intel_vgpu_d...lt_mmio_read(9)

🌸 NAME 🌸

okay so bestie, this page lives in the Kernel API Manual and it's literally about intel_vgpu_default_mmio_read — the default MMIO read handler. That's the whole main-character vibe. The page title is intel_vgpu_d...lt_mmio_read(9), and we're keeping it cute and factual. 💖

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• vgpu — a vGPU. literally the virtual GPU we're working with. 🫶
• offset — access offset. the spot being accessed.
• p_data — data return buffer. the buffer where the data comes back. 📥
• bytes — access data length. how many bytes are in play.

🔥 RETURN 🔥

Zero on success, negative error code if failed. so bestie: zero is the slay outcome, and a negative error code means it did not eat. 💅
