Either that or set pi->mem_gddr5 = adev->mc.vram_type == AMDGPU_VRAM_TYPE_GDDR5; > > Also, double check that the gmc6 module properly sets vram_type. See the gmc 7 module for reference. > I see. vram_type is already inited as gmc_v6_0_convert_vram_type(tmp) in early_init of gmc 6. Good to know, thanks. Rui
