<H2><A NAME="s7">7. CLI/STI & spin locking</A></H2>
<P>Good code shouldn't contains <I>snd_cli()</I>/<I>snd_sti()</I> calls.
Use rather spin locks <I>snd_spin_lock()</I>/<I>snd_spin_unlock()</I>
for locking some code. This code is much better for SMP machines.</P>
<P><B>Note:</B> Debugging code is available and it should be enabled in
<I>sndspinlock.h</I>.</P>
