drm/amd/pm: disable OD_FAN_CURVE if temp or pwm range invalid for smu v14

2026-03-24T17:54:42+00:00

Forcibly disable the OD_FAN_CURVE feature when temperature or PWM range is invalid,
otherwise PMFW will reject this configuration on smu v14.0.2/14.0.3.

example:
$ sudo cat /sys/bus/pci/devices//gpu_od/fan_ctrl/fan_curve

OD_FAN_CURVE:
0: 0C 0%
1: 0C 0%
2: 0C 0%
3: 0C 0%
4: 0C 0%
OD_RANGE:
FAN_CURVE(hotspot temp): 0C 0C
FAN_CURVE(fan speed): 0% 0%

$ echo "0 50 40" | sudo tee fan_curve

kernel log:

drm/amd/pm: Return -EOPNOTSUPP for unsupported OD_MCLK on smu_v13_0_6

2026-03-23T18:48:52+00:00

When SET_UCLK_MAX capability is absent, return -EOPNOTSUPP from
smu_v13_0_6_emit_clk_levels() for OD_MCLK instead of 0. This makes
unsupported OD_MCLK reporting consistent with other clock types
and allows callers to skip the entry cleanly.

drm/amd/pm: Skip redundant UCLK restore in smu_v13_0_6

2026-03-23T18:48:45+00:00

Only reapply UCLK soft limits during PP_OD_RESTORE_DEFAULT when the
current max differs from the DPM table max. This avoids redundant
SMC updates and prevents -EINVAL on restore when no change is needed.
