✨ NAME ✨

t7xx_dpmaif_bat_alloc — Allocate the BAT ring buffer. that's it, that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

int t7xx_dpmaif_bat_alloc (const struct dpmaif_ctrl *dpmaif_ctrl ,
struct dpmaif_bat_request *bat_req , const enum bat_type buf_type );

she takes three args and returns an int, no cap. take a screenshot before you call her 📸

---

💖 ARGUMENTS 💖

• dpmaif_ctrl — Pointer to DPMAIF context structure. your main character struct, literally the whole context of the operation 🫶
• bat_req — Pointer to BAT request structure. this is the request bestie herself, she's holding the receipts 🧾
• buf_type — BAT ring type. lowkey just tells her which flavor of BAT ring we're doing 💅

---

🦋 DESCRIPTION 🦋

okay so here's what she actually does, and it's giving two-for-one:

This function allocates the BAT ring buffer shared with the HW device — yes, shared, like a group chat with the hardware — and it also allocates a buffer used to store information about the BAT skbs for further release. so she's not just handing you memory, she's setting up the little filing cabinet so those skbs can be properly released later. organized queen 👑

🔥 RETURN 🔥

• 0 — Success. we love a zero, we celebrate a zero 🎉
• -ERROR — Error code. not the moment, but at least she's honest about it 😭
