The ARM PMU counters are limited in number. Even for counting similar events, the PMU driver allocates a new counter. Hence, counters configured to count similar events are shared. This was only possible for the kernel clients, but not for user-space clients. Hence, as an extension to this, the kernel and the user-space are now able to share the similar events. The counters can be shared between user-space only clients, kernel only clients, and among user-space and kernel clients. The kernel and user's attr->type (hardware/raw) and attr->config should be same for them to share the same counter.
