Intel Tiger Lake (Gen12) Graphics Driver for macOS

Overview

This is a graphics driver for Intel Tiger Lake (Gen12) integrated GPUs, designed for macOS.

##Current Limitations Currently it only opens accelrator user clients for surface and display releted, no command sumbission and metal. Need support from experts......

Features

• GPU Command Submission: Hardware-accelerated rendering via GuC (Graphics Microcontroller)
• Memory Management: GEM (Graphics Execution Manager) and GTT (Graphics Translation Table)
• Display Support: Framebuffer, mode setting, and DP (DisplayPort).
• Metal Integration: Full Metal framework support for GPU acceleration (Needs work)
• Power Management: Runtime PM and GT power management
• Interrupt Handling: GT and display interrupt processing

System Requirements

• macOS (10.15+)
• Intel Tiger Lake GPU (Device IDs: 0x9a40-0x9a78)
• Supported PCI Device: 8086:9A49
