ti_sci_reset_set(9)

💅 ti_sci_reset_set(9) — like, the Kernel API Manual, but make it make sense

okay bestie, sit down, grab a strawberry 🍓, because today we're talking about ti_sci_reset_set — the little function that pokes a device's reset line and tells it "you're SO back" or "girl, take a nap." It lives in the Kernel API Manual and it's honestly kind of iconic.

---

✨ NAME ✨

ti_sci_reset_set — program a device's reset. that's it. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

int ti_sci_reset_set (struct reset_controller_dev *rcdev , unsigned long
id , bool assert );

one function, three arguments, zero drama (well, mostly). 🎀

---

🌸 ARGUMENTS 🌸

• rcdev — the reset controller entity. think of it as the main character of the reset world 👑
• id — the ID of the reset you're toggling. yeah you gotta know which one, no cap 🔥
• assert — a boolean flag saying whether we're asserting or deasserting. it's giving "yes or no, pick one" ⭐

---

💖 DESCRIPTION 💖

so this is a common internal function, right? it's the shared lil helper that asserts or deasserts a device's reset using the TI SCI protocol. 🧚

how does it decide? super simple:

• if the assert argument is true, the device's reset gets asserted ✨
• if the assert argument is false, it gets deasserted 😌

and the mechanism itself? it's a read-modify-write procedure, which is exactly what it sounds like, bestie:

1. the current device reset register is read using a TI SCI device operation 👀
2. the new value is set or un-set using the reset's mask 🎯
3. the new reset value is written using another TI SCI device operation ✍️

read, modify, write. three steps. she ate and left no crumbs. 💅

---

🔥 RETURN 🔥

• 0 — for a successful request. slay 🎉
• else — a corresponding error value 😭 (yes, you gotta check it, don't @ me)

---

🎀 SEE ALSO 🎀

• Kernel file ./drivers/reset/reset-ti-sci.c

• ti_sci_reset_status(9)
• ti_sci_reset_of_xlate(9)

go read the whole squad, they're all linked up like a group chat iykyk 🫶

lowkey reminder: this is an internal function, so it's the kind of thing that does its job quietly in the background while other code gets the credit. main character energy, honestly. 🌈

okay that's the whole page, bestie — and before you go, the fine print says it's from ./drivers/reset, dated October 2026, and the page is literally named ti_sci_reset_set(9). cute, right? now go forth and toggle some resets responsibly 💜💀
