 DPDK can be compiled either natively on BlueField platforms or cross-compiled on
 an x86 based platform.
 
+.. note::
+
+   Starting with DPDK 25.03, using the ``-mcpu=cortex-a78ae`` option is required for optimal performance on BlueField-3.
+   If your compiler does not support this option, you may need to use a newer GCC version or specify
