📦 version 7.3.1, in nixpkgs unstable

💅 mctrl_gpio_disable_ms_sync(9) — like, the Kernel API Manual one 💅

okay so bestie, welcome to the Kernel API Manual page for mctrl_gpio_disable_ms_sync, and honestly? this little function is doing the most so your modem-control lines can chill tf out. 🎀

✨ NAME ✨

mctrl_gpio_disable_ms_sync — disable irqs and handling of changes to the ms lines, and wait for any pending IRQ to be processed

no cap, that's the whole vibe: it turns the IRQ party off, stops handling changes to the ms lines, and then — this is the important part, bestie — it waits for any pending IRQ to be processed before it dips. 🦋

🌸 SYNOPSIS 🌸

void mctrl_gpio_disable_ms_sync (struct mctrl_gpios *gpios );

yeah so it returns void (nothing back, she's not a gossip 💅), takes one argument, and it's literally just:

struct mctrl_gpios *gpios

iconic. simple. to the point.

🫶 ARGUMENTS 🫶

  • gpios — gpios to disable. that's it, that's the whole argument, she's the one getting switched off ✨

👑 SEE ALSO 👑

okay so if you wanna keep reading (and you should, iykyk), go look at the Kernel file ./drivers/tty/serial/serial_mctrl_gpio.c — that's where all the lore lives, fr fr. and then there's the whole friend group:

like, mctrl_gpio_disable_ms_no_sync(9) is literally her sibling who doesn't wait around — but this one? this one is the sync one, and she will wait for that pending IRQ. main character energy honestly. 😭🔥

💀 quick vibe check reminder: the sync in the name is not decorative — it means wait for any pending IRQ to be processed. don't skip that part, bestie.

and that's the page!! 🍓 brought to you by the source/version ./drivers/tty/serial, dated October 2026 — mwah, kisses, go read your kernel source, ily, bye!! 💖🧚🌈⭐
