✨ NAME ✨

okay so bestie, this page — intel_vgpu_e...te_cfg_write(9) — comes from the Kernel API Manual, and it's all about intel_vgpu_emulate_cfg_write: the function that emulates a vGPU configuration space write. literally the main character of cfg-space writes 💅✨

✨ SYNOPSIS ✨

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

✨ ARGUMENTS ✨

• vgpu — the target vgpu 🎯 that's the one getting written to, iykyk.
• offset — the offset, bestie. that's the spot. 📍
• p_data — write data ptr, aka the pointer to the data being written 🫶.
• bytes — number of bytes to write, so like, how much data we're putting in there 🔥.

Zero on success, and a negative error code if failed. no cap: 0 is the slay outcome, negative means something went 💀.
