<pre>RX 480.
I noticed a while ago that overclocking didn't work on
drm-next-4.17-wip/drm-next-4.18-wip, but now it's gotten into mainline.
With linux 4.16.3 overclockling works fine.
With 4.17-rc1 the setting doesn't "stick" and the clocks aren't increased:
root@c-pc ~ # cat /sys/class/drm/card0/device/pp_sclk_od
0
root@c-pc ~ # cat /sys/class/drm/card0/device/pp_dpm_sclk
0: 300Mhz *
1: 608Mhz
2: 910Mhz
3: 1077Mhz
4: 1145Mhz
5: 1191Mhz
6: 1236Mhz
7: 1288Mhz
root@c-pc ~ # echo 2 > /sys/class/drm/card0/device/pp_sclk_od
root@c-pc ~ # cat /sys/class/drm/card0/device/pp_sclk_od
