mei_txe_cou...l_read_slots(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

mei_txe_count_full_read_slots — bestie, this one mimics the me device circular buffer. That's literally its whole thing, it's giving "understudy energy" but make it kernel 🎭

✨ SYNOPSIS ✨

int mei_txe_count_full_read_slots (struct mei_device *dev );

Okay so quick heads up, this page lives in the Kernel API Manual (that's section 9, the fancy "we're talking to kernel devs" section 💅). Ngl the title up top is like, aggressively truncated into mei_txe_cou...l_read_slots(9) because somebody's terminal was not cooperating — but you and me both know the real name, it's mei_txe_count_full_read_slots, periodt.

🎀 ARGUMENTS 🎀

  • dev — the device structure. That's it. That's the whole vibe. You hand it the struct mei_device * and it does its little count 🫶

🌸 RETURN 🌸

Returns always buffer size in dwords count. Not "sometimes", not "depends on the weather" — always. In dwords. Count. Slay, honestly ✨

Lowkey a legend for this: no error path, no < 0 check, no drama. It just tells you the buffer size in dwords every single time. Iconic behaviour 😭

🦋 SEE ALSO 🦋

You're gonna want the whole friend group, not just this one. Kernel file ./drivers/misc/mei/hw-txe.c is home base 🏠 and here's everybody else:

That's the whole page, bestie, no filler, no cap 💀 Now go read your circular buffer docs and hydrate 💧

Sign-off time 🎀: this lil masterpiece ships from ./drivers/misc/mei and it's dated October 2026 — yes, from the future, we stay ahead of schedule 💅✨
