> Subject: [dpdk-dev] [PATCH v1 00/15] support multi-pthread per core
> 
> The patch series contain the enhancements of EAL and fixes for libraries
> to run multi-pthreads(either EAL or non-EAL thread) per physical core.
> Two major changes list as below:
> - Extend the core affinity of each EAL thread to 1:n.
>   Each lcore stands for a EAL thread rather than a logical core.
>   The change adds new EAL option to allow static lcore to cpuset assginment.
>   Then a lcore(EAL thread) affinity to a cpuset, original 1:1 mapping is the special case.
> - Fix the libraries to allow running on any non-EAL thread.
>   It fix the gaps running libraries in non-EAL thread(dynamic created by user).
>   Each fix libraries take care the case of rte_lcore_id() >= RTE_MAX_LCORE.
> 
> Thanks a million for the comments from Konstantin, Bruce, Mirek and Stephen in RFC review.

> Cunming Liang (15):
>   eal: add cpuset into per EAL thread lcore_config
>   eal: new eal option '--lcores' for cpu assignment
>   eal: add support parsing socket_id from cpuset
>   eal: new TLS definition and API declaration
>   eal: add eal_common_thread.c for common thread API
>   eal: add rte_gettid() to acquire unique system tid
>   eal: apply affinity of EAL thread by assigned cpuset
>   enic: fix re-define freebsd compile complain
>   malloc: fix the issue of SOCKET_ID_ANY
>   log: fix the gap to support non-EAL thread
>   eal: set _lcore_id and _socket_id to (-1) by default
>   eal: fix recursive spinlock in non-EAL thraed
>   mempool: add support to non-EAL thread
>   ring: add support to non-EAL thread
>   timer: add support to non-EAL thread
