It is the fourth +release candidate of skiboot 5.9, which will become the new stable release +of skiboot following the 5.8 release, first released August 31st 2017. + +skiboot v5.9-rc4 contains all bug fixes as of :ref:`skiboot-5.4.8` +and :ref:`skiboot-5.1.21` (the currently maintained stable releases). We +do not currently expect to do any 5.8.x stable releases. + +For how the skiboot stable releases work, see :ref:`stable-rules` for details. + +The current plan is to cut the final 5.9 by October 20th, with skiboot 5.9 +being for all POWER8 and POWER9 platforms in op-build v1.20 (Due October 18th, +so we're running a bit behind there). +This release will be targetted to early POWER9 systems. + +Over :ref:`skiboot-5.9-rc3`, we have the following changes: + +- phb4: Fix PCIe GEN4 on DD2.1 and above + + In this change: + eef0e197ab PHB4: Default to PCIe GEN3 on POWER9 DD2.00 + + We clamped DD2.00 parts to GEN3 but unfortunately this change also + applies to DD2.1 and above. + + This fixes this to only apply to DD2.00. +- occ-sensors : Add OCC inband sensor region to exports + (useful for debugging) + +Two SRESET fixes: + +- core: direct-controls: Fix clearing of special wakeup + + 'special_wakeup_count' is incremented on successfully asserting + special wakeup. So we will never clear the special wakeup if we + check 'special_wakeup_count' to be zero. Fix this issue by checking + the 'special_wakeup_count' to 1 in dctl_clear_special_wakeup(). +- core/direct-controls: increase special wakeup timeout on POWER9 + + Some instances have been observed where the special wakeup assert + times out. The current timeout is too short for deeper sleep states. + Hostboot uses 100ms, so match that. |
