This is supported by Sienna Cichlid, Navy Flounder and Dimgrey Cavefish. For these ASICs, the target voltage calculation can be illustrated by "voltage = voltage calculated from v/f curve + overdrive vddgfx offset". V2: limit the smu_version check for Sienna Cichlid only Here are some sample usages about this new OD setting: 1. Check current vddgfx offset setting by cat /sys/class/drm/card0/device/pp_od_clk_voltage ... ... OD_VDDGFX_OFFSET: 0mV ... ... 2. Set new vddgfx offset by echo "vo 10" > /sys/class/drm/card0/device/pp_od_clk_voltage cat /sys/class/drm/card0/device/pp_od_clk_voltage ... ... OD_VDDGFX_OFFSET: 10mV ... ... 3. Commit the new setting by echo "c" > /sys/class/drm/card0/device/pp_od_clk_voltage Signed-off-by: Evan Quan <evan.quan@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |
