Does anyone here remember why the __rte_ring_enqueue/dequeue_elems_64/128() functions support unaligned object arrays, when the __rte_ring_enqueue/dequeue_elems_32() functions require 4 byte aligned object arrays?
As I remember, we added 'unaligned' to be able to use rte_ring with elements that might have smaller alignment.
For 32 - as I remember we never explicitly require 4B aligned objects for the rings ... Am I missing something here? My guess, we just never hit such problem so it gets unnoticed. Probably worth updating 32-bit version too with explicit 'unaligned' type.
I'm wondering if the compiler could do better with a simpler implementation than the manually implemented loop unrolls, and if the unalignment silliness would stand in the way. Med venlig hilsen / Kind regards, -Morten Brørup
