Michael Kubacki 6f9838f32f MdeModulePkg/Variable: Add RT GetNextVariableName() cache support ... https://bugzilla.tianocore.org/show_bug.cgi?id=2220 This change implements the Runtime Service GetNextVariableName() using the runtime cache in VariableSmmRuntimeDxe. Runtime Service calls to GetNextVariableName() will no longer trigger a SW SMI when gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache is set to TRUE (default value). Overall system performance and stability will be improved by eliminating an SMI for these calls as they typically result in a relatively large number of invocations to retrieve all variable names in all variable stores present.
