## AI overview

Linux 7.4 is slated to merge an AVX-512 optimization for xor_gen(), a function used by Linux software RAID to generate and validate parity blocks for RAID5 and RAID6. The patches report performance gains on AMD Zen 4 and newer CPUs and current Intel server CPUs with AVX-512, subject to final merge-window changes.

## Source excerpt

Over the past few months there have been patches floating around for an AVX-512 optimized xor_gen() for the Linux kernel for that functuon used by the Linux software RAID code. It's been shhowing very nice performance gains with this function being used for generating and validating parity blocks such as for RAID5 and RAID6. The upcoming Linux 7.4 cycle is slated to merge this nice enhancement for benefiting AMD Zen 4 and newer or current Intel server CPUs with AVX-512...
