STRUCT SMEM_REGION(9)

💖 struct smem_region(9) — Kernel API Manual, bestie edition 💖

okay so this is a page from the Kernel API Manual and it's literally about one little struct, struct smem_region, and we're gonna get into it. no cap, it's short and adorable. 🎀

✨ NAME ✨

struct smem_region — the representation of a chunk of memory used for smem. that's it, that's the vibe. one chunk, one struct, main character energy. 💅

🌸 SYNOPSIS 🌸

here's the whole glow-up, verbatim, don't touch:

struct smem_region {
    phys_addr_t aux_base;
    void __iomem *virt_base;
    size_t size;
 };

three fields. iconic. not one more, not one less. 🦋

💜 Members 💜

• aux_base — the identifier of the aux_mem base. like the name tag at a party but for memory. 🏷️
• virt_base — the virtual base address of the memory that's rockin' this aux_mem identifier. same identifier, but the virtual side of the story. ✨
• size — the size of the memory region. how much memory we're talking about. the actual amount. 🍓
