.. _skiboot-5.10.2:
==============
skiboot-5.10.2
==============
skiboot 5.10.2 was released on Tuesday March 6th, 2018. 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.
