What I'm doing here is insane GPU driver prototype for @GreenteaOS

What I'm doing here is a GPU driver for Linux as a prototype for future graphics stack of the @GreenteaOS

Aim

To support AMD GCN 1.0+ GPUs. And Intel/Nvidia ones that conform to Resource binding Tier 3 and Resource heap Tier 2.

This project is a part of future Driver Reusability Initiative (to be announced).

Supported GPUs

• AMD Radeon R7 200 Series PCI\VEN_1002&DEV_6610&REV_00 Oland GFX6 (gfx601)
• Radeon RX 5500 XT PCI\VEN_1002&DEV_7340&REV_C5 Navi GFX10 (gfx1012)

Later GCN/RDNA GPUs will reuse huge parts of GCN 1.0 code.

• Intel(R) HD Graphics 500 PCI\VEN_8086&DEV_5A85&REV_0B Gen. 9 (Skylake)
• Intel(R) UHD Graphics 630 PCI\VEN_8086&DEV_TBA&REV_TBA Gen. 9.5 (Kaby Lake)
• Intel(R) UHD Graphics 750 PCI\VEN_8086&DEV_TBA&REV_TBA Gen. 12 (Rocket Lake-S)
• Intel(R) Iris(R) Xe Graphics PCI\VEN_8086&DEV_TBA&REV_TBA G7 Gen. 12 (Tiger Lake-U)

Step by step

• Create IOCTL API to control driver from userspace
• Init GPU engine and setup command buffer
• Mode setting
• Draw anything on screen

Limitations

Only fullscreen applications supported, no desktop GUI! Use only for secondary GPU with extra screen (or use extra inputs and switch dynamically).

Build

Use make to build kmodule kernel mode driver.
