| <p>skiboot 5.10.2 was released on Tuesday March 6th, 2018. It replaces |
| <a class="reference internal" href="skiboot-5.10.1.html#skiboot-5-10-1"><span class="std std-ref">skiboot-5.10.1</span></a> as the current stable release in the 5.10.x series.</p> |
| <p>Over <a class="reference internal" href="skiboot-5.10.1.html#skiboot-5-10-1"><span class="std std-ref">skiboot-5.10.1</span></a>, we have one improvement:</p> |
| <ul> |
| <li><p>Tie tm-suspend fw-feature and opal_reinit_cpus() together</p> |
| <p>Currently opal_reinit_cpus(OPAL_REINIT_CPUS_TM_SUSPEND_DISABLED) |
| always returns OPAL_UNSUPPORTED.</p> |
| <p>This ties the tm suspend fw-feature to the |
| opal_reinit_cpus(OPAL_REINIT_CPUS_TM_SUSPEND_DISABLED) so that when tm |
| suspend is disabled, we correctly report it to the kernel. For |
| backwards compatibility, it’s assumed tm suspend is available if the |
| fw-feature is not present.</p> |
| <p>Currently hostboot will clear fw-feature(TM_SUSPEND_ENABLED) on P9N |
| DD2.1. P9N DD2.2 will set fw-feature(TM_SUSPEND_ENABLED). DD2.0 and |
| below has TM disabled completely (not just suspend).</p> |
| <p>We are using opal_reinit_cpus() to determine this setting (rather than |
| the device tree/HDAT) as some future firmware may let us change this |
| dynamically after boot. That is not the case currently though.</p> |
