----BIOS\edk2-platforms\Vlv2TbltDevicePkg\PlatformSmm\Platform.c // // Set Hour // IoWrite8(PCAT_RTC_ADDRESS_REGISTER, RTC_ADDRESS_HOUR_ALARM); for(i = 0 ; i < 0xffff ; i++){ IoWrite8(PCAT_RTC_DATA_REGISTER, mWakeupHour); SmmStall(1); if(IoRead8(PCAT_RTC_DATA_REGISTER) == mWakeupHour){ break; } }

if (!mSystemConfiguration.WakeOnRtcS5) { return; } mWakeupDay = HexToBcd((UINT8)mSystemConfiguration.RTCWakeupDate); mWakeupHour = HexToBcd((UINT8)mSystemConfiguration.RTCWakeupTimeHour); mWakeupMinute = HexToBcd((UINT8)mSystemConfiguration.RTCWakeupTimeMinute); mWakeupSecond = HexToBcd((UINT8)mSystemConfiguration.RTCWakeupTimeSecond);
