exynos5_dmc...events_check(9)

💅 exynos5_dmc_perf_events_check(9) — from the Kernel API Manual, bestie 🎀

okay so you found yourself in the kernel API manual, section 9, and the page is literally called exynos5_dmc...events_check(9). don't let the truncation jump-scare you — it's giving "the title got cut off by man" energy. anyway. let's get into it ✨

🌸 NAME 🌸

exynos5_dmc_perf_events_check — the function that checks the status of the counters. that's it. that's the whole name section. short and iconic. 👑

---

🦋 SYNOPSIS 🦋

void exynos5_dmc_perf_events_check (struct exynos5_dmc *dmc );

no cap, that's the whole signature. returns void, takes exactly one pointer. minimalism ate. 💅

---

🍓 ARGUMENTS 🍓

• dmc — the device whose counters are getting the vibe check. yes, that struct exynos5_dmc * from the synopsis. it's the main character of this function fr fr.

---

✨ DESCRIPTION ✨

so this is the function that gets called from the threaded IRQ (yes, that threaded IRQ, iykyk 💀) and its whole job is:

• check the state of the counters 🔍
• call the approximation for the needed utilization 📈

that's the tea. that's the description. it's a small function with big responsibilities, honestly lowkey relatable. 🫶
