mei_txe_check_and_ack_intrs(9)

💅 mei_txe_check_and_ack_intrs(9) — the Kernel API Manual page your group chat needed

okay so bestie, welcome to mei_txe_check_and_ack_intrs, straight out of the Kernel API Manual (section 9, where all the good stuff lives ✨). this one is a little function with a big job: it takes the messy multi BAR interrupt situation and squishes it into one single bit mask, then goes ahead and acknowledges the interrupts. it's giving "I'll organize the group chat" energy, fr fr 💅

✨ NAME ✨

mei_txe_check_and_ack_intrs — translate a multi BAR interrupt into a single bit mask and acknowledge the interrupts 🎀

like, that's the whole thing. one function, two jobs, zero drama. slay.

---

🌸 SYNOPSIS 🌸

bool mei_txe_check_and_ack_intrs (struct mei_device *dev , bool do_ack );

it returns a bool, it takes two things, and yes the spacing in there is exactly how the manpage wrote it — we do not touch the sacred formatting 🔥

---

🦋 ARGUMENTS 🦋

• dev — the device structure 👑 this is your main character, the device we're working with.
• do_ack — acknowledge interrupts 💖 this is the little yes/no switch that says whether we should actually go ahead and acknowledge the interrupts or not.

two arguments. that's it. we love a low-maintenance king.

---

⭐ RETURN ⭐

it returns true if it found interrupts to process 💀 not gonna lie, that's the entire return story. true = there was something to do. no cap. 🫶

and that's the page, bestie 🎀 go forth and acknowledge those interrupts.
