Hi,
I don't normally monitor or contribute to oprofile so I'm not sure
what your patch conventions are. If this email or patch is not in the
correct format please let me know what that format is and I'll resubmit.
Notes:
- This patch applies to oprofile-0.9.1.tar.gz
- Vitaly Wool contributed significantly to this patch.
Thanks,
Mark

This patch adds PowerPC MPC7450 support to the oprofile tools.
In reality, it also adds support for the MPC7445, MPC7447, MPC7447A,
MPC7448, MPC7455, and MPC7457 processors but has only been tested
on a MPC7447A. The 7450 name was chosen because it matches the name
used in the Linux kernel, <file:arch/powerpc/oprofile/op_model_7450.c>.
Note that not all of the performance counters available on those
processors were added to the events file but its a start, at least.
