> Add hardware-accelerated CRC32 support for riscv64 using the v,zbc,zvbc
> extension
> ---------------------------------------------------------------------------------
>
> Key: HADOOP-19666
> URL: https://issues.apache.org/jira/browse/HADOOP-19666
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: native
> Affects Versions: 3.4.1
> Reporter: Lei Wen
> Priority: Major
> Labels: pull-request-available
>
> This PR implements vector-accelerated CRC32 using the RISC-V V, Zbc and Zvbc
> instruction sets, with full functional verification and performance testing
> completed.
> The implementation uses the vclmul.v and vclmulh.v (carry-less multiply)
> instructions for data folding and computes the final checksum via Barrett
> reduction.
> Key Features:
> 1. Runtime Hardware Detection
> The PR uses kernel hardware probing and cpuinfo parsing to dynamically detect
> hardware support for CRC32 acceleration (via v, zbc, and zvbc extensions) at
> runtime.
> 2. Performance Improvement
> Hardware-accelerated CRC32 achieves a performance boost of over *3x* compared
> to the software implementation.
