What is the exact meaning of EPTP with Extended Page Tables?

Juergen asked:

EPT stands for Intel Extended Page Tables.
But what does the suffix P stand for in the term EPTP switching ?

If there is a reliable source, I would like to add the answer to the Second Level Address Translation Wikipedia article.

My answer:


Intel made it up. It stands for Extended Page Table Pointer, and it is a table which (as the name suggests) points into the extended page table. See Intel® 64 and IA-32 Architectures Software Developer’s Manual Volume 3C: System Programming Guide, Part 3, section 24.6.11 for a full description of the EPTP and the EPT table to which it points.
