intel_vgpu_reg_imr_handler(9)

✨ NAME ✨

intel_vgpu_reg_imr_handler — Generic IMR register emulation write handler. Okay bestie, you're in the Kernel API Manual, and this is the function that handles the generic IMR register emulation write-handler moment. Slay. 💅

💅 SYNOPSIS 💅

int intel_vgpu_reg_imr_handler (struct intel_vgpu *vgpu , unsigned int
       reg , void *p_data , unsigned int bytes );

🫶 ARGUMENTS 🫶

• vgpu — a vGPU. Literally the vGPU we're doing the emulation for. 💖
• reg — the register offset written by guest. 👑
• p_data — the register data written by guest. ✨
• bytes — the register data length. 🎀

🌸 DESCRIPTION 🌸

This function is used to emulate the generic IMR register bit change behavior. That's the whole assignment: generic IMR register bit changes get emulated here, no cap. 🦋

🎀 RETURN 🎀

Returns 0 on success, and a negative error code if it failed. So zero = slay, negative = something went off. 😭
