okay so bestie, welcome to the Kernel API Manual — yes it's ipc_pcie_alloc_skb(9), and yes she's iconic 🎀

---

✨ NAME ✨

ipc_pcie_alloc_skb — allocate an uplink SKB for the given size. that's it, that's the whole vibe 💖

---

🌸 SYNOPSIS 🌸

struct sk_buff * ipc_pcie_alloc_skb (struct iosm_pcie *ipc_pcie , size_t
size , gfp_t flags , dma_addr_t *mapping , int direction , size_t
headroom );

like literally just call her and she gives you a struct sk_buff *, no cap ✨

---

🦋 ARGUMENTS 🦋

• ipc_pcie — pointer to struct iosm_pcie. she's the main character here, know her 🫶
• size — size of the SKB required. yes, the size. the SKB one. the required one 💅
• flags — allocation flags. flags gonna flag 🚩
• mapping — copies either mapped IOVA add. or converted Phy address. (that "add." is their wording bestie, i'm not touching it 🙈)
• direction — DMA data direction. which way is she going 👀
• headroom — header data offset. room for the header, giving headroom, very self-explanatory slay 💀

---

👑 RETURN 👑

pointer to ipc_skb on success 🌈, NULL on failure 😭 — so like, check her before you use her fr fr
