STRUCT PCIE_SG_LIST(9)

🎀 NAME 🎀

struct pcie_sg_list — PCIe SGL buffer (contiguous per I/O) ✨

okay so bestie, this is the struct pcie_sg_list(9) page from the Kernel API Manual, and it's giving exactly what the name says: a PCIe SGL buffer that's contiguous per I/O. short, sweet, lowkey iconic — we love to see it 💅

✨ SYNOPSIS ✨

here's the whole struct in all its glory — no cap, this is the exact shape:

struct pcie_sg_list {
    void *pcie_sgl;
    dma_addr_t pcie_sgl_dma;
 };

the way this struct is literally just two fields? obsessed. 🦋

💖 Members 💖

vibe check: two members, both main character energy:

• pcie_sgl — the PCIe native SGL for NVMe devices 🦋
• pcie_sgl_dma — the physical address 📍
