issei_heci_...message_recv(9)

📦 version 7.3.1, in nixpkgs unstable

💖 issei_heci_setup_message_recv — bestie edition 💖

okay so this is a page from the Kernel API Manual, and it's about issei_heci_setup_message_recv — the little function whose whole job is grabbing the setup message response back from the firmware. yes. that's it. that's the vibe. 💅

🌸 NAME 🌸

issei_heci_setup_message_recv — literally just receiving the setup message response from firmware, no cap 🫶

✨ SYNOPSIS ✨

int issei_heci_setup_message_recv (struct issei_device *idev );

like, that's the whole signature. one argument, returns an int, iconic behavior honestly 👑

🎀 ARGUMENTS 🎀

  • idev — the device structure 💖 (yes, the one, the main character of this whole operation)

🦋 RETURN 🦋

  • 0 on success 🎉
  • <0 on error 😭
fr fr check that return value, bestie. 0 = we ate. anything <0 = something went sideways.

🌈 SEE ALSO 🌈

so if you wanna go deeper (and you know you do 👀), the kernel file lives here:

./drivers/misc/issei/hw_heci.c

and here's the whole friend group, all of them referenced, all of them linked, not a single one skipped because we don't do that here:

like it's giving "one big found family of HECI helpers" and i'm obsessed 💀💖

🧚 sign-off 🧚

this lil beauty comes from the source path ./drivers/misc/issei, dated October 2026, and the version tag is issei_heci_...message_recv(9) — same energy as the header, cute and recursive like that 🌸✨

now go forth, call your function, check your return value, and slay the firmware handshake, bestie 💅👑💜
