Messages in this thread Patch in this message | | | From | Janakarajan Natarajan <> | Subject | [PATCH v2] x86/kvm/Kconfig: Ensure CRYPTO_DEV_CCP_DD state at minimum matches KVM_AMD | Date | Wed, 27 Jun 2018 11:30:53 -0500 |
| |
Prevent a config where KVM_AMD=y and CRYPTO_DEV_CCP_DD=m thereby ensuring that AMD Secure Processor device driver will be built-in when KVM_AMD is also built-in.
v1->v2: * Removed usage of 'imply' Kconfig option. * Change patch commit message.
Fixes: 505c9e94d832 ("KVM: x86: prefer "depends on" to "select" for SEV")
