From 025a95b7edfbb6ca11356ab87a300db443bd105b Mon Sep 17 00:00:00 2001 From: Dun Tan Date: Wed, 10 Apr 2024 11:27:51 +0800 Subject: MdeModulePkg:Add new gEdkiiVariableRuntimeCacheInfoHobGuid This commit defines VARIABLE_RUNTIME_CACHE_INFO HOB. The HOB is used to store the address and size of the buffer that will be used for variable runtime service when the PcdEnableVariableRuntimeCache is TRUE. In following patches, when PcdEnableVariableRuntimeCache is TRUE, VariablePei module will install a callback of gEfiPeiMemoryDiscoveredPpiGuid to allocate needed buffer for different type cache, unblock the buffer and build HOB. Then VariableSmmRuntimeDxe driver will consume the gEdkiiVariableRuntimeCacheInfoHobGuid to initialize the variable runtime cache related content.
