Use rte_atomic equivalent
Jerin,
I'm looking for an equivalent, but I can't seem to find one. Here
I'm assigning 'id' with the incremented value of worker_idx in one
statement.
However, rte_atomic32_add just increments the variable and returns void,
so I'd have to use two statements, losing the atomicity.
static inline void
rte_atomic32_add(rte_atomic32_t *v, int32_t inc)
There's a second reason why I can't use the rte_atomics, and that's
because worker_idx is a volatile.
Maybe we could add new atomic functions in the future to address this?
Thanks,
Dave.
