Set HB Dump Flag in TI Data on any TI with SRC

2018-05-14T02:45:35+00:00

Rather than rely on HWSV code to recognize there is a TI with SRC, and so do a Hostboot dump, just always set the flag in the TI with SRC data that will request that HWSV to do the HB dump.

Implement Interrupt Resource Provider Init for MPIPL Multi-Node Systems

2018-05-07T20:18:19+00:00

- In MPIPL the HW interrupt config could be such that interrupts will cross node boundaries. HB handles interrupts independently on each node - so initialize INTRP in a way to handle this transition. - Modify the MPIPL flow with the following changes: a) Set the Interrupt LSI State Machine to disabled b) Enable LSI Mode via the Interrupt Control Register c) Force all nodes to sync after steps a + b - Enable INTRP Multi-Node MPIPL Sync Code developed in P8 - Each node will now initialize its own internode_info data area during an initial IPL - Coalescing of the Host will modify this data to define all the nodes in the system - During the MPIPL each node can view each others area to determine when all nodes have reached the common sync point - Remove Legacy P8 MPIPL INTRP Code that is not used Change-Id: Idb742eafc7389f328ea7f506c4c4541c989e52b6 RTC: 182712 Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/57993 Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Reviewed-by: Prachi Gupta Tested-by: Jenkins OP HW Reviewed-by: Christian R.

Better debug for weird PIR issues

2018-05-07T20:13:33+00:00

Ran into a case where Hostboot was getting booted with the wrong fabricid for the node it was on. In the process I realized it was hard to tell what was going on. Added printk output to show the PIR of the boot core. Modified how force-hrmor option is consumed in ecmd-debug-framework so that you can force unnatural lookups.

Get Hostboot Dump after Hostboot Crash

2018-04-09T20:38:00+00:00

When Hostboot has a TI with a PLID rather than a Reason Code (RC), HWSV does not attempt the Hostboot Dump. Thought is that happens per the design as the error log related to the PLID sent by Hostboot should already have the required information. There are instances where the error log does not have sufficient data and a dump would be beneficial. A path is being added so an error log can be flagged as needing a Hostboot dump.

Secure Boot: Support Phyp debug flag in HDAT

2018-04-09T20:29:14+00:00

PHYP needs a way to know if SBE security backdoor is enabled for debug purposes. This change creates a flag in TPM instance data structure to indicate whether the backdoor is enabled. This flag is passed by SBE to the hb bootloader; also added the flag to indicate whether PCR is poisoned (default of 0). The population of this flag will be implemented on Fleetwood.
