Stoney looks like it might use the tonga or carrizo firmware. # cd /lib/firmware/amdgpu/ # ls *tonga* *carr* carrizo_ce.bin carrizo_mec.bin carrizo_sdma1.bin carrizo_vce.bin tonga_mc.bin tonga_mec.bin tonga_sdma1.bin tonga_uvd.bin carrizo_me.bin carrizo_pfp.bin carrizo_sdma.bin tonga_ce.bin tonga_me.bin tonga_pfp.bin tonga_sdma.bin tonga_vce.bin carrizo_mec2.bin carrizo_rlc.bin carrizo_uvd.bin tonga_k_smc.bin tonga_mec2.bin tonga_rlc.bin tonga_smc.bin
