ThunderX (ARMv8)</url>
</links>
<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>
