ENUM IOMMU_HW_INFO_TYPE(9)

💖 NAME 💖

enum iommu_hw_info_type — IOMMU Hardware Info Types, straight from the Kernel API Manual. This is the enum iommu_hw_info_type(9) page bestie, and it's literally giving hardware-info-type energy ✨💅

✨ SYNOPSIS ✨

Okay so here's the whole enum, no cap:

enum iommu_hw_info_type {
    IOMMU_HW_INFO_TYPE_NONE ,
    IOMMU_HW_INFO_TYPE_DEFAULT ,
    IOMMU_HW_INFO_TYPE_INTEL_VTD ,
    IOMMU_HW_INFO_TYPE_ARM_SMMUV3 ,
    IOMMU_HW_INFO_TYPE_TEGRA241_CMDQV ,
    IOMMU_HW_INFO_TYPE_AMD

};

🎀 Constants 🎀

• IOMMU_HW_INFO_TYPE_NONE — this is what the drivers output when they do not report hardware info, periodt 💀
• IOMMU_HW_INFO_TYPE_DEFAULT — this is the input you use to request a default type, slay 🫶
• IOMMU_HW_INFO_TYPE_INTEL_VTD — the Intel VT-d iommu info type, iconic 🔥
• IOMMU_HW_INFO_TYPE_ARM_SMMUV3 — the ARM SMMUv3 iommu info type, we love to see it 🌸
• IOMMU_HW_INFO_TYPE_TEGRA241_CMDQV — the NVIDIA Tegra241 CMDQV (extension for ARM SMMUv3) info type, highkey a mouthful but okay 💅
• IOMMU_HW_INFO_TYPE_AMD — the AMD IOMMU info type, main character energy 👑
