STRUCT IOMMU_HWPT_SELFTEST(9)

✨ struct iommu_hwpt_selftest(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil struct in the kernel API docs — yes the (9) means it's a kernel-API page, not a command you type in your shell, so don't go trying to run it, mwah 💅

---

🎀 NAME 🎀

struct iommu_hwpt_selftest — literally the name and that's it, the original leaves the description blank so I'm not gonna make one up for you, iykyk 🫶

---

🌸 SYNOPSIS 🌸

here's the whole thing, character for character, no cap:

struct iommu_hwpt_selftest {
    __u32 iotlb;
    __u32 pagetable_type;
 };

two __u32 fields, that's the entire struct, it's giving minimal queen 👑

---

🦋 Members 🦋

• iotlb — the default mock iotlb value, and it's set to IOMMU_TEST_IOTLB_DEFAULT. that's the whole description, slay 💜

ngl, pagetable_type is sitting right there in the synopsis with zero explanation in the original — so I'm not inventing lore for it. it exists, that's what we know, periodt 🙈

---

🧚 SEE ALSO 🧚

• Kernel file ./drivers/iommu/iommufd/iommufd_test.h — go read the source bestie, it's right there 💖
• struct iommu_hwpt_invalidate_selftest(9)
• struct iommu_viommu_selftest(9)
• struct iommu_viommu_invalidate_selftest(9)

the whole selftest friend group fr fr, go say hi to all of them 🌈

---

and that's the page!! no options, no exit statuses, no signals, just a tidy lil struct minding its business ⭐

this came from the kernel source dir ./drivers/iommu/iommufd, dated October 2026 — so like, future vibes 👑 that's the sign-off, love u, bye!! 🎀💖✨
