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.

Close race condition in multi instance IPC

2018-02-16T15:02:29+00:00

P9 Doorbells operate differently than P8 IPI mechanism, creating a race condition. Basically because the HB kernel turns a doorbell into a message, and then is ready for another one -- it can lose the next one since repeated messages with same key are dropped (IPC handling clears memory comm area, other HB instances notice, fill and drop a doorbell before getting back into kernel) Change-Id: I8eb6f010600afb9de365c8942fcd24227903436f Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/54118 Reviewed-by: Prachi Gupta Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Tested-by: Jenkins OP HW Tested-by: FSP CI Jenkins Reviewed-by: William G.

Multi-Drawer (IPC) Interrupt/Messaging Support

2018-01-25T22:44:20+00:00

- Use doorbells instead of IPIs (no IPI support using LSI interupts in the XIVE intr architecture) - New message type from kernel to userspace so the kernel can notify the HB userspace Interrupt Resource Provider (INTRP) that an IPC message was sent to the particular HB instance (in P8 this happened automatically as that was part of the IPI architecture). - Re-enable testcase that validates that an IPC message can be successfully sent.

Expand Hostboot to 64MB

2018-01-16T03:36:51+00:00

We hit out-of-memory errors while trying to boot a Opal system due to the large amount of memory used by the PM procedures and the pinning of memory in secure mode. Also did some other rearranging of the pinned memory sections to get some space back.

Ensure AbaPtr is not used in runtime code

2017-10-20T02:17:12+00:00

The AbaPtr makes assumptions that we have pointer values that are only 32-bits long. In our runtime (HBRT) environment that assumption is not true so we need to make sure none of the code that runs there is trying to use the AbaPtr code.
