STRUCT IOMMU_PAGE_RESPONSE(9)

🌸 struct iommu_page_response(9) 🌸

okay bestie, buckle up — this is a page from the Kernel API Manual and it's honestly kinda iconic. Let's get into it 💅

---

✨ NAME ✨

struct iommu_page_response — literally just the generic page response info, no cap. That's the whole vibe. 🦋

---

🎀 SYNOPSIS 🎀

struct iommu_page_response {
    u32 pasid;
    u32 grpid;
    u32 code;
 };

like... three little u32s and she's serving main character energy ✨

💖 Members 💖

• pasid — the Process Address Space ID. yes that's the whole description, she's lowkey mysterious 💅
• grpid — the Page Request Group Index. keeping the group together, as she should 🫶
• code — the response code, and it comes from enum iommu_page_response_code (iykyk — go look at that page if you want the actual codes, this one's not telling 😭)
