Vega 56 drivers, falta de firmware

Question

No kernel nulo do linux 4.13.3_1 estou tendo problemas para fazer com que os drivers amdgpu funcionem.

Saída relevante do dmesg:

[    0.944960] [drm] amdgpu kernel modesetting enabled.
[    0.945421] [drm] initializing kernel modesetting (VEGA10 0x1002:0x687F 0x1002:0x6B76 0xC3).

[   62.431668] amdgpu: probe of 0000:44:00.0 failed with error -11

Estou criando sem o initramfs. Não consigo encontrar a pasta amdgpu abaixo de / lib / modules, mas pode ser porque eles estão incluídos no kernel.

Algumas configurações do kernel:

CONFIG_DRM_AMDGPU=y
CONFIG_DRM_AMDGPU_SI=y
CONFIG_DRM_AMDGPU_CIK=y
CONFIG_DRM_AMDGPU_USERPTR=y
CONFIG_DRM_AMDGPU_GART_DEBUGFS=y

Ter marcado "Incluir blobs de firmware no kernel no binário do kernel".

Eu tenho linux-firmware instalado a partir de xbps.

Edit: Eu tenho amdgpu.exp_hw_support=1 adicionado aos parâmetros do kernel.

Você precisa baixar os arquivos de firmware da sua GPU e copiá-los para /lib/firmware/amdgpu . O kernel deve então poder carregá-los.
