intel_punit_ipc_command(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay so bestie, this is the manual page for intel_punit_ipc_command(9) from the Kernel API Manual — and it's literally the function for an IPC command with data and pointers. periodt. 💅

✨ SYNOPSIS ✨

int intel_punit_ipc_command (u32 cmd , u32 para1 , u32 para2 , u32 *in ,
       u32 *out );

🎀 ARGUMENTS 🎀

  • cmd — the IPC command code. that's the main-character argument fr fr. 👑
  • para1 — first 8bit parameter. if you're not using it, set it to 0 — no cap. 🫶
  • para2 — second 8bit parameter. same energy: set it to 0 if it's not used. 💖
  • in — input data. it's 32bit for BIOS cmd, and two 32bit for GTD and ISPD. yes, the way that detail matters. 😭
  • out — output data. that's where the output goes, bestie. ✨

🌸 DESCRIPTION 🌸

send an IPC command to P-Unit with a data transaction. that's the whole vibe. 💫

🌈 RETURN 🌈

returns an IPC error code, or 0 on success. so like, 0 is the slay outcome. ✅

🦋 SEE ALSO 🦋

  • Kernel file ./drivers/platform/x86/intel/punit_ipc.c — go read it, iykyk. 📖
lowkey reminder: this is kernel API business, so keep those parameter details exactly as written — especially the 0 defaults and the 32bit / two-32bit situation. 💅

shoutout to the source/version ./drivers/platform/x86/intel and the date October 2026 — that's the cute lil sign-off, bestie. 🎀✨💖
