mbx_data_wr32(9)

💅 mbx_data_wr32 — like, the Kernel API Manual page, bestie ✨

okay so welcome to the Kernel API Manual entry for mbx_data_wr32, and no cap, this one is short but she is important. Sit down, grab a strawberry 🍓, and let's get into it.

---

🌸 NAME 🌸

mbx_data_wr32 — writes a value to a register using mbx->fwpf_shm_base as the base. That's it. That's the whole vibe. She writes, she slays, she leaves. 💅

---

✨ SYNOPSIS ✨

void mbx_data_wr32 (struct mucse_mbx_info *mbx , u32 reg , u32 value );

literally three things go in, nothing comes back out (void, periodt), and the register gets a brand new value. iconic behaviour honestly 🫶

---

🎀 ARGUMENTS 🎀

• mbx — a pointer to the MBX structure. yes bestie, the whole struct mucse_mbx_info, hand it over 💖
• reg — the register offset. where we're writing. the address, the location, the moment 📍
• value — the value to be written. this is the actual payload, the main character of the operation 👑

ngl, this page is short enough that you could read it in one sip of your iced coffee, but every single detail still ate. 💀✨

and that's a wrap, babe! 🧚 this little cutie comes from ./drivers/net/ethernet/mucse/r... (the source/version line, bestie, she's giving abbreviated path energy) and it's dated October 2026 — yes, the future, she's ahead of her time. bye bestie, go write some registers 💜🌈
