The DPDK package in RHEL7 won't be updated to new main releases anymore. It's not quite as clear for a user compiling their own DPDK. CentOS7 is in maintenance mode until mid 2024 and will only get security or critical fixes. You could still have a user on CentOS7 compiling their own DPDK from the latest tarballs. It feels like an unlikely combination but maybe someone knows of a user like that. As the distro version won't get latest software packages, it seems reasonable that latest DPDK is not supported either, but there would need to be some advance warning. 20.11 LTS will provide bugfix/security that should be ok on CentOS7 until Jan 2023. >> >> If we decide to drop RHEL 7 support, does it mean we can generally use >> standard C11 atomics? > What is the next RHEL version we support officially?
