| <p>skiboot 5.9.9 was released on Monday May 28th, 2018. It replaces |
| <a class="reference internal" href="skiboot-5.9.8.html#skiboot-5-9-8"><span class="std std-ref">skiboot-5.9.8</span></a> as the current stable release in the 5.9.x series.</p> |
| <p>Over <a class="reference internal" href="skiboot-5.9.8.html#skiboot-5-9-8"><span class="std std-ref">skiboot-5.9.8</span></a>, we have two bug fixes and a build fix, they are:</p> |
| <ul> |
| <li><p>OPAL_PCI_SET_POWER_STATE: fix locking in error paths</p> |
| <p>Otherwise we could exit OPAL holding locks, potentially leading |
| to all sorts of problems later on.</p> |
| </li> |
| <li><p>lpc: Clear pending IRQs at boot</p> |
| <p>When we come in from hostboot the LPC master has the bus reset indicator |
| set. This error isn’t handled until the host kernel unmasks interrupts, |
| at which point we get the following suprious error:</p> |
| <div class="highlight-default notranslate"><div class="highlight"><pre><span></span>[ 20.053560375,3] LPC: Got LPC reset on chip 0x0 ! |
| [ 20.053564560,3] LPC[000]: Unknown LPC error Error address reg: 0x00000000 |
| </pre></div> |
| </div> |
| <p>Fix this by clearing the various error bits in the LPC status register |
| before we initalise the skiboot LPC bus driver.</p> |
| </li> |
| <li><p>stb: Build fixes in constructing secure and trusted boot header</p></li> |
| </ul> |
