This changes the way that we support the new ISA v3.00 HPTE format. Instead of adapting everything that uses HPTE values to handle either the old format or the new format, depending on which CPU we are on, we now convert explicitly between old and new formats if necessary in the low-level routines that actually access HPTEs in memory. This limits the amount of code that needs to know about the new format and makes the conversions explicit. This is OK because the old format contains all the information that is in the new format. This also fixes operation under a hypervisor, because the H_ENTER hypercall (and other hypercalls that deal with HPTEs) will continue to require the HPTE value to be supplied in the old format. At present the kernel will not boot in HPT mode on POWER9 under a hypervisor. This fixes and partially reverts commit |
