Secure Boot: Implement Centaur SCOM cache

2018-05-08T13:44:28+00:00

This change implements a Centaur SCOM cache for sensitive SCOM registers. The cache is initialized and enabled before the first Centaur SCOM, and disabled just prior to locking down the Centaur configuration. Once the Centaur has been locked down, the real register values are compared to the cache entries, and the Centaur is deconfigured (not garded) on any mismatch in assumptions.

Enable platSpecialWakeup during IPL time and add support

2018-02-17T21:26:17+00:00

Previously we only supported platSpecialWakeup at runtime because we were not worried about needed special wakeup as the cores would not go into stop state during the IPL. However, now PM code is expecting bits to be set by the p9 special wakeup hwp so we need to call it during the IPL. This code makes the handleSpecialWakeup.C/H files compatible with IPL time build environment and enables the call on the IPL time path CQ: SW415949 Change-Id: I94cca8a84946bea464b21cb95cdbbb075f766c3d Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/52858 Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Tested-by: Jenkins OP HW Reviewed-by: Christian R.

Tweaks to multicast scom workaround

2018-01-09T15:37:55+00:00

Added a mode to avoid a pile of FFDC collection for the case where we expect errors could happen. Also added a couple new flags to control which chiplets get accessed as part of the workaround, one to avoid access to slave cores before they are running and the other to avoid access to the memory chiplets before they have clocks enabled. Without these changes, the code is still functionally correct but the traces get filled with pointless non-errors which makes real problems harder to find and also increases boot time.
