clk_bulk_prepare(9)

💖 clk_bulk_prepare(9) 💖

okay so bestie, this one's from the Kernel API Manual and it's lowkey one of those functions you'll meet the second you start messing with clock frameworks. it's called clk_bulk_prepare and fr fr it's giving "get the whole squad ready" energy 👑

---

✨ NAME ✨

clk_bulk_prepare — prepare a set of clocks 🎀

like, not one clock. a set of them. a whole little friend group of clocks, all getting prepared together. we love a group activity 💅

---

🦋 SYNOPSIS 🦋

int clk_bulk_prepare (int num_clks , const struct clk_bulk_data *clks );

that's the whole vibe: you hand it a count and a table, it hands you back an int. iconic signature honestly 💜

---

🌸 ARGUMENTS 🌸

• num_clks — the number of clk_bulk_data 👀 like, how many entries are in the table. count your blessings, count your clocks.
• clks — the clk_bulk_data table being prepared ✨ this is the actual lineup of clocks getting their moment.

🧚 DESCRIPTION 🧚

so here's the tea ☕ clk_bulk_prepare may sleep, which is exactly what differentiates it from clk_bulk_enable. that's not a vibe, that's a whole technical distinction — do NOT call this one from somewhere you can't sleep, bestie 😭 that's the caveat and it's kind of important.

it returns 0 on success, and -EERROR otherwise. so like, zero means slay, anything else means go read the error code and figure out what went wrong 🫶

heads up: "may sleep" is the main character detail here. it's literally the difference between this function and clk_bulk_enable, so don't sleep on it (pun fully intended 🙈).
