In smu_v14_0_0_set_soft_freq_limited_range(), the gfxclk floor is programmed via SetHardMinGfxClk together with SetSoftMaxGfxClk. Under power_dpm_force_performance_level=high this pins HardMin to peak gfxclk. In PMFW arbitration HardMin has higher priority than SoftMax, so the firmware thermal/PPT throttler cannot clamp gfxclk via SoftMax once HardMin is set to peak. Replace SetHardMinGfxClk with SetSoftMinGfxclk so the driver still requests peak performance but the firmware throttler retains the ability to clamp gfxclk under thermal/PPT pressure. SoftMax handling is unchanged and no other clock domains are affected.
