Hi all Currently PostgreSQL only implements hardware support for CRC32 checksums for the x86_64 architecture. Some ARMv8 (AArch64) CPUs implement the CRC32 extension which is implemented by inline assembly, so they can also benefit from hardware acceleration in IO-intensive workloads.
I would like to propose the patch to optimize crc32c calculation with Arm64 specific instructions. The hardware-specific code implementation is used under #if defined USE_ARMCE_CRC32C_WITH_RUNTIME_CHECK. And the performance is improved on platforms: cortex-A57, cortex-A72, cortex-A73, etc. I'll create a CommitFests ticket for this submission. Any comments or feedback are welcome.
