💖 clk_save_context — saving clock context for poweroff 💖

okay so bestie, you found a page from the Kernel API Manual and it's literally about clk_save_context(9). pull up a chair, this one's short but it's important, no cap 🎀

✨ NAME ✨

clk_save_context — save clock context for poweroff 🫶

🌸 SYNOPSIS 🌸

int clk_save_context (void );

🦋 ARGUMENTS 🦋

  • void — no arguments. that's it. nothing. zero. the emptiest function signature you ever did see 💅

⭐ DESCRIPTION ⭐

so what does it do? it saves the context of the clock register for powerstates where the contents of the registers will legitimately just be lost 😭 like, gone gone.

the way that this happens is deep within the suspend code — and because of that depth, locking is not necessary. no mutex, no spinlock, none of that. it's already chill down there. 🧚

lowkey important: registers losing their contents is a real thing in these powerstates, which is exactly why this function exists. it's giving "save your game before the power goes out" energy 🔥

sign-off szn: this page lives in ./include/linux, and it's stamped October 2026 🎀 go save those registers before the powerstate takes them, ily 💖🦋
