Hi Everyone, On Linux I can check for the presence of optional cpu features AES, PMULL, SHA1 and SHA2 using getauxval(3). It works for both Aarch32 and Aarch64. Also see "When to use AT_HWCAP or AT_HWCAP2", https://sourceware.org/ml/libc-help/2017-08/msg00012.html. I'm not having any luck determining the sysctl's to use for the same under the BSDs. How do I determine availability of AES, PMULL, SHA1 and SHA2 on FreeBSD? If possible, I'd like to know how to look this stuff up on FreeBSD since I am getting poor search results. Thanks in advance.
