+OCTEON TX2 SSO Eventdev Driver
+===============================
+
+The OCTEON TX2 SSO PMD (**librte_pmd_octeontx2_event**) provides poll mode
+eventdev driver support for the inbuilt event device found in the **Marvell OCTEON TX2**
+SoC family.
+
+More information about OCTEON TX2 SoC can be found at `Marvell Official Website
+<https://www.marvell.com/embedded-processors/infrastructure-processors/>`_.
+
+Features
+--------
+
+Features of the OCTEON TX2 SSO PMD are:
+
+- 256 Event queues
+- 26 (dual) and 52 (single) Event ports
+- HW event scheduler
+- Supports 1M flows per event queue
+- Flow based event pipelining
+- Flow pinning support in flow based event pipelining
+- Queue based event pipelining
+- Supports ATOMIC, ORDERED, PARALLEL schedule types per flow
+- Event scheduling QoS based on event queue priority
+- Open system with configurable amount of outstanding events limited only by
+ DRAM
+- HW accelerated dequeue timeout support to enable power management
+
+Prerequisites and Compilation procedure
+---------------------------------------
+
+ See :doc:`../platform/octeontx2` for setup information.
+
+Pre-Installation Configuration
+------------------------------
+
+Compile time Config Options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following option can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_PMD_OCTEONTX2_EVENTDEV`` (default ``y``)
+
+ Toggle compilation of the ``librte_pmd_octeontx2_event`` driver.
+
+Debugging Options
