This was initially added in 2003 and only supported in the simple CPUs. It's oddly specific since there are no other similar event queues for, for instance, stores, branches, system calls, etc. Given that this seems like a historical oddity which is only partially supported and would be very hard to support on more diverse CPU types like KVM or fast model which don't generally have hooks for counts of specific instruction types.
