(Discuss in Talk:Intel graphics#TGL/RKL GuC Submission)

Reason: Despite Intel's documentation, Tiger Lake and Rocket Lake GPUs may actually support enable_guc=3, and have a default of enable_guc=1. For 32-bit Vulkan support, install the lib32-vulkan-intel package. For Vulkan support ( Ivy Bridge and newer), install the vulkan-intel package.Beside this functionality, this package is generally not recommended, see note below. For the DDX driver which provides 2D acceleration in Xorg, install the xf86-video-intel package.For 32-bit application support, also install the lib32-mesa or lib32-mesa-amber package from the multilib repository.This driver has better performance and stability for Gen 7 and older hardware. mesa-amber is the legacy Mesa package which includes the classic (non-Gallium3D) drivers for Gen 2 hardware and later.This is the recommended choice for Gen 8 and later hardware. mesa is the up-to-date Mesa package which includes the modern Gallium3D drivers for Intel's Gen 3 hardware and later.

Install one of the following packages, which provide the DRI driver for 3D acceleration.

See Xorg#Driver installation to identify your card.

Intel's Gen N hardware does not refer to the generation of the CPU, it refers to the generation of the GPU, which is different from the generation of the CPU.

PowerVR-based graphics ( GMA 3600 series) are not supported by open source drivers.
