The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=5daf8ed625af70ebb7e4740ab98a6054e9e52329 commit 5daf8ed625af70ebb7e4740ab98a6054e9e52329 Author: Timothy Pearson <tpearson@raptorengineering.com> AuthorDate: 2025-09-10 16:54:24 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2025-09-11 16:08:05 +0000 ossl: Add GCM support on powerpc64/powerpc64le (POWER8+) Separate ossl's existing AES-NI GCM implementation into a common ossl_aes_gcm.c and add conditionals to switch between OpenSSL's AES-NI and POWER8 GCM routines depending on the architecture. Since the existing AVX-512 implementation is less agnostic, move it into a separate ossl_aes_gcm_avx512.c.
