Subject: [dpdk-dev] [PATCH v3 0/4] fix performance/cache resource issues with 128-byte cache line targets
Date: Mon, 14 Dec 2015 10:02:52 +0530 [thread overview]
Message-ID: <1450067576-18803-1-git-send-email-jerin.jacob@caviumnetworks.com> (raw)
In-Reply-To: <1449765378-29563-1-git-send-email-jerin.jacob@caviumnetworks.com>
This patchset fixes performance/cache resource issues with 128-byte cache line targets
found in mbuf and bitmap DPDK libraries
Currently, we have two DPDK targets(ThunderX and ppc_64) which are based on
128-bytes cache line size target.
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
For the series,
Acked-by: Konstantin Ananyev <konstantin.ananyev@intel.com>
