When accessing TAD interface via sysfs, like setting/getting realtime, it also causes errors: [ 478.255453] ACPI Error: No handler for Region [RTCM] (00000000a8d2dd39) [SystemCMOS] (20230331/evregion-130) [ 478.255458] ACPI Error: Region SystemCMOS (ID=5) has no handler (20230331/exfldio-261) [ 478.255461] Initialized Local Variables for Method [_GRT]: [ 478.255461] Local1: 00000000f182542c <Obj> Integer 0000000000000000 [ 478.255464] No Arguments are initialized for method [_GRT] [ 478.255465] ACPI Error: Aborting method \_SB.AWAC._GRT due to previous error (AE_NOT_EXIST) (20230331/psparse-529) [Fix] Let the driver to install a handler for its SystemCMOS region. The spec on whether certain devices can use SystemCMOS or not is quite vague, so follow the de facto implementation, Windows :) [Test] Once the patch is applied, setting and getting realtime through TAD sysfs work, and there's no more error in dmesg. [Where problems could occur] Now ACPI TAD driver also depends on ACPI RTC driver, so the memory usage will go up slightly.
