PGPE: Multiple Droop Handling Fix

2020-02-18T21:14:10+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.

PGPE: Fix bad volt updt upon nack

2020-02-18T21:13:49+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.
