[Gems-users] Question about the coherence statistics!

[<adash@xxxxxxx>]

I am interested in statistics of snoopy cache coherence
protocols for invalidations(true-sharing invalidations and
false-sharing invalidations),resulting misses and data
subsequently evicted from cache. 

I was not able to locate any of these in the ruby statistics
to understand shared memory access pattern of the benchmarks.
I especially need to study the behaviour of a cache & snoop
controller snooping on the bus and therefore wanted to know
from the statistics what % of time is this controller active.

Could anyone please let me know if this statistics can be
obtained by any means and which files to I need to look at for
the same?

Thanks a lot
