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

TODO: archwiki -> kernel-mode-setting -> early-kms-start

For AMDGPU: in /etc/mkinitcpio.conf include "amdgpu" in MODULES=(...). Otherwise Xorg might not start properly.

# "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.
