ishtp_hbm_cl_hdr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ishtp_hbm_cl_hdr — bestie, it's a kernel API manual page (section 9) ✨

okay so we're deep in the kernel API manual, section 9, and this one is literally called ishtp_hbm_cl_hdr. say it with me: i-s-h-t-p h-b-m c-l h-d-r. iconic mouthful. let's get into it 🫶

🌸 NAME 🌸

ishtp_hbm_cl_hdr — the little function that constructs your client hbm header 💖

✨ SYNOPSIS ✨

void ishtp_hbm_cl_hdr (struct ishtp_cl *cl , uint8_t hbm_cmd , void *buf
, size_t len );

that's it. that's the whole signature. void, so it gives you nothing back — it just does the thing and vibes. no cap 💅

🎀 ARGUMENTS 🎀

  • cl — your client. the whole reason we're here 🦋
  • hbm_cmd — the host bus message command. it's a uint8_t, so keep it smol and tidy ✨
  • buf — buffer for the cl header. this is where the magic lands 🍓
  • len — buffer length. yes bestie, you gotta tell it how big 🔥

🌈 DESCRIPTION 🌈

Initialize HBM buffer. that's the assignment, that's the whole assignment 🙈

like, it sets up the HBM buffer, periodt. lowkey does exactly what the name says and nothing else — main character energy of a function that knows its lane 👑

ngl there's not a ton of prose here, so don't come for me — the original says "Initialize HBM buffer" and I'm not bout to invent lore that isn't in the source, fr fr 💀

👑 SEE ALSO 👑

bestie the cross-reference list is long and honestly kind of a flex. here's every single one, no skips, no cuts, we ate 🍽️

The kernel file lives at ./drivers/hid/intel-ish-hid/ishtp/hbm.c — that's the home base 🏠

and then the whole squad:

look at that roster. it's giving family reunion 😭💜

okay that's the page!! sourced from ./drivers/hid/intel-ish-hid/ishtp, dated October 2026, and yeah — this was ishtp_hbm_cl_hdr(9) the whole time 💅✨ go initialize that buffer bestie, you got this 🫶
