exynos5_dmc_..._events_calc(9)

✨ exynos5_dmc_perf_events_calc ✨

hey bestie, welcome to the Kernel API Manual page exynos5_dmc_..._events_calc(9) — yes the title is abbreviated like that, and the full function name is literally right here. 💅

🎀 NAME 🎀

exynos5_dmc_perf_events_calc — Calculate utilization ✨

🦋 SYNOPSIS 🦋

void exynos5_dmc_perf_events_calc (struct exynos5_dmc *dmc , u64 diff_ts );

🌸 ARGUMENTS 🌸

• dmc — device for which the counters are going to be checked 👀
• diff_ts — time between last interrupt and current one ⏱️

💖 DESCRIPTION 💖

okay so this function calculates the needed utilization for the devfreq governor. the way it works is it prepares values for busy_time and total_time based on elapsed time between interrupts, which approximates utilization. that’s the whole vibe — no cap. ✨
