💖 adapt_cap_to_t_adapt_l0l3(9) 💖

okay so bestie, welcome to the Kernel API Manual page for adapt_cap_to_t_adapt_l0l3(9) — it's giving "tiny math gremlin that tells you the TAdapt value," and honestly? iconic. 💅

🎀 NAME 🎀

adapt_cap_to_t_adapt_l0l3 — Calculate TAdapt_L0_L3 from adapt capability. That's the whole assignment, no cap. ✨

✨ SYNOPSIS ✨

u64 adapt_cap_to_t_adapt_l0l3 (u32 adapt_cap );

🫶 ARGUMENTS 🫶

• adapt_cap — Adapt capability. That's the input, bestie; hand it over and let the function cook. 🍓

💅 DESCRIPTION 💅

For PAM-4, the formula is literally right here, and yes you need to keep it exact:

For PAM-4: IF (ADAPT_range = FINE) TADAPT_L0_L3 = 2^9 x ADAPT_length
       ELSE IF (ADAPT_range = COARSE) TADAPT_L0_L3 = 2^9 x (2^ADAPT_length)

Then it returns the calculated TAdapt value in terms of Unit Intervals (UI). Periodt. 🫶
