Subject: drm/amd/pp: Add OVERDRIVE support on Vega10 (v2)
Git-commit: c5a4484941be553b37facd681daf990d040cce81
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
when bit14 in module parameter ppfeaturemask was set.
od feature will be enabled on Vega10 except vbios not support.
user can read od range by reading sysfs pp_od_clk_voltage,
cat pp_od_clk_voltage
OD_SCLK:
0: 852Mhz 800mV
1: 991Mhz 900mV
2: 1138Mhz 950mV
3: 1269Mhz 1000mV
4: 1348Mhz 1050mV
5: 1399Mhz 1100mV
6: 1440Mhz 1150mV
7: 1500Mhz 1200mV
OD_MCLK:
0: 167Mhz 800mV
1: 500Mhz 800mV
2: 800Mhz 950mV
3: 945Mhz 1000mV
OD_RANGE:
SCLK: 852MHz 2200MHz
MCLK: 167MHz 1500MHz
VDDC: 800mV 1200mV
and can configure the clock/voltage by writing pp_od_clk_voltage
for example:
echo "s 0 900 820">pp_od_clk_voltage to change the sclk/vddc
to 900MHz and 820 mV in dpm level0.
echo "r" to change the clk/voltage to default value.
echo "c">pp_od_clk_voltage
to commit the change
v2: squash in warning fix (Alex)
