okay so bestie, welcome to the Kernel API Manual — this page is intel_gvt_i2..._gmbus_write(9), and the function we're hyping up is intel_gvt_i2c_handle_gmbus_write ✨

intel_gvt_i2c_handle_gmbus_write — emulate gmbus register mmio write. That's the whole name-and-summary moment, no cap 💅

✨ SYNOPSIS ✨

       int intel_gvt_i2c_handle_gmbus_write (struct intel_vgpu *vgpu , unsigned
       int offset , void *p_data , unsigned int bytes );

🎀 ARGUMENTS 🎀

• vgpu — a vGPU, the virtual GPU bb in question 🫶
• offset — reg offset, literally where we're looking 📍
• p_data — data return buffer, the buffer for the data coming back 🎀
• bytes — access data length, iykyk 💫

🦋 DESCRIPTION 🦋
