For example,\nspecifying '-mcpu=cortex-a72' doesn't enable it but '+crypto' is required\nin order to enable the feature.\n\nIt is also known that not all the armv8 platforms have the crypto\nextension. For example, Mellanox BlueField has a variant which doesn't have\nit. If crypto enabled binary runs on such a platform, rte_eal_init() fails.\n\nTherefore, an option to control this feature is necessary. It is still\nenabled by default but can be selectively disabled by vendors.\n\nSigned-off-by: Yongseok Koh <yskoh@mellanox.com>\n---\n config/arm/meson.build | 16 +++++++++-------\n config/common_armv8a_linux | 1 +\n drivers/crypto/armv8/Makefile | 4 ++++\n meson_options.txt | 2 ++\n mk/machine/armv8a/rte.vars.mk | 4 ++++\n 5 files changed, 20 insertions(+), 7 deletions(-)", "diff": "diff --git a/config/arm/meson.build b/config/arm/meson.build\nindex 7fa6ed3105..3b53842d08 100644\n--- a/config/arm/meson.build\n+++ b/config/arm/meson.build\n@@ -8,6 +8,8 @@ march_opt = '-march=@0@'.format(machine)\n arm_force_native_march = false\n arm_force_default_march = (machine == 'default')\n \n+crypto_flag = get_option('enable_armv8_crypto') ?
