Subject: ppc_htab.c and ppc7447A performance monitor registers

Hi all,

( referring to kernel source as of 2.6.11 )

Among other things, Cort Dougan has provided support for usage of the
performance counters in 604 type cores via: /proc/ppc_htab.
This is great, but the required cpu feature: CPU_FTR_604_PERF_MON is not in
the list for the 7447 ppc family.

I guess there are differences related to the performance counter registers
and the monitor control registers between the the 604 core types and 7447,
but I haven't had time to research it.

I was wondering if anyone has upgraded:  cputable.c and ppc_htab.c for use
with ppc types, other than 604, that have performance monitor registers and
if such code is publically available?

regards, Ron
