Hi, In si_dpm.c, si_populate_sq_ramping_values function, It should be SISLANDS_DPM2_SQ_RAMP_LTI_RATIO instead of NISLANDS_DPM2_SQ_RAMP_LTI_RATIO. ---- Moreover should it be: if (SISLANDS_DPM2_SQ_RAMP_LTI_RATIO > (LTI_RATIO_MASK >> LTI_RATIO_SHIFT)) instead of: if (NISLANDS_DPM2_SQ_RAMP_LTI_RATIO <= (LTI_RATIO_MASK >> LTI_RATIO_SHIFT)) ---- The previous does disable "sq ramping" for good on all SI, expected? regards, -- Sylvain _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
