![]() Use the MODULES=(amdgpu) mkinitcpio method but do not add radeon to the configuration.Use the module parameters on the kernel commandline method to ensure amdgpu works as expected. ![]() Reboot between each step to confirm it works before moving to the next step: The kernel may still probe and load the radeon module depending on the specific graphics chip involved, but the module is unnecessary to have loaded after confirming amdgpu works as expected. When building or compiling a kernel, CONFIG_DRM_AMDGPU_SI=Y and/or CONFIG_DRM_AMDGPU_CIK=Y should be set in the config.ĭisable loading radeon completely at boot Make sure modconf is in the the HOOKS array in /etc/nf and regenerate the initramfs.Ĭompile kernel which supports amdgpu driver Options amdgpu cik_support=1 /etc/modprobe.d/nf options radeon si_support=0 etc/modprobe.d/nf options amdgpu si_support=1 MODULES=(amdgpu radeon).Ĭreate the configuration modprobe files in /etc/modprobe.d/, see modprobe.d(5) for syntax details.įor Southern Islands (SI) use option si_support=1, for Sea Islands (CIK) use option cik_support=1, e.g.: Make sure amdgpu has been set as first module in the Mkinitcpio#MODULES array, e.g.
