If you do.... I went to do what I thought was a basic fix up to the kernel builds on POWER to get rid of the last bits of the ppc32 legacy, on my list for some time, and it has become more of a slightly epic slash and burn!
The resulting output kernel configs are for all intents and purpose unchanged but the git diff is some what epic.
The top level of the changes are:
Core changes that apply too all kernels (ppc64/ppc64p7/ppc64le) reside in config-powerpc64-generic
config-powerpc64 ->> legacy platforms that are older than POWER7 and
their dependencies (here lies the ghosts of PowerPC G5 and friends).
config-powerpc64le and config-powerpc64p7 contain anything specific to POWER7 and newer that might affect older platforms, or LE/BE specific to p7 and later
I saw a recent post by Peter Saisanas on the debian powerPC list that warns that the nouveau video driver is not compatible with 64KB pages.
https://lists.debian.org/debian-powerpc/2015/06/msg00054.html
If you plan to set up the config-powerpc64le and config-powerpc64p7 with 64K pages, please leave config-powerpc64 as 4KB.
One has about an equal chance of encountering ATI and Vidia graphics on Mac PPC64 machines. I know nothing about the recent P8 boxes.
