This patchset doesn't introduce any performance degradation for 64-bytes cache line size targets. v1..v2 - Introduced new cache macro definitions as Suggested by Konstantin - Reduced the cache alignment requirement for 128-byte cache targets in slow-path data structures to save the memory - Verified x86(a 64byte cacheline target) does not have any impact on these changes by verifying the md5sum of app/test,app/testpmd, app/testacl binaries with or without this patch set v2..v3 revert the cache alignment of rte_ring_debug_stats, rte_mempool_debug_stats structures v3..v4 replaced RTE_CACHE_MIN_LINE_SIZE with RTE_CACHE_LINE_MIN_SIZE as suggested by olivier.matz@6wind.com For clean git am, "config: cleanup existing RTE_CACHE_LINE_SIZE selection scheme" patch needs to apply first Jerin Jacob (4): eal: Introduce new cache line macro definitions mbuf: fix performance/cache resource issue with 128-byte cache line targets bitmap: optimize for 128-bytes cache line targets cache/slow-path: reduce cache align requirement for 128-byte cache targets app/test/test_mbuf.c | 2 +- lib/librte_eal/common/include/rte_memory.h | 16 ++++++++++++++++ .../linuxapp/eal/include/exec-env/rte_kni_common.h | 4 +++- lib/librte_ether/rte_ethdev.h | 4 ++-- lib/librte_mbuf/rte_mbuf.h | 2 +- lib/librte_sched/rte_bitmap.h | 10 +++++----- 6 files changed, 28 insertions(+), 10 deletions(-) -- 2.1.0
