Description Geoff Gustafson 2008-03-28 19:08:22 EDT
The Penryn-based CPUs have the same performance registers as older Core 2 chips,
but they have a new model number (23 instead of 15).

I suspect the same one-line patch from 5.2 is needed to oprofile code so
oprofile will treat them the same way.

I will test this out on Monday and post the patch.
Comment 1 Ronald Pacheco 2008-03-30 22:05:37 EDT
This request mirrors the request that was accepted for RHEL 5.2.
Comment 2 Ronald Pacheco 2008-03-31 13:59:32 EDT
Per Intel, this patch is necessaery to address a regression thart was
introducced with the patch that resolves BX 313631.

Adding CPU_CLK_UNHALTED:1000000:0:1:1 parameter in /root/.oprofile/daemonrc, we also can collect the performance data.
