+ *
+ * NB events are events measuring L3 cache, Hypertransport
+ * traffic. They are identified by an event code >= 0xe00.
+ * They measure events on the NorthBride which is shared
+ * by all cores on a package. NB events are counted on a
+ * shared set of counters. When a NB event is programmed
+ * in a counter, the data actually comes from a shared
+ * counter. Thus, access to those counters needs to be
+ * synchronized.
+ *
+ * We implement the synchronization such that no two cores
+ * can be measuring NB events using the same counters. Thus,
+ * we maintain a per-NB allocation table. The available slot
+ * is propagated using the event_constraint structure.
+ *
+ * We provide only one choice for each NB event based on
+ * the fact that only NB events have restrictions. Consequently,
+ * if a counter is available, there is a guarantee the NB event
+ * will be assigned to it. If no slot is available, an empty
+ * constraint is returned and scheduling will eventually fail
+ * for this event.
+ *
+ * Note that all cores attached the same NB compete for the same
+ * counters to host NB events, this is why we use atomic ops. Some
+ * multi-chip CPUs may have more than one NB.
+ *
+ * Given that resources are allocated (cmpxchg), they must be
+ * eventually freed for others to use. This is accomplished by
+ * calling amd_put_event_constraints().
+ *
+ * Non NB events are not impacted by this restriction.
