@SparkiDev I've got a few RISC-V targets here now, so I will try this on actual HW. |

@SparkiDev says AES XTS is not yet support with RISC-V ASM. Note: I tried to use |

@SparkiDev is this RISC-V ASM PR ready for merge? I can’t tell if you are planning to push anything else to it. |
Add implementations of AES for ECB/CBC/CTR/GCM/CCM for RISC-V using assembly. Assembly with standard/scalar cryptography/vector cryptographt instructions.

Fixed --enable-all to work. |

AES RISC-V 64-bit ASM: ECB/CBC/CTR/GCM/CCM

@dgarske - question on the benchmarks fix data size vs fixed time: In the vs Then for comparison your ran this for both: The output on The output on Why the difference in fixed data size vs fixed time? Additionally, perhaps just nit-picky, but curious: it appears there was also difference in vs It appears that In any case - that's an astonishing performance boost by @SparkiDev :) |

The size of data processed is the number of 1048576 byte (=1MB) buffers encrypted/decrypted. I have no idea why the number of bits in SP changed though. |
