GUEST_READ GUEST_WRITE address ranges?

Is it possible to define a data probe for a range of addresses. In other words, GUEST_READ triggers a data probe when a particular address is read. Is it possible to define a data probe for a range of address where an event will be generated whenever a range is read or written to.

Hi

Currently the GUEST_{READ, WRITE} data probes only allow the user to specify a single linear address(LA). How large of a LA range do you want probe?

It would be arbitrary; I am trying to characterize memory access

behavior of a process or an OS ultimately. I am not too concerned with

the overhead this might add to the application as I would only do this

for profiling purposes. I want to determine location/frequency of

memory accesses.

I could deal with just logging page accesses rather than a specific

linear address.
