fsl_asrc_set_ideal_ratio(9)

💅 fsl_asrc_set_ideal_ratio(9) — from the Kernel API Manual, bestie 🎀

okay so real talk, this one's a little function from the kernel API manual and it's lowkey iconic for doing exactly one job and doing it well. no notes. ✨

---

🌸 NAME 🌸

fsl_asrc_set_ideal_ratio — it calculates and sets the ratio, but only for Ideal Ratio mode. that's it. that's the whole vibe. no cap, it's mode-specific and it knows it. 💅

---

✨ SYNOPSIS ✨

int fsl_asrc_set_ideal_ratio (struct fsl_asrc_pair *pair , int inrate ,
       int outrate );

three args, one int coming back at you. clean, simple, slay. 🫶

---

🦋 ARGUMENTS 🦋

• pair — pointer to pair. like, the pair. the one and only. you gotta hand it over. 👑
• inrate — input rate. the rate coming in. 🍓
• outrate — output rate. the rate going out. the way these two are literally a matched set… chemistry. 💖

---

🔥 DESCRIPTION 🔥

so the ratio itself? it's a 32-bit fixed point value with 26 fractional bits. yes bestie, 32 whole bits, and 26 of them are fractional. that's the entire description and honestly it ate. 🌈

heads up: the original doc says this is for Ideal Ratio mode only — so don't be out here using it for other modes and then acting surprised, iykyk. 🙈
