From 6c2c7bf5803c150d0f86ddde3590a15e26614921 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Wed, 21 Apr 2021 19:11:19 -0700 Subject: [PATCH] KVM: SVM: Enable SEV/SEV-ES functionality by default (when supported) Enable the 'sev' and 'sev_es' module params by default instead of having them conditioned on CONFIG_AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT. The extra Kconfig is pointless as KVM SEV/SEV-ES support is already controlled via CONFIG_KVM_AMD_SEV, and CONFIG_AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT has the unfortunate side effect of enabling all the SEV-ES _guest_ code due to it being dependent on CONFIG_AMD_MEM_ENCRYPT=y.
