The Linux/PPC kernel supports PEEK/POKE for fetching registers. The
proposed Kernel interface _consistently_ extends that interface using
the exact same mechanims to obtain the altivec regiters. All the
required changes for this have been posted and have been demonstrated to
work.
Separate to that, it has been _proposed_ that the PPC ptrace() interface
be changed so that get/set reg for all register classes be added
(incomplete patch posted). Isn't this separate to the problem at hand?
If we are going to add a get/set reg interface for the altivec vector
registers, I would rather not extend the peek/poke interface to do
that as well.
