The swp{b} instruction is deprecated in ARMv6 and above. Worse, it isn't supported at all in ARMv7 and is fixed up in the illegal instruction trap in the Linux kernel - at some runtime cost. Your compiler should absolutely not be generating it. Since raspi is armb6 arch - this warning will be silently ignored, but if you'll build on cubieboard (A10/A20) - it will be a catastrophe.<br>
</div><div><br></div><div>Regarding to SMP to ARMv6 - there is no SMP support. The SMP is only above ARM9.<br><br></div><div><br><br></div><div> <br></div></div><br></div><div><div><div class="gmail_extra">
