That means users cannot use it to change page attributes, and have to turn to CPU arch protocol to do it, which is not be allowed by PI spec. >From CpuDxe driver perspective, it doesn't update GCD memory attributes from current page table setup during its initialization. So the memory attributes in GCD might not reflect all memory attributes in real world.
