dfll_force_output(9)

💖 dfll_force_output — Kernel API Manual, section 9 💖

okay so bestie, welcome to dfll_force_output(9) from the Kernel API Manual ✨ this whole page lives in section 9 of the manual, and it's literally all about forcing a fixed output value out of the DFLL. no cap, that's the entire plot 🎀

---

✨ NAME ✨

dfll_force_output — force output a fixed value 💅

---

🌸 SYNOPSIS 🌸

int dfll_force_output (struct tegra_dfll *td , unsigned int out_sel );

---

🦋 ARGUMENTS 🦋

• td — the DFLL instance, your main character 🫶
• out_sel — the value to force output, i.e. the number you're hard-committing to ✨

---

👑 DESCRIPTION 👑

Set the fixed value for force output, and DFLL will output this value. that's it, that's the vibe 💅 it's giving "we're not doing the adaptive thing anymore, we're just saying the number" and honestly? iconic.

💀 reminder bestie: the page says out_sel is the value to force output, and DFLL will output that value. that's the whole documented behavior — don't go inventing extra ✨magic✨ on top of it, iykyk.

k bye ilysm, this page came straight out of ./drivers/clk/tegra and it's dated October 2026, so go forth and force those outputs bestie 🍓💜👑
