A compact patch that provides AES and GCM implementations that utilize the ARMv8 Crypto Extensions. The config flag is MBEDTLS_ARMV8CE_AES_C, which is disabled by default as we don't do runtime checking for the feature. The new implementation lives in armv8ce_aes.c. Provides similar functionality to https://github.com/ARMmbed/mbedtls/pull/432 Thanks to Barry O'Rourke and others for that contribtion. Tested on a Cortex A53 device and QEMU. On a midrange phone the real AES-GCM throughput increases about 4x, while raw AES speed is up to 10x faster. When cross-compiling, you want to set something like: export CC='aarch64-linux-gnu-gcc' export CFLAGS='-Ofast -march=armv8-a+crypto' scripts/config.pl set MBEDTLS_ARMV8CE_AES_C QEMU seems to also need export LDFLAGS='-static' Then run normal make or cmake etc. |
