I recommend using the new EfiEventGroupSignal() function from UefiLib instead.

Please refer to the following commits:

ca8f50e88e03 MdePkg/UefiLib: move InternalEmptyFunction to UefiLib.c 772fb7cb13de MdePkg/UefiLib: introduce EfiEventGroupSignal
ff55dd3befb4 IntelFrameworkPkg/FrameworkUefiLib: move InternalEmptyFunction to UefiLib.c
6212b9481d82 IntelFrameworkPkg/FrameworkUefiLib: implement EfiEventGroupSignal dfc9514794fc ArmVirtPkg/PlatformIntelBdsLib: rebase to EfiEventGroupSignal 36e8e6992d0c OvmfPkg/PlatformBdsLib: rebase to EfiEventGroupSignal

Thanks
Laszlo
