drm/amd/pm: smu_v14_0_0: use SoftMin for gfxclk in set_soft_freq_limited_range

2026-06-03T18:57:46+00:00

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.

drm/amd/pm: zero unused SMU argument registers

2026-06-03T18:51:59+00:00

SMU messages may use fewer arguments than the available argument registers,
the previous code only wrote used registers and left the rest unchanged,
so stale values from a prior message could persist.

Write all argument registers for each message and zero the unused tail
to keep command arguments deterministic and avoid unintended carry-over.

drm/amd/pm: fix smu13 power limit default/cap calculation

2026-06-03T18:50:58+00:00

smu_v13_0_0_get_power_limit() and smu_v13_0_7_get_power_limit() mix
runtime power_limit with PP table limits when reporting default/min/max.

When current power limit query succeeds, default_power_limit was set to the
runtime value instead of the PP table default, and min/max could be derived
from inconsistent bases (MsgLimits/runtime), leading to incorrect cap info.

Use SocketPowerLimitAc/Dc as the PP default base (pp_limit), keep
current_power_limit as runtime value, and derive min/max from pp_limit with
OD percentages.

drm/amd/pm: apply SMU 13.0.10 workaround during MP1 unload

2026-06-03T18:50:40+00:00

On SMU v13.0.10, sending PrepareMp1ForUnload with the default
parameter may leave the device in an inaccessible state. This can
affect runtime power management and partial PnP flows.
e.g: kexec, driver unload, boco/d3cold.

Pass the required workaround parameter 0x55, when preparing MP1 for
unload on SMU v13.0.10, keep the existing behavior for other SMU
versions.

drm/amd/pm/si: Disregard vblank time when no displays are connected

2026-05-27T16:00:03+00:00

When no displays are connected, there is no vblank
happening so the power management code shouldn't
worry about it.

This fixes a regression that caused the memory clock
to be stuck at maximum when there were no displays
connected to a SI GPU.
