skiboot 5.10.2 was released on Tuesday March 6th, 2018. It replaces
skiboot-5.10.1 as the current stable release in the 5.10.x series.
Over skiboot-5.10.1, we have one improvement:
* Tie tm-suspend fw-feature and opal_reinit_cpus() together
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.
