<h1>skiboot-5.1.3<a class="headerlink" href="#skiboot-5-1-3" title="Permalink to this headline">¶</a></h1>
<p>skiboot-5.1.3 was released on September 15th, 2015.</p>
<p>skiboot-5.1.3 is the 4th stable release of 5.1, it follows skiboot-5.1.2
(which was released September 9th, 2015).</p>
<p>Skiboot 5.1.3 contains all fixes from skiboot-5.1.2 and is a minor bugfix
release.</p>
<section id="changes">
<h2>Changes<a class="headerlink" href="#changes" title="Permalink to this headline">¶</a></h2>
<p>Over skiboot-5.1.2, we have the following changes:</p>
<ul>
<li><p>slot names for firestone platform</p></li>
<li><p>fix display of LPC errors</p></li>
<li><p>SBE based timer support</p>
<ul class="simple">
<li><p>on supported platforms limits reliance on Linux heartbeat</p></li>
</ul>
</li>
<li><p>fix use-after-free in fsp/ipmi</p></li>
<li><p>fix hang on TOD/TB errors (time-of-day/timebase) on OpenPower systems</p>
<ul class="simple">
<li><p>On getting a Hypervizor Maintenance Interrupt to get the timebase
back into a running state, we would call prlog which would use
the LPC UART console driver on OpenPower systems, which depends on
a working timebase, leading to a hang.
We now don’t depend on a working timebase in this recovery codepath.</p></li>
</ul>
</li>
<li><p>enable prd for garrison platform</p></li>
<li><p>PCI: Clear error bits after changing MPS
Chaning MPS on PCI upstream bridge might cause error bits set on
downstream endpoints when system boots into Linux as below case
shows:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">host</span><span class="c1"># lspci -vvs 0001:06:00.0</span>

<span class="n">DevSta</span><span class="p">:</span> <span class="n">CorrErr</span><span class="o">+</span> <span class="n">UncorrErr</span><span class="o">-</span> <span class="n">FatalErr</span><span class="o">-</span> <span class="n">UnsuppReq</span><span class="o">+</span> <span class="n">AuxPwr</span><span class="o">-</span> <span class="n">TransPend</span><span class="o">-</span>
<span class="n">CESta</span><span class="p">:</span> <span class="n">RxErr</span><span class="o">-</span> <span class="n">BadTLP</span><span class="o">-</span> <span class="n">BadDLLP</span><span class="o">-</span> <span class="n">Rollover</span><span class="o">-</span> <span class="n">Timeout</span><span class="o">-</span> <span class="n">NonFatalErr</span><span class="o">+</span>
</pre></div>
</div>
<p>This clears those error bits in AER and PCIe capability after MPS
is changed. With the patch applied, no more error bits are seen.</p>
