intel_gvt_i...aux_ch_write(9)

💅 NAME 💅

okay so bestie, welcome to the Kernel API Manual — yes, we're doing kernel docs now, we're that girl ✨

intel_gvt_i2c_handle_aux_ch_write — it emulates an AUX channel register write. lowkey iconic of it tbh 🎀

---

✨ SYNOPSIS ✨

void intel_gvt_i2c_handle_aux_ch_write (struct intel_vgpu *vgpu , int
port_idx , unsigned int offset , void *p_data );

no cap, that's the whole signature — it returns void, so it just does the thing and doesn't even tell you how it went 💀

🫶 ARGUMENTS 🫶

• vgpu — a vGPU. yes girl, the virtual one 👑
• port_idx — port index. which port? this port 🦋
• offset — reg offset. the register location, so we know where we're poking around
• p_data — write ptr. it's a pointer, and we're writing through it, periodt

---

🌸 DESCRIPTION 🌸

This function is used to emulate AUX channel register write. that's it, that's the vibe — it's giving "one job, doing it well" 🧚

like, the guest writes to the AUX channel register and this little legend steps in and emulates it so the vGPU doesn't have to know it's living in a simulation 🙈✨

🌈 okay that's the page!! mwah 💖 this lil doc lives in ./drivers/gpu/drm/i915/gvt, it's dated October 2026, and it's filed under the manual name intel_gvt_i...aux_ch_write(9) — yes the title is truncated, we don't know why, we don't ask, we just slay 🎀🫶
