Sunny Wang 8e6bb64fe4 EmbeddedPkg/VirtualRealTimeClockLib: Fix SetTime issues ... This patch fixes two issues below: 1. SCT SetTime_Func failures. - https://github.com/pftf/RPi4/issues/164 2. Using shell time and date commands to set time can't work. The problem is that gRT->SetTime always returns EFI_INVALID_PARAMETER error status. The root cause is that LibSetTime() sets RtcEpochSeconds variable with inconsistent attributes. One is without EFI_VARIABLE_NON_VOLATILE, the other one is with EFI_VARIABLE_NON_VOLATILE. That caused that the variable driver returns EFI_INVALID_PARAMETER. Per UEFI spec, if a preexisting variable is rewritten with different attributes, SetVariable() shall not modify the variable and shall return EFI_INVALID_PARAMETER. Therefore, the solution is to add EFI_VARIABLE_NON_VOLATILE attribute to the first EfiSetVariable() call to make two calls consistent. By the way, this patch also fix a minor issue with a debug message.
