Subject: [PATCH v13 01/26] [TEMP] x86/kvm/Kconfig: Have KVM_AMD_SEV select ARCH_HAS_CC_PLATFORM
Date: Thu, 18 Apr 2024 14:41:08 -0500 [thread overview]
Message-ID: <20240418194133.1452059-2-michael.roth@amd.com> (raw)
In-Reply-To: <20240418194133.1452059-1-michael.roth@amd.com>
From: "Borislav Petkov (AMD)" <bp@alien8.de>
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.
