PGPE: Multiple Droop Handling Fix

2019-09-17T07:12:30+00:00

Key_Cronus_Test=PM_REGRESS - Fixes droop handling issue where the second time prolonged droop condition is detected, PGPE doesn't attempt to throttle, set OCCFLG[PM_RESET_SUPPRESS] - Fixes handling of droop condition when PGPE attempts to actuate the system to Psafe. PGPE correctly sends re-trying DB3 Safe Mode msg instead of DB3 Replay DB0 msg. Also, CME correctly sets the CME_FLAGS[SAFE_MODE] bit only after system has actuated to Psafe rather than on first attempted move to Psafe.

CME: Reduce Image Size

2019-09-10T11:39:04+00:00

On some systems, the ring overrides size is more than anticipated, and causes a run time failure when CME Image is loaded during istep 15/16. Therefore, we are reducing CME Image Size by converting PK_TRACE_INF to PK_TRACE_DBG for some trace statements.

PGPE: Fix bad volt updt upon nack

2019-09-10T11:38:52+00:00

Key_Cronus_Test=PM_REGRESS As part of undervolting code, the nack handling was modified to remove any amount of undervolting. This is because undervolting can be the cause of the droop and hence the nack. However, the original code didn't properly account for the freq and voltage update ordering. As a result, sometimes voltage would be updated before frequency/vdm/resclk update in the wrong order, and resulting in droop forever.
