# AMD Graphics Card
|
|
|
|
Good overview (table):
|
|
|
|
* [wiki.gentoo.org/Radeon](https://wiki.gentoo.org/wiki/Radeon#Feature_support)
|
|
* [wiki.gentoo.org/AMDGPU](https://wiki.gentoo.org/wiki/AMDGPU#Feature_support)
|
|
|
|
## 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
|
|
* 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`
|
|
* https://wiki.archlinux.org/title/AMDGPU#Specify_the_correct_module_order
|
|
* `amdgpu` before `radeon`
|
|
|
|
```shell
|
|
# "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)
|
|
```
|
|
|
|
**Verification**:
|
|
|
|
```shell
|
|
lspci -k | grep -EA3 'VGA|3D|Display'
|
|
```
|
|
|
|
Example output:
|
|
|
|
```
|
|
Kernel driver in use: amdgpu
|
|
Kernel modules: amdgpu
|
|
```
|
|
|
|
### 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). (AUR: Search by `Package Base`, Keywords `amdgpu-pro-installer`)
|
|
|
|
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.
|
|
|
|
```shell
|
|
# 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)
|
|
```
