Hi, For DPDK 20.11 the make system is no longer support. Basically the default DPDK build enables all drivers when dependencies are met. Please refer to https://doc.dpdk.org/guides/prog_guide/build-sdk-meson.html section 61.3 for disabling certain driver to compile. Unfortunately for DPDK 20.11 there is no way to only enabling QAT sym but leave QAT asym disabled as they are now combined as “QAT crypto” driver and are enabled/disabled together.

After I checked the documentation, I didn't find any clear solution. So I would like to know if there is any way to initialize sym qat pmd only in DPDK version 20.11. BRs, Samuel
