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.
