  "message": "Acceleration of chacha20 on aarch64 by SVE\n\nThis patch accelerates chacha20 on aarch64 when Scalable Vector Extension\n(SVE) is supported by CPU. Tested on modern micro-architecture with\n256-bit SVE, it has the potential to improve performance up to 20%\n\nThe solution takes a hybrid approach. SVE will handle multi-blocks that fit\nthe SVE vector length, with Neon/Scalar to process any tail data\n\nTest result:\nWith SVE\ntype            1024 bytes   8192 bytes  16384 bytes\nChaCha20        1596208.13k  1650010.79k  1653151.06k\n\nWithout SVE (by Neon/Scalar)\ntype            1024 bytes   8192 bytes  16384 bytes\nchacha20        1355487.91k  1372678.83k  1372662.44k\n\nThe assembly code has been reviewed internally by\nARM engineer Fangming.Fang@arm.com\n\nSigned-off-by: Daniel Hu \u003cDaniel.Hu@arm.com\u003e\n\nReviewed-by: Tomas Mraz \u003ctomas@openssl.org\u003e\nReviewed-by: Paul Dale \u003cpauli@openssl.org\u003e\n(Merged from https://github.com/openssl/openssl/pull/17916)\n",
