✨ ish_fw_xfer_ishtp(9) ✨

okay so bestie, welcome to the Kernel API Manual page for ish_fw_xfer_ishtp(9) — yes the (9) means it's a kernel function, we're in the big leagues now 💅

🎀 NAME 🎀

ish_fw_xfer_ishtp — literally the function that loads ISH firmware using the ishtp interface 🫶

---

🌸 SYNOPSIS 🌸

int ish_fw_xfer_ishtp (struct ishtp_cl_data *client_data , const struct
       firmware *fw );

that's the whole signature, no cap — it hands you back an int 🔥

---

🦋 ARGUMENTS 🦋

• client_data — the client data instance, like, the context baddie that knows who's who 💖
• fw — a pointer to the firmware data struct, chillin' in host memory ⭐

---

💜 DESCRIPTION 💜

so this function uses ISH-TP to transfer the ISH firmware from host ➡️ ISH SRAM. iconic behavior honestly 🧚

and the way it does that? the lower layers get to choose — they may use IPC or DMA depending on what the firmware supports 😭 so it's giving flexible, it's giving "we'll figure out the transport later" 🌈

👑 RETURN 👑

• 0 for success, slay ✅
• a negative error code for failure, and we simply do not talk about that 💀
