📦 version 7.3.1, in nixpkgs unstable

💌 wx_obtain_mbx_lock_pf(9) — bestie edition

okay so this is a page from the Kernel API Manual, and honestly? it's a tiny little icon and we're gonna stan it properly. the function is wx_obtain_mbx_lock_pf and its whole personality is obtain mailbox lock. that's it. that's the vibe. 🎀

✨ NAME ✨

wx_obtain_mbx_lock_pf — obtain mailbox lock 🔒

🦋 SYNOPSIS 🦋

int wx_obtain_mbx_lock_pf (struct wx *wx , u16 vf );

like yes, that's the whole signature, and no, we're not skipping a single character of it, bestie. iykyk 💅

🌸 ARGUMENTS 🌸

  • wx — pointer to the HW structure 🫶 (yes it's literally just a pointer, and it's doing main character energy, we love that for it)
  • vf — the VF index ✨
not me triple-checking that there are exactly two arguments and no sneaky hidden ones 🙈 — there are two. that's the whole cast.

💖 RETURN 💖

returns 0 on success and -EBUSY on failure 😭 — so like, if you see -EBUSY, that's the universe gently telling you "she's busy rn, try again," no cap.

🔥 SEE ALSO 🔥

first up, the Kernel file this lives in, and we're citing it exactly as given:

./drivers/net/ethernet/wangxun/libwx/wx_mbx.c

and then the whole friend group, aka the entire mbx squad, in this exact order 🧚:

like, that's fifteen whole references and every single one of them made the list — no one gets left behind 💜

vibe check final: two args, one lock, one return value, fifteen SEE ALSOs. it's giving "small function, big friend group." periodt. 👑

okay that's the page!! this was sourced from ./drivers/net/ethernet/wangxun... (the page literally truncates it like that, and i'm not about to invent the rest, so it stays exactly that way, bestie 🍓) and dated October 2026 — so like, future-core of it all ⭐ signing off with a wx_obtain_mbx_lock_pf(9) and a curtsey 💅✨🦋🌸🎀💖
