💅 mei_me_hcbww_write(9) — like, the whole glow-up

okay so bestie, welcome to the Kernel API Manual ✨ this one's a tiny lil function but she's iconic in her own right, and we're gonna get into it. take my hand 🫶

🌸 NAME 🌸

mei_me_hcbww_write — write 32bit data to the host circular buffer 💫

that's it. that's the whole vibe. she writes. she's 32 bits of pure purpose. no cap.

🦋 SYNOPSIS 🦋

void mei_me_hcbww_write (struct mei_device *dev , u32 data );

look at her 😭 two arguments, returns nothing (void, she gives nothing back and honestly? respect). no return value, no drama, just vibes and a write. periodt.

🎀 ARGUMENTS 🎀

  • dev — the device structure 🖥️ like, the whole device situation. she needs to know which device she's writing to, obviously, iykyk.
  • data — the 32bit data to be written to the host circular buffer 💾 the actual payload!! the main character of this whole operation fr fr. 32 bits of it, exactly, not a bit more.
ngl, that's the entire argument list. two of them. she's lowkey minimal and we stan a low-effort queen 👑

🔥 SEE ALSO 🔥

okay this is the part where she flexes her entire friend group 💅 and bestie, the friend group is huge. all of these live in the kernel file ./drivers/misc/mei/hw-me.c:

like… that's the entire squad 😭 every single one of them, no skips, no cuts. she said "invite everyone or don't invite me" and honestly? valid. 🧚

aaaand that's the page!! short, sweet, 32 bits of circular-buffer realness 🌈 hope you feel so informed rn bestie 🫶
