It replaces +:ref:`skiboot-5.10.1` as the current stable release in the 5.10.x series. + +Over :ref:`skiboot-5.10.1`, we have one improvement: + +- Tie tm-suspend fw-feature and opal_reinit_cpus() together + + Currently opal_reinit_cpus(OPAL_REINIT_CPUS_TM_SUSPEND_DISABLED) + always returns OPAL_UNSUPPORTED. + + 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. + + 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). + + 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. |
