throttlectl_cpu_level_cfg(9)

💖 NAME 💖

okay so bestie, this is throttlectl_cpu_level_cfg(9) from the Kernel API Manual — the kernel function that programs CCROC NV_THERM level config. That’s the whole name vibe ✨

✨ SYNOPSIS ✨

void throttlectl_cpu_level_cfg (struct tegra_soctherm *ts , int level );

🎀 ARGUMENTS 🎀

• ts — a pointer to a struct tegra_soctherm, literally handing over the soctherm struct 💅
• level — describing the level LOW/MED/HIGH of throttling, so it tells you which throttle level we’re setting up.

🔥 DESCRIPTION 🔥

okay so real talk: it’s necessary to set up the CPU-local CCROC NV_THERM instance with the M/N values desired for each level. This function does that. No cap 🫶

This function pre-programs the CCROC NV_THERM levels in terms of the pre-configured "Low", "Medium", or "Heavy" throttle levels, which are mapped to THROT_LEVEL_LOW, THROT_LEVEL_MED, and THROT_LEVEL_HVY. So like, it’s giving level config main character energy 🔥
