============
CPU Families
============

This document tries to summarise some of the different cpu families that exist
and are supported by arch/powerpc.


Book3S (aka sPAPR)
------------------

- Hash MMU (except 603 and e300)
- Radix MMU (POWER9 and later)
- Software loaded TLB (603 and e300)
- Selectable Software loaded TLB in addition to hash MMU (755, 7450, e600)
- Mix of 32 & 64 bit::
