Hi,
We installed a perfmon2 enabled kernel on a Intel Core machine laptop. Note this
is not a Core 2 machine. permfon2 did not identify the processor as a Core
processor. Looking through the code it appears that the family 6 model 14
processors are not identified or supported. The attached patch should enable
proper identification of the processor.
