From be2b567018d987591647935a7c9648e9c45e05e8 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Mon, 28 Sep 2020 14:27:17 +0200 Subject: s390x/tcg: Implement CIPHER MESSAGE WITH AUTHENTICATION (KMA) As with the other crypto functions, we only implement subcode 0 (query) and no actual encryption/decryption. We now implement S390_FEAT_MSA_EXT_8.
