From: Jerin Jacob Date: Sun, 8 Oct 2017 12:44:07 +0000 (+0530) Subject: event/octeontx: introduce specialized mbox message copy X-Git-Tag: spdx-start~1580 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=aecb8e093b523db55e4d4bca65fe7dbb5eb17440;p=dpdk.git event/octeontx: introduce specialized mbox message copy Some of the internal toolchain versions create unaligned memory access fault when copying from 17-31B buffer using memcpy. Subsequent patches in this series will be using 17-31B mbox message. Since the mailbox message copy comes in slow path, changing memcpy to byte-per-byte copy to workaround the issue.
