AMD Graphics Card

Good overview (table):

AMDGPU

From gentoo wiki one should use AMDGPU e.g. for:

AMD Zen 2 "4000" series 7nm laptop APUs

AMDGPU (mandatory packages)

  • archwiki -> AMDGPU -> Installation

  • archwiki -> Xorg -> AMD

  • archwiki -> Lenovo-IdeaPad-S540-13ARE (Ryzen 7 4800U CPU)

  • archwiki -> Hardware_video_acceleration -> ATI/AMD

  • HW-video-accel verification:

    • run vainfo and vdpauinfo as non-root

  • amdgpu module

    • see also: https://wiki.archlinux.org/title/AMDGPU#Loading
    • The amdgpu kernel module is supposed to load automatically on system boot.
    • It is possible it loads, but late, after the X server requires it. In this case:
      • Include "amdgpu" in MODULES=(...) of /etc/mkinitcpio.conf
# "DRI driver for 3D acceleration"
depends=(mesa)
# "DDX driver for 2D acceleration"       
depends+=(xf86-video-amdgpu)
# "Vulkan support"
depends+=(vulkan-radeon)
# "HW-vide-acceleration: VA-API"
depends+=(libva-mesa-driver)
# "HW-vide-acceleration: VDPAU"
depends+=(mesa-vdpau)

AMDGPU PRO (optional packages)

  • archwiki -> AMDGPU#AMDGPU_PRO
  • archwiki -> AMDGPU_PRO

The amdgpu-pro-installer contains proprietary components for AMDGPU (it works on top of AMDGPU).

Quote about the opengl part (from archwiki -> AMDGPU):

From Radeon Software 18.50 vs Mesa 19 benchmarks article: When it comes to OpenGL games, the RadeonSI Gallium3D driver simply dominates the proprietary AMD OpenGL driver.

# proprietary OpenGL implementation
depends+=(amdgpu-pro-libgl)
# proprietary OpenCL implementation
depends+=(opencl-amd)
# proprietary Vulkan implementation
depends+=(vulkan-amdgpu-pro)
# Advanced Media Framework implementation
depends+=(amf-amdgpu-pro)
