geni_load_se_firmware(9)

💖 geni_load_se_firmware(9) — bestie's guide to the kernel API manual 💖

okay so like, this is geni_load_se_firmware(9), and yes the manual name is literally part of the name, we love a self-titled moment 👑

---

✨ NAME ✨

geni_load_se_firmware — loads the firmware for an SE, based on the protocol. that's it, that's the vibe 🎀

---

🌸 SYNOPSIS 🌸

int geni_load_se_firmware (struct geni_se *se, enum geni_se_protocol_type protocol);

like, it returns an int, it takes two things, slay 💅

---

🦋 ARGUMENTS 🦋

• se — pointer to the serial engine we're concerned about. the main character of this whole function, honestly 🫶
• protocol — the protocol type that's gonna be used with the SE. think UART, SPI, I2C. pick your fighter ✨

---

🧚 DESCRIPTION 🧚

okay so here's the tea ☕ — this function retrieves the firmware name from the device properties, and then it sets the transfer mode (that's FIFO or GSI DMA, pick one) based on the device tree configuration. very "read the room, read the DT" of it 💅

then, plot twist: it enforces FIFO mode for the UART protocol, because UART lowkey doesn't have GSI DMA support. so if you're on UART, FIFO it is, no negotiating, periodt 🔥

after that it requests the firmware and loads it into the SE. go little firmware go 🦋

---

⭐ RETURN ⭐

• 0 on success 💖
• a negative error code on failure 😭
