What do I really need in the kernel configuration and kernel command line for IOMMU support?
If I set CONFIG_IOMMU_SUPPORT=y in the kernel configuration then the system starts. If I set CONFIG_IOMMU_SUPPORT=y and CONFIG_INTEL_IOMMU=y in the kernel configuration the system does not start! Setting CONFIG_INTEL_IOMMU also sets CONFIG_IOMMU_IOVA=y CONFIG_IOMMU_API=y CONFIG_DMAR_TABLE=y CONFIG_INTEL_IOMMU_FLOPPY_WA=y automatically. For the kernel command line there are two options: iommu=off|noforce|force|... and intel_iommu=on|off|... What do I really need for the hypervisor "jailhouse"? -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
