From 54f5f47b6055c6b57cbc41a440f8ca8b2ec4275a Mon Sep 17 00:00:00 2001 From: "Borislav Petkov (AMD)" Date: Wed, 27 Mar 2024 16:43:15 +0100 Subject: [PATCH] x86/kvm/Kconfig: Have KVM_AMD_SEV select ARCH_HAS_CC_PLATFORM The functionality to load SEV-SNP guests by the host will soon rely on cc_platform* helpers because the cpu_feature* API with the early patching is insufficient when SNP support needs to be disabled late. Therefore, pull that functionality in.
