mbx_ctrl_wr32(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mbx_ctrl_wr32 — it's giving "write to the control register" ✨

okay so bestie, welcome to mbx_ctrl_wr32, section 9 of the Kernel API Manual 🎀 — this one's a lil baby function but she's important, so let's get into it 🫶

✨ NAME ✨

mbx_ctrl_wr32 — writes value to reg with base mbx->fwpf_ctrl_base 💖

like... it literally writes a value into a register. that's the whole vibe. no cap 🌸

🌈 SYNOPSIS 🌈

void mbx_ctrl_wr32 (struct mucse_mbx_info *mbx , u32 reg , u32 value );

she takes three things and returns void — so don't be out here expecting a return value, because there isn't one 💀✨

👑 ARGUMENTS 👑

  • mbx — pointer to the MBX structure 🦋 like, the whole context object, she needs it to know where her base address lives
  • reg — register offset 🌟 this is the offset, not the absolute address, iykyk
  • value — value to be written 💅 the actual thing going into the register, the main character of this whole operation fr fr

literally the entire mbx cinematic universe 🌈⭐ go read them all, they ate 💖
