Release Notes for OpenPower Firmware v1.21-rc2
==============================================

Please note that this is a RELEASE CANDIDATE and not the final v1.21
release. We expect to do a final v1.21 tagged release in the week of the
19th Feb.

This release (including the final v1.21) is NOT intended for GA POWER9
platforms.

Known Issues
------------

There are also known issues with deeper stop states and special wakeup
(used when collecting some sensors on stopped cores). We have included a
work-around in v1.21-rc2 where stop11 is disabled for witherspoon. This
won't affect runtime power savings as stop11 is only used by Linux for
CPU hotplug. We will re-enable it in the future once we've isolated the
problem.

v1.21-rc1 known issues that are now fixed
-----------------------------------------

The issues with some POWER9 platforms with NVLink and specific
kernels/GPU drivers are now fixed.

The issue with skiboot on ZZ systems with latest FSP firmware builds has
been fixed, ZZ with secure boot disabled should now boot again.
