mei_hcsr_set_hig(9)

💅 mei_hcsr_set_hig — a whole vibe check ✨

okay so bestie, this is a page from the Kernel API Manual (mei_hcsr_set_hig(9), kernel level, very demure very mindful) and it's about one (1) tiny function that does one (1) tiny thing. and yet. here we are. 🎀

---

✨ NAME ✨

mei_hcsr_set_hig — set host interrupt (set H_IG) 💫

that's it. that's the whole job. it sets the host interrupt. also known as setting H_IG. two names for the same slay little bit flip. iykyk.

---

🦋 SYNOPSIS 🦋

void mei_hcsr_set_hig (struct mei_device *dev );

look at that. returns void (nothing, nada, it just does the thing and leaves), takes a pointer to a struct mei_device named dev. no cap, that's the entire signature. write it exactly like that, spaces and all — the manpage is not playing about the ); at the end. 💀

---

🌸 ARGUMENTS 🌸

• dev — the device structure 🫶

that's the one and only argument. the device structure. it's giving "one job, one argument, zero drama." you hand it the device struct, it goes and sets that host interrupt. main character energy from a function that literally returns nothing.

yes, mei_me_intr_disable(9) shows up twice in that list. no, i'm not editing the guest list. it's in the original, it stays. 🙈

also note there's me_intr_disable(9) and me_intr_clear(9) at the top with no i after the me — those are different functions from mei_me_intr_disable(9) and mei_me_intr_clear(9). do not merge them. this is exactly the kind of thing where one missing letter ruins your whole afternoon. 💀

and that's the page!! tiny function, giant SEE ALSO section, zero regrets. go forth and set that host interrupt, bestie. 💖🔥
