Faster AES-GCM & AES-XTS Crypto For AMD CPUs With Linux 6.14
Eric Biggers of Google who has pursued countless CPU optimizations within the Linux kernel's crypto subsystem over the years has some noteworthy optimizations coming for AMD processors with the upcoming Linux 6.14 kernel cycle.
Over the weekend several x86 AES-XTS and AES-GCM patches made it into the crypto subsystem's development Git code ahead of the upcoming Linux 6.14 kernel cycle. While just single-digit gains this round, they add up especially with Biggers having delivered some massive triple digit improvements in recent kernel cycles. The Linux 6.14 merge window will kick off in late January while the stable kernel should be out by the end of March and will be found in the likes of Ubuntu 25.04 and Fedora 42.
