mshv_chunk_stride(9)

💅 mshv_chunk_stride(9) — like, the whole kernel API manual vibe ✨

okay so bestie, we're in the Kernel API Manual today and the star of the show is mshv_chunk_stride(9). this is a section 9 page, iykyk 👑

---

🌸 NAME 🌸

mshv_chunk_stride — literally just computes the stride for mapping guest memory 🫶

---

✨ SYNOPSIS ✨

unsigned int mshv_chunk_stride (struct page *page , u64 gfn , u64
page_count );

that's the whole signature, no cap, copy it exactly the way it is 😌

---

🎀 ARGUMENTS 🎀

• page — the page to check for huge page backing 👀 like, is this thing huge-page-backed or not, that's the question
• gfn — the guest frame number for the mapping, iconic little coordinate fr fr
• page_count — total number of pages in the mapping 💫 the whole squad

---

🦋 DESCRIPTION 🦋

so what does it actually do. it determines the appropriate stride (in pages) for mapping guest memory. main character energy honestly 💅

the way it works: it uses the huge page stride if the backing page is huge and the guest mapping is properly aligned. otherwise? it falls back to single page stride. no drama, just vibes 🌈

bestie note: both conditions matter — huge backing page and proper alignment. miss one and you're on the single-page path, periodt 💀

---

🔥 RETURN 🔥

Stride in pages. that's it. that's the return value 🍓
