Programmable Registers
Address:
Re-
19.4.57 Default First-Level Page Table Movable PTE Locator 7
This register is used by the DFLPT to set the location for MPTE7.
When using the hardware-based Default First-Level Page Table (DFLPT), program this
value to set the location for Movable PTE (MPTE7) to any of the 4096 sections.

Setting this bit to 1 disables the MPTE. A disabled MPTE cannot be bound to the page table and cannot be
modified.
Reserved.
This bit-field allows this PTE to span a larger than 1MB section of memory. Specifically 1MB * (2^SPAN).
Care must be taken to make sure that spanned regions do not overlap in the page table, since the DFLPT
does not provide any correction mechanism in an overlapped scenario. Because only one value can be set
for the MPTE base-address section entry, the DFLPT assumes linear physical 1 MB addressing within a
SPAN. For example, assuming a value N for LOC and SPAN=2, the DFLPT assumes the value of LOC,
LOC+1, LOC+2 and LOC+3 for the four values within that span; that is, all base addresses within a span
are contiguous.
Reserved.
Value of LOC corresponds to 1MB section number (0x000-0xFFF) within the DFLPT.Note that when the
SPAN field is used, any MPTE can cover up to 128MB. Do not program to 0x800 (fixed PIO entry). No two
HW_DIGCTL_MPTEn_LOC registers can have the same value, and care must be taken to not create overlap
when using the SPAN feature. Doing so will result in non-deterministic behavior of the DFLPT.
