[AMD Official Use Only - General] Hello Boris, >> This function is required to ensure that IOMMU supports the SEV-SNP >> feature before enabling the SNP feature and calling SNP_INIT. >> This IOMMU support check is done in the AMD IOMMU driver with the >> iommu_sev_snp_supported() function so it is exported by the IOMMU >> driver and called by sev module >What sev module? I meant the kvm-amd module. >The call to iommu_sev_snp_supported() is done by snp_rmptable_init() which is in arch/x86/kernel/sev.c. AFAICT. >And that is not a module. But function exports are done for modules. >So that export looks superfluous. Yes realized this is called in arch/x86/kernel/sev.c, so yes the export is not needed and will remove it. Thanks, Ashish
