack_union>, val = 0, flags = 0, bitset = 0, time = 0, 
        uaddr2 = 0x0 <irq_stack_union>}, nanosleep = {clockid = 0, rmtp = 0x0 <irq_stack_union>, compat_rmtp = 0x0 <irq_stack_union>, 
        expires = 0}, poll = {ufds = 0x0 <irq_stack_union>, nfds = 0, has_timeout = 0, tv_sec = 0, tv_nsec = 0}}}, 
  sysenter_return = 0x0 <irq_stack_union>, sig_on_uaccess_error = 0, uaccess_err = 0}
