Red Hat released a new enterprise version a year ago... perhaps it's time for their customers to upgrade, if they want to use the latest and greatest version of DPDK.


Just to be clear - I wasn't arguing for the direct use of GCC built-ins.


The GCC __atomic built-ins (called directly, or via a DPDK wrapper) do 
have some advantages over C11 atomics. One is that GCC supports 128-bit 
atomic operations, on certain architectures. <rte_atomic.h> already has 
a 128-bit compare-exchange. Also, since the GCC built-ins seem not to 
bother with architectures where atomics would be implemented by means of 
a lock, they are a little easier to use than <stdatomic.h>.


> Are all the other tools required for building DPDK (in the required versions) included in RHEL7, or do we require developers to install/upgrade any other tools anyway? If so, why not also GCC? DPDK can be used in a cross compilation environment, so we are not requiring RHEL7 users to replace their GCC 4.7 default compiler.

If we are stuck on GCC 4.8, the documentation should be updated.
