| skiboot-5.9-rc4 |
| =============== |
| |
| skiboot v5.9-rc4 was released on Thursday October 19th 2017. 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. |
