This series adds support for enabling VMSA SEV features for SEV-ES and SEV-SNP guests. Since that is already supported for IGVM files, some of that code is moved to generic path and reused.
Debug-swap is already supported in KVM today, while patches for enabling Secure TSC have been accepted for the upcoming kernel release. Roy, I haven't been able to test IGVM, so would be great if that is tested to confirm there are no unintended changes there. Changes since v1 (*): - Move patch enabling use of KVM_SEV_INIT2 for SEV-ES guests before patch enabling use of debug-swap VMSA SEV feature (Tom) - Only issue KVM_SET_TSC_KHZ if user has specified a tsc-frequency for Secure TSC (Tom) - Patch 9/9 is new and refactors check_sev_features in preparation for future SEV feature support (Tom) - Minor updates to commit log and comments (Tom) - Collect review tags from Tom (*) http://lkml.kernel.org/r/[email protected] - Naveen Naveen N Rao (AMD) (9): target/i386: SEV: Generalize handling of SVM_SEV_FEAT_SNP_ACTIVE target/i386: SEV: Ensure SEV features are only set through qemu cli or IGVM target/i386: SEV: Consolidate SEV feature validation to common init path target/i386: SEV: Validate that SEV-ES is enabled when VMSA features are used target/i386: SEV: Enable use of KVM_SEV_INIT2 for SEV-ES guests target/i386: SEV: Add support for enabling debug-swap SEV feature target/i386: SEV: Add support for enabling Secure TSC SEV feature target/i386: SEV: Add support for setting TSC frequency for Secure TSC target/i386: SEV: Refactor check_sev_features() target/i386/sev.h | 4 +- target/i386/sev.c | 170 +++++++++++++++++++++++++++++++++++++--------- qapi/qom.json | 16 ++++- 3 files changed, 155 insertions(+), 35 deletions(-) base-commit: 95b9e0d2ade5d633fd13ffba96a54e87c65baf39 -- 2.51.0
