+ if (!cpu_feature_enabled(X86_FEATURE_SEV_SNP))Shouldn't this be a WARN_ON_ONCE()?Since some of these function are called while handling the PSC so I tried to avoid using the WARN -- mainly because if the warn_on_panic=1 is set on the host then it will result in the kernel panic.
But why would KVM be handling PSC requests if SNP is disabled?
