If enabled, SMM will not use on-demand paging. SMM will build static page table for all memory. The page table size depend on 2 things: 1) The 1G paging capability. 2) The whole system memory/MMIO addressing capability. A) If the system only supports 2M paging, When the whole memory/MMIO is 32bit, we only need 1+1+4=6 pages for 4G. When the whole memory/MMIO is 39bit, we need 1+1+256 pages (~ 1M) When the whole memory/MMIO is 48bit, we need 1+256+256*256 pages (~ 257M) B) If the system supports 1G paging. When the whole memory/MMIO is 32bit, we only need 1+1+4=6 pages for 4G. (We still generate 2M page for maintenance consideration.) When the whole memory/MMIO is 39bit, we still need 6 pages. (We setup 1G paging for >1G.) When the whole memory/MMIO is 48bit, we need 1+256 pages (~ 1M).
