💖 ti_sci_cmd_set_latency_constraint(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for ti_sci_cmd_set_latency_constraint(9). This page is short and sweet, and it is literally here to explain one function: setting an LPM resume latency constraint. The way that this is such a specific little guy. 💅

🌸 NAME 🌸

ti_sci_cmd_set_latency_constraint — Set LPM resume latency constraint. periodt. ✨

✨ SYNOPSIS ✨

int ti_sci_cmd_set_latency_constraint (const struct ti_sci_handle
       *handle , u16 latency , u8 state );

🎀 ARGUMENTS 🎀

• handle — pointer to TI SCI handle. bestie, this is the handle you pass in. 🫶
• latency — maximum acceptable latency (in ms) to wake up from LPM. keep the unit in mind: it's ms, no cap. ⏱️
• state — The desired state of latency constraint: set or clear. so it's giving "set or clear" energy, okay? 🦋

🌸 RETURN 🌸

0 if all went well, else returns appropriate error value. so 0 is the slay outcome; otherwise it returns the appropriate error value and you deal with it. 😭
