Fix for missing HBRT error log after error injected

2020-01-15T14:42:51+00:00

An HBRT error log larger than 4K sent to the host will be truncated to 4K before it reaches HWSV, where a size mismatch prevents processing of the log. To avoid this, truncate the HBRT log to 4K before sending across interface to host.

Compile Hostboot with -Os

2019-10-03T15:55:14+00:00

Hostboot currently spends a significant percentage of time loading data from PNOR across a relatively slow LPC bus. This commit enables compilation of Hostboot with -Os, optimized for space to reduce the amount of data required to be transferred across the LPC bus Rough measurements show a ~30% size reduction of the hostboot image and a ~10% reduction (improvement) in boot time Change-Id: Ib73863019595a24cc7d10e924bc5c92cd64af1ed Reviewed-on: http://rchgit01.rchland.ibm.com/gerrit1/84436 Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Tested-by: Jenkins OP HW Tested-by: FSP CI Jenkins Reviewed-by: William G Hoffa

Revert "Compile Hostboot with -Os"

This reverts commit cd1e5c91e4a15ca933c699553ece9b841825ac03. The previous change seems to be causing problems with thread local storage (TLS) access.

Increment HBRT EID on every commit

2018-09-28T13:28:28+00:00

When HBRT first boots we read ATTR_HOSTSVC_PLID to set our starting PLID/EID number. However, we never increment that attribute as we create new logs. This will result in HBRT reusing PLIDs if it ever reboots (e.g. after a crash or as part of a code update) and also when it restarts after a mpipl.

Deconfig EC/EX/EQ at runtime

2018-08-30T16:00:31+00:00

Applied the normal parent/child rules for EC/EX/EQ logic to be done in the runtime deconfig logic. After applying the deconfig logic, then reset the PM for the parent proc of the EX/EX/EQ. To facilitate the code changes, modified the return value of the TARGETING::getParent(...) call. It no longer returns a const * Target, considering 5 times out of 7 of it's usage, users were just staic_cast(ing) away the const. Clear out the HB reset attribute in the mpipl path. Modify PRD logic to use runtime deconfig call in malfunction alert path.

Allow HWSV to handle gard callouts during runtime for FSP systems

2018-06-29T02:53:11+00:00

There was a bug in the runtime code where if a errorlog was created and it had a deconfigure callout as well as a gard callout it would attempt to create a gard record for the callout. This caused PNOR reads which are not permitted in HBRT on systems with FSPs.

Add deconfigTargetAtRuntime interface

2018-04-12T20:31:07+00:00

-PRD will call this function in response to a core unit checkstop detected by PHYP. The new function will mark the core as non-functional and call a hardware procdure to update the multicast groups for cores and chiplets. The procedure will also update the OCC core configuration status and the quad core status registers which reflect the number of enable cores/quad in the system at runtime.

Initialize FIRDATA section and ErrlManager just incase BMC resets

2018-03-07T17:54:24+00:00

PRD needs to read the PNOR to tell OCC where to write in the pnor. This will cache the PNOR section so PRD will not fail the read call. If an error is created with pnor inaccessible, errl manager could get stuck unless it was initialized first.
