Linux 6.15 Crypto Subsystem Delivers Faster AES-CTR For AMD Zen 5 & Other x86_64 CPUs
The cryptography subsystem updates for the in-development Linux 6.15 merge window are quite exciting with some optimizations for modern x86_64 Intel/AMD processors enticing us the most.
Merged last week were all of the crypto updates for Linux 6.15. This includes dropping the legacy compression interface, enhancing the scatterwalk API, Kerberos5 algorithms added, dropping some obsolete SIMD fallback code, adding a new “0x1134” PCI device ID in the AMD CCP driver for an unknown product, and a variety of fixes.
Most significant to end-users with these crypto updates is the new VAES-based AES-CTR optimized version for benefiting newer Intel and AMD processors. This is the patch series I wrote about back in February within New Linux…
