cpufreq_cpu_get(9)

✨ NAME ✨

okay bestie, welcome to the Kernel API Manual page for cpufreq_cpu_get(9) — the one that returns the policy for a CPU and marks it as busy 🫶

🌸 SYNOPSIS 🌸

struct cpufreq_policy * cpufreq_cpu_get (unsigned int cpu );

🎀 ARGUMENTS 🎀

• cpu — the CPU you wanna find the policy for, no cap 🔥

💅 DESCRIPTION 💅

So here's the vibe: cpufreq_cpu_get calls cpufreq_cpu_get_raw to obtain a cpufreq policy for cpu, and then it increments the kobject reference counter of that policy. It returns a valid policy on success, or NULL on failure 😭

The policy that comes back from this function has to be released with the help of cpufreq_cpu_put, so its kobject reference counter gets balanced properly. Like, do not ghost that release step — it's giving "mandatory balance check" for real 💀

bestie reminder: cpufreq_cpu_put is the matching energy. get it, then put it. periodt 💅
