+Max number of events
+~~~~~~~~~~~~~~~~~~~~
+
+Max number of events in OCTEON TX Eventdev (SSO) are only limited by DRAM size
+and they can be configured by passing limits to kernel bootargs as follows:
+
+.. code-block:: console
+
+        ssopf.max_events=4194304
+
+The same can be verified by looking at the following sysfs entry:
+
+.. code-block:: console
+
+        # cat /sys/module/ssopf/parameters/max_events
+        4194304
+
+The maximum number of events that can be added to SSO by the event adapters such
+as (Rx/Timer) should be limited to the above configured value.
