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
+ ``-Dplatform=generic`` as a workaround for native compilation or use the
+ ``--cross-file config/arm/arm64_armv8_linux_gcc`` configuration file for cross-compilation.
