<p>skiboot 6.3.3 was released on Wednesday Aug 6th, 2019. It replaces
<a class="reference internal" href="skiboot-6.3.2.html#skiboot-6-3-2"><span class="std std-ref">skiboot-6.3.2</span></a> as the current stable release in the 6.3.x series.</p>
<p>It is recommended that 6.3.3 be used instead of any previous 6.3.x version
due to the bug fixes it contains.</p>
<p>Bug fixes included in this release are:</p>
<ul>
<li><p>struct p9_sbe_msg doesn’t need to be packed</p>
<p>Only the reg member is sent anywhere (via xscom_write), so the structure
does not need to be packed.</p>
</li>
</ul>
<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>Fixes GCC9 build problem:

<li><p>Support BMC IPMI heartbeat command</p>
<p>A few years ago, the OpenBMC code added support for a “heartbeat”
command to send to the host. This command is used after the BMC is reset
to check if the host is running. Support was never added to the host
side however so currently when the BMC sends this command, this appears
in the host console:
IPMI: unknown OEM SEL command ff received</p>
<p>There is no response needed by the host (other then the low level
acknowledge of the command which already occurs). This commit
handles the command so the error is no longer printed (does nothing with
the command though since no action is needed). Here’s the tested output
of this patch in the host console (with debug enabled):
IPMI: BMC issued heartbeat command: 00</p>
</li>
<li><p>Add: add mihawk platform file</p></li>
</ul>
