💖 qed_fw_overlay_mem_alloc(9) — it's giving "kernel API manual" ✨

okay so bestie, we're in the Kernel API Manual today and the star of the show is qed_fw_overlay_mem_alloc 🎀 — she allocates and fills the FW overlay memory. both!! multitasking icon 👑

---

✨ NAME ✨

qed_fw_overlay_mem_alloc — Allocates and fills the FW overlay memory. literally that's her whole job and she ate 💅

---

🦋 SYNOPSIS 🦋

struct phys_mem_desc * qed_fw_overlay_mem_alloc (struct qed_hwfn *p_hwfn
, const u32 *const fw_overlay_in_buf , u32 buf_size_in_bytes );

three args, one pointer out, no cap 🫶

---

🌸 ARGUMENTS 🌸

• p_hwfn — HW device data. the hardware device info, the main character of the struct world 👑
• fw_overlay_in_buf — The input FW overlay buffer. your input buffer, coming in hot 🔥
• buf_size_in_bytes — The size of the input FW overlay buffer in bytes. and listen — it must be aligned to dwords ⚠️ like, that's not a suggestion, that's a requirement, fr fr

---

⭐ RETURN ⭐

A pointer to the allocated overlays memory, or NULL in case of failures 😭 so yeah — check your pointer before you use it, bestie, that's self-care 💖
