Subject: [PATCH 3/5] x86/kvm/Kconfig: Have KVM_AMD_SEV select ARCH_HAS_CC_PLATFORM
Date: Wed, 27 Mar 2024 16:43:15 +0100 [thread overview]
Message-ID: <20240327154317.29909-4-bp@alien8.de> (raw)
In-Reply-To: <20240327154317.29909-1-bp@alien8.de>
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.
