v8 changes: keep using strlen for trusted input string v7 changes: update EAL version map for new public EAL API rollback to use strnlen() passing EAL core option
v6 changes: rename RTE_RING_PAUSE_REP(_COUNT) and set default to 0 rollback to use RTE_MAX_LCORE when checking valid lcore_id for EAL thread v5 changes: reorder some patch and split into addtional two patches rte_thread_get_affinity() return type change to avoid add RTE_RING_PAUSE_REP into config and by default turn off v4 changes: new patch fixing strnlen() invalid return in 32bit icc [03/17] update and add more comments on sched_yield() [16/17] v3 changes: new patch adding sched_yield() in rte_ring to avoid long spin [16/17] v2 changes: add '<number>-<number>' support for EAL option '--lcores' [02/17] 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.
