Move definition of TRACE_ERR_FMT and TRACE_ERR_ARGS

2020-02-03T15:22:01+00:00

Originally TRACE_ERR_FMT and TRACE_ERR_ARGS were defined in centaurScomCache.H for the P9 'master' branch. This commit puts them into the more proper errlentry.H file like they are for P10's 'master-p10' branch.

Forcibly clear all previous wakeups when the PM Complex starts

2018-09-19T14:50:03+00:00

The power management logic was designed with the assumption that the external callers would manage the state machine such that the order of operations is always: load->start->reset->load->start->reset->etc. However, we have discovered edge cases where a reset can happen before the first load or after a previous reset. In either case we will end up with our wakeup counter being off by one and thus never releasing wakeup. The solution is to add logic to the start path that will explicitly clear the counter out completely, regardless of its current value. This will ensure that wakeup is released once the complex is alive.

Check capability bit before using wakeup for OPAL in OpenPOWER

2018-09-05T12:56:44+00:00

A recent change switched out special wakeup handling over to use the host interface instead of the internal HWP calls. However, we just discovered that the opal-prd application was not allowing those calls on non-FSP systems. The opal-prd code is being updated, but since that is delivered as part of the Linux distro (not firmware) we need to handle the situation where newer Hostboot is running on top of the older opal-prd. This commit adds a check for a new OPAL-specific capability bit that will ensure we only use the wakeup interface if the opal-prd hosting us supports it.

Centaur Channel Checkstop (runtime)

2018-06-05T18:00:46+00:00

This story covers when a DMI channel gets checkstopped at runtime and how to service the subsequent SCOM operations that PRD requests to diagnose the issue. At runtime, PRD makes all of its SCOM requests to HBRT which passes them on to PHYP for in-band access. The checkstop blocks in-band access, so HBRT must fail-over to messaging the FSP to do FSI accesses. To reduce the number of SCOM calls to the FSP, HBRT makes a "multi-SCOM read" call for all the common SCOMs that PRD will request after a checkstop, and caches the results. Two new calls (MBOX, generic messaging interface) to the FSP were added in a previous commit to allow FSI SCOM operations through the FSP: - MSG_SINGLE_SCOM_OP - MSG_MULTI_SCOM_OP Also, a new map, chnlFailScomList, was added in a previous commit. chnlFailScomList contains a list of target types and associated SCOM addresses that PRD is likely want to read after a checkstop. PRD is responsible for maintaining the contents.

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.
