Subject: [dpdk-dev] [PATCH 1/2] build: add option for armv8 crypto extension
Date: Wed,  1 May 2019 18:58:05 -0700	[thread overview]
Message-ID: <20190502015806.41497-1-yskoh@mellanox.com> (raw)

Per armv8 crypto extension support, make build always enable it by default
as long as compiler supports the feature while meson build only enables it
for 'default' machine of generic armv8 architecture. For example,
specifying '-mcpu=cortex-a72' doesn't enable it but '+crypto' is required
in order to enable the feature.

It is also known that not all the armv8 platforms have the crypto
extension. For example, Mellanox BlueField has a variant which doesn't have
it. If crypto enabled binary runs on such a platform, rte_eal_init() fails.

Therefore, an option to control this feature is necessary. It is still
enabled by default but can be selectively disabled by vendors.
