The following .config options in the kernel have worked around the issue I think: > CONFIG_FW_LOADER=y > # CONFIG_FIRMWARE_IN_KERNEL is not set > CONFIG_EXTRA_FIRMWARE="amdgpu/polaris12_ce.bin amdgpu/polaris12_mc.bin > amdgpu/polaris12_me.bin amdgpu/polaris12_mec2.bin amdgpu/polaris12_mec.bin > amdgpu/polaris12_pfp.bin amdgpu/polaris12_rlc.bin amdgpu/polaris12_sdma1.bin > amdgpu/polaris12_sdma.bin amdgpu/polaris12_smc.bin amdgpu/polaris12_uvd.bin > amdgpu/polaris12_vce.bin" > CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware" Testing with some of the OpenGL screensavers in xscreensaver seems to show reasonable performance (well, good enough for my needs: this is a work PC). I'm not sure that's the proper solution though. It at least confirms my firmware binaries are good though, otherwise I'm certain it wouldn't be working there either. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.
