Also, when > vcpu_blocking/unblocking, SVM needs to update the is-running bit in > the IOMMU IRTE. Both are achieved via calling amd_iommu_update_ga(). > > However, if GA mode is not enabled for the pass-through device, > IOMMU driver will simply just return when calling amd_iommu_update_ga. > > Signed-off-by: Suravee Suthikulpanit <suravee.suthikulpanit@xxxxxxx> > --- I forgot nitpicks in the office before going on a vacation, ;) Reviewed-by: Radim Krčmář <rkrcmar@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
