Release Note: Provide ChaCha20 Intrinsics on x86_64 and aarch64 Platforms

    XMLWordPrintable

Details

    Description

      This feature delivers optimized intrinsic implementations for the ChaCha20 cipher supplied by the SunJCE provider. These optimized routines are designed for x86_64 chipsets that support the AVX, AVX2 and/or AVX512 instruction sets, and aarch64 chips supporting the Advanced SIMD instruction set.
      These intrinsics are enabled by default on supporting platforms, but may be disabled by providing the `-XX:-UseChaCha20Intrinsics` command-line option to Java. Flags that control intrinsics require the option` -XX:+UnlockDiagnosticVMOptions`.
