queue_alloc_page(9)

💅 queue_alloc_page(9) — the Kernel API Manual page, bestie edition ✨

okay so picture this: you're deep in the Kernel API Manual, section 9, and you land on queue_alloc_page. that's our main character today. she's a little function, she allocates a page for a Queue, and honestly? she ate. 🎀

---

🌸 NAME 🌸

queue_alloc_page — allocate page for Queue. that's it, that's the job. no cap. 💖

---

✨ SYNOPSIS ✨

int queue_alloc_page (struct hinic_hwif *hwif , u64 **vaddr , u64 *paddr
, void ***shadow_vaddr , size_t page_sz );

like, look at her signature. five whole arguments. she's that girl. 🔥

---

🦋 ARGUMENTS 🦋

• hwif — HW interface for allocating DMA. this is the plug, the source of truth, the whole vibe for getting your DMA going 💫
• vaddr — the virtual address gets returned in this address. so you pass it in and she fills it in for you. lowkey generous of her 🫶
• paddr — and here's where the physical address comes back home. one for virt, one for phys, balanced as all things should be ✨
• shadow_vaddr — the VM area gets returned right here, and its whole purpose in life is holding WQ page addresses. she's the keeper of the receipts 📋
• page_sz — page size of each WQ page. yeah, every single WQ page gets this size. don't come for her, she's specific 💅

ngl the double/triple pointers in here are giving "trust the process" energy. u64 **, void ***… she's not doing simple, she's doing thorough. 🙈

---

💜 DESCRIPTION 💜

so what does she return? iconically concise:

• 0 — Success 🎉 slay
• negative — Failure 😭 it's giving "try again later"

that's the whole description. no paragraphs, no lore, just vibes and a return value. periodt.

🔥 SEE ALSO 🔥

the whole friend group shows up for this one. every single one of them:
