+
+    <body>
+      <p>Since the previous report, ThunderX gained SMP support and
+	&os; is now running on 48 real-life ARMv8 CPU cores!  The
+	newly introduced functionality was based on initial
+	foundational work submitted by Andrew Turner and Robin
+	Randhawa, with emulation as the primary target.</p>
+
+      <p>Semihalf's efforts focused on hardware, and include:</p>
+
+      <ul>
+	<li>Multicore support for the newer Generic Interrupt
+	  Controller GICv3</li>
+
+	<li>Numerous bug fixes for:
+	  <ul>
+	    <li><tt>pmap(9)</tt> - memory attributes and TLB
+	    management</li>
+
+	    <li><tt>locore.S</tt> - secondary core initialization</li>
+
+	    <li>IPI (inter-processor interrupts)</li>
+
+	    <li>Per-CPU timers</li>
+
+	    <li>Size of early UMA allocations</li>
+
+	    <li>Cache maintenance</li>
+
+	    <li>Exceptions handling</li>
+
+	    <li>Stack issues</li>
+	  </ul></li>
+
+	<li>ThunderX-specific changes and quirks</li>
+      </ul>
+
+      <p>This support was introduced to the public at the &os; 2015
+	Developer Summit in Ottawa at a demo held by Semihalf and the
+	&os; Foundation.  Cavium's ThunderX server CRB (Customer
+	Reference Board) is now capable of booting SMP &os; from both
+	the hard disk and from an NFS root using a PCIe networking
+	card.  The example setup is now available on the &os; test
+	cluster hosted at Sentex Communications.</p>
+
+      <p>ThunderX support changes are currently being reviewed and
+	integrated into mainline &os;.</p>
