Subject: [dpdk-dev] [PATCH v3 4/4] cache/slow-path: reduce cache align requirement for 128-byte cache targets
Date: Mon, 14 Dec 2015 10:02:56 +0530 [thread overview]
Message-ID: <1450067576-18803-5-git-send-email-jerin.jacob@caviumnetworks.com> (raw)
In-Reply-To: <1450067576-18803-1-git-send-email-jerin.jacob@caviumnetworks.com>
slow-path data structures need not be 128-byte cache aligned.
Reduce the alignment to 64-byte to save the memory.
No behavior change for 64-byte cache aligned systems as minimum
cache line size as 64.
