hi,
In the windows10 environment, set the RTC_EN bit before entering S5 from S0 after pressing the power button to turn on the RTC Wake up function.
At https://github.com/tianocore/e dk2-platforms/blob/bb44e786e7a 7cc618e985b3e0b93a9f33a4b7ea2/ Platform/Intel/Vlv2TbltDeviceP kg/PlatformSmm/Platformcc ( https://github.com/tianocore/edk2-platforms/blob/bb44e786e7a7cc618e985b3e0b93a9f33a4b7ea2/Platform/Intel/Vlv2TbltDevicePkg/PlatformSmm/Platformcc ).
Registered power button event. Is this event automatically generated when the power button is pressed? Or does it need to write a value to port 0xb2 through ACPI's asl code to generate a SW SMI event?
Best Regards
Victor
