This buffer is used to store VOLATILE > attribute variables. There is no inherent reason why the size of the volatile variable store should match the same of the non-volatile variable store. Indeed flash variables in the 4MB build work fine without this equality. However, OvmfPkg/EmuVariableFvbRuntimeDxe uses PcdVariableStoreSize to initialize the non-volatile VARIABLE_STORE_HEADER too. (Presumably based on the fact that ultimately that storage will not be permanent.) When using EmuVariableFvbRuntimeDxe in the 4MB build, the mismatch between the two mentioned PCDs (which is apparent through EmuVariableFvbRuntimeDxe's VARIABLE_STORE_HEADER) triggers an assertion in the variable driver: > ASSERT MdeModulePkg/Universal/Variable/RuntimeDxe/Variable.c(3772): > mNvVariableCache->Size =3D=3D VariableStoreLength Bringing PcdVariableStoreSize in sync with PcdFlashNvStorageVariableSize fixes this. It also happens to ensure a volatile store size in the 4MB build that equals the non-volatile store size, which likely doesn't hurt for symmetry.
