--- Comment #16 from Timur Kristóf <ven...@msn.com> ---
Hi,
After some more experimentation it seems that increasing the highest mclk
voltage above 900 mV and setting all other voltages in pp_od_clk_voltage in
such a way that they remain below 1000 mV, is a viable workaround that makes
the GPU stable.
Here is what I do to achieve this:
echo "2" > /sys/class/drm/card0/device/pp_sclk_od
echo "2" > /sys/class/drm/card0/device/pp_mclk_od
echo "s 0 300 750" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "s 1 588 765" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "s 2 952 900" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "s 3 1041 970" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "s 4 1106 970" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "s 5 1168 970" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "s 6 1209 970" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "s 7 1244 970" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "c" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "m 0 300 750" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "m 1 1000 850" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "m 2 1750 970" > /sys/class/drm/card0/device/pp_od_clk_voltage
echo "c" > /sys/class/drm/card0/device/pp_od_clk_voltage
After running this script, I can play on the GPU for several hours and I don't
see the hang happening anymore.
