ENUM IOMMU_HWPT_VTD_S1_FLAGS(9)

🌸 NAME 🌸

enum iommu_hwpt_vtd_s1_flags — bestie, this is the Intel VT-d stage-1 page table entry attributes situation, and it’s literally the enum iommu_hwpt_vtd_s1_flags(9) page from the Kernel API Manual. Come sit with me, this one’s short and cute. 💖

✨ SYNOPSIS ✨

okay so the whole enum is giving exactly this, no cap:

enum iommu_hwpt_vtd_s1_flags {
    IOMMU_VTD_S1_SRE ,
    IOMMU_VTD_S1_EAFE ,
    IOMMU_VTD_S1_WPE

};

💅 Constants 💅

These are the three constants, and yes they each get their own little moment:

• IOMMU_VTD_S1_SRE — Supervisor request. That’s the whole description, bestie. ✨
• IOMMU_VTD_S1_EAFE — Extended access enable. Highkey iconic. 🔥
• IOMMU_VTD_S1_WPE — Write protect enable. Slay. 🎀

mwah 💋 that’s the whole page, bestie. Cute little sign-off tea ☕: source ./include/uapi/linux, dated October 2026, and the footer manual-name moment is enum iommu_h...vtd_s1_flags(9). periodt. 🫶
