dev_pm_opp_...pufreq_table(9)

💅 dev_pm_opp_free_cpufreq_table — free the cpufreq table 💅

okay so this one lives in the Kernel API Manual, bestie, and it's honestly such a clean little function. no drama, no weird edge cases, just a good old-fashioned cleanup. let's get into it 🧚

---

🌸 SYNOPSIS 🌸

void dev_pm_opp_free_cpufreq_table (struct device *dev , struct
       cpufreq_frequency_table **opp_table );

that's it. that's the whole signature. two args, returns void, does exactly what it says on the tin. iconic behaviour honestly ✨

---

🎀 ARGUMENTS 🎀

• dev — the device we're doing this whole operation for 🫶 like, which device's stuff are we freeing? this one.
• opp_table — the table to free. yes, the one you're about to hand over to the void. bye bestie 👋

tiny heads up: opp_table is a struct cpufreq_frequency_table ** — a double pointer. so you're passing in the address of your table pointer. don't overthink it, just pass it the way the synopsis shows you 💅

---

🦋 DESCRIPTION 🦋

so basically this frees up the table that was allocated by dev_pm_opp_init_cpufreq_table. that's it. that's the whole vibe. it's the other half of that call — you init it, you free it, balance is restored to the universe 🌈

no cap, this is the cleanest kind of kernel function: the humble cleanup. no surprises, no hidden magic, just freeing what you allocated. the way that memory management stays balanced is genuinely so satisfying ngl 😭

and that's the page, bestie! 🎀 this little icon came from the kernel source at ./drivers/opp, dated October 2026, and it's filed under the name dev_pm_opp_...pufreq_table(9) — yes the truncated name is real, no i didn't do that, the manpage did 💀 anyway go free your tables, stay balanced, and remember: every alloc deserves its free 💜🦋✨
