<p>skiboot-5.6.0-rc1 was released on Tuesday May 16th 2017. It is the first
release candidate of skiboot 5.6, which will become the new stable release
of skiboot following the 5.5 release, first released April 7th 2017.</p>
<p>skiboot-5.6.0-rc1 contains all bug fixes as of <a class="reference internal" href="skiboot-5.4.4.html#skiboot-5-4-4"><span class="std std-ref">skiboot-5.4.4</span></a>
and <a class="reference internal" href="skiboot-5.1.19.html#skiboot-5-1-19"><span class="std std-ref">skiboot-5.1.19</span></a> (the currently maintained stable releases). We
do not currently expect to do any 5.5.x stable releases.</p>
<p>For how the skiboot stable releases work, see <a class="reference internal" href="../process/stable-skiboot-rules.html#stable-rules"><span class="std std-ref">Skiboot stable tree rules and releases</span></a> for details.</p>
<p>The current plan is to cut the final 5.6.0 by May 22nd, with skiboot 5.6.0
being for all POWER8 and POWER9 platforms in op-build v1.17 (Due May 24th).
This is a short cycle as this release is mainly targetted towards POWER9
bringup efforts.</p>
<p>This is the first release using the new regular six week release cycle,
similar to op-build, but slightly offset to allow for a short stabilisation
period. Expected release dates and contents are tracked using GitHub milestone
and issues: <a class="reference external" href="https://github.com/open-power/skiboot/milestones">https://github.com/open-power/skiboot/milestones</a></p>
<p>Over skiboot-5.5, we have the following changes:</p>
<section id="new-platforms">
<h2>New Platforms<a class="headerlink" href="#new-platforms" title="Permalink to this headline">¶</a></h2>
<p>Thanks to SuperMicro for submitting support for the p9dsu platform, AKA Boston.</p>
</section>
<section id="power9">
<h2>POWER9<a class="headerlink" href="#power9" title="Permalink to this headline">¶</a></h2>
<p>XIVE:</p>
<blockquote>
<div><ul>
<li><p>xive: Clear emulation mode queue on reset</p></li>
<li><p>xive: Fixes/improvements to xive reset for multi-chip systems</p></li>
<li><p>xive: Synchronize after disable IRQs in opal_xive_reset()</p></li>
<li><p>xive: Workaround a problem with indirect TM access</p></li>
<li><p>hdata: Make FSPv1 work again
One less thing to work around for those crazy enough to try.</p></li>
<li><p>xive: Log more information in opal_xive_dump() for emulation state</p>
<p>Add a counter of total interrupts taken by a CPU, dump the
queue buffer both before and after the current pointer,
and also display the HW state of the queue descriptor and
the PQ state of the IPI.</p>
</li>
<li><p>xive: Add a per-cpu logging mechanism to XICS emulation</p>
<p>This is a small 32-entries rolling buffer that logs a few
operations. It’s useful to debug odd problems. The output
is printed when opal_xive_dump() is called.</p>
</li>
<li><p>xive: Check queues for duplicates in DEBUG builds.</p>
<p>There should never be duplicate interrupts in a queue.
This adds code to check that when looking at the queue
content. Since it can be a performance loss, this is only
done for debug builds.</p>
</li>
<li><p>xive+phb4: Fix exposing trigger page to Linux</p></li>
</ul>
</div></blockquote>
<p>HDAT Parsing:</p>
<blockquote>
<div><ul>
<li><p>hdata/spira.c: Add device-tree bindings for nest mmu</p></li>
<li><p>hdata/i2c: Workaround broken i2c devices</p></li>
<li><p>hdata: indicate when booted with elevated risk level</p>
<p>When the system is IPLed with an elevated risk level Hostboot will
set a flag in the IPL parameters structure. Parse and export this
in the device tree at: /ipl-params/sys-params/elevated-risk-level</p>
</li>
<li><p>hdata: Respect OCC and HOMER resevations</p>
<p>In the past we’ve ignored these since Hostboot insisted in exporting
broken reservations and the OCC was not being used yet. This situation
seems to have resolved itself so we should respect the reservations that
hostboot provides.</p>
</li>
</ul>
</div></blockquote>
<p>I2C:</p>
<ul>
<li><p>i2c: Add interrupts support on P9</p>
<p>Some older revisions of hostboot populate the host i2c device fields
with all zero entires. Detect and ignore these so we don’t crash on
boot.</p>
<p>Without this we get:</p>

<p>PHB4:</p>
<blockquote>
<div><ul>
<li><p>phb4: Enforce root complex config space size of 2048</p>
<p>The root complex config space size on PHB4 is 2048. This patch sets
that size and enforces it when trying to read/write the config space
in the root complex.</p>
<p>Without this someone reading the config space via /sysfs in linux will
cause an EEH on the PHB.</p>
<p>If too high, reads returns 1s and writes are silently dropped.</p>
</li>
<li><p>phb4: Add an option for disabling EEH MMIO in nvram</p>
<p>Having the option to disable EEH for MMIO without rebuilding skiboot
could be useful for testing, so check for pci-eeh-mmio=disabled in nvram.</p>
<p>This is not designed to be a supported option or configuration, just
an option that’s useful in bringup and development of POWER9 systems.</p>
</li>
<li><p>phb4: Fix slot presence detect</p>
<p>This has the nice side effect of improving boot times since we no
longer waste time tring to train links that don’t have anything
present.</p>

<p>OCC:</p>
<blockquote>
<div><ul>
<li><p>occ/irq: Fix SCOM address and irq reasons for P9 OCC</p>
<p>This patch fixes the SCOM address for OCC_MISC register which is used
for OCC interupts. In P9, OCC sends an interrupt to notify change in
the shared memory like throttle status. This patch handles this
interrupt reason.</p>
</li>

<p>NPU2:</p>
<blockquote>
<div><ul>
<li><p>npu2: Do not attempt to initialise non DD1 hardware</p>
<p>There are significant changes to hardware register addresses and
meanings on newer chip revisions making them unlikely to work
correctly with the existing code. Better to fail clearly and early.</p>
</li>
<li><p>npu, npu2: Describe diag data size in device tree</p></li>
</ul>
</div></blockquote>
<p>Memory Reservation:</p>
<blockquote>
<div><ul>
<li><p>mem_region: Add reserved regions after memory init</p>
<p>When a new memory region is added (e.g for memory reserved by firmware)
the list of existing memory regions is iterated through and a cut-out is
made in any existing region that overlaps with the new one. Prior to the
HDAT reservations being made the region init process was always:</p>
<blockquote>
<div><ol class="arabic simple">
<li><p>Create regions from the memory@<addr> DT nodes. (mostly large)</p></li>
<li><p>Create reserved regions from the device-tree. (mostly small)</p></li>
</ol>
</div></blockquote>
<p>When adding new regions we have assumed that the new region will only
every intersect with at most one existing region, which it will split.
Adding reservations inside the HDAT parser breaks this because when
adding the memory@<addr> node regions we can potentially overlap with
multiple reserved regions. This patch fixes this by maintaining a
seperate list of memory reservations and delaying merging them until
after the normal memory init has finished, similar to how DT
reservations are handled.</p>
</li>
</ul>

<li><p>pci: Describe PHB diag data size in device tree</p>
<p>Linux hardcodes the PHB diag data buffer at (as of this commit) 8192 bytes.
This has been enough for P7IOC and PHB3, but the 512 PEs of PHB4 pushes
the diag data blob over this size. Rather than just increasing the
hardcoded size in Linux, provide the size of the diag data blob in the
device tree so that the OS can dynamically allocate as much as it needs.
This both enables more space for PHB4 and less wasted memory for P7IOC
and PHB3.</p>
<p>P7IOC communicates both hub and PHB data using this buffer, so when
setting the size, use whichever struct is largest.</p>

<li><p>FSP: Notify FSP of Platform Log ID after Host Initiated Reset Reload</p>
<p>Trigging a Host Initiated Reset (when the host detects the FSP has gone
out to lunch and should be rebooted), would cause “Unknown Command” messages
to appear in the OPAL log.</p>
<p>This patch implements those messages</p>
<p>How to trigger FSP RR(HIR):</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ putmemproc 300000f8 0x00000000deadbeef

<p>The message we need to handle is “Get PLID after host initiated FipS
reset/reload”. When the FSP comes back from HIR, it asks “hey, so, which
error log explains why you rebooted me?”. So, we tell it.</p>

There’s a few places where we don’t match the regex. Fix them, as it’s
harmless to do so.</p>

<p>We recently made MTD 64 bit safe in e5720d3fe94 which now requires the
64 bit MTD erase ioctl. Unfortunately this ioctl is not present in
older kernels used by some BMC vendors that use pflash.</p>
<p>This patch addresses this by only using the 64bit version of the erase
ioctl() if the parameters exceed 32bit in size.</p>
<p>If an erase requires the 64bit ioctl() on a kernel which does not
support it, the code will still attempt it. There is no way of knowing
beforehand if the kernel supports it. The ioctl() will fail and an error
will be returned from from the function.</p>
