geni_i2c_gp...eout_handler(9)

💅 geni_i2c_gp...eout_handler(9) — bestie edition 🎀

okay so this is a Kernel API Manual page, section 9, and the star of the show is the function geni_i2c_gp...eout_handler (yes the name is literally truncated like that, that's just how the header rolls, the full name lives in NAME below, iykyk).

---

✨ NAME ✨

geni_i2c_gpi_multi_xfer_timeout_handler — she handles the multi message transfer timeout. That's her whole job and she ate 💅

---

🦋 SYNOPSIS 🦋

int geni_i2c_gpi_multi_xfer_timeout_handler (struct device *dev , struct
geni_i2c_gpi_multi_desc_xfer *multi_xfer , u32 transfer_timeout_msecs ,
struct completion *transfer_comp );

literally just copy that, don't retype it, no cap 😭

---

🌸 ARGUMENTS 🌸

• dev — Pointer to the corresponding dev node. the main character of the whole device situation honestly 👑
• multi_xfer — Pointer to the geni_i2c_gpi_multi_desc_xfer. yes it's a mouthful, we deal 🫶
• transfer_timeout_msecs — Timeout value in milliseconds. so like, how long we're willing to wait before things get awkward 💀
• transfer_comp — Completion object of the transfer. the little signal that goes "we're so done here" ✨

---

🧚 DESCRIPTION 🧚

okay so here's the vibe: this function waits for the completion of each processed transfer messages based on the interrupts generated upon transfer completion. that's it. that's the whole plot. she sits there, patiently, watching the interrupts come in, and each transfer message gets its moment to finish 🎀

---

⭐ RETURN ⭐

• On success returns 0 🎉
• -ETIMEDOUT on timeout 😭 (the classic "we waited and nothing happened" situation, iconic but tragic)
