The wake-up events are generated when BIOS sets + ALL_MONITOR_OFF for power-saving on TGL systems. + + [Fix] + A BIOS workaround is used to skip ALL_MONITOR_OFF with an _OSI string + "Linux-Dell-USB4-Wakeup". + + [Test] + Verified on Dell's TigerLake platforms + + [Regression Potential] + Low. This only works on platforms supporting "Linux-Dell-USB4-Wakeup". + No other platforms will be affected.
