[dpdk-dev] [PATCH v10 0/8] Add stack library and new mempool handler

[Thomas Monjalon]

04/04/2019 12:01, Gage Eads:
> This patchset introduces a stack library, supporting both lock-based and
> lock-free stacks, and a lock-free stack mempool handler.
> 
> The lock-based stack code is derived from the existing stack mempool handler,
> and that handler is refactored to use the stack library.
> 
> The lock-free stack mempool handler is intended for usages where the rte
> ring's "non-preemptive" constraint is not acceptable; for example, if the
> application uses a mixture of pinned high-priority threads and multiplexed
> low-priority threads that share a mempool.
> 
> Note that the lock-free algorithm relies on a 128-bit compare-and-swap[1],
> so it is currently limited to the x86_64 platform.

Applied (with a few minor changes), thanks for bringing this new library.
